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.

How does REM sleep differ from NREM sleep?

REM sleep, also called rapid-eye movement sleep, is when dreams occur. Our brain is more active during REM, it generates 'smaller and faster brain waves' (Hockenbury 142). The first stage or episode of REM is brief, lasting between 5-15 minutes. NREM sleep (non-rapid-eye-movement, is when brain activity slows down. NREM sleep is grouped in four stages. Stage 1 lasts only a few minutes during which you teeter on the edge of sleep and consciousness. During this stage it is very easy to be woken up by the littlest sounds. During stage 2 breathing becomes rhythmical. Stage 3 and stage 4 of NREM "are often referred to as slow-wave sleep" (Hockenbury 142). Sleepwalking is known to occur during this stage.
