PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -The first stage of NREM sleep is known as stage 1 sleep. 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: -Stage 1 Non-REM (Rapid Eye Movement) Sleep Stage 1 kicks off the sleep cycle, as we transition from wakefulness to a light sleep. This first stage is when you’re just drifting off to slumber. Your heartbeat, eye movements, and breathing slow down; your muscles relax; and your brain activity begins to taper off.

Detailed explanation-3: -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.

Detailed explanation-4: -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-5: -NREM STAGES OF SLEEP In addition, stage 1 sleep involves a marked decrease in both overall muscle tension and core body temperature. In terms of brain wave activity, stage 1 sleep is associated with both alpha and theta waves.
