Some researchers hope to develop sleep into a form of medicine, reports Wired.
“Sleep is so critical for so many parts of our body and our mind,” says Aric Prather, a sleep scientist at UCSF. It strengthens the immune system and helps regulate metabolism. It can clear out toxins that build up in the brain and prevent neurodegenerative diseases. “Sleep is like the dishwasher of the brain,” Prather explains in WIRED’s latest “Five Levels” video.
