There are four stages to non-rapid eye movement sleep (NREM):
Stage 1 is transitional sleep
Stage 2 is light sleep
Stages 3 and 4 are the deep stages of sleep during which the body repairs and builds tissues. These stages have the biggest and slowest brain waves ‘delta waves’. Stage 4 is always more intense and each stage can last from 5-15 minutes, during a sleep cycle people progress through all stages then the cycle starts again.
There are also two different sleep states: NREM and rapid eye movement (REM) sleep, sometimes called dreaming sleep. In REM sleep we are almost paralyzed, with large muscles unable to move – only the heart, diaphragm, eye muscles and the smooth muscles (such as the muscles of the intestines and blood vessels) are able to move.
