REM sleep isn't the only important part.
You also need Delta wave sleep to rest and rebuild your muscles.
REM sleep is for your brain. I suppose if you have a very unactive lifestyle this techique might work.
But Delta Wave sleep is very deep sleep, and if you are in Delta sleep it's very difficult to wake you up from it before your muscles are finished resting themselves. I'm quite sure it takes longer than 20 minutes as well.
If you are just going for a brain refresher though it's an interesting idea.

After our daughter was born, I wasn't able to sleep for more than 2hrs straight for weeks on end. Even now it's almost never more than 5hrs uninterupted. I can say that I miss my 8hrs of sleep and don't feel more rested getting 20min naps every few hours.
You're right! 6+ hours is necessary for your body. I'm gonna try taking 30 minute naps during my lunch break.
I'm skeptical of this...so I'm hoping someone daring (or stupid) enough to try this for real and get back to us.
Well, according to the article i've read, 20 minutes is the optimal time for sleep. The key is that the first two weeks you will not believe it's working because it WON'T. Your body has to become used to falling asleep every 4 hours and pretty much "on command." So the first two weeks you'll lie down and just when you start to fall asleep, your 20 minutes will be up. Incredibly frustrating, i've heard. You'll be a walking zomebie for a few days because you haven't had sleep.
But after about 2 weeks your body will get used to your new routine and will fall asleep for 20 minutes every 4 hours. It goes on to say that anything much more than 20 minutes or less....or skipping a nap altogether....can be distastrous. I guess the key is to deprive your body of sleep until it gets used to the cycle of 4 hour intervals. Its supposed to be pretty popular with the college crowd. Personally, i know that i dont have the sleep discipline to wake up in 20 minutes. I'll never make it through those first two weeks because I'll sleep thru at least some of the naps.

Everything living thing on earth is set to a biological clock of 24 hours(aka the circadian rhythm)
It is possible to change the rhythm, but completely getting rid of it is not possible.
Well, I think you have your cause and effect a little turned-around.
I don't believe that Ben Franklin, Einstein, or anyone else for that matter, "used" this technique as though it were some sort of intended plan. More likely, some brilliant people are "driven" to resist sleep and they nap only because they become too damned tired to stay awake. This certainly describe's the reason Thomas Edison was a persistent napper.
These same types of people have also been known to forego personal hygiene or leaving the confines of their work for weeks at a time. I don't think anyone advocates the merits of not bathing for two weeks.
IOW, they don't forego sleep in order to be brilliant, nor are they brilliant because they forego sleep. Poor sleep hygiene is a consequence or by-product of their brilliance, and probably not a healthy consequence at that. The fact that they acheived great things is not a testimony to the benefits of sleep deprivation, it is a testimony to how brilliant they were. They probably could have been even more brilliant or productive had they gotten enough sleep!
As far as the link to 'Mental Rejuvenation In 20-Minute Naps' page: A. this comes from a website advocating all sorts of 'alternative' health advice that is of questionable efficacy. B. nowhere does it recommend or even suggest totally 'replacing' conventional sleep with a system of short naps.
Actualy, about 10 minutes after I woke up from my nap I started to feel alot better. Before the nap I was begining to crash(I slept a bit more than an hour last night) now I feel great.
I might have to start taking naps after school

TCSenter, i appreciate your criticism of my post in the realms of causality, but I think it's fairly safe to say that
1) we are not discussing cause-effect relationships, and
2) the semantics of my wording are inconsequential to our discussion. As inconsequential, say, as me point out that "This certainly describe's the reason" displays improper usage of an apostrophe.
I believe we all understand that all of these famous minds didn't INTENTIONALLY formulate a master plan to sleep exactly 20 minutes every 4 hours. My point is that these types of sleep techniques has been used before.
Forgive me if i sound antagonistic-- that is not my intention.

When I am a millionaire I'll try it. And what to do with your extra time? Surf the net 22 hours a day instead of 16?
so what happens if you're REALLY busy one day.. and you end up staying awake from 8am-10pm...
would you have only slept 2 hrs. that day and the next day your sleep schedule's fked up and you sleep for like 3 hrs. instead of your 20 min.. and then..?

Not impossible, but unusual. People who are acutely or chronically deprived of sleep can have abnormally short REM onset latencies similar to those with narcolepsy, which is why sleep apnea and other potential sleep disorders are first to be ruled out, before a diagnosis of narcolepsy will be entertained.
Ok, maybe I wasn't clear, my bad. Let me clarify: There is no nap "technique" in the sense you have suggested to replace 'conventional' block sleep, it doesn't exist. Many studies have been done, nobody has studied sleep deprivation more than the military, and not a single one has shown this can work. In fact, the overwhelming body of research has shown or suggests the opposite, that it can be detrimental (read: disasterous).
Einstein slept as long as 11 hours at a time and took short naps during the day. Napoleon Bonaparte was a life-long insomniac and took naps because he was sleep deprived. Thomas Edison rejected the practice of sleeping more than a few hours per day. Flippant about its biologic necessity and driven to near obsession with his work, Edison thought that sleeping more than a few hours was a "waste of time". Edison was also notorious for falling asleep every where, all the time, because he was so sleep deprived. Again, it is a testament to how brilliant Edison was that he was able to accomplish a thing, not a testament to the benefits of sleep deprivation. Edison would likely have been more productive had he gotten more sleep!
Let me repeat: these are not "techniques". These are brilliant people who accomplished great things, not because they had sleep disorders or unusual sleep habits, but IN SPITE OF having sleep disorders or unusual sleep habits.
About Leonardo Da Vinci... (taken from Famous Sleepers):
What you've stumbled upon is an incredibly simplistic correlation and nothing more. Many not-very-brilliant people have difficulty sleeping at night and, therefore, are forced to take naps during the day, too. And so while you cite a few stories of successful people who have had sleep disorders or unusual sleep habits, what you have neglected to consider are the stories of thousands of others for whom sleep deprivation has resulted in disaster.
Based on what we know of the science of sleep today, Edison and others were in all likelihood FALLING WELL SHORT OF THEIR POTENTIAL due to being chronically sleep deprived. And so while we see how seemingly well these famous people got by without sleep, what we do not know is whether or to what extent abnormal sleep habits and sleep deprivation were actually detrimental to their productivity and brilliance.
On Edit: The ONLY type of 'napping' that you will find being advocated or condoned by recognized authorities in the areas of sleep science and research are the mid-day 'refresher' naps, but NONE advocate this in place of regular sleep. It is unanimous among sleep science authorities that regular 'block' sleep is ESSENTIAL and nothing can suitably replace it.
Does that help clear things up?
Right. Because after a hard day's work and two hours of taekwondo sparring, there's nothing like falling asleep for a nice peaceful 15-20 minutes.
I like Entity's plan better. Tell me, have you invented a catchy name and stupid propaganda about your "revolutionary" "two-by-four" sleep system?
Damn. Just did it for ya.

I had a friend who tried this last year but failed. He couldn't stick to the scheduled naps after the third day.
It's known as 'polyphasic sleeping' or the 'uberman's sleep schedule' from what I understand.

Notice one critical bit of information provided by the individual endorsing polyphasic sleeping:
I think we now understand why polyphasic sleep has seemed to work for him. It is not only possible but plausible that, if a person ALREADY SUFFERS FROM A SERIOUS SLEEP DISORDER that results in chronic sleep deprivation, polyphasic sleeping may be a better alternative, a lesser of two evils, in a manner of speaking. I should have mentioned this exception earlier.
I have narcolepsy and must take 3 - 4 planned naps throughout the day. If I don't, within a few days, I become a disaster waiting to happen. Compared with the severe fatigue, exhaustion, and uncontrollable sleep attacks from which I suffer in the absence of these naps, I feel SUBSTANTIALLY better and more alert if I take them.
So I shouldn't have been so quick to dismiss polyphasic sleeping as an alternative in such unusual circumstances. I presumed the discussion was not about unusual circumstances, but whether the average person could benefit from polyphasic sleeping. The average person who does not suffer from a serious sleep disorder would not find polyphasic sleeping to be any sort of viable alternative.
I also was in error when I stated that there was no such thing as a nap "technique". There is, but it has ONLY been studied and advocated for SHORT TERM NECESSITY, such as military needs, emergency situations, and endurance contests such as boat racing where crews must function optimally on little sleep for extended periods (up to a few weeks).
It is NOT advocated for prolonged periods, as in totally 'converting' to a nap routine for years or for the rest of one's life, which is what I presumed the thread creator was asking about.
I had read in the past that the first 2 hours of sleep is considered "delta" sleep which means no dreaming and the best rest. After that the sleep cycle becomes less & less beneficial. Maybe sleeping in two hour blocks is more feesable. I would be intersted to see other studies. The 20 min deal would never work for me.
