During a normal sleep schedule you lie down at 10PM sleep for 9 hours and are up at 7AM. This is 9 hours of sleep. In the first 90 minutes you experience four 'stages' of sleeping, and then enter REM sleep after that and continue cycling between the five stages.
This leads to a grand total of 90 minutes REM sleep for every 9 hours you sleep.
REM sleep is the sleep that makes you feel refreshed and awake afterwards.
But certain people, most likely insane people, developed a different way of sleeping...
Six 30-minute naps every 3-4 hours a day.
After a few sleep deprived days of living this way (because the body gets NO REM sleep) the mind changes how it approaches sleep. Instead of spending 90 minutes entering REM sleep, the mind jumps straight into REM sleep whenever you close your eyes.
This means that (after 8 days of pure hell) you can get over 2 hours of REM sleep (far better than normal sleeping) but only sleep for roughly 3 hours.
This leaves you with six extra hours every single day to do whatever you feel like doing.
Pretty interesting stuff, right?
You have to take the naps. Missing a nap completely leads to oversleeping and a mild relapse (can be cured by taking another nap)
You will spend many many hours alone at night while the rest of the world hibernates.
You need a very flexible schedule, and at least 8 free days to begin the schedule.
Not everyone has the mental capacity for it.
6 extra hours a day
Easier to raise babies
If you wake up on the wrong side of the bed, just wake up again in three hours.
Dreams become more vivid (and lucid)
It would be incredibly trippy.
So I'm thinking of starting this sleep schedule, some time next month maybe, and I'm wondering if anyone here knows anyone who's doing/has done it - or if this interests anyone else here. If anyone's heard of massive side effects I'd like to hear that too.
If you're a little confused feel free to google up on either Polyphasic sleep or the uberman sleep schedule.
