Anatomy of Sleep ZZZZZZZZZZZZZZZZ
Did you know…..? The body rests during sleep. The brain remains active.
Sleep = Two sleep states and 5 stages non-REM & REM (rapid eye movement) minute cycles
Non-REM sleep First four stages Stage one & two- drowsiness, easily awakened “Deep sleep" stages three and four- when awakenings are more difficult ;where the most positive and restorative effects of sleep occur
Final Stage REM sleep - active sleep where dreams occur, breathing, heart rate increases and becomes irregular, muscles relax and eyes move back and forth under the eyelids.
Research shows Teens need 8.5 – 9.5 hours of sleep a night … DO THE MATH !
It’s not all your fault… Your brain naturally changes during adolescence: the body's circadian rhythm (sort of like an internal biological clock) is reset, telling you to fall asleep later at night and wake up later in the morning.
So… What’s a Body to Do?
