Why do children grow taller while sleeping?

You've probably heard someone say, "Sleep helps you grow!" And you might wonder — am I really getting taller while I'm lying there, totally still, dreaming about space penguins or math tests? The answer is yes. And the reason is actually pretty cool.
Inside your bones, there are special zones called growth plates — thin layers of cartilage near the ends of your long bones, like the ones in your legs and arms. These growth plates are like construction sites where new bone cells are constantly being made, stacking up to make you taller.
