What Is The Point of Sleep?

Your body uses sleep to rest and get ready for the next day, just like you rest after playing too long.

When you're awake, your brain is working hard, it's like running a race. Every time you learn something new or have fun, your brain is using up energy. That’s why sometimes, after a long day at school, you feel tired and want to lie down.

While you're sleeping, your body is doing important work behind the scenes:

• Your brain is cleaning out all the extra stuff it collected during the day, like when you wipe off a messy table after dinner.
• Your muscles are getting stronger, just like how your legs feel more powerful after you rest between jumping on the trampoline.
• You’re growing taller and learning new things, even while you're fast asleep.

So sleep is like a secret power-up for your body. It helps you be ready to play, learn, and have fun again tomorrow!
