Hack Your Brain: Polyphasic Sleep

Have you ever wondered why humans, the most
advanced species on Earth, need so much sleep?

You may say that it’s needed to repair and replenish our body tissue, but that can’t be the answer. Giraffes, for example, can weigh upwards of 4,000 pounds yet they only sleep on average 1.9 hours per night. Then it must be for our brains! you may say, but that’s not true either.

Humans have been shown to function fine on only two (yes two) total hours of sleep per 24 hour cycle.

Scientists really don’t know much about our sleeping patterns, which is a shame because we spend about a third of our lives sleeping. There is no defined biological reason why we sleep so much. In fact, you could go so far as to say it’s a major disadvantage in our evolutionary process.

Imagine how much more you could accomplish in your life by sleeping less.

You may know that sleep is divided into five stages. Polyphasic sleep concentrates on the fifth and most important stage of sleep, rapid eye movement (REM.) This is the most beneficial stage of sleep; it is when the brain is most active and is when dreaming occurs. REM is the only stage of sleep that is actually required to survive and function normally. The interesting part of all this is that you only spend 1 to 2 hours in this stage of sleep every night. The other 6 or so hours spent asleep every night are seemingly wasted.

Polyphasic sleep cycles basically cut out the other useless phases, giving you an additional 4 to 6 hours of time awake.

The trick involves tricking your brain into immediately entering the REM stage of sleep, skipping the other four. Everyone has experienced this at some point in their life.

If you’ve gone a long period of time without sleep, and take a nap, you will find that you immediately start dreaming. This happens because your body is trying to catch up on lost REM sleep. The premise of polyphasic sleep then, is to train your body to enter REM sleep at multiple set times during the day with short 20 minute naps. If you are a fan of lucid dreaming, you will enjoy this even more because you will pretty much automatically become lucid while you sleep, without trying, multiple times per day.

There are six different ways to accomplish this, which I will outline below.

Monophasic Sleep

This is the most common way that almost everyone sleeps. However, it is completely unnecessary and only popular because you have been raised to sleep this way and are now conditioned to it. It involves sleeping 8 hours, with 2 hours of total REM sleep.

Polyphasic Sleep Cycles

This is where the fun starts. There are five commonly accepted polyphasic sleeping cycles, and none is better than the other.

What you need to do is pick what works best with your schedule. The Uberman, for example, would not work for a 9-5 worker. The siesta might be more effective in that case. The five different cycles are listed in order of difficulty, with the Siesta being the easiest, and the Uberman being the hardest.

The Siesta

This sleep cycle is actually pretty common around the world in warmer countries such as Latin America, where the temperature is so hot during the middle of the day that people retire to take a short nap after lunch. It involves 6 hours of core sleep and one short 20-30 minute nap. You will find in these countries that most shops close during the early afternoon, as everyone is ‘busy’ taking their siestas!

The Everyman (2 nap, 3 nap, 4 nap)

The Everyman is basically like a climbing ladder that details how much many naps are required depending on how much core sleep you want to cut. Each nap shaves off an astounding hour and 40 minutes from your core sleeping time.

The Uberman

The Uberman is only for the most hardcore polyphasic sleepers. It involves six evenly spread out naps every four hours and completely eliminates any core sleep you may have needed before. It is the most difficult cycle to get used to, but once accomplished, you sleep for two hours a night, freeing up the other twenty-two to do whatever you want.

Important Things You Must Know
Do NOT oversleep or skip naps. If you oversleep you WILL throw off the entire schedule and feel exhausted for up to 24 hours. If you skip a nap (by more than a couple hours with the Everyman, or by 30 minutes with the Uberman), the same thing will happen.

• Make sure you have a period of free time (up to a month) to adjust to the cycle.
• The first week or two is the most difficult part when trying to adjust to any of these cycles. Beat this phase without oversleeping or skipping naps, and you will have successfully hacked your brain.
• You must have something to fill up all your newfound time with, else you will get bored and find that falling asleep may be the easiest thing to do. Find a big project and work on it throughout the adjustment phase.
• Enjoy your newfound freedom. Don’t worry about negative effects as people have done each cycle before, and after being examined by doctors after years, and been found perfectly healthy. In fact, people only stop these cycles because they find it is difficult to run on a sleeping cycle which contradicts the entire rest of the world. Who knows, one day we may all be Uberman sleepers!

    Your website has so much realism , and truth , not like the internet which is 90% garbage ,please keep it this way. Nice and Clean , full of truth and things we as humans love to learn , it teaches us .

      I love this site, more than any other. It’s just about the only site I read now a days. And by only really reading this site, it’s allowed me to cut out the crap from my life that is the internet, and apply what I’m learning here to real life. It’s the best freedom.

  • Truth says:

    This site is pretty good, until you posted this article.

    The uberman sleepcycle is NOT a way to get more time out of each day or whatever. Research showed that sleeping/napping 6 times 20 minutes is superior than just sleeping 2 hours in a row but INFERIOR to sleeping 6-8 hours in a row or simply dividing it in two parts.

    The uberman was only used in settings where they could NOT sleep much, suggesting this for long term is both harmful for your health AND your brain.

    In this time and day, we want to maximize productivity/creativity, sleeping for 2 hours, no matter how you slice it, won’t maximize either of them.

    Read this if you’re still in doubt:


    PS: Even the most respected researcher on sleep(look for it on amazon, book is called polyphasic sleep), does not recommend sleeping this way. 2 hours is simply not enough.

    Every body understands that modern life seems to be expensive, however people require money for various issues and not every man earns big sums money. Therefore to receive good credit loans or sba loan would be a correct way out.

    The deep phases of sleep are necessary for human health, any first year psych student knows this. The blood that normally flows into your brain slows down and allows tissue regeneration everywhere in the body to increase significantly. You may not die by cutting the deeper phases out of your schedule but you will probably age faster.
    Uberman sleep schedule users also report eating way more food than before because they burn more calories. I think it would be safe to assume that more burned calories would mean more mitochondrial activity and therefore more free radicals, which on top of the lack of regenerative deep sleep would make you age even faster.
    We are not giraffes, and anyway, they only live about 20- 25 years. Just because a human can “function fine” on less than two hours of sleep doesn’t mean that it won’t cause them to age faster.
    So please don’t act like this is a good idea until there are clinical trials on the subject.

    A much better article on how to get good sleep by giving it the respect it deserves:

    Polyphasic sleep is not natural and is not recommended! This post goes into the details: http://greenminimalism.com/2013/06/15/is-polyphasic-sleep-healthy-dangers-of-polyphasic-sleep/

    DO NOT try a polyphasic sleep schedule – I have and it wasted a month of my life.

  • uberlisa says:

    I have never been much of a nap taker, but I’ve grown up surviving on 3-4 hours of sleep a night on a regular basis since my elementary school days. About halfway through my college career, a friend talked me into trying to get 6 hours of sleep a night. It seemed to work ok, but the habit stuck. I couldn’t say much for any method of sleep…but I grew up an honor roll student most of my life running on only a few hours of sleep a night. People that claim this method isn’t successful have obviously not given it an honest try. That is all.

    great article! I actually just published my experiment doing the polyphasic sleep. check it out here: http://www.alexfortin.com/polyphasic-sleep-schedule/ Let me know what you think. :)
