  1. Why do we need sleep?
    • Necessary for survival
    • Allow body to repair itself
  2. How is sleep controlled?
    Sleep is controlled via neurotransmitters:

    Serotonin and Norepinephrine: keep parts of the brain active while we are asleep

    Adenosine: builds up while awake and then is broken down while we are asleep; causes drowsiness
  3. What are the 5 stages of the sleep cycle?
    • Stage 1
    • Stage 2
    • Stage 3
    • Stage 4
    • Rapid Eye Movement (REM)
  4. How do sleep cycles work?
    • Go through an entire cycle (stage 1 through REM), and then repeat.
    • 50% of sleep in stage 2
    • 20% of sleep in REM

  5. What happens in stage 1 of the sleep cycle?
    • light sleep
    • awake easily
    • eye movement slows
  6. What happens in stage 2 of the sleep cycle?
    • eye movement stops
