Can you tell me a little bit about sleep?

It is important to know how valuable sleep is for the body’s normal functions. In the old days people thought that when you slept your brain and body were inactive. That is not the case, because of today’s research. All night your body and brain do a lot of work that’s important for your health. There are two main types of sleep that we cycle in and out of when we rest, something called rapid eye movement (REM) and non-REM sleep.
