REM Sleep

REM sleep usually first occurs about 90 minutes after you fall asleep; cycles along with the non-REM stages throughout the night.

  • Eyes move rapidly, with eyelids closed.
  • Breathing is more rapid, irregular, and shallow.
  • Heart rate and blood pressure increase.
  • Dreaming occurs.
  • Arm and leg muscles are temporarily paralyzed.

Stage 1: Light sleep; easily awakened; muscle activity; eye movements slow down.

Stage 2: Eye movements stop; slower brain waves, with occasional bursts of rapid brain waves.

Stage 3: Considered deep sleep; difficult to awaken; brain waves slow down more, but still have occasional rapid waves.

Stage 4: Considered deep sleep; difficult to awaken; extremely slow brain waves.

Quality performance requires quality sleep. Quality sleep is a combination of quantity and proper combination of NREM/REM sleep. Most people need a minimum of 5 hours of sleep with 2-3 REM periods.

We need consolidated, restorative sleep:

  • Functioning is a safe efficient and effective way
  • Cognitive, social and physical performance
  • Learning and memory consolidation
  • Emotional enhancement
  • Prevention of health problems
