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 dont 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.
