Polyphasic Sleep

Uberman Sleep

By The Botany Of Solis

UbermanThe Uberman Sleep Schedule (coined by Puredoxyk, the first Uberman sleeper) is a sleep schedule consisting entirely of 20-minute naps, spaced equidistantly throughout the day. In its traditional form, Uberman is 6 equidistant naps throughout each day.

There is nothing known about the long term health effects of being an Uberman, although there have been people who sustained the schedule for as long as a year with no serious health issues.

No one has EVER adapted to Uberman without the help of others, often in the form of a human alarm system.

 

A 6 nap schedule (2h total sleep) will consist of a nap every 4h, it will have a 2h BRAC and a 4h rhythm.

An 8 nap schedule (2h40min total sleep) will consist of a nap every 3h, it will have a 1.5h BRAC and a 3h rhythm.

Exaptation

The adaptation process for Uberman begins with 24-36h awake (or until one enters into a ‘second wind’, a rise in energy) at which point you begin taking a nap for every BRAC (1.5-2h). You might continue with this exaptation for 2-4 days until you are getting regular REM naps, or until you are no longer REM sleep-deprived and unable to nap so frequently.

Adaptation

You may forgo the exaptation and simply go straight into the adaptation phase, as always. Nap every 3h or every 4h on the dot – depending on which rhythm you feel comfortable with.

An expectation of Uberman is to go through a most infamous ‘zombie mode’ where normal cognitive function is severely impaired (due to sleep deprivation). Starting with an exaptation may help alleviate these symptoms, and of course, an 8 nap schedule will be less harsh than a 6 nap schedule to adjust to.

After this, one continues napping as your sleep cycles repartition (either on day 3, day 7, or day 10 – depends on the individual and their initiating sleep deprivation). It takes 3 to 4 weeks to adapt to the Uberman schedule. Some people may adapt faster, but many have taken a whole month to start feeling adapted.

Whilst many people will claim that the adaptation period is finished after a month’s practice, the body will continue to ‘adjust’ to this schedule for many months as continual entrainment improves habituation. Note that usually, people have habituated monophasic sleep for many, many years, and so whilst a month old Uberman should feel fairly rested and alert for about 22h a day, old mono-sleep habits still exist and it may take a long while for those to completely subside.

As habituation becomes stronger, and Uberman should gain some flexibility and be able to shift naps by an increasing amount of time without suffering from a rhythm disturbance. It becomes easier to recover from mistakes or events where naps cannot be taken when they normally would, and even occasionally a longer sleep period will usually not ruin an adapted Uberman’s schedule completely as it would have during adaptation.

Popularity

Uberman Schedule is the most popular and famous of polyphasic sleep schedules because of it’s 2h sleep total. It should be noted that only about 5 percent of the population can get by just fine on six hours of sleep, so perhaps only 5% of people can do this schedule comfortably. A much higher percentage of the population may find an 8 nap schedule more sustainable, as the extra ~40 minutes sleep can make the difference between SWS deprivation and health.

Non-Equidistant Uberman

Because the body gets different types of sleep at different times of the day, non-equidistant timing may be possible, and maybe even beneficial to the sustainability of the schedule. Such a schedule might be achieved by starting with an equidistant 8 nap schedule and, once adapted to it, then cutting out a late afternoon nap. After adjusting to the 7 nap schedule, once adapted to it, then cut out a late morning nap. All three (8, 7 and 6 nap schedules) should be easily transitioned between because they have the same ultradian rhythm, and they have the same nap times. This model would allow for ‘sleep-ins’ (8 naps a day) and ‘workdays’ (6 naps a day).

 

Long Naps at Night

It could potentially be beneficial to take 40-minute naps at night. SWS generally takes longer than REM to transition into because there is a difference in brain wave frequency. The body takes a while to slow down and so this is why traditional Ubermen encounter the SWS crash so quickly, they simply don’t get enough SWS in a 20-minute nap because the first 15-20 minutes is light sleep. Of course, you can repartition SWS, there is no problem in that, but taking 40-minute naps at night may avoid the need to repartition SWS so harshly, and maybe even increase the overall amount of potential SWS available in the schedule (due to increasing the total sleep from 2h to 3h).


Uberman Sleep Refeeds

In some scenarios, a person adapting to the schedule will have an oversleep or ‘crash’ impending, and the best way to deal with a crash is to purposely ‘oversleep’ before the crash comes.

In other scenarios, a person has adapted and repartitioned their sleep, but they are still sleep-deprived of the initial sleep deprivation stage. This is usually because they are getting enough REM and SWS to sustain their schedule, but no excess sleep and therefore not enough to recover. If they are to refeed sleep and catch up from the initial deprivation required to create enough sleep pressure to adapt, then they will regain homeostasis.

There are two notable ways to recover from sleep deprivation on a nap-only schedule, neither may be ideal, but they get the job done. They should be implemented no more than every few days, and usually started around dusk, ten hours before the crash. (assuming the crash is expected around 4 am.)

The first technique, a Core Refeed, is to have a 1.5h core sleep in place of a nap. It is that simple, have a core sleep between dusk and midnight, then continue to nap as per your usual schedule, napping at your next allocated nap.

The second technique, a Nap Refeed, is to start to double your napping frequency, for example, if a [4/8/12] schedule Uberman may want to take extra naps at 6 pm and 10 pm.

These techniques basically increase the amount of SWS an Uberman can get (thus the sleep is around dusk) without disrupting adaptation too much. The more often you do this, the longer it will take to adjust to the Uberman schedule, of course, it should be said doing a refeed is better than crashing as you are intelligibly managing your stress levels rather than succumbing to them.

 

Predicting oversleeps on a nap-only schedule:

When in a sleep-deprived state, there is a balance of sleep pressures called a pressure ratio. This is a ratio of REM pressure vs SWS pressure, and as your body recovers sleep debt throughout our adaptation, the pressure ratio will change. A high ratio means REM pressure is greater than SWS, and low pressure means SWS pressure is greater than REM pressure.

Sleep pressure is caused by glial fatigue, which is greatly increased by CNS activity, and learning processes.

REM pressure increases when glial fatigue causes regulation of a sleep-inducing neurotransmitter in the brain called adenosine (caffeine blocks this receptor site stopping that accumulation being detected). REM pressure increases with greater adenosine reception.

SWS pressure increases with a drop in membrane potential bistability. Calcium signaling is how glial cells integrate and propagate signals in the central nervous system. SWS pressure is regulated by sleep spindle occurrences and periodic lowering of high-frequency brain activity, and in simple terms, the slowing of brain activity is a result of nervous exhaustion (reduction in calcium uptake following chronic depolarization). The brain can perform the actions of SWS at a much lower rate than it normally does when it is awake, so SWS pressure builds more slowly than REM pressure.

Adenosine breakdown is fast during REM (and can clear in 15 minutes) so this system explains why high-frequency REM sleep can be so much more refreshing than large blocks of REM as experienced by a monophasic sleeper.

In the first few days of adaptation, both REM and SWS pressure will rise, but the REM: SWS pressure ratio will be high when REM builds faster. As days pass and REM sleep rebounds in naps, the ratio will equalize and there may be a lulling point. Very often, however, a person’s REM rebound will be so powerful that the ratio drops low and soon afterward there is an SWS rebound.

This means that you can often predict an SWS ‘oversleep’ by realizing an oversleep is anticipated by a really really refreshing REM nap. You might wake up from a random nap feeling like you had a big cup of coffee… beware, as there is evidence that the next two naps the body will try to get SWS at all costs!

 A note on nap-only rhythms

Not everyone’s rhythms are perfect, even when entrained. If after the first week or two you notice that one of your naps is not giving you adequate rest, or you are simply not sleeping in one of your naps, you should experiment with that nap by shifting it forward or backward 30-90 minutes to see if you sleep better having placed that nap differently. This will result in an imbalance in the equidistant nature of the schedule, but being equidistant is not as important as listening to your own body.

A note on exercise

While other schedules support exercise fine, few have been able to do proper exercise while on Uberman and still recover. It seems recovery from cardiovascular exercise is good, but weightlifting and sports can suffer from a low amount of total slow-wave sleep. If you are set on weightlifting whilst Uberman, avoid traditional high volume bodybuilding routines, as the stress can cause a sharp increase in SWS pressure causing you to blackout later that night. Evidence shows you might recover better from high frequency, low volume training whilst on a low sleep schedule.

A note on the 3h total sleep rule

While there is a general consensus that you will be getting less than the recommended sleep totals, it seems frequency plays a role in the total sleep requirements. It may be that sleeping so often in lowers total sleep requirements but for the moment there is no proof or mechanism explaining this.

A note on failure

Often people will try the Uberman sleep schedule only to fail and give up polyphasic sleep completely. There is no reason you cannot move from being an Uberman to any other schedule that shares your Uberman rhythm! Many people have first started on Uberman only to transfer to Everyman and be incredibly successful with their new schedule. In fact, it is recommended that people aiming for an Everyman schedule give Uberman a go before commencing, as Uberman has such a regulating effect on sleep, the entrainment is very beneficial for those wanting to do a milder schedule in the long term.

  1. GeoNOregon, I don’t get it. How many times and how long do you sleep? Do you sleep a total of 6 hours a day with 4 1.5 hour naps?

  2. I adapted the 4h just fine with minimum problem in 5 days, but although I didn’t feel tired anymore I didn’t get any rem and now I can’t even nap anymore I’ve been entirely awake for 2 days and although I don’t feel tired I’m not in the mood for anything (probably due to depression caused by rem deprivation) what should I do? I did it to get more rem and because I was in a hurry for a programming project.

  3. Going to have to test this. I’m one of those people that sleep about 5-6 hours every night, so this might work for me.

  4. I have. I have been on a 4 x 6 hr daily sleep schedule for around 20 years. I only learned about polyphasic pattern yesterday. I had never explored the Internet for alternative sleep patterns.

    I am ecstatic about the benefits of polyphasic sleep. I’m 65, in nearly the best physical condition I’ve been in, in my life, and I was a college and professional athlete. I work on my house, cars, equipment, fabricate, repair 98% of the stuff I own… actually, 100%, with a re- think.

    My chronic pain is so much less, I have great energy, get lots done, work a 12 hr day like I was 30.

    Other things contribute, but the polyphasic sleep schedule is the heart of it all, and enables everything else.

    Cheers, and best wishes.

  5. There’s a recent article by Mark Manson addressing the Uberman Sleep Schedule and what it says about the way we want to discipline ourselves. Very interesting. markmanson.net/self-discipline-youre-doing-it-wrong

  6. They allow the break but they wont keep you long if you “sleep on the job” even if its just through breaktime. I personally had a fruit pack-house position that was 10 hours a day, a 15 min break and a 30 min lunch. slept through my lunch breaks and just ate what I would lunch wise during my morning break. 2 weeks in and HR calls me in stating that “the fact you ‘sleep on the job’ was affecting morale.” Had to go back to a regular sleepcycle, pump my ass full of energy drinks and just had a fuckin sour demeanor throughout my time there. Ironically the fact I cursed like a sailor and the fact I was one surly SoaB after going back to a regular sleepcycle somehow didnt “affect morale.” Cunts.

  7. I personally find that functioning on 4 hour long naps spaced evenly throughout the day works best for me when I havent got time constraints screwing with that kind of sleep schedule. Then again I’m a weirdo that doesnt feel rested without 10 hours on a monophasic sleep cycle.

  8. I’m going to try and adapt the Uberman (U8) w/40m night naps. Im going straight to the adaptation phase, the exaptation phase doesn’t look so good to me.
    In this way I will get 3hrs and 40 min of sleep every 24 hrs that’s 5 20 min naps and 3 40 min naps at night. I think it should work. And I do not think sleep depriving yourself for 24 to 36 hrs before starting your new sleep cycle is a good idea
