non-rapid eye movement (NREM) sleep. Stages 3 and 4 NREM sleep. Also called delta or slow wave sleep, these are the deepest levels of human sleep and represent 10-20% of sleep time. They usually occur during the first 30-50% of the sleeping period.

During what cycle of sleep does the body do most of its energy restoration?
The most restorative stage of sleep is NREM-3.In a sleep cycle you progress through the stages:Initial sleep induction: NREM-1 -> NREM-2 -> NREM-3Full sleep cycle: NREM-3 -> NREM-2 -> NREM-1 -> REM -> NREM-1 -> NREM-2 -> NREM-3.A full sleep cycle takes approximately 90 minutes, but the time you spend in each stage changes during the night. At first you spend more time in stage 3, but as your body rests it will spend more and more time in REM.

What is stage 2 nrem?
Stage 2 NREM is a stage of sleep. Adults spend roughly 50% of their time sleeping in this stage. It is characterized by low voltage, mixed frequency EEG with phasic K complexes (waves of 75 microvolts or greater composed of a sharp negative component followed immediately by a sharp positive component, then slowly returning to baseline, over the course of at least 0.5 seconds) and sleep spindles (bursts of synchronous activity in the sigma frequency lasting 0.5 seconds or longer with a visually distinctive morphology resembling a spindle). During Stage 2 sleep, breathing and heart rate are regular and muscles are relaxed. NREM means non-rapid eye movement. The main division of mammalian sleep is into REM and NREM sleep. NREM is further divided into stages 1-4, though the American Academy of Sleep Medicine combined stages 3 and 4 in the 2007 sleep scoring manual.
