What Is the Purpose of ‘Sleep’ and Why Do We Need It?

Sleep is like a magic reset button for your body and brain. When you're tired, it's because your brain and body need to rest and get ready for the next day. During sleep, your brain cleans up all the things you learned during the day so that you can think better tomorrow. Your body also heals itself while you're asleep, like when you wake up with less pain after a long day.
