Why is sleep so important? Because what happens when you sleep? Your body washes your brain. And there's a type of fluid that flows through your brain, spinal fluid that goes through your brain. And the purpose of that is to, as we go to sleep, parts of our brain shrinks to allow more room for the fluid to move through. That fluid is very important because it washes out all the toxins and the waste in your brain. And some of the studies in Alzheimer's disease shows that Alzheimer's is caused by a buildup of those very toxins and proteins that are left in the brain if you don't get sleep to help wash them out. So you want to go to sleep. You want that brain to wash itself because it's going to save you later.
