I am sleepy! I am going to lay down and rest my eyes.
ZZZZZZ!
Melatonin is a hormone that affects sleep cycles and increases drowsiness.
REM Sleep Energizes- rapid eye movement and dreams occur, and brain wave activity appears similar to that when you are awake. This occurs a lot of the time with people fall asleep on the couch.
Non-REM Sleep is Restorative- is the sleep period that the body rests. Both your body temperature and your energy use drop; the sensation is dulled; and your brain waves, heart rate, and breathing slow. This occurs when you fall into a deep sleep.
