We just learned about the Renal Pyramids and other things about the kidneys.
Let's learn a little about Sleep!
Even though we aren't really in control of our bodies while we sleep, there is a lot of science to why we sleep, and how we sleep.
The body lets out some chemicals into the brain that helps us sleep, the eyeballs move around, our breathing changes, and then eventually we wake up.
We don't know all the secrets of sleeping, but there is a lot of science that we do know about sleep!
