Everyman SleepThe term "Everyman" sleep was coined by the same person who coined the term Uberman: PureDoxyK. Her personal anecdotal evidence has done a lot to push polyphasic sleep to the masses. Indeed, that is the very idea behind everyman sleep.
Most people work during the day. A relatively normal work day would be 8 hours long, though many people will work a little more than that. So, one ideally would have about 9 hours straight without having to do much sleeping. Uberman Sleep does not really allow for that. Sure, you can take a nap at lunch, but that only leaves about 3.5 hours on each side of that nap or a total of 7 hours. So, one would have to find another time besides lunch each day to take a nap. Dymaxion Sleep would be an option since it would allow for a total of about 11 hours of sleep on either side. But, many people have difficulty adapting to Dymaxion Sleep, much more than do to Uberman due to the nature of how one's sleep pattern needs to adapt.
Everyman is designed to work around normal people's lives. It consists of a core sleep period at night when people are already used to sleeping and then a limitted number of naps throughout the day, usually three. Because of the addition of the core sleep period, after adapting to it, one's naps are significantly more flexible in Everyman than they are in Uberman or Dymaxion.
The "traditional", or maybe I should say original, Everyman sleep schedule is a core sleep period from 1-4am, a nap at 9am, one at 2pm, and one at 9pm. But, for the working individual, having a core sleep from about 11pm-2am, then a nap at 7am, one at 12 pm, and one at 6pm might work better; I know it would for me. Also, in general, the naps are noted to be able to be moved some or even skipped without hitting the wall that happens in Uberman. So, if the three naps mentioned don't fit your schedule, just move them and the core sleep to whenever they do fit your schedule. A good rule of thumb is not to have less than 4 hours between naps and probably no more than 8. The reason not to have a period greater than 8 hours is that then missing that nap might really drag you down by the time you get to your next scheduled nap. On the other hand, the whole idea behind Everyman is that the naps are adaptable, so you don't have to wait until your next planned nap if you are tired and have time to nap.
PureDoxyK has now been on the Everyman schedule for five to ten years. She has noted that if she skips a nap, then she ends up needing a longer amount of sleep at night. With two naps, she needs about 4 and a half hours in her core sleep. Depending on your schedule, you may just want to shoot for this, Perhaps a schedule of core sleep from 1-6am, a nap around 12, and another nap at 5 or 6 would work well for you. Of course, some people will read this and say, "I can get only 5 hours of sleep a night without naps during the day." This may be true for you, but for most people, this would mean that they would end up feeling somewhat tired during the day and really needing a nap. Of course, that's the point. Everyman is a very natural schedule: more natural than Uberman.
If you are interested in just experimenting with polyphasic sleep but are not sure if you can do it, then Everyman might be a good choice for you. You may want to check out either the comparison of sleep schedules page, or my Which sleep schedule is right for me? page.
