Mystery of Refreshing and Restorative Sleep: What You Need to Know About Deep Sleep and Dream (REM) Sleep
- Stage 1 is the transition from being awake to falling asleep. During this stage, brain waves and muscle activity start to slow down. While in stage 1, you may experience the feeling of falling, which is followed by sudden muscle jerks.
- Stage 2 is a period of light sleep. During this stage, eye movement stops and brain waves become slower, with occasional bursts of rapid waves. You may have spontaneous periods of muscles tightening and relaxing. Your heart rate slows and body temperature drops.
- Stage 3 is deep sleep. Deep sleep is also referred to as slow wave sleep, which presents slow brain waves mixed with smaller, faster waves. It is most difficult to wake up from the deep sleep stage. During stage 3, blood pressure and body temperature drop, breathing slows and the body becomes immobile. The more sleep deprived you are, the longer your body will stay in the slow wave portion of the cycle.
- Fast and desynchronized brain waves, similar to when the brain is awake
- Fast, irregular and shallow breathing
- Temporarily paralyzed muscles
- Increase heart rate and blood pressure
