84: The Science Behind Sleep

Years ago, people believed when you slept your whole body shutdown. But when sleep studies became a thing in the 60s/70s, we started learning quite the opposite!! Your brain actually is totally active during your sleep, and doing a lot of work to keep you healthy! In this episode we go through the science behind our sleep, what happens when we cycle in and out of sleep cycles, what sleep apnea is, why snoring isn't normal, and why we would certainly die if we didn't sleep.
