Eli5: Why do we need to sleep so much, what happens in the body when asleep that cannot happen while normal resting or relaxing? Or is it just for the brain?
We don’t really know but I like think it’s kinda like a computer. If it’s up for a whole year with no shutdown, processes and apps will eat up ram (even though they aren’t running). Shutting down your head computer is the only way to fix that
