  1. Shut Eye! Ms. Heaffner Shamrock Middle School

  2. How many of you go to bed by Nine o’clock? 9:00 pm

  3. Who wakes up at six o’clock?

  4. How many hours of sleep did you get last night? ??? ??? ???

  5. Do you think that was enough? • If not, what kept you up too late?

  6. How many hours a night should we sleep? Why? • The optimal amount of sleep is seven to eight hours. • Because without this there is many negative side effects to not getting enough sleep.

  7. How much sleep do teens need? • Most adolescents need at least 8 1/2 hours of sleep each night, according to the National Sleep Foundation. • But it estimates that only 15 percent of young people get that much, with 25 percent of teens getting less than seven hours.

  8. What do you think will happen if we don’t get the right amount of sleep? This is what happens to your body if it's deprived of sleep: • You have problems with memory and concentration. • You have problems finding the right word. • You get irritable. • Neurotransmitters in the brain become altered. • Children's growth will be stunted. • You become more susceptible to infection. • At its extreme, sleep deprivation can lead to death.

  9. What are the stages of sleep? • There are Five stages of Sleep.

  10. Stage 1 • This is experienced as falling to sleep and is a transition stage between wake and sleep. • It usually lasts between 1 and 5 minutes and occupies approximately 2-5 % of a normal night of sleep. • Sometimes body will twitch or muscles will jump.

  11. Stage 2 • This is the "baseline" of sleep. • This stage is part of the 90 minute cycle and occupies approximately 45-60% of sleep.

  12. Stage 3 and 4 • It is called "slow wave" sleep because brain activity slows down dramatically from the "theta" rhythm of Stage 2 to a much slower rhythm of 1 to 2 cycles per second called "delta" and the height or amplitude of the waves increases dramatically. • In most adults these two stages are completed within the first two 90 minute sleep cycles or within the first three hours of sleep. • Contrary to popular belief, it is delta sleep that is the "deepest" stage of sleep (not REM) and the most restorative. It is delta sleep that a sleep-deprived person's brain craves the first and foremost. • In children, delta sleep can occupy up to 40% of all sleep time and this is what makes children unwakeable or "dead asleep" during most of the night.

  13. Stage 5 • REM (Rapid Eye Movement Sleep): • This is a very active stage of sleep. • Composes 20-25 % of a normal nights sleep. • Breathing, heart rate and brain wave activity quicken. • Vivid Dreams can occur. • Sleep Specialists call this 5th stage of sleep "REM" rapid eye movement sleep because if one is to watch a person in this stage, their eyes are moving rapidly about. • After REM stage, the body usually returns to Stage 2 sleep.

  14. What stage is the most important and why? • Stage 3 and 4 • Contrary to popular belief, it is delta sleep that is the "deepest" stage of sleep (not REM) and the most restorative. It is delta sleep that a sleep-deprived person's brain craves the first and foremost. In children, delta sleep can occupy up to 40% of all sleep time and this is what makes children unwakeable or "dead asleep" during most of the night.

  15. Has Anyone ever lived in another country? • If so, were sleeping and waking patterns any different there?

  16. What are the benefits of using good sleep habits? • Prevents grumpiness • Gives you energy • Clears your mind • Helps your immune system stay healthy • Increases your ability to pay attention • Recharges your body (batteries)
