Has anyone ever tried
polyphasic sleep?
One of the things that sucks most about sleeping is that it takes up so much of our time. Think how much more shit you could get done without having to sleep 7, 8, or 9+ hours a night.
I'm particularly interested in what is known as the uberman sleep pattern, where you only sleep for 20 minutes, 6 times a day, for a total of 2 hours of sleep.
Monophasic sleep is extremely wasteful. When we sleep, we go through cycles. One of these cycles, REM sleep, is where most of the benefits of sleeping come from. We don't spend too much time in this stage compared to the other stages. So the trick is to get your body to dream sleep immediately upon falling asleep. Another problem is that you have to take your 6 naps within 30 minutes of their scheduled time or you will get extremely tired and be fucked.
It's probably not healthy, but it is kind of an interesting thought.
