  1. Anatomy of Sleep ZZZZZZZZZZZZZZZZ

  2. Did you know…..? The body rests during sleep. The brain remains active.

  3. Sleep = • Two sleep states and 5 stages • non-REM & REM (rapid eye movement) • 90-100 minute cycles

  4. 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

  5. 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.

  6. Research shows Teens need 8½ - 9 hours of sleep a night … DO THE MATH !

  7. 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.
