Episode notes

Sleep is behaviorally defined as an inattentive state where we're less attentive to the world around us. It's reversible though, so we can definitely wake ourselves up unlike coma. We usually have a characteristic posture and it's homeostatically regulated. If we don't get enough of it, our brains will demand more of it to make up for the sleep that we've lost.

Dr. Gina Poe has spent nearly four decades studying the science of sleep, and how we can all get a better night’s rest by making some simple changes in our lives. In this episode Poe dives deep into what she’s learned about sleep during her career, including the stages of sleep, why you’re waking up in the middle of the night, why some people remember their dreams, the best bedtime routines, and the real-life consequences when you miss a night’s sleep. Dr. Poe is a professor of Integrative Biology and Physiology at UCLA, where she is also the Director of the school’s Sleep and Memory Laboratory, which investigates the mechanisms by which sleep traits serve learning and memory consolidation.
