We all know a good night’s sleep can make a world of difference, but you may not realize just how integral sleep is to your overall health—or that there is a whole field of medicine devoted to the subject.

During this Fight Back episode, we speak with renowned sleep expert Dr. Rafael Pelayo, who talks with us about how important sleep is to our health. Dr. Pelayo is a clinical professor at the Sleep Medicine division of the Department of Psychiatry and Behavioral Science at Stanford University. We cover many key topics, from the basics of getting a good night’s sleep to the physical and mental impacts of not getting enough high-quality sleep each night. We also discuss sleep disorders, the best ways to treat insomnia, and much more.
