Life Slices

Sleep. As humans, we know we need it and we know that when we don’t get enough, it can affect us all day long, if not longer. But what do we really know about it? What happens to our bodies and brains when we sleep, perchance to dream. Thankfully, there are scientists around the world studying all the things about it the rest of us don’t even think about. Dr. Michael Grandner of the University of Arizona, Director of the Sleep and Health Research Program, and Director of the Behavioral Sleep Medicine Clinic, joins host Steve Fisher to talk about what happens when we sleep.
