What the Heck?

Episode 154- Rhythms of Sleep


Listen Later

Welcome to What The Heck season 4! This podcast explores unexplained phenomena using stories gathered from various sources, then applies an academic research method to find theories and solutions for each one. So far, we've been unsuccessful in finding any concrete answers, but a few of the stories we've covered have been solved. Today, we're looking at why we sleep. It's always fun to look at something we think we know. Sleep is one of those. There is a long list of things that happen while we sleep, but we don't know why we need to be asleep for those things to happen. Research is constantly being conducted to find the answers. What is a Circadian Rhythm? What actually happens when we sleep? Why would we need to be asleep for these things to happen? Listen in to find out!
