There are few things that (literally) every human on earth does, but SLEEP is one of them! To learn more about this universal pass-time, Drew & Liv chat with Dr. Kristen Knutson, a sleep researcher at Northwestern University. Dr. Knutson's research studies how sociocultural factors interact with physiology to impact sleep, as well as the relationship between sleep and chronic disease. This episode will tell you all you need to know about getting a good night's rest - and do lots of mythbusting while we're at it.You can follow Dr. Knutson on Twitter @klknut.
