Why do we sleep? | Russell Foster?

We sleep to help our brain and body rest and get ready for tomorrow.

Imagine your brain is like a toy that you play with all day, it gets tired from running around, solving puzzles, and remembering things. When you go to bed, your brain starts resting, just like how your toys sit quietly on the shelf after you're done playing.

Your body also needs rest. While you sleep, your body is working hard behind the scenes: fixing little injuries, growing taller, and getting ready for more adventures the next day.

During sleep, your brain goes through different stages, like going from a quiet nap to a deep dreamy sleep. It's like when you take a break between playing with blocks and drawing pictures, your brain is resetting so it can be fresh again.

Your eyes might even move around under your eyelids, as if they're watching a movie inside your head! This helps your brain remember all the fun things you did during the day.
