Why do we sleep

Why do we Sleep?

Russell Foster is a circadian neuroscientist. Translation: He's an expert on the body's sleep cycles. In his 21-minute, fact-filled and sometimes humorous speech, Foster slays several common sleep myths. Not all of us actually require eight hours of sleep. And, sorry, while heading early to bed can make you healthy, there's no proof that it can make you wealthy or wise.

Foster says it's high time we take sleep seriously as a society. "This isn't some sort of crystal-waving nonsense," he says. "This is a pragmatic response to good health. If you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health." And what's not to love about that?
