Transcript
Well, we've read the material about sleep cycles and talked about, in theory anyway, what an optimal cycle would be for your average sleeper. If you remember, there was stage one through three, followed by REM sleep, where we do our dreaming. Today we'll look at some interesting studies done into sleep cycles, which all began with some stories about someone I'm sure you've all heard of before, Leonardo da Vinci. Da Vinci had a really interesting and extremely short sleep cycle that we'll talk about, and then look at experiments done by Dr. Claudio Stampi in Italy, trying to recreate da Vinci's incredible short amount of sleep, to see whether it is in fact possible or even healthy.
