These are overviews of the most common alternative sleep schedules, and not detailed guides. Please follow the link and read the appropriate adaptation guide page before attempting any of these schedules. Also keep in mind that these schedules are not set in stone and many people choose to customize them to their needs.

Monophasic Sleep:

Monophasic is pretty much the most common sleep schedule in the world. Monophasic sleep essentially consists of sleeping once per day, usually for between 7 and 9 hours per night. Monophasic is not the best way to sleep contrary to popular belief, but instead it is a byproduct of the long work hours of the industrial revolution that has remained a cultural norm even as work hours have shortened.


Segmented Sleep (biphasic): 

Segmented sleep is considered the most natural sleeping pattern according to common scientific literature. It consists of two sleeps, both at night time, first going to sleep at dusk, and secondly waking at dawn, synchronized with the local lighting patterns, sunrise and sunset. If a person changes their sleep from monophasic sleep to segmented, then after some acclimatization they will experience a change in hormone regulation, energy metabolism and a profound mental clarity throughout the day, and the middle of the night. A Segmented Sleeper typically sleeps between 6 and 8 hours a day.


Siesta Sleep (biphasic):

The siesta sleep is very common in Spain, Germany, and various other European countries. Spain specifically closes shops in the middle of the day for a few hours so that people can go home for lunch, napping, and other quiet activities. The siesta schedule consists of 5-6 hours of sleep at night and a 20 to 90 minute nap in the early afternoon. This form of sleep matches with our natural Circadian rhythm, and is commonly known by scientists to be healthier than monophasic sleep, with the short nap increasing productivity and alertness during evening hours. A biphasic sleeper typically sleeps between 5 and 7 hours a day.


Triphasic Sleep:

Triphasic was coined and made popular by Leif,  and is an efficient and simple schedule. There is little adaptation involved in a change from monophasic sleep to this schedule, and 3 to 5 hours extra are gained each day. The reason for its ease of adaption is that, similar to biphasic sleep, it aligns with the Circadian rhythm, with a nap after dusk, a nap before dawn, and a nap in the afternoon. A Triphasic sleeper typically sleeps between 4 and 5 hours a day.



Everyman Sleep:

The Everyman schedule is the most successful reduced-sleep schedule to date, it is constantly increasing in popularity, and people have achieved it without compromising their current health. While monophasic, biphasic, and triphasic schedules are all Circadian centric schedules, Everyman schedules rely on both Circadian and Ultradian Rhythms. This makes Everyman schedules have a significantly more difficult adaptation period than all of the previous schedules, as the consistency of times between sleeps matters much more. That being said, Everyman is still significantly easier than any of the nap-only schedules. Everyman schedules include Everyman 2 (E2) which is a with core sleep between 4.5 and 6 hours and two 20 minute naps; Everyman 3, with a core between 3 and 4 hours and three 20 minute naps; and Everyman 4 with a core between 1.5 and 2.5 hours, with four 20 minute naps.


Dual Core sleep is a derivative of the other schedules but with a core sleep around dusk, a core around dawn, and a number of naps in the afternoon. Dual core schedules can have the benefits of both segmented sleep and siestas and so is theoretically very healthy. DC1 is two cores totalling about 5 hours sleep, and one nap in the middle of the day. DC2 is two cores totalling about 4 hours sleep, and two naps throughout the day. DC3 is two cores totalling about 3h sleep, and three naps throughout the day.


Uberman Sleep:

Uberman is the most commonly attempted, and most failed of polyphasic schedules. This is largely due to a misunderstanding of the difficulties associated with its adaptation period. Uberman is the most well known nap only schedule, and is an extension of the Everyman schedules, to the point of getting rid of the core sleep entirely. While Uberman is extremely difficult, it can have great benefits by increasing the amount of time in a person’s day drastically. An Uberman will have 6 or 8 x20 minute naps a day, with total sleep time ranging from 2-3 hours a day.



Dymaxion Sleep:

Dymaxion is another popularly attempted schedule, although its difficulty is even greater than Uberman, to the point of being nearly impossible. It’s predict only the genetically mutated DEC2 gene ‘very short sleepers’ can be successful following such a schedule, which would includes far less than 1% of the world population. The Dymaxion schedule was coined by Buckminster Fuller, and involves sleeping 4 times a day for 30 minutes. Even though the Dymaxion schedule does not increase available awake time any more than Uberman, it is prized for the increased convenience to the person’s social and work life.


SPAMAYL is the younger, fresher cousin of Uberman. SPAMAYL stands for Sleep Polyphasically As Much As You Like. SPAMAYL was coined by Rasmus, and so far it seems he is the only person to be successful long term. While Uberman has a sense of extreme rigidity, SPAMAYL takes in extra sleep for extra flexibility. SPAMAYL is more flexible than Uberman, in that Rasmus could move things around for social events and a SPAMAYLer can expect to take no less than 7 naps a day, and often need as many as 10. Rasmus usually get between 2.5 and 4 hours of sleep per night.

    So what is the best polyphasic thing for students? Because I can’t sleep from 7:00 to 3:10 because of school, so how would I be able to do polyphasic

    • Chase Reply

      I think what you would do is just move it back a few hours so you’re going to bed a lot earlier

    • Nolan Reply

      don’t, go to bed at 5:00 or as soon as you can, get 60 minutes, get back to bed by 12:00 and get 4 hours, wake up at 4:00 but get back to bed by 5:00 and get another 60 minutes. wake up at 6:00 and start your day

    i have extreme difficulties sleeping. On good night I get 4-5 hours. No amount of “sleep hygiene” helps. I’m terrifed of medication side effects. I’ve have horrible side to other meds, I can’t get myself to take anything now.

    All my life I get wide awake at night. I’m usually not sleepy till two or three in the morning. And a lot of those I wake back up because of noise, I am a very light sleeper,.

    If I somehow manage to get to sleep before 2 am my sleep is very restless and I toss and turn.

    But the absolute worst is this: I finally got a job after years of being out of work..but the bad part is I could only get a morning shift. I have to get up at 6 am not being able to sleep well has made me extremely anxious when I go to bed, I worry I won’t sleep, Then it’s starts a vicious cycle. I can’t sleep I know I need to sleep. So now I get anywhere from 2 hours of sleep to none at all.

    I have family to take care of, shopping, chores, cooking…..I might get a 2 hour nap some days but the lack of sleep is profound, and extremely affecting all areas of my life. I’m in physical pain from lack of sleep It’s a living hell.

    I know there are natural ways to sleep better without meds, and sleep clinics, but I don’t know how to go about finding them. Where can I get some help?

    I’m a 44 year old woman, I live in southeast Michigan.

      Hey Kathy,

      im a student and currently aiming for my exams. i did the everyman last year around a 3 hour and later on 4,5 hour core sleep. It kinda worked rly well but i couldn´t take my naps everytime i wanted to do durign the day, because of the sessions at the unversity.

      3-4 weeks ago i started a biphasic sleep schedule. I´d rly recommend it. In the beginnign i had to get up early as u did and i felt rly tired at the end of the day so i felt as sleep far earlier for around 1,5 hours or 3 hours (didn´t needed a timer)
      My body woke up on it´s own. And right now i just adeptet to it and i feel great.
      I go to bed every day at 21 o´clock and sleep for 1,5 hours-3 hours, sometimes even the resting gives me energy if i cant fall asleep for some reason(fu up the day before…)
      It´s kinda semi-sleep then similar to takign a nap.

      Whatever basicly i sleep every day 21-24 cest and 4am-7.15am.
      Those 4 hours peace at night feel great to rest or to do everythign i like to do.
      I guess you could do the same by doign it 1 hour earlier so you get up at 6 am.

      Btw at the beginnign i figured out that 4,5 hours are the best core sleep for me.
      so i´d sleep 21-22.30 and 4-8.30 am. But i wanne get a 24/7 sleep schedule and soemtiems i cant sleep till 8.30 during the week so i started to use the 3-3 hour scheduel succesfully so far;)

      good luck, mayby it was helpful or a good idea

      greetings philipp

      btw dont give up to early you´ll need some time to adjust or your body might tell you the right timings on its own

        btw you could use those 4 hours at night to watch a film, read a book, spend some time with your husband etc.

    How about 4 naps of 90 minutes for a total of 6 hours? I read that a 90 minutes is a complete cycle of sleep. Has it ever been tried? It seems to me like a more realistic version of the Dymaxion sleep offering more hours overall and better quality of sleep for each naps.

    Would this work for frequent travellers? For example professional pilots? Does the software account for a change in timezone and the ‘body clock’ not being in sync with this?
