Why Do We Sleep?

"Why do we need to sleep every night?"

💡 Simple Explanation

Your body is like a phone that needs to charge! When you play and learn all day, your brain gets tired and fills up with 'brain garbage' - messy stuff from all your thinking. When you sleep, tiny cleaners in your brain sweep up all that mess. Your body also fixes any boo-boos and grows stronger. Plus, your brain replays what you learned so you remember it better!

🎉 Fun Fact!

Dolphins sleep with one half of their brain at a time so they don't forget to breathe!
