Stage 2, NREM sleep: More rehashed sleep cycles are spent in this phase than in other stages. This is a period of light sleep, before entering a deeper sleep. Heartbeat and breathing lull, muscles loosen up further, eyes quit moving, and body temperature falls. Cerebrum movement eases back yet with infrequent blasts of action.

 

Stage 3, NREM sleep: This deep sleep time is expected to feel invigorated during the day. Longer times of deep sleep will in general happen in the principal half of the night. Heartbeat and breathing rates are the slowest while asleep here, and mind action backs right off, and muscles are loose.
