1069 - Why do we need sleep?

We need sleep for several important reasons. When we sleep, our body:

  1. Repairs and grows: Our body fixes damaged cells, builds new muscles, and grows stronger bones.
  2. Remembers new things: Our brain helps us remember what we learned during the day.
  3. Fights off germs: Our body produces special Helpers that fight off germs and keep us healthy.
  4. Feeling happy and fresh: Sleep helps us feel happy, relaxed, and ready to play or focus on schoolwork the next day.

Think of sleep like a magic recharge button that makes us strong, smart, and happy.
