Get By On Less Sleep
I am a bit skeptical but Glen Rhodes has a good essay on the beauty of biphasic sleep cycles:
“Naps are the key to direct Theta brainwave access. Theta brainwaves are the brainwaves of hyper awareness. The more theta you have during your waking hours, the more creatively intelligent you are–it’s really that simple.”
The idea is to have two short sleeps per 24 hours instead of pushing all the sleep into one 8 hour stretch:
“The key thing is, it MUST be divided up into two distinct sleep sessions¬†per day.¬† It’s not enough to just get 4.5 hours and say “that’s my sleep done for today”.¬† You’ll have a hell of a time staying awake for the remaining 19+ hours. You’ve got to divide it into two (or more) sleep sessions. The REM sleep you achieve has to be spaced throughout the day for it to have the¬†proper “flushing” effect.”
