Sleep Is Good For Your Brain - Jeff Iliff

Brains, like other muscles and biological processes, create waste when they work all day. And sleep is the key to cleaning up that waste. Neuroscientist Jeffrey Iliff explains that brains are almost as active at night as they are in the day, but they're doing different things. Iliff explains how during sleep our brains clean out the waste plaque that can prevent it from running smoothly and could potentially contribute to the development of Alzheimer's disease.
