Detailed explanation-1: -Stage 1 sleep is a transitional phase that occurs between wakefulness and sleep, the period during which we drift off to sleep. During this time, there is a slowdown in both the rates of respiration and heartbeat.
Detailed explanation-2: -Sleep Stages Stage 1 non-REM sleep is the changeover from wakefulness to sleep. During this short period (lasting several minutes) of relatively light sleep, your heartbeat, breathing, and eye movements slow, and your muscles relax with occasional twitches.
Detailed explanation-3: -Stage 1. Stage 1, also called N1, is essentially when a person first falls asleep. This stage normally lasts just one to seven minutes. During N1 sleep, the body has not fully relaxed, though the body and brain activities start to slow with periods of brief movements.
Detailed explanation-4: -SWS, or delta sleep, follows stage 2 sleep and is characterized by polymorphic, semirhythmic delta waves accounting for at least 20% of the EEG activity. SWS is characterized by relative body immobility. SWS is maximal in young children and markedly decreases with age.
Detailed explanation-5: -Stage 1. Stage 1 NREM sleep is the first sleep stage you enter when nodding off. This sleep stage is when heartbeat, eye movements, brain waves, and breathing activity begin to taper down. Motor movements also diminish, although you may experience muscle twitches called hypnic jerks.
