Sleep is differing from wakefulness by a lessor ability to react to stimuli
Oh cool! I always thought dreaming was the most interesting part of sleep.
Sleep is a cycle of the body going from REM sleep to Non-REM sleep
Is there a certain amount of sleep required?
During REM (Rapid Eye Movement) sleep the body is virtually paralyzed
That's interesting! What other cycles of sleep are there?
Our bodies go in anabolic state during sleep so our Muscular, skeletal and immune systems can restore and repair
So we do most of our healing while asleep! That's cool.
Also during sleep we dream and later remember it as a fantasy
Oh dreams are really interesting. Do we only dream during a certain stage of sleep?
