“non-REM Sleep
The type of sleep not associated with dreams. There is some thinking in non-REM sleep but it is usually simple and fragmented. There are 4 sub-stages to non-REM sleep:
Stage 1 sleep: Is a transition from being awake to being asleep. Is almost worthless in terms of restorative value. Although you may be asleep you may also still be partially conscious.
Stage 2 sleep: Deeper than Stage 1 and is thought to aid in body recovery.
Stages 3 and 4: Also called Delta sleep. Delta sleep is a very deep sleep that is primarily associated with restoration / body recovery.
