I read this in my Health book in school and thought it was rawther interesting.
"Through research,scientists found people experience two kinds of sleep. One kind is characterized by rapid eye movements (REM stage),while the other is called the state of relaxation. During this state your body may go through four stages and then enter the REM stage.
Stage 1:Occurs just after you fall asleep. Everything slows down,and you could be easily awakened. Some may experience muscle spasms just before falling asleep due to bursts of brain activities.
Stage 2:Brain waves in quick bursts. Eyes roll slowly from side to side. You still could be awakened.
Stage 3:Deep calm sleep. Brain waves are long and slow. Muscles are relaxed,heart rate slows,temperature and blood pressure drops.
Stage 4:Deepest level of sleep. Large slow brain waves. Breathing is even. If an alarm went off during this stage you may not hear it. Most nightmares and walking in your sleep occurs during this stage.
REM:After stage four,your brain moves to the REM state. Eyes dart back and forth and much of the dreaming takes place during this state. The body is almost paralyzed state while breathing and heartbeat are irregular."
Pretty interesting..ehh?
