Your brain is like a bunch of young kids cooped up in a house. Throughout the day, the kids are running around making messes, and the dishes and laundry they use keep piling up. The adult(s) can’t take care of the mess until the kids aren’t needing constant attention. You can fall behind on tidying and cleaning but even if you have extra time, you can’t clean up the next day’s messes before they happen.

The brain is similar. While it’s awake, it builds up “messiness” that it can’t take care of until it’s asleep, when the body and brain slow down enough to focus on cleaning up the mess.
