      • Deep sleep – Delta waves + Theta waves
    • Stage IV
      • Deepest of sleep – Large Delta waves sweep brain every second - +50%
    • REM SLEEP
      • Brain waves similar to awake person – Beta Waves
  • 5. Circadian Rhythm
    • Biological clock that is roughly 24 hours
    • Regulates physiological responses
    • Even w/o cues people respond to this
