The slow waves that we didn't know what their function was when we fall asleep are actually sweeping through and cleaning our brains from the debris that builds up across wakefulness. We can see evidence of volatile emotions, but it's hard to get from mechanistic studies because animals have a difficult time telling us how they're feeling like humans. It's fairly problematic to deprive people of sleep too much, especially children where it's so obvious. Sleep is really important also for a lot of developmental steps that have critical time windows.
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.
