NREM 1

Sleep Stage #1: (Sleep Onset) alpha>>>theta waves, light sleep, hypnic jerk, hypnagogic images (once a night for a few minutes)

NREM 2

Sleep Stage #2: characterized by its periodic sleep spindles, decreasing body temperature, bursts of rapid, rhythmic brain-wave activity, slowed breathing, and heart rate. about half the night is spent in this phase.

NREM 3/4

Sleep Stage #3 + 4: called slow-wave sleep, delta sleep, or deep sleep. vital for restoring body's growth hormones and good overall health, which is why it occurs in the first 30 min of sleep. plays a critical role in physicial growth (Pituitary) and physicial recovery

REM Sleep

Sleep Stage #5: Rapid eye movement sleep; a recurring sleep stage during which vivid dreams commonly occur. also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active.
