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!
