Uberman's sleep schedule

Over the past month, I've managed to convert my sleep cycles to something called the Uberman's sleep schedule. The end result is that I am sleeping roughly three hours a day. How did I do it? Is it safe?


Background

The Uberman sleep schedule is a method of organizing your sleeping time to maximize your REM sleep and minimize your non-REM sleep. The goal of the sleep cycle is that you are actively in REM sleep within a couple of minutes of falling asleep and remain in that state until you awaken. I originally read about the schedule on everything2.

In essence, someone utilizing the Uberman sleep schedule is actively modifying their sleeping habits so that they can immediately jump from waking to a few minutes worth of stage 1 sleep straight to stage 5 REM sleep, as described in this discussion of sleep stages.

It is important to note that there are no studies as to the long-term physical or physiological impact of this sleep cycle. I really don't know if this cycle is causing long-term damage to myself or not, and if this concerns you, I wouldn't attempt the cycle. However, the benefits are fantastic.

The Uberman's Sleep Schedule

Sleeping Hours
The Uberman's sleep schedule revolves around forcing yourself to rely on six twenty to thirty minute naps spread throughout the day for your daily dose of sleep. I stuck to thirty minute naps, currently having them starting roughly at 2 AM, 6 AM, 10 AM, 2 PM, 6 PM, and 10 PM every day.

How & Why It Works
Over the course of a normal eight hour sleeping period, your body moves through a continuous cycle of five distinct sleep stages. Of these, stage 5 REM sleep has been found to be the part of the cycle that provides the benefits of sleep for your mind.

Essentially, the trick of the Uberman's sleep schedule is to trick your mind into entering REM sleep as soon as you drift into a sleeplike state. Unfortunately, the only real way to do this is through sleep deprivation of sorts.

Adjusting To This Schedule
Adjusting to this schedule (as you might imagine) will make you feel like you've put your body and mind through a blender for a few weeks. Here are some general tips for adjusting that I found to be greatly helpful.

  • Do the adjustment when you are in complete control of your schedule. I converted to the cycle during a three week vacation; it would have been impossible to get through a normal work day while adjusting to this cycle. I was by and large a zombie.
  • Find a large project to work on while adjusting. If you don't keep busy, you will revert to a normal sleep cycle. In my first failed attempt at switching (on vacation more than two years ago), I didn't have an ongoing project to keep me focused.
  • Use physiological "tricks" to teach your body the cycle. I found that using a dawn simulation trick worked nicely. Every time I went to lay down, I set my monitor to wait thirty-two minutes, then begin running a program that had a strobe effect along with some excessively loud music. I also used two alarm clocks, and during the day I would adjust my blinds such that the sun would start shining in my face roughly a half an hour later. These would force me to become somewhat conscious for a while, which was all I needed to keep going.
  • Days 3 to 10 are the hardest and least productive. I spent the adjustment period working on two projects, one involving programming and another involving writing. At the start of day three, I stored a backup of these projects because I knew that my thought processes were starting to become nonsensical and bizarre. For the next week, I continued to "work" on the projects, but utterly failed to make any sensible progress (interestingly enough, the fiction I wrote in this period was entertaining in a Thomas Pynchon meets The Electric Company kind of way). Don't expect to be hugely useful during the actual forced adjustment to compressed REM sleep.
  • Convert to a more nutritious diet. I've found that drinking a great deal of orange and apple juice makes the Uberman schedule easier to follow, as does eating plenty of vegetables and avoiding fatty foods like the plague.

You will discover that after day ten or so, you will automatically begin waking after about thirty minutes. Quite often, I find that when a dream ends, I just awaken automatically. Although I still use an alarm clock, I now do my 10 AM, 2 PM, and sometimes 6 PM naps at work on my breaks without an alarm and have no problem waking up from them, feeling utterly refreshed.

Benefits

The obvious first benefit is more free time. I currently clock in between two hours and fifty minutes and three hours and ten minutes of sleep per twenty four hour period. Compared to my previous sleep cycles (roughly nine hours a night), I have an incredible amount of time to do things that I wished I had time to do before I switched.

Although the first benefit is pretty much the only reason you need, I also found that switching to this cycle makes me feel generally healthier. As I noted, I started off this "experiment" by switching to a more healthy diet rich in fruits and vegetables. After my body finally adjusted to the quick batches of REM (about day eight or nine), I began to feel truly GREAT! I actually feel more energetic at this point than I did before this started.

Drawbacks

One drawback is that I hit a wall if I stay up for more than about five hours without a twenty to thirty minute nap. My concentration and energy seem to vanish in a matter of minutes and I absolutely have to go take a nap. This can create some problems in social situations, but one can somewhat shuffle the naps around to adjust for this.

Another drawback is that my appetite is substantially larger and I will often crave strange things that I don't recall craving in the past. One great example of this is grape juice; I now drink this regularly, but before I switched I don't recall ever wanting it. My speculation is that my body isn't producing enough of some chemical that it would normally produce in stages 3 and 4 deep sleep.

Other Effects

One particularly noteworthy effect (I consider it a benefit, but others might consider it a drawback) is that all of my dreams are very intense and I find myself remembering them as well, down to minute details. Personally, I don't have any difficulties handling the imagery that my dreams produce, but many people have difficulties with their dreams in a normal sleep schedule - if that is the case, Uberman is simply not for you.

Conclusion

Uberman's sleep schedule is a potentially dangerous way to increase your waking hours. Although I found success with it to this point, there still may be physical and psychological dangers that I have not yet met, and there may be grave difficulties for others attempting the cycle.

if this guy has a sleep schedule, that can save me ONE MINUTE of sleep per night i want to know about it. While it appears hard to implement, and shares common traits with my existing sleep schedules (both work/ relaxation schedules)...i dont care if this is a kuro5hin board, a journal, slashdot, or possibly some random 404 . i dont care. we, the caffine addicted, code-creating/otherwise waveslaves could use just that extra few minutes more than anything...and there is a high number of us here.

the only thing my life is missing is time...everything else i can work with...but i do not have enough time...

I would perhaps never have heard of this otherwise. I don't know that I'll ever do it, but it's something to think about.

Of course, it's not right for everyone - how many of us have jobs that we can take 30 minute naps throughout the day when needed? Okay, never mind. ;]

heh, sorry. reference to a Seinfeld ep where Kramer decides that in order to be more productive, he will only sleep for about 3 hours/day (in short naps).

of course, it doesn't work out so well - he's in the "adjustment" phase, and he soon realizes that 1) he can't stay awake, and 2) his friends aren't awake when he is, and he's bored.

Good story (3.93 / 16) (#9)
by Hopfrog on Mon Apr 15, 2002 at 10:51:07 AM EST

You are trying out an experiment without knowing what the affects are, innit?

Well, I know that you can train yourself to wake up and sleep at particular times. So people, don't be afraid of that. Without an alarm clock, I wake up at 7:00 dot every morning during school time. It did it this way: About 2 weeks before school starts, I go to sleep at about 9, rather than the usual 11 or 12. I lye awake for a long time, but keep in mind that I want to wake up by 7:00. I also look at the clock a lot. My sleep on that first night is usually uneasy and light, but I wake up a few minutes before 7:00, usually around 6:45. The hard part is not falling asleep again. Do this for about 5 days, and you will automatically wake up by 7. Don't forget to look at the clock before you go to sleep.

The reason your dreams are intense is that they are always intense. It is just that you have more time to forget them if you go through the normal sleep cycle, and only wake up slowly.

I have also discovered that if you lounge around in bed for hours, it makes you much more tired during the day. I don't know why, I have just observed this effect on me. Wake up early, and start moving early, and you will stay active.

And as to the technique: I just might do this. I have the bad habit of working very late, or waiting up for late shows, so it would be good to compensate in some way for it. Or maybe I should just take a siesta.

Behavioral Psychology (4.75 / 8) (#31)
by Elkor on Mon Apr 15, 2002 at 01:16:14 PM EST

I have also discovered that if you lounge around in bed for hours, it makes you much more tired during the day.

This is caused by conditioning. Since bed is where you sleep (for most people) your body expects to sleep when you are in bed. So, if you lounge around, your body prepares for sleep. If you don't sleep, your body has trouble adjusting back because it began producing the chemicals produced during a normal 6 hour sleep cycle and they are still in your system.

If you develop a habit in a particular location, simply being in that location can begin to trigger the habit. For Americans, a good example of this is snacking while watching TV. Many families eat dinner in front of the "Boob Toob." The body becomes conditioned to expect food if you are watching TV. Thus, if you start watching TV, you feel like eating. You aren't really hungry, your body just expects you to feed it.

For this reason my Psych proffessor suggested to compartmentalize your life and establish routine. Never eat in front of the TV or in bed if you are trying to lose weight. Don't read in bed if you have trouble sleeping, because the body gets mixed signals. "Ok, I'm in bed. Do I read or do I sleep?"

He didn't really have an answer to the "Where do you have sex?" question. :?

Intense Dreaming (4.00 / 2) (#74)
by The Solitaire on Mon Apr 15, 2002 at 05:32:07 PM EST

Actually, one reason for intense dreaming is that the body tries to conserve REM sleep. If you deprive the body of REM for a time (selectively, this can be done using an EEG hookup), then then next time you go into the REM stage, your body tries to make up for lost time... in other words, you sleep (or REM?) more intensely. Sorry I can't give more specifics right now, but it has been some time since I studied sleep in depth.

For my last 3 years of college, I followed a similar sleep pattern. I slept twice a day, basically 2:00-5:30 AM and PM. Now 15 years later I think I'd be much more productive if my job would allow me this type of sleep schedule.

I have adjusted to a 6:00AM to 3:00PM work schedule and often take a 1 hour nap after work. My problem is if the nap goes longer than that. Then my night sleep schedule gets messed up for 4 days or so.

Interesting... (4.44 / 9) (#17)
by BadDoggie on Mon Apr 15, 2002 at 11:40:16 AM EST

I prefer 4x45-min. to 6x30-min. Edison eschewed long periods of sleep, preferring short naps, often taken in the lab.

Of course, I was never a big sleeper to begin with. Wouldn't/couldn't nap in kindergarten, In high school, I slept about two or three hours every two days; in college no more than three hours a day on average (if I passed out for six hours from intake, I wasn't gonna be sleeping again for a while). I still normally can't sleep four hours a night (maybe five, but only if alcohol is involved).

The big problem is what to do in the wee hours. TV is incredibly bad, you can't play guitar, can't listen to music while writing/coding, someone else is still sleeping in the bed, can't play pinball... It's great for students and singles (especially if the walls are thick), but as much as I don't care for sleeping, I care less for getting out of the bed she's still in. (:

woof.

Mania? (4.00 / 4) (#25)
by X3nocide on Mon Apr 15, 2002 at 12:50:16 PM EST

The original post looks like a method of inducing mania (the opposite of depression), and if you haven't allready, you might talk with a psychologist or doctor about having short sleeping habits and the consequences. The workings behind the solutions are mysterious, nobody knows why lithium salts seem to cure manics. It seems to be related to a neurotransmitter imbalance, and the situation may not be desireable over the long term. My experience with this disease is mostly associated with Manic-depression aka bipolar disorder, where mania really becomes a problem. Start up a consulting company one month, have difficulty getting out of bed the next.

I am not a doctor however, and this could be something completely different, or not an issue at all.

As a person with bipolar tendencies, I don't see why this chould be avoided. My "down" days are a bitch, something I just have to bully through, but my "up" days are frikkin' amazing. I feel like a machine. I can lift at the gym like a monster or if I'm playing witha band it's like my guitar strings are made of butter and the guitar just plays itself. If there is a way to artificially increase my manic time (heavy drinking can do it pretty well) I'd be all for it. So it might take a year, or a decade, off my life. For the rewards, that's a risk I'm willing to take.

I tried this once (4.00 / 2) (#41)
by wiml on Mon Apr 15, 2002 at 02:36:41 PM EST

in college, after hearing about da Vinci. I used the "fifteen minutes every four hours" schedule. It worked, to a point: I was functional, and didn't suffer most of the problems of sleep deprivation. But my god did I want a full night's sleep. After a while I gave in to my craving.

As for the question of what to do when you're awake in the small hours --- I can't believe people here are asking that question. There's the net, for one; you can catch up on all your favorite web sites, usenet groups, and CVS commit logs. Hacking, duh. Reading a good book. Or a bad one. Take a walk or meditate. Do some amateur astronomy. (In school, of course, I could use this time for homework.)

It's interesting to see this article today, as just yesterday I was talking to a friend about this sleep experiment and thinking of giving it another go. I learned recently that as well as da Vinci, Bertrand Russell used this sleep schedule. (I've never heard it called "Uberman's Sleep Schedule" before --- sounds stupid, IMHO.)

Thelonius Monk (4.45 / 11) (#23)
by wbajzek on Mon Apr 15, 2002 at 12:26:44 PM EST

If the liner notes in Thelonius Monk's "Misterioso" album are to be believed, Monk would only sleep a few minutes here and there. Presumably he spent most of his life like that.

IIRC, he suffered from severe mental problems later on in his life, however, and considering that there are studies that show that sleep deprivation is really bad for you, I wouldn't be surprised if it was a large part of the cause. I would be careful about doing this for a long time.

I remember seeing something on the Discovery Channel a few years ago about some guy that had a radio telethon thing where he stayed awake for (I think) 13 days straight. He had to have lots of help to keep him awake, and he had problems with hallucinations, and although he seemed to recover fine with 24 hours of sleep afterwards, his health and sanity declined over the next 6 months, and he died.

I can't remember who he was or what show I saw this on, though.

Yes, you'd be correct. Monk suffered from a myriad of psychological problems. Mild schitzophrenia and bipolar disorder were some of these. His vivid and sporatic playing patterns seem to emulate his sleeping patterns, and erratic life in general.

by gazbo on Mon Apr 15, 2002 at 01:21:12 PM EST

I think you're right about it being 13 days, or certainly in that area. Eventually it was impossible for him to stay awake.

As for the bit about him going insane and dying? That just screams 'urban legend' to me. I've not heard anything like that, and I think 13 days of deprivation is not long enough to have such an effect.

As for this Uberman method, it doesn't sound too dangerous. In the news recently was the woman who sailed single handedly around the world (or some similar distance) and she followed a similar pattern through necessity. The general concensus is that the REM sleep is all that is really necessary.

This wasn't something I heard from a friend of a friend. This was in a documentary on the discovery channel, and I believe they even showed footage of him in the hospital near the end of his life.

I didn't say he went insane, I said his sanity declined. there's a difference. But he did die 6 months later.

A little clarification (5.00 / 2) (#37)
by toganet on Mon Apr 15, 2002 at 01:49:48 PM EST

Here's some info a quick Google search gleaned:

"In January 1959, a 32-year-old disc jockey, Peter Tripp, decided to go without sleep for 200 hours as a publicity stunt to raise money for charity. Undaunted by experts who warned of the risk of death, Tripp persevered. When he found it extremely difficult to stay awake after 135 hours, he turned to stimulants. The stimulants (amphetamines) altered his perceptions: Specks of dust became insects; a bureau drawer burst into flames. Yet he hosted his show, "Your Hits of the Week," between 5 and 8 p.m. each day, without giving any hint of what he was enduring. After 201 hours without sleep, he slept for 13 hours; the only symptom he experienced as a result of his ordeal was a slight depression that lasted a few months." (http://www.nctc.tec.oh.us/Webpub/Blewis/PSY%20CHAPTERS/supplement_(sleep).htm)

"Robert McDonald of California holds the world record for sleeplessness; in 1986 he rocked in a rocking chair for 453 hours, 40 minutes (McFarlan, 1991)." (ibid.)

Here is a Q&A from Scientific American. To quote the First part of the answer to the question 'How long can humans stay awake?' with added emphasis:
The easy experimental answer to this question is 264 hours (about 11 days). In 1965, Randy Gardner, a 17-year-old high school student, set this apparent world-record for a science fair. Several other normal research subjects have remained awake for eight to 10 days in carefully monitored experiments. None of these individuals experienced serious medical, neurological, physiological or psychiatric problems......all experimental subjects recovered to relative normality within one or two nights of recovery sleep.
Nothing important missed out, and no mentionin the article about untimely deaths.

I've followed some other links, and all say the same thing. Scintific American was just the most authoritative.

I am *very* sceptical about almost any information these days - nothing personal, just heard the tale about rockets being attached to a car once too often.

Just look at the second paragraph (3.50 / 2) (#97)
by Detritus on Mon Apr 15, 2002 at 06:46:16 PM EST

Look at the second paragraph of that same Scientific American site:

The more difficult answer to this question revolves around the definition of "awake." As mentioned above, prolonged sleep deprivation in normal subjects induces altered states of consciousness (often described as "microsleep"), numerous brief episodes of overwhelming sleep, and loss of cognitive and motor functions. We all know about the dangerous, drowsy driver, and we have heard about sleep-deprived British pilots who crashed their planes (having fallen asleep) while flying home from the war zone during World War II. Randy Gardner was "awake" but basically cognitively dysfunctional at the end of his ordeal.
See the Q&A at http://www.sciam.com/askexpert/biology/biology60/

Even though the Uberman's system gives you extra time to do things, I'd imagine you aren't nearly as productive during that time than you would be if you'd gotten a full night's sleep. I'm imagining someone with severely impaired abilities; maybe they're unnoticeable, but you will start to feel them as time progresses.

In other words, all the extra time will be compensated by loss of functionality, and in effect you could be just as productive if you work less time but with greater accuracy and mental agility.

I am reminded of pretty much the exact oposite, narcolepsy. That is both unfortunate and yet incredibly amusing (schadenfreude is alive and well). These people suffer from overwhelming tiredness, and are prone to falling asleep frequently. It is overplayed in the movies, but the effects are still pretty incredible.

The funniest I saw was a documentary that showed some narcoleptic dogs. They'd be running in a field playing, retrieving a stick or whatever; mid stride, they'd just...stop. Depite running at top speed, they'd suddenly just go limp and tumble to the ground. Both pitiful and extraordinarily amusing at the same time.

Death from sleep dep (none / 0) (#145)
by The Solitaire on Tue Apr 16, 2002 at 01:04:45 AM EST

First, I have to say that I have never heard of any human dying from sleep deprivation. They just wouldn't be able to keep it up for that long. And it would be highly unethical for a researcher to perform such an experiment.

However, death from sleep deprivation is a well know fact for rats. What they die of is not entirely clear. The one reference I have on the topic is that they succumb to opportunistic systemic infection - essentially, their immune systems fail.

Reference: Everson (1995). Functional consequences of sustained sleep deprivation in the rat. Behavioural Brain Research, 69, 43-54.

Insanity from sleep dep is no joke or myth (5.00 / 1) (#64)
by Kasreyn on Mon Apr 15, 2002 at 04:57:06 PM EST

The governments of Hitler and Stalin, as well as numerous Central American and African despotisms, and probably the CIA, have used this technique. Keep someone sleepless for a week to put pressure on him. Two weeks, he'll sell his mother to the devil for a nap. A whole month, you will literally drive him insane. It's possible that gradual deprivation over time may result in the same thing, though it's not really known. Next time I see a my sleep specialist (hooray for sleeping disorders =P), I'll ask him about the safety of the Uberman method.

If it's safe, I have to say I would give my left nut to be able to only waste 3 hours a day on sleep. And I'd get such a kick out of being active long after others collapse. ^_^ The thing I have always hated most about life is that I spend so much of it unconscious (I sleep 9-10 hours a day =( ). At the moment I can't afford to take time out to adapt to this system, though. Furthermore, I'm worried that it may result in various mental disorders, or worsening of the ones I already have. =P Maybe I'll try it someday.

I read an article many years ago, maybe in scientific american, about an experiment on rats similar to what you describe, but every time the rats fell asleep, they injected them with a mild form of speed to keep them awake.

As Promised! (5.00 / 1) (#134)
by The Solitaire on Tue Apr 16, 2002 at 12:11:54 AM EST

Okay, I have some of my sleep research in front of me. All the references I give are from "Behavioural Brain Research", in a special issue on the function of sleep.

According to a literature review in one study, death from sleep deprivation occurs on average around 21 days. The particular study presented states that it occurs on average at 16 days.

In another paper, rats were deprived of all sleep, paradoxical (REM) sleep, and non-rem sleep. The first group died after between 2 and 3 weeks. The REM deprived group died after an average of 5 weeks. NREM deprived rats lived an average of 45 days. All of these figures are from the paper itself, I would be more specific if I could.

Contrary to what another poster mentioned, sleep deprivation in rats is not achieved through the use of drugs. Rather, they use a rotating disk, hooked to an EEG. If the rat starts falling asleep (or goes into the specific stage being deprived) the disc turns, and the rat has to walk, thus waking up. To ensure that the walking isn't the problem, the rats are in what is called a "yoked-control" situation. In other words, there is another rat that is standing on a disc, and is forced to walk whenever the *other* rat is falling asleep. Other than this constraint, it is free to sleep whenever it likes. In addition, they attempt to control for circadian rhythms, using special lighting conditions. Ample food and water are also available.

I won't go into more detail here, for reasons of brevity, but the two papers I mentioned are:

  1. Rechtschaffen & Bergmann (1995). "Sleep deprivation in the rat by the disk-over-water method", Behavioural Brain Research, 69, 55-63.
  2. Everson (1995). "Functional consequences of sustained sleep deprivation in the rat", Behavioural Brain Research, 69, 55-63.

Long term sleep deprivation. (1.50 / 2) (#138)
by mindstrm on Tue Apr 16, 2002 at 12:37:07 AM EST

Firstly, all reports of hallucination due to sleep dep are usually due to the stimulants used to deprive someone of sleep.

You do lose your ability to remember color, your short term memory goes to crap, and you tend to have little microsleeps any moment you let your guard down.. but sleep dep is NOT that bad.

It's usually the drugs that are used to stay awake that do the damage.

I remember sleep dep experiments where they talked about vivid hallucinations.. leading to the myth that not sleeping causes severe hallucinations. It's not true.

Uhhhh... (4.00 / 1) (#144)
by The Solitaire on Tue Apr 16, 2002 at 12:55:18 AM EST

Generally, as I understand, modern sleep deprivation experiments are not done using drugs. That would wholly and totally invalidate the study. Generally, from my understanding, people are kept awake by forcing mild physical exertion. Certainly, rat studies are done this way (for example the disc-over-water method... described in another post here).

I must agree with you on the hallucination front, however - people don't hallucinate. The explanation of the anecdotal stories of this that I have heard was that because your body tries to conserve REM sleep, you dream very intensely when you do finally fall asleep. Effectively, what happens is that people fall into a microsleep, have nearly immediate intense dreams, which wake them up.

As far as sleep dep being bad - it does, for a fact, kill rats. Whether that fact extends to humans is open to speculation... Experiments of this sort are hard to come by :)

Polyphasic Sleep (4.50 / 8) (#35)
by watchmaker on Mon Apr 15, 2002 at 01:29:17 PM EST

This is nothing new and revolutionary. I first heard it associated with Leonardo DaVinci. The periods I read about were 15 minutes every four hours. But as someone mentioned, Edison did this as well. Even Winston Churchill did something similar, sleeping in two shorter phases through the day.

The human body is fully capable of handling this type of sleep. It's how babies sleep for the first year of their lives. The downside is that, as the author says, you get regimented into a schedule. Get outside that schedule and you crash very quickly.

The upside? The author sleeps three hours a day instead of the "typical" 8.

Assume the author is 24, that's 50 years until the "average" life expectancy of 74.

3 hours * 365 days * 50 years = 54750 hours.

That's 6 years and about three months worth of functional life gained. (And I didn't even include leap years). Sign me up. I've always said that I could rule the world, but for a 26 hour day.

Anyway, this guy was doing this for years, while still going to the gym and doing all kinds of other activities. My friend claimed that the guy looked like he was 20 years older than he really was.

Makes one wonder if sleep deprivation has its tolls on the body's aging processes in some way or another.

by illaqueate on Mon Apr 15, 2002 at 03:16:30 PM EST

I'm not one of these light sleepers but I have to say I am skeptical about recovery from strenuous physical activity and light sleep (<=3 hours). I'm not questioning whether one can endure it; rather that someone who sleeps longer periods (>3 - 7 hours) will have the benefit of a period of inactivity & regeneration that comes with the physical paralysis induced by sleep.

It is an interesting topic. Anyhow, I found a page that describes strategic napping in solo yacht races and they sleep 4.5 hours a day in 20 minute intervals but also require 2-3 longer periods of sleep during the week.

They do it out of necessity, but is it really optimal? I found a page that suggests that "Afternoon increase in sleep propensity suggests that the human sleep-wake system is designed for two sleep periods." They then intimate that a "siesta" (afternoon nap) is "useful in managing some of the effects of sleep loss". I can attest to this as I do sometimes nap in the afternoon -- although it's mostly rest not sleep.

But, on the other hand, they show that after naps there is an effect called "sleep intertia" where there are significant effects on cognitive performance after sleep periods, suggesting that frequent naps during the day are not optimal.

Finally, the original article cites famous short sleepers such as Winston Churchill. The information I found indicates that Churchill slept 3-4 hours a night and napped during the day. It isn't anything like the method described in the uberman sleep article. Is anyone aware of any studies on this or similar methods that I could read?

Persoanlly, I think one should sleep whenever one starts to get tired. Screw your employer... naps come first! I think people have forced themselves into so many artificial situations that we never have time for naps anymore... schedules, meetings, deadlines, all kill the chance for a good nap. I say be more like cats! Eat when you get hungry, sleep when you get tired. You will find yourself more alert in your waking times. Well, do so as much as possible (reality prevents us to reach our true potentials). Okay, I'm done *grin*

Ummm... what makes you think that wolves sleeping habits should have any real bearing on the way we sleep? The indus dolphin sleeps in 4-60 second "micro-naps" for a total of 7 hours a day. Maybe we should sleep that way? If you really want to know how we "should" sleep, you should really examine the natural sleeping patterns of our closest relatives, the great apes. Of course, I don't put much stock in "shoulds" at any rate...

I had this kind of schedule forced on me... (4.50 / 6) (#48)
by Ron Harwood on Mon Apr 15, 2002 at 03:14:53 PM EST

Once upon a time I worked for a dot-com... and I ended up with a rather odd sleep schedule. (Long story short - insomnia combined with a pager and NT4/IIS servers)

The result? Hypoglycemia symptoms... I had a voracious appetitie, and if I didn't eat regularly (every couple of hours - and I skyrocketed to 245 lbs.) I got brain busting headaches and massive mood swings.

About 3-4 months after I quit - I was back to normal... and was down to 220lbs... 2 years later... I'm back down to 180lbs...

This is me though - your mileage may vary.

As mentioned in an ealier comment, I have a habit of sleeplesness. I found, too, that I eat alot, and that my eating habits change. Sugar seems to be the root of all evil, for me, in that case. I drink mainly water and coffee, sometimes unsweetened tea or juices. Whatever I am drinking, though, I drink it in great quanitites. I apparently require much more liquid then.
I eat alot more vegetables, although I think partially for their water content. To me there seems to be a connection between the fruits and mental health while being awak for long periods, whilst red meats seem to help physical exhaustion. Avoid, though, the fats in red meat. It seems the body is going into a mode where it exchanges food for sleep. I'm not sure how that would work, though. I think food digests better, and more fully, though for people who have been awake longer.

How strange.. (4.20 / 5) (#51)
by EggplantMan on Mon Apr 15, 2002 at 03:18:03 PM EST

Midway through this semester I adopted a somewhat similar sleeping strategy. Because workloads were heavy, I would stay up late finishing assignments. Then I would more often than not have to get up for an 8:30 class. This constraint forced me often to just go on maybe four hours sleep a night. To make up for this, I started to take a nap halfway through the day after classes. Eventually my sleep cycle drifted to three hours with two naps throughout the day.

I noticed the same problem you have - that after a certain number of hours I would just become dead tired, and also another one - I liked to call it 'The day that never ends'. Eventually I just felt like my life was one continual day and calendar days didn't really have any meaning to me except for handing in assignments.

The only reason I could do this was because I'm in residence, but I have found it interesting to see what happens to my sleep schedule when I'm in complete control of it. I'm back on a more normal schedule now, but it was useful while it lasted.

As to some concerns of muscular effects... I'm not a doctor whatsoever, but I work in an intensley physical field. I'm sure most will agree there are at least two forms of being tired. One is mental, the other is physical. I never had too much problem with being physically tired when I was in school. With my job now, I find I need at least one hour of sleep before work. Don't know if that helps anyone..

Found it: REM destroys muscle (5.00 / 6) (#120)
by Cal Bunny on Mon Apr 15, 2002 at 09:19:54 PM EST

Sleep is only partially beneficial to muscle growth. There is a stage of sleep called delta or slow-wave sleep. During this time hormones are released to build muscle tissue. After delta sleep you enter REM sleep. During that time cortisol is released and that actually catabolises muscle tissue. Body builders sleep for about 12 hours a day, but they sleep about 8 hours a night then take a couple naps throughout the day. This way they enter delta sleep but never enter REM sleep. There are a couple product on the market to help alleviate this problem: they call it Nocturnal Post-Absorptive Muscle Catabolism (NPMC). It seems that this sleep schedule that tried to quickly induce REM sleep would actually be very detrimental to muscle anabolism and induce heavy catabolism. The bunny doesn't like the sound of this.

Strange -- from "Age-Related Changes in Slow Wave Sleep and REM Sleep and Relationship With Growth Hormone and Cortisol Levels in Healthy Men"


"Increasing age was associated with an elevation of evening cortisol levels (+19.3 nmol/L per decade; P<.001) that became significant only after age 50 years, when sleep became more fragmented and REM sleep declined. A trend for an association between lower amounts of REM sleep and higher evening cortisol concentrations independent of age was detected (P<.10)." <br> summarizing that article one page writes:

"After the age of 25, men experience a decline in deep sleep that accompanied by a drop in GH production. GH deficiency is related to reduced muscle mass and strength, increased fat tissue, weakened immunity to infection, and other health declines."

further, in the article:

"The decline in slow wave sleep from early adulthood to midlife was paralleled by a major decline in GH secretion (-372 g per decade; P<.001). From midlife to late life, GH secretion further declined at a slower rate (-43 g per decade; P<.02). Independently of age, the amount of GH secretion was significantly associated with slow wave sleep (P<.001)"<br>

I can only access the little synopsis and only have your quotes to go on, so I don't know the whole story. It seems that the study was done to investigate the dynamic between aging and GH and cortisol production.

The study does seem to deny some of the claims of others when it says that as sleep became more fragmented, and therefor REM sleep decreased, that cortisol levels increased. However, it says that cortisol levels increased as a function of age.

The final quote you provide seems to feed what the article I read states: as slow wave sleep decreases, GH secretion decreases. The quotes you provide me with seem to imply that as you age, you get less slow-wave sleep. Am I reading that correctly?

by illaqueate on Tue Apr 16, 2002 at 03:29:33 AM EST

As I read it, it implies that there is no detrimental effect. Cortisol levels do not increase with REM-sleep. The theory behind it is that it regulates cortisol levels and hence is one of the reasons why affect is changed so profoundly by sleep. And from the brief reading I did it's generally not possible to select one or the other to be in any given period of sleep. If experiments are unable to separate the two, some special method to go into one or the other surely does not exist (not including drugs).

Safety / Evolution (4.37 / 8) (#53)
by Hobbes2100 on Mon Apr 15, 2002 at 03:33:51 PM EST

Just a question:

It seems to me that given our evolutionary history, having a "full eight hours of sleep" everynight would not have been very conducive to staying alive (both in the short- and long-terms).

Something like this Uberman program seems to be more in line with how I'd expect sleep to work "in the wild". So, I guess I'd be arguing that "since this is likely how we evolved, it is probably safe". Anyone know about anything about animals [perhaps primates] in the wild and their sleeping patterns? I have a bit of psychology background (but it's mostly cognitive) but next to nothing else related to this topic.

Anyone have something worthwhile to contribute?

Humans as well as many primates have been social animals for a long time. That means there has been someone around to watch our backs while we sleep. Homo Erectus was around at least as early as 600,000 years ago; not a massive amount of time on evolutionary scales, but still a lot, and that's not counting early forms of man.

Maybe there's something here, but I doubt anything short of a comprehensive investigation (perhaps possible in the next decade or two, given the current rate of the analysis of our own genome) will reveal it.

Actually, if you were to rid yourself of all sources of artificial light and eat a very healthy vegetable based diet, your eyesight would improve and you would be able to let your eyes adjust to near total darkness situations.

If there was an evolutionary need for better eyesight in homo erectus, then it most certainly was possible. Just because now we have artifial light that enables us to not use our eyes to their full potential, doesn't mean that our ancestor's had the same vision we do.

The human eye is amazingly sensitive (5.00 / 2) (#111)
by hairyian on Mon Apr 15, 2002 at 07:52:35 PM EST

I've recently been assisting on an observing run on a (serious) astronomical telescope. 10,000 feet up a mountain, strict lighting laws on street lights on the towns far below, miles of (unlit) sea surrounding the island and probably more bizarre things make La Palma one of the places which makes a good site for astronomical telescopes. The problem is light pollution: stray photons for light sources get caught by the CCD in the telescope (for example) and add to the noise in the image. Too much noise and faint objects are indistinguishable from the background 'mess' of random photons collected. The same thing happens with the human eye. I live in the middle of a sprawling city. Street lights leak light in all directions, vehicles do too. At most, on a clear night, I might just be able to see a few stars. I certainly don't see the dust clouds of the Milky Way and the handful of stars I do see are the brightest in the sky. Everything else is washed out by the random scattering of the lighting of the city. On La Palma I saw the Milky Way for the first time. At first, when I walked out on the roof of the observatory I saw very little: it was too dark. The brightest stars were there, as always, but it seemed all but pitch black. A few minutes letter things were quite different. By just the light of the half-moon and the stars I could see. I could see the terrain around the telescope, the clouds on the horizon and more stars than I've ever seen before. I also saw the Milky Way arcing across the sky. The moon was so bright that it was preventing me from seeing more detail then I could: it was drowning out some of the features because of it's brightness. The darkness is only dark because you think it is. In real darkness, there is a surprising amount of light - even starlight on a clear night is probably enough to move about safely, forridge a bit, perhaps even a bit of hunting. Something that sticks out: if there wasn't an evolutionary need to see in the dark, why would the human eye have such a huge dynamic range that you can look about during the brightest noon, but still see by starlight and moonlight?

Sure there's a need (though not an evolutionary one, as such a concept is nonsensical at best): take your average group of 50,000 BC men, sleeping in their primitive camp; there's a russle in the bushes, and a pack of wolves (or tigers, orangutans, elephants, pick your favorite nocturnal predator) leaps out; RUN OGG, RUN! So Ogg runs and, because his eyes are slightly better than Ugg's, he doesn't trip over the log and get eaten alive but instead survives the night, has lots of sex and numerous children, each with decent night vision. But that doesn't mean night vision was ever used for anything more than fleeing like crazy.

by theR on Mon Apr 15, 2002 at 09:14:23 PM EST

Of course you can see at night without electricity, even if you're used to it. But the way you see is a lot different. You don't see details or color nearly as well in low light as with more light. I imagine most of the things done in the dark were purely of necessity, like urinating, bowel movements, or hunting nocturnal creatures.

If you look at texts that were written by people on the American frontiers when America was first settled, I believe you will see that darkness was primarily a time of rest. There are always exceptions, but I've certainly never heard of the settlers or native peoples typically sleeping in any other way than what is considered the common one now, i.e. sleeping through the night.

Night Vision (none / 0) (#159)
by Cloaked User on Tue Apr 16, 2002 at 07:21:38 AM EST

But the way you see is a lot different. You don't see details or color nearly as well in low light as with more light.

There's a reason for that, especially the colour-blindness. Dredging up what I learnt in my "Physics of Nerve Cells and Networks" course, the light receptors in your eye come in two types, rods and cones. The cones are the ones that enable you to see colour, and are mostly concentrated around the focal point (just off centre of the back of your eyeball). The rods can not distinguish colours and are more densely distributed around the periphery of your "visual area".

As well as the differences in colour sensitivity, rods and cones differ in light sensitivity - rods require much lower light levels to function. This is why you don't see colours or details so well in low light conditions. Your cones don't have enough light to function properly, mucking up your colour vision, and you have fewer rods, mucking up detail perception.

As an interesting asside, some (most?) animals that see well in the dark (eg domestic cats) have relatively poor daytime vision and little or no colour vision, as their eyes contain far more rods than cones.

Of course, it's been a long time since I did any of this stuff, and it was only a single course in my third year at University - if anyone knows better, please feel free to correct me :-)


Cheers,

Tim

Diurnal Animals (4.66 / 3) (#86)
by The Solitaire on Mon Apr 15, 2002 at 06:03:50 PM EST

Ummm... there are plenty of non-social animals that sleep all night. Sleeping for extended periods is much older evolutionarily than man as a species, or even homo-erectus. What is interesting is that sleep seems to be so important that species that can't sleep for one reason or another develop very interesting ways of obtaining sleep. One example of this is the Indus Dolphin. The Indus Estuary is really really silt filled, and really fast moving. Thus, the dolphin has to swim constantly, or die. It has evolved to sleep in 4 to 60 second bursts... but it still sleeps 7 hours a day. Regular dolphins, which need to stay awake to breathe, sleep one brain hemisphere at a time - but they still sleep. I think that these examples should be adequate to show that sleep is important and messing around with it in this way is potentially very dangerous.

Stone-age sleep (4.33 / 3) (#115)
by dennis on Mon Apr 15, 2002 at 08:25:33 PM EST

I'm no expert, but here's my take on it after an anthropology degree and four weeks at a primitive-survival school...I don't remember ever discussing sleep patterns in class, so this is speculative.

Predators: Hunter-gatherers from early man to modern times have lived in small groups (often of only a dozen or two). That doesn't mean they didn't spend a lot of time alone, though - Native Americans sent individual scouts out for months at a time. If you're worried about predators, sleeping this way might be an advantage sometimes...but predators aren't as big a deal as you might think. A modern hiker will blunder right into a grizzly, but a skilled primitive will notice its presence long before, from tracks and the reactions of other animals (birds especially). He'll steer clear of its territory when selecting a shelter. Large predators are certainly a danger, but one that can be avoided with a good level of awareness. There are also ways to mask or remove your scent, if necessary, and all sorts of sneaky ways to bed down. A good hidden spot for the night is probably safer than a catnap in the open.

Weather will be an issue. If it's nice enough, you might nap when you feel like it, but if it's getting really cold at night you're going to want to spend that time in shelter. A good individual shelter has lots of insulation and just enough room to squeeze inside, so your body heat can warm it up nicely - so if you're in it, you're probably sleeping.

Nevertheless, I wouldn't be surprised if primitives did spend a lot of time awake at night, when circumstances permitted or required, because light is not as big an issue as you'd think either - even without a full moon. I got my first hint of this at the wilderness school, when they took us well out from camp one night, stripped to our shorts, and made us find our way back blindfolded while a guy in camp banged on a drum. Just moving by feel and intuition. Self-absorbed left-brained geek that I am, I had a hard time, but some people did pretty well, and the instructors could do that sort of thing with ease. Mix that sort of skill with a bit of starlight and you can get by just fine - as hairyian points out, humans actually see pretty well in the dark once we adjust to it.

The periods you spend not sleeping are used for your body to do maintance. Hence the comments about effects on muscle gain. As you sleep normally at first you dream little as your body does its work. As you sleep longer as the night goes on then longer periods of time are devoted to REM sleep. It seems like you are cutting away the body's time for self repair.

After several years of this you're probably going to notice the wearing effects which this is most likely having on your body.

I saw TV programme a while back that discussed spinal discs. Now, I'm no biologist, so I could be way off track here. It suggested that we get shorter during the day as these discs lose their volume due compression (squeezes liquid out?). They said the only way to replenish the discs is to sleep. Apparently with insufficient rest, heavy lifting can more easily result in back injury.

I've got to wonder how much sleep one's body needs to maintain it's self physically. Does this sleep schedule work for people who are very physically active?

We do indeed get shorter during waking hours, specifically the hours we spend in a non-horizontal position.
The shrinkage is due to the spine carrying your body weight, and this is 'fixed' by taking the weight off - by lying down for several hours. While asleep is a very convenient time. :)

I also found that switching to this cycle makes me feel generally healthier. As I noted, I started off this "experiment" by switching to a more healthy diet rich in fruits and vegetables.

So, those are two very different actions, either one of which I can imagine substantially changing the way you feel. How much of your feeling healthier do you suppose is related to the changed diet, how much to the changed schedule? Have you ever tried changing one but not the other?

I eat more or less as you describe - I don't eat meat, don't cook with a lot of fat, etc. When I'm eating out a lot, or eating someone's cooking that uses a lot of starches and fat, I know I feel much less alive after a few days, whether or not my sleep schedule changes.

by scatbubba on Mon Apr 15, 2002 at 05:29:09 PM EST

Do these 20 minute naps have to be full lay down, in the dark naps, or can you just put your head down on your desk? I'd love to try this, but with my pesky day job..... I could easily steal away to the library for 2 20 minute naps during the day, but will that be enough?

naps (none / 0) (#203)
by solri on Wed Apr 17, 2002 at 11:04:37 AM EST

Naps work for me, though only in the afternoon - any time after 6 p.m. leaves me feeling extremely groggy. If I can regularly get a twenty-minute siesta, my sleep needs go down from 7 hours to 6, sometimes less. I sometimes find it's better to take a nap on the couch rather than going to bed. I find being too comfortable in a dark room sends me into deep sleep, so when I wake up I feel as bad as if I've been woken in the middle of the night.

My sleep pattern (3.80 / 5) (#77)
by auraslip on Mon Apr 15, 2002 at 05:43:34 PM EST

This isn't a comment telling you about another sleep pattern that you might want to try. My sleeping pattern is horrible. I sleep 12 hours a day. I'm not in school and I don't have a job, and I have no freinds not in school. SO I tend to stay up all night. last night I stayed up untill 630, I only woke up 30 minutes ago. I really hate it. The thing was, at the begging of last week, I was going to bed at 12 because OF a vacation that weekend, and by now I've ruined it. It used to be a lot worse when I had counter strike on my computer. I think more then anything I'm addicted to sleep. :(

Pure Pseudo-Scientific Nonsense (4.84 / 13) (#80)
by The Solitaire on Mon Apr 15, 2002 at 05:47:18 PM EST

Sorry to burst people's bubble, but I find the so-called "scientific" underpinning for all this to be patently rediculous. I spent time a few years ago doing some relatively intensive study on the purposes of sleep, and the effects of deprivation. One thing that jumped out immediately was the assumption that REM sleep is the only important stage. THIS IS COMPLETELY UNTRUE. Research has consistently shown that both REM and stage 4 (also called deep sleep) are very important, and selective deprivation of either of them has consequences.

Now, I will admit, the current understanding of sleep is less than perfect. There is a general belief (possibly incorrect) that sleep is all about regeneration. One major reason for this view is that rats DIE if you sleep deprive them for approx 20 days or so (I can't remember the exact figure). As I recall, this also goes for selective deep sleep deprivation.

One more thing - this article seems to go against everything I know about circadian rhythyms. Effectively, your body has a 30-hour clock, which is reset by certain stimuli, such as light or eating. Usually the natural light/dark cycles reset this clock every 24 hours. Disrupting the clock has been associated with seriously decreased performance, as evidenced by any number of studies on shift-workers. Assuming you are managing this kind of schedule, you are likely throwing your body's natural cycles all out of whack. What that will cause, I cannot say for certain, but I doubt that it will be good.

I firmly believe that you are entitled to try out whatever experiments on yourself that you wish. But don't try to sell it to others, hiding behind a few misunderstood "scientific" facts. I recommend to anyone that wants to try this out, or any other self-experimentation, to check out the facts before jumping on the bandwagon.

REM Sleep (3.50 / 2) (#92)
by The Solitaire on Mon Apr 15, 2002 at 06:30:36 PM EST

Shoulda posted this with the original, but I didn't think of it right away....

One thing that I really cant understand about this schedule is exactly how the brain is supposed to be "tricked" into going into REM right away. Normally, REM is the last stage of sleep you enter... not the first. It seems prima-facie that this would be a way to deprive yourself of REM sleep, not everything else...

I'm not adverse to the idea that REM could come earlier after severe deprivation, since I am aware that the body uses homeostatic mechanisms to conserve REM. However, if there is any reference to this effect in the literature, I'd love to see it.

by illaqueate on Mon Apr 15, 2002 at 08:25:42 PM EST

from here (pdf):

"The main findings of selective deprivation studies suggest that-

- Deprivation of REM sleep leads to increasingly shorter delays before REM sleep resumes (REM latency).

- A `REM Rebound', or temporary over-shoot in REM activity is typically found.

- Short REM latencies and REM rebound suggest that a `REM Pressure' exists; if so, it is related to the composition of prior sleep rather than prior wakefulness."

Some of the other lectures in that directory answer questions of some of the other readers on this forum.

References... (4.66 / 3) (#136)

Sorry that I didn't post any references, I was at work, and I didn't have a lot of time to spend on my reply. Unfortunately, I don't have any good web references. All of my experience in the field has come from the literature, which is usually not available online. Even though it's not likely to get used, I felt that I should at least post the references for people who want them.

In addition to the particular papers I have posted below, the special issue has a number of excellent papers theorizing not only about the function of sleep in general, but particular stages as well.

The resource that I am most familiar with (and the only one I have in front of me at the moment) is a special issue of Behavioural Brain Research, on the function of sleep. In it there is a study which reports the average survival times of rats when subjected to various types of sleep deprivation. In this sudy, rats were deprived of all sleep, REM sleep, or Non-REM sleep. All three groups died (living 2-3 weeks, 5 weeks, 45 days on average, respectively).[1]

The fact that selective deprivation of NREM sleep is fatal to rats is pretty good evidence that NREM sleep is important, at least to rats.

In the same issue, one research group hypothesises that it is the serial occurance of both REM and SWS (slow-wave sleep) that is important. Particularly, they believe that the sequence of SWS followed by REM is important for memory.[2]

Lastly there is an excellent review of the liturature on the effects of total sleep deprivation in rats (aside from eventual death).[3]

"rats DIE if you sleep deprive them for approx 20 days or so"

I remember hearing of an experiment on this. They placed a rat on disc with a board across it. Whenever its brainwaves indicated the onset of sleep, the disc rotated. This forced the rat in to the board and made it wake up. This rat died two days before it would have starved to death.

by Spatula on Mon Apr 15, 2002 at 07:36:00 PM EST

This is exactly what I wanted to see in response to this article. Nutritional deprivation is nearly synonymous with sleep deprivation. During sleep, the body processes chemicals indtroduced during non-sleep time. These processes are part of the circadian cycle, and, by breaking up the sleep cycle, one can seriously inhibit the induction of essential chemicals to the body.

I can't be hypocritical here, however. I sleep for about 4 hours a night, and that's on the good nights. Usually I'm woken by either street work or very icky violent and bloody dreams. I have noticed a significant loss in both weight and physical stamina as a result (at least somewhat) of truncated sleep times.

My advice? Sleep as long as you can, and hold a very nutritious diet, including greens, fruits and limited amounts of meats, especially meat dishes that are high in cholesterol (I'm talking about Cashew Chicken from your local Chinese resturaunt, or some other simulacrum).

Unnatural? Hmmmm.... (4.00 / 1) (#85)
by bjlhct on Mon Apr 15, 2002 at 05:58:43 PM EST

Well, you can't just claim that this is unnatural and would kill you. Betcha 99% of people reading this have an unnatural sleep cycle. Go without artificial light for a month and you sleep in 2 ~3 hour segments with ~1 hour in between of something like lucid dreaming. I'd like to try that sometime, but you think an employer who lets you take naps is hard to find? Find one without artificial lights! Anyway, this might even be a way to break into a Uberman sleep cycle.

If all you're saying is really really true, then I'd try that too. But I'd like some more people, some people I know to try it first. And, I'd like to know how this turns out. Bring us another story or something in a couple months.

My personal feeling is that you'll be OK, but you gotta not let acid build up in your muscles and manage your insulin and whatnot, as you won't get it free. Be careful man, you could kill yourslef if you're not careful...but don't worry too much: you'd feel like shit for days first. (=

Artificial Light (5.00 / 1) (#88)
by The Solitaire on Mon Apr 15, 2002 at 06:11:56 PM EST

Just curious - could you give me a reference on the fact that people without artificial light sleep the way you say they do? Something about this sounds incredibly fishy.

I agree that you can't use "this is unnatural" as an argument for not trying something like this. However, there is lots of good scientific research being done on the purpose and importance of sleep. Most of that research seems to suggest that this sleep schedule is a bad idea, and potentially dangerous.

My advice is rather than letting "a few friends" try it, and relying on their anecdotal evidence, wait for some serious scientific examination. There are a lot of scientologists out there that were sucked in by anecdotal evidence... they all claim that auditing really works - what makes you think that this is any different?

Because for many years now I take a month every summer and live at a cabin where there is no electricity, and generally no artificial light (beyond a flashlight or two), and I still sleep my standard ~8 hours a day, at the start and at the end of my stay.

Do you actually believe this? (none / 0) (#180)
by theR on Tue Apr 16, 2002 at 02:36:04 PM EST

Why would you? Tell me how the addition of artificial light causes us to sleep for longer periods of time and the absence causes us to sleep in two or three hour shifts. If you go without artificial light, you typically sleep through the night, especially if you work all day. For example, if chimps are any indication, it is completely natural to sleep through the night. I'm sure there must be some information on the web pertaining to people, but I honestly haven't looked.

Artificial light is what makes it possible for far more people to have screwed up sleep patterns, which are ones where people sleep very little or in short intervals. Perhaps the brain does not need much sleep, so that is why so many people here, if you believe the stereotype of most kuro5hin readers, are so interested in things like the Uberman schedule. But I assure you that the body needs sleep, and will take it in one large section of time at night if allowed by the brain. Check with any manual laborers or athletes, and they'll almost always tell you that they sleep for long periods mostly uninterrupted, especially if they wish to perform their best. Naps, if they occur, are usually in addition to sleeping through the night.

Heart Strain on Waking? (4.00 / 2) (#100)
by MUD on Mon Apr 15, 2002 at 07:07:06 PM EST

This immediately made me think of something that I read a while back about siestas being linked to heart attacks. The basic idea being that the heart is placed under a lot of strain immediately after waking and so it might be wise not to increase the number of time that your body has to wake up during a 24 hour period.

I have heard little further on this though, which suggests that it hasn't been borne out by further research. Nor can I think of any way that you could assess whether you would be putting yourself at risk by following an Uberman sleep schedule.

by Dolohov on Mon Apr 15, 2002 at 10:49:57 PM EST

It seems to me that most of the time I wake up from naps, it's in sheer terror (OK, maybe not terror. Mild anxiety, say) that I've slept through something important. I also tend to wake up fairly often to an alarm clock. I suspect that many other people are the same way, and this would probably explain the elevated pressure and heart rate.

Besides, correlation studies don't really convince me all that much. The effects mentioned are interesting, but I find it very hard to believe that such a mechanism would survive millions of years of mammalian evolution.

Still, it's an interesting take on the subject; kudos for bringing it up.

I assume the strain on the heart is caused by it quickly increasing the blood flow (and thus oxygen flow) to most parts of the body. This could well be a benefit for animals living in a predator-rich environment: the difference between sleep-level oxygen levels and full alertness oxygen levels in your muscles could be the difference between life and death.

I'll be impressed if you can keep it up (5.00 / 14) (#112)
by NoBeardPete on Mon Apr 15, 2002 at 07:56:20 PM EST

When I was a sophmore in college, I had a wicked course load, and averaged ~2 hours of sleep per day for about 6 weeks. I had more or less gradually ramped down to that, so the previous month was maybe ~4 hours.

For a while it seemed like I was doing fine. I'd grab a half hour to an hour two or three times per day. I'd go into my morning class early, sit down in the empty lecture hall, and go to sleep at my seat, counting on my friends to wake me up when they go there. Eventually I could just crash on a couch in the student lounge, or even slump over next to my keyboard and expect to wake up on my own within an hour. I was getting a lot of work done, and I wasn't even very tired most of the time. After a while, I even started to feel like I had a lot more energy than I normally did. I figured everything was great.

After a while, though, I started to realize that my extra energy was fairly shallow - if I actually did anything very intensive I would quickly crash. More seriously, I could feel myself becoming more easily frustrated by increasingly smaller things, and generally becoming less well balanced.

By the end, I was really getting hit by the effects. I spend the last few days before turning in my big final project having a great deal of trouble dealing with my friends. Near the very end I started to get back physical side effects, too, including seriously decreased appetite, blury vision, and even the shakes. Fortunately I got the big project turned in before things continued to get worse, and managed to catch up on desperately needed long periods of normal sleep.

Having had many friends who have pushed themselves to great extremes because of coursework and responsibility, I think this is relatively typical. People who get into sleep schedules that involve very small amounts of sleep often manage to adjust quite well for a period of time that can last from a week to maybe as much as a year. But it takes a toll that eventually catches up. People often have an almost manic increase in energy, but usually seem to get worse at dealing with interpersonal problems. When people finally crash, it often seems to lead to at least mild depression that lasts for a while afterwards.

Perhaps you'll be able to keep this up indefinitely. However, I would encourage you to pay close attention to how your mental state may be changing. Do you get agravated at people more easily. Do things that would normally mildy irritate you become very big deals? This can be hard to notice, and takes a little bit of introspection to really be sensitive to this. You say you have more energy, but how much depth is there to that? Keep track of this kind of stuff with time.

It wouldn't suprise me if people are designed to be able to pull this kind of schedule off for limited periods of time, as an adaption to deal with extreme situations. This would certainly be consistent with somewhat increased levels of energy, perhaps even a certain degree of mania. However, it probably isn't something people are designed to be able to sustain indefinitely. However, this seems to come by way of a constant stress and adrenaline.

While having your "fight or flight" response constantly triggered on a low level may enable you to stay alert and awake a lot more, and may be able to get a lot done, it's not really healthy, and will probably catch up with you eventually.

So I would encourage you to pay close attention to how you're holding up. Please write a follow-up story, either when you kick the schedule, or after you've been sticking to it for a few more months, talking about how it's been. Especially if you're passing this off as a "how-to" type of deal, I think it would be good to tell people about how things go after a slightly more extended period of time.

Consistency (5.00 / 1) (#212)
by IoaPetraka on Wed Apr 17, 2002 at 09:14:10 PM EST

I was in a similar situation while I was in college. I had an extremely heavy class load (not quite up to pre-med par, but close) and in addition I was working part time to be able to afford education. I got to the point where I was crashing at midnight and waking up at 4:30 in time for my morning job (my last class got out at 10pm, and I only had a total combined of two hours during the day of free time.)

I started experimenting with alternative sleep methods, as a way to somehow bridge the gap between the obnoxious schedule and the need to sleep. I played with "brainwaves" a method for getting you into deep REMs for an hour, and that worked okay, but I felt like a shell most of the time, getting a total of three hours of honest sleep, and one hour on the brainwaves. I experienced the same sort of effect you had. Initially I had an abundance of energy, and thought maybe this brainwave thing really was great. Over the space of a year though, that changed and I started turning 'hollow.'

After college, my body had essentially become used to this sort of treatement. Even though I had the luxury of sleeping as long as I wanted, I typically would awake three to four hours after falling asleep. The only difference was that I gradually lost the "shell-like" feeling, and eventually lost it altogether. For several years I was able to sustain this sort of sleeping rate with no adverse side-effects.

I would suggest that the main reason you found no luck in catching parcels of sleep throughout the day boils down to one simple word: consistency. The outlined method described in this article gives a very strict schedule on when to sleep and when not to sleep (thus making it useless for people in some careers.) On the other hand, your adopted method sounds as if it was a bit erratic.

Even if you are getting a full eight hours of sleep a night, but you take those eight hours at all different times of the day, you will feel the effects of sleep deprivation. Consistency is almost, if in fact not more, important than how long you sleep.

Consistency worked for me, because even though I was only getting four hours of sleep, I was taking those hours at the precisely same time during the 24 hour day, week or weekend.

Also, I never could sleep sitting up, only laying down. This is not something related to caf. or to not working out, etc. Not sure where it comes from.

I don't think it would be possible at my work anyway. I suspect this is true for most people. The office is just bad for this type of sleep pattern.

Seems people jumped on my case about my earlier comment to this article. I find that odd considering most of the other "I" (or "me" related, some people have a problem with the word personal) related stories I've seen in the past couple days were dropped into oblivion. In fact, i can't remember the last time I say an "I" story make the front page. It sure as heck is in the minority. There was a famous person who once said:

those accused of misogyny, for the most part, are those who say what other people are thinking, but don't have the guts to say

I dare not call myself a misogynist, but i stand by my earlier statement.

by valeko on Mon Apr 15, 2002 at 09:18:23 PM EST

It seems that a lot of this relies on the ability go to asleep immedaitely, which I do not have, even in the most tired physiological state. It takes me around 30 minutes to an hour to actually fall asleep, almost regardless of how tired I am. Of course, it will happen that if I go sleep deprived for 4 or 5 days, I will occasionally just crash and fall asleep immediately and sleep for the next 14 hours, but generally it doesn't work.

by BigZaphod on Mon Apr 15, 2002 at 09:32:46 PM EST

I've been having a sleep problem. Maybe someone out there has run into it and found it going away or solved it or whatever.

Anyway, the basics are that I seem to have a natural sleep schedule of about 4:00am to 12:00pm or so. As you can imagine, this doesn't work with a normal job at all. However, this is the sleep pattern I fall into on the weekends and when I don't have to get up in the mornings (holidays, etc).

I'm in me senior year and only have 2 classes to go to each week. So, I work a lot and will be working full time in about 4 weeks time. My boss is currently simply "putting up" with my erratic behavior for now, but I have a feeling he won't stand for it when I'm full time (even if I do work a full 40 hours per week, he wants me there when everyone else is because we're going to start doing pair programming (as in XP) and it only makes sense, so I can't argue that logic).

So, anyway, I can never seem to get to sleep for the length of time I need it (pretty much a full 8 hours) because I can't fall asleep right away. As a result, I constantly get woke up in the middle of REM and am tired all day. Usually making stupid mistakes, not thinking clearly, etc. All day. So, not only do I have a hard time making it to work on time, I suck while I'm there!

I just can't seem to change this, either. I've tried, but it never works. It is only made harder by the fact that my friends often do things late at night (which is perfectly comfortable and natural for me). In typical fashion, I seem to be the only one who can't go to bed at midnight or so and still get up at 8:00am the next morning feeling good and refreshed. I *should* be able to, but I can't sleep soundly right off the bat and so always wake in REM feeling like crap.

Has anyone else had this sort of thing happen? Why can't my sleep pattern just settle down into something more normal/usable? *sigh*

I had/have the same problem. (4.85 / 7) (#126)
by Cal Bunny on Mon Apr 15, 2002 at 10:21:14 PM EST

This is the same type of insomnia that I have. This could just be short-term problem, especially if you are feeling stressed or excited lately from your position in life. There are a couple of things that you can do (I cannot seem to find a good link so I will run them down for you myself):
  • Establish a regular bedtime and wake-up time and stick to them. This regular sleep-wake schedule trains you body to become tired at the end of the day and become alert in the morning. If you are eratic your body will never develop this habbit.
  • Avoid taking naps, especially in the afternoon.
  • Exercise regularly during the day. Preferably in the morning and never at night. First, this will tire you to allow you to go to sleep later. Second, it will raise your body tempature which is a signal for your body to wake up. Before you go to sleep your body tempature begins to drop. If you excercise too late your body will not cool as it should.
  • Keep light levels very low after sunset and keep the bedroom very dark. This helps me tremendously. The sunrise and sunset resets our internal clock; that circadian rythm and stuff.
  • Use the bed only for sleep and sex, not for reading or watching television. If you cannot sleep after about 30 minutes then leave it (but still wake up at your normal time the next morning). You train your body by example. If you use the bedroom as a workroom then your body will become more alert and attentive when you enter. It will not learn that the bedroom is for sleeping (and sex, woot!).
  • Avoid caffeine, other stimulants, cigarettes, and alcohol. If you smoke, try to quit smoking entirely. Cutting back on smoking without quitting may lead to nicotine withdrawal in the middle of the night that awakens you. I used to know a friend that woke up with caffein and then used to drink some alcohol to help put him to sleep. This destroyed his internal body clock. Also, alcohol will often prevent you from sleeping very well well even though it may relax you slightly.
  • Try to reduce stress in your life by changing those things causing the stress. Easier said than done, I know. Some people suggest reading something light or entertaining just before you go to bed, to get your mind off the day's troubles.
  • Some people say to Consider using white noise, such as a fan blowing, but I find that I sleep best with absolute silence. Some people say ear plugs and an eye mask can help. They are better than noise, but don't feel comfortable when sleeping to me.
  • My personal favorite advise is to sleep with somebody else. Sleeping with my ex-girlfriend used to help tremendously. I used to fall asleep almost immediately when I put my arms around her. I slept very still that way, too, waking up with my arms still around her the next morning. Of course you have to be with a person that enjoys that as some people cannot stand to sleep in such close proximity to somebody else.
There is a relatively new prescription sleep medication called Sonata (zaleplon). I wouldn't give this up for anything right now. It is unlike all other sleeping pills. It basically has a really short half-life and only works for a couple of hours, but it hit very hard. The first time I took it I had minor hallucinations. As a result of the short time it exists in your body you only need 4 hours of down time after taking it (most sleep medications require 8). It helps most to fall asleep, but you happen to wake up in the middle of the night and you have at least 4 more hours until your wake-up time, then take another. They say that is the first really succesful sleep medication that you can take on an as needed basis. They cost about $2 per pill. I love them.

by Go5 on Tue Apr 16, 2002 at 01:16:10 AM EST

I used to have the same problem. My doctor made many similar recommendations, most of which worked well.

A few remarks:

  • Sex is a great sleep aid. For a great night's sleep, try an evening session starting a little earlier than usual.
  • The advice about exercise is right-on. If possible, consider several short exercise sessions throughout the day. For example, run a couple miles early, lift weights for 15 minutes before lunch, then bike for an hour in the evening. Unless you're trying to lose weight or body-build, two or three 20-30 minute sessions work fine.
  • Be sure your bedding is in decent shape. Better pillows made a huge difference for me.
  • I've found reading before bedtime to be counter-productive in the long run. My body's been accidentally trained to become sleepy after reading for more than ten minutes or so. Oops.

    It could be that you are simply in that cycle due to doing activities late at night - your sleep cycle can start to "rotate" around the clock when you do this. Maybe the activity is something that stimulates your body more than your friends, making it harder for you to sleep straight away. One thing I do that often works, when this happens, is to force myself to stay awake all night, and then go to bed at the proper time the next night. I didn't sleep at all on Sunday night, and slept a beautiful 10.5 hours last night!! (from 9pm)
    Another trick I have heard of is to go to sleep an hour later than usual, and move your sleep time an hour or two back each night, until it has rotated right around to the time you want to go to sleep. Obviously you will need a long period of not needing to go to classes or work to do this. I haven't tried this technique, though.

    by Fantastic Lad on Tue Apr 16, 2002 at 09:06:50 AM EST

    I work at home, and I keep whatever hours I want.

    Like you, I'm irregularly up late with friends and/or work. Basically, the nature and intensity of my social and cerebral activities determines when I sleep. I think perhaps the invention of the light bulb might have something to do with this.

    I wonder if perhaps animals which are on a habitually determined sleep schedule do better and feel better, sleeping because the sun goes down rather than when they run their batteries dry and collapse from exhaustion, which tends to be my way of going about the whole affair.

    I don't think this causes a problem. I usually feel pretty darn good, although I do typically sleep more than the recommended 7-9 hours a day. I generally sleep a minimum of 10 or 11. I always wake up feeling rested, (unless, of course, I've been dead-line chasing and staying up past when I feel tired, drinking coffee and such.)

    In any case, it sounds to me as though you are going to have to make a choice in how you live; do you want to live a life pursuing regimented goals determined by somebody else, or a free style kind of life like the one it sounds like you currently do. --Both work, although I find the thought that most of the first world population goes through early morning hell 5 days a week entirely monsterous! I refuse to get out of bed until I feel bored with being horizontal! --It's the only way to live; I look years younger than anybody else my age, and I generally attribute this fact to my sleep and work habits, (although, eating well while not drinking or smoking might have something to do with this. --Except those kinds of behaviors, I feel, are directly linked to how miserable your job makes you).

    You might think about trying VERY hard to figure out and implement an alternative life-style which will allow you freedom from the 8-5 work week.

    It's not easy, and it's different for everybody, but it IS possible.

    Interestingly, after working for myself for over a year, and not having to set an alarm, I've gotten so no matter when I go to bed, I almost always sleep for exactly 8 hours. The time I go to sleep varies from day to day, depending on a lot of things, but the 8 hours is invariant.

    I did this about two summers ago, saying good night to my father at 5:00 in the morning and sleeping in until about 12. They got concerned and (my mom is a phycologist) they showed me the studies that said that reversing your sleep schedual is detrimental. So since you don't need any convincing that this is bad and you want to go back to a normal schedual I will tell you my secret to adjusting one's sleep schedual: lots of bud and caffiene. Okay so maybe this is an artificial way to do it but hey, it's easier and (if your used to bud and coffee) feels better. So now either smoke some heavy indica and fall right to sleep or if you have sativa (or maybe you want to enjoy your high) smoke it 2 hours ahead of your target bed time. I have fallen aseep for 18 hours before on bud so make sure you have your alarm clock on loud, a friend to make sure your up, and a coffee maker that will brew some coffee automatically as you may be very groggy.

    by opendna on Tue Apr 16, 2002 at 12:07:36 PM EST

    Anytime I find myself slipping into the 4-to-noon sleep pattern I skip one sleep cycle and set the time for the beginning of the next one. I won't go to bed at 4 am and will force myself to wait until 9pm. I avoid all drugs for the last 4 hours (especially stimulants) and exercise to stay awake. Usually by the time the target sleep time comes around my body isn't very particular.

    There! I'm on the schedule I want. This doesn't mean I can't/won't slowly revert back to the 4-to-noon schedule; it takes some discipline. Others in this thread have written great advice about getting to sleep on schedule (e.g. exercise, drugs, sex, etc.).

    Usually I have a different sleep schedule on the weekends, and switch for the weekdays. I had a terrible time adjusting, some weeks I was like a zombie. I finally ended up not sleeping saturday night and sunday morning. I would deal with it by avoiding caffeine and sugars and eating a lot of protein. I would make it through sunday pretty easily (if you do the high protein thing you will avoid the stupidity that comes with lack of sleep) and fall fast asleep at ten on sunday night. The next morning I wake up nice and early at 6:30 AM. I have never encountered the so called "sleep defecit".

    I find that, for me, a 4am to 10am schedule is best. After sleeping those six hours I feel good, happy and ready to go. Unfortunately, like the others here, this is not very conducive to long term employment. The problem is that it seems to require two hours extra sleep at the beginning of the night in order to wake up one hour earlier. All week I sleep from 10:30pm'ish to 7:30, 9 hours, and wake up and go to work feeling like I was robbed of about four hours of sleep, only once I get some crack-a-cola into my system are these effects mitigated. And yet, once Friday comes around again I stay up until about three or four and then wake up at around ten in the morning, feeling refreshed, happy and ready to go. It is annoying and confusing. On top of this, in almost all cases the hours between 8pm and 2am are by far the most intellectually productive of my day, that is, as long as I am not sleeping during them. It is all so stupid!

If left completely without any pressing needs, I'll continue to turn the sleeping time all the way around until I wake where I started after 3.5 weeks.

    I usually have a friend call me in the morning. I wont wake up just for the alarm clock to get to work, unless there's a meeting or something with overriding priority that I know affects someone else but me. But someone calling works since it _might_ be someone else with something important.

    the first being that this is a side effect of a whole bunch of hormonal changes starting with adolescence and progressing into one's mid-twenties. It definitely seems to be more pronounced for men than for women, and I've actually read some fairly large studies that corroborate the same timeframes for sleep. In other words, this is perfectly normal (and the number of people posting similar issues suggests that it's certainly typical of k5ers!). The other interesting thing relates to a couple of long-term studies regarding light stimuli and other biological "internal clock" issues. These studies were performed in caves or laboratory settings in which no sunlight or other outside factors were allowed in, and the participants regulated their own light sources and sleep patterns; people slept when they were tired, and were awake when they felt like being awake. Within a month, all of the participants were on a 30-hour day. Kinda funky when you think about it. As far as fixing it, well, everyone else here has given the same advice that I would.

    I know that this sleep pattern is definitely not for me. I get rather irritable and cranky if I don't get eight to nine hours every night. I've found, however, that years of working in the real world can do wonders for changing your schedule. In college, I avoided 8AM and 9AM classes like the plague, but now, sleeping until 7:30 is "sleeping in" for me!

    But this article did remind me of something strange in my life. I took a trip to Japan for my job last year. It was hard enough to get used to time over there - I would get up with the sunrise at about 4:30AM, because that's what I do here. By 8PM, I was really tired, but I was drinking so much I didn't care.

    But even stranger was what happened when I came back- I came back on a Saturday, and had the weekend to recover from the trip and from work. With nothing that important to do, I lapsed into a similar sleep pattern to the one discussed here for a few days (I think it was that after three hours awake, my body turned itself off for an hour wherever I happened to be.) This didn't happen in Japan because we kept ourselves so busy during the day and so drunk at night...

    Could it be that this is the state our bodies return to when we're not strict about what time we need to do things?

    the need for sleep (4.00 / 1) (#141)
    by tiger on Tue Apr 16, 2002 at 12:44:03 AM EST

    The reason why we sleep is an open question. Probably most people guess that sleep does something restorative, such as the body doing repair work, or building up chemical reserves, or something like that.

    My own view, which I arrived at a few years ago, is that sleep is a time during which reprogramming can take place.

    Most people probably do not realize how universal sleep is throughout the animal kingdom. For example, insects sleep. I have written about what I understand sleep to be, in The Need for Sleep. The context assumes that our cells are, in effect, under programmatic control.

    My wn view, which I arrived at a few years ago, is that sleep is a time during which reprogramming can take place.
    This is actually not an unfounded view. I read a paper some time ago which theorized that the function of REM sleep was to prevent overtraining in the human neural network. One way to do this is to wash random noise over the network. It turns out that there is a wave of ectivation in the human brain called a PGO (Ponto-geniculo-occipital) wave that occurs during REM sleep. They refer to this effect as "reverse learning".

    There is some information on overtraining in artificial neural networks here.

    I checked out your criticism of artificial neural networks, but it seems to me to be resting on what I believe is a flawed understanding of memory. That is, that memories are in some sense a "thing". In my opinion, this is not a warranted view - memories are more accurately understood as a process. For an interesting read on the nature of mind, check out the work on dynamical systems theory by Timothy Van Gelder.

    what you call re-programming is the REM sleep phase. It's not a single-cell process but the re-organization of neural networks.
    Did you know that babies do a lot more REM sleep than adults of any given animal species? Did you also know that while climbing the evolution tree, animals do a lot more REM than their ancestors (ie. primates do more REM than birds)? Some (rare) animals do not actually "sleep" like sharks but the latter have been prooven to "swap" one hemisphere at the time in REM (they cannot "sleep" since their respiratory system stops working if not moving). Experiments on volunteers have proven that REM deprivation negatively infuences attention and intellectual skills in an impressive manner.

    Physically, anyway.

    I wonder if the REM portion of sleep is necessary for mental health, the rest of the sleep cycle may be a mechanism for the body to repair bruises and cuts, etc.

    Is anyone out there on this sleep schedule that generally abuse their bodies (I am not sure what profession this might fall under - construction comes to mind) that feel their physical bodies still seem to repair themselves as quickly as giving them 8 hours sleep?

    Buckminster Fuller did this (4.50 / 2) (#152)
    by Jonathan Walther on Tue Apr 16, 2002 at 03:42:19 AM EST

    I don't know when Uberman developed the technique, but I read in Bucky Works: Buckminster Fullers Ideas for Today, by J. Baldwin that Bucky had developed this technique in the 1940s. According to Mr. Baldwin, Bucky followed this regimen for 2 years, gave it up for reasons unknown, although it was implied that he stopped to please his wife. Despite giving up this particular sleep schedule, Bucky was noted throughout his life for his perpetual level of energy and the long hours of work he would put in, with little sleep. Mr Baldwin was upset that the authors of the "Power Napping" concept didn't credit Bucky for being first.

    sleep accumulates (none / 0) (#178)
    by Rainy on Tue Apr 16, 2002 at 01:21:53 PM EST

    I read in some research papers or articles that sleep accumulates over a very long period, a year or even a few years. In other words, if you cut down on sleep during one year, the next one you'll have to generally sleep longer or you'll have negative health effects.

    By the way I remember reading recently here that Salvator Dali had a habit of taking cat naps - where he'd hold a spoon or a fork above a metal surface and go to sleep. As soon as he'd enter a phase where muscles relax, he'd get waken up by the noise.

    Actually, sleep DOES NOT accumulate. According to recent studies, if a person gets normal 8 hours of sleep, then down to 3 hours, sleeping for 13 hours will not catch that person up on sleep. It doesn't accumulate.
    Don't take my word for it, it was in my psychology textbook.

    I came up with:

    cnn article where Dr. William Dement, a noted sleep authority at Stanford University, says: "You lose a half an hour a night over the course of a month, and this will slowly pile up... As far as we know, all lost sleep accumulates as a debt."

    Well, there's at least a full page of hits, I don't want to paste them all so help yourself.

    On the other hand I have to say I never studied dissenting opinions or researched this matter in detail, I think an article in new scientist or something like that caught my eye, besides that's been my personal observation, too. There's certain amortization here, that is, if I sleep 3 hours on one night, the next I can sleep for 9 hours and feel okay, but if I sleep for 3 hours on several nights, then I have to sleep much longer also for several nights.

    I can vouch for that (none / 0) (#205)
    by CAIMLAS on Wed Apr 17, 2002 at 02:27:42 PM EST

    Last year in college, I slept roughly 1 or 2 hours a night, and maybe once a week, I'd sleep for 10-14 hours - generally Friday late-PM (or Saturday early-AM) into Saturday evening. I was always tired, and never seemed to get the sleep I needed. (I was battling with some heavy depression/chemical imbalances, insomnia, stressful situations, and relationship problems at the time.) This is essentially the same schedule I had my last year of high school, 2 years ago.

    This past summer, I slept a very large amount, and I am finding this year that I require a larger amount of sleep this year in school than I did last (this is my sophmore year). I also find that I'm much more ill this year than last - I was always healthy last year, but this year I seem to be constantly battling illness.

    As far as the power-nap, polyphasic sleep schedule is concerned, I've heard and read that it is generally bad for your body as a whole, despite the possible energetic feelings that you experience. The first 2 states of sleep are for physical healing and regeneration, while the second two are for mental relaxation and 'resequencing' - the 5th stage, REM, is for mental and physical regeneration/energization. By only having REM, your body loses out on a lot of body-produced horemones and other chemicals that keep your system running optimially. Our bodies are biofeedback systems - we're designed (or evolved, whatever you prefer) so that we can only take a certain amount of input before it becomes hazardous to us. Asside from the stress on your body from being up and running for 21 hours of the day, there is also the lack of maintanance being done during sleep. Thus, in theory, you will age more quickly, and likely die early. (This is the explaination I've read in various places.) I've heard that people that sleep more or less than the prescribed 8 hours a day tend to live shorter lives than those that sleep a solid 8 hours.

    On the other hand, I've also read that the less people sleep, the longer they live - I'm not sure which one is correct, or which factors the two studies took into consideration.

    Everyone with kids does this (4.00 / 1) (#183)
    by pkesel on Tue Apr 16, 2002 at 05:01:08 PM EST

    Anyone who has experienced the first few months with a new baby, especially more than one, has done this. Especially those with a child that has sleep or eating problems. You learn to survive on an hour or so of sleep whenever you might get it. You often find after a while that you can't sleep more than that. It's remarkably frustrating.

    My own experience (4.00 / 1) (#185)
    by everyplace on Tue Apr 16, 2002 at 06:26:12 PM EST

    In february I started working at a gas station (long story). Prior to working there, I had a normal sleep schedule, around 8 hours a night. But as soon as I started at the gas station, I was working the 11 pm to 7 am shift, and my sleep schedule was thrown into chaos.

    The hardest part of adjusting was figuring out when I was supposed to behave as a normal person. Do I get up around 5 pm and work on my own stuff then, and go to work afterwards? Do I get up right before work and stay up until 2 pm?

    What I ended up doing was forgetting any normal concept of sleep schedule, and opting for as little sleep as possible. These days, I get up at 10 pm, just enough time to get to work, and stay up until around 7 pm, which gives me an incredible ammount of time to do things.

    Now, since as I said this is at a gas station in the middle of the night, things get really slow sometimes. There's a really loud bell on the front door to the place, so sometimes I sit down and power-nap for maybe 10 minutes, until someone comes in, and then I'm up and waiting on them. So I suppose this is cheating a little bit, but regardless.

    When I get home from work, I'm up and doing things all day. My two roommates are awake at this time, so we can get our daily dose of interaction out of the way before they go to work. I can do my daily web routine, do some of my own creative work, and even fit in some house chores before sleeping again at around 7 pm for a few hours.

    I'm not recommending this sleep schedule under any circumstances, I'm just throwing it out there for the record of diversity.

    Looks ok to me! (4.25 / 4) (#191)
    by KiTaSuMbA on Tue Apr 16, 2002 at 11:24:25 PM EST

    Some points I'd like to underline:
    Sleep is not a prescribed drug... you should get as much as you feel in need of. Thus, if you wake up and feel rested and fresh, go on with it, if not, go back to normal day-night cycles.
    On the benefits, you should add the actual full REM sleep benefit: your memory and intellect is based on REM (yes, most work is done in sleep not awake, however strange this sounds). While working on mentally-heavy projects such a sleep cycle will help you cope better than usual day-night cycles. The fact is that you re-elaborate (in REM) your project chunk by chunk in each nap. I used a similar scheme, though not knowing there was a scientific description and kind of automatically turned myself in it, while studying Anatomy for the exam in Univ. I had a 15 days time for say, 2000 pages of Human Anatomy. I used to study a chapter then take a nap (30min - 1hr max) then back to the next one, resulting in a study time of 18hrs/day without ever feeling tired. It actually worked out with the best results but the drawback was I had to postpone the vacations a week after the exam because I couldn't get enough of my "just doing nothing" afterwards. Another scheme I tend (still not designing things, it just happens) to fall into is the so-called bi-circadian cycle (2 days, 1 night sleeping) while working in stressing projects. These periods last for about 2-3 weeks and I don't feel tired ever (not even afterwards). While not so fruitful for intense-thinking jobs this scheme works great for projects needing just a lot of work (e.g. designing an experiment is intense, going through statistics after semi-automated R scripts is not but takes lots of time). The rest of the time I practically have NO wake-sleep schedule whatsoever. Days pass I sleep 4 hrs and feel fine, days pass that I sleep 12 hrs and feel like a tank roamed over me, night or day, never minds.
    Your larger appetite is by no means a drawback (unless you can't pay for filling that fridge every day :-P). You are awake 21/24 and even when asleep you are mostly on REM (thus thrusting your brains at warp 9 ;-) : energetical needs thus are expected to be higher. Orange juice and the like provide you with vitamin C which is an "anti-oxidant" helping your body while in physical stress (that is why orange juice is the best "medicine" against flu, as your grandmother told you).
    The point of INTENSE, vivid dreams is the actual proof this works for you: pure REM activity. Another piece of personal experience: whenever studied *seriously* an exam, I would always dream about the contents of the exam the days before it. I remember writing down the formulas in Biochemistry I without even reasoning, I just remembered the dream, heh.
    WHAT TO WATCH OUT FOR:
    1) A stronger tendency to occasional illness (like colds and the like). More hours awake means more stress for your body.
    2) Taking up weight. Your increased appetite might induce you in eating up just about everything. Strict food schedules may help.
    3) If you are required to handle heavy/complex equipment (like a bulldozer?) you better leave this sleep schedule behind. These rapid sleepyness attacks can cost serious damage if not victims if they occur while at work.
    4) restlessness: if you find out you are becoming "jumpy" in your social relationships, it would be a pure sign you are pushing your mind too much. Either relax, or abolish this scheme.
    IMO, if none of the above happens, there is nothing to worry about. What seems to be the hardest part of it, is the adjustment period, as you already pointed out.

    Your grape juice (4.50 / 2) (#198)
    by Wulf on Wed Apr 17, 2002 at 03:14:20 AM EST

    This really had me interested all day, especially because of my screwed up sleeping periods. Thanks to watchmaker for the term "polyphasic sleep". Claudio Stampi and his Chronobiology Institute has done a lot of research on this, though I couldn't find much online. He has a book called "Why we nap". I remember first hearing about him and polyphasic sleep on the Dateline special of Ellen MacArthur (She used polyphasic sleep while sailing around the Antarctic alone).

    As for your grape juice addiction, I believe it has to do with the content of Alanine, though it's not much (around .208g per serving). Alanine is used in the metabolism of Tryptophan, an important neurotransmitter.
    Something else that would worry me about missing out on NonREM sleep is your bodies production of Melatonin, described as the "time setting hormone", the production of GH, and Serotonin. Also, the already mentioned increased production of Cortisol.

    I would recommend that you take a full vitamin supplement, like Centrum and a drug called Ademetionine (don't know commercial name). Adementionine is an excellent antioxidant, helps your liver work well (production of serotonin) and works as a mild antidepressant. I will be trying polyphasic sleep when summer starts and I will keep a detailed journal. I hope I can also take some medical tests while I'm in the middle of it. Good luck and keep us posted.

    Very interesting. My sleeping habits are somewhat strange. I have been battling cronic depression for over 10 years,so that may have something to do with it. Very often I have problem going to sleep, and problem getting up. My mind is in high gear when I go to sleep, and I feel restless and urge to do something. Watching Discovery or BBC Learning can help, but I find movies boring and uninteresting. I sometimes don't fall asleep until 4, even though I have gotten up at 8. I would love to take 20 min. powernap, when I have the chance I feel very energetic and and productive. But that 3 week adjustment time sounds like pure torture. J.

    A couple questions I might ask:

  • What are the effects of physical activity, compared to a normal 8-hour sleep schedule?
  • If/When you become physically injured, how does the heal time correlate to that of an 8-hour sleep schedule?
  • Have you noticed any changes in your physical appearance,tactility feeling? Skin, weight, muscles, joints, shakes/shaking, unsteadyness, blurry vision, tension, etc?
  • Is your energy level perpetually high, or does it come in bursts, and burn out quickly?
  • Are you truely more functional throughout the day, or do you simply have more time?
  • Have you noticed any changes in your mentality: the way you relate to others, your emotional state, or your thought process?

    I feel that, if this type of thing can be pulled off without physical or mental ailment, it could be an incredible thing for society, provided the long-term effects are not disasterous (IE, shorter life span, or aging more quickly). In our 24/7 society, this could be greatly beneficial.

    It'd be interesting to see how this contrasts with how things are done today in the world and the Biblical way of doing sleep (most likely working your ass off all of daylight hours and some/a large part of the night (possibly spent in social activities), and then sleeping for a large part of the Sabath - a technique I've attempted myself).

    I find myself being more physically active than before; I usually take a run before my 2 AM sleep period, something I didn't do before.

    I have not yet become significantly injured since I switched. I haven't noticed a difference in the healing time of minor cuts and bruises, though.

    I feel in better shape, but this may be due to the increased physical exercise that I am getting.

    My energy level feels like a compressed day during each 3 1/2 period of wakefulness. I usually start off feeling energetic, but by about the two and a half hour mark, my energy level begins to slip. By the time I should nap next, I am usually sleepy.

    My personality seems not very different to me. My significant other says I seem happier and more outgoing; I think part of that could be due to the fact that I'm happy because I'm getting so many interesting things done. For instance, I've been reading Knuth's "The Art of Computer Programming," which is something that I wouldn't have had the time to properly devote my attention to, but now I have plenty of time. In addition, I've written a novel and a half (actually, the last third of a novel, a complete novel, and the beginnings of another) in the past month and a half.

    by sserendipity on Fri May 24, 2002 at 05:45:48 PM EST

    I'm trying a longer, more mellow route to a reduced sleep schedule.

    I've started out by taking the naps >first<, practicing to expect a 'rest' every four hours or so, before eliminating the nightly sleep period. This way, I don't have to become insanely tired, and have to show ridiculous amounts of will power to get out of bed at any time (which I couldn't do :>)

    (It goes without saying that I'd already quit all sleep interupting chemical intake - no more booze, weed or caffeine; I never smoked tobacco. I also started taking vitamins - a multi, plus Niacin, Vitamin C, and B complex)

    Every four hours, I take a 20 minutes to nap; about 10 minutes actually asleep. (At some point I'm going to take a good half hour for this, something I wish I been doing from the beginning) If you are remotely tired as it is, this won't be nearly as hard as it sounds - I actually find it much easier to fall asleep like this than used to do at each night (I used to spend hours trying to sleep each night). I've got myself down from 9 hours of fitful sleep each day to a very restful 6, including four naps.

    I've never felt better, though unfortunately, the lifestyle I'm seeking will require reducing my sleep even further.

    I wake up without an alarm clock, though I'm not getting much more than about 5-10 minutes of REM sleep at this point. I think that will come in the next step, when I start getting less sleep each night.

    I've been on this for a month now, with a couple of days backsliding to a full 10+ hours of sleep, which I expected to happen. Getting back to where I was sleeping at each nap took two or three of days each time. When I miss my nap, I already >miss<it - I feel about as groggy as I used to every day before I tried this system. Could it be that some people are better off sleeping like this? <P> Next, I'm going try waking up in the middle of the night each night, doing a few things (a few minutes music practice) before going back to sleep, and also waking up earlier and earlier in the morning.

    Doesn't this make a little more sense than the 'suicide' method that most people have used? It's also a lot more practical for those of us that have jobs (like myself), and aren't just crazy college students playing games with their body for a lark.

    Sure, it remains to be seen whether it works or not, but I would imagine that it will be a great deal easier to 'make the jump' now that I can happily nap every four hours, and have already cut back my daily sleep amount considerably.
