Detailed explanation-1: -Stage 2: This period of light sleep features periods of muscle tone (muscles partially contracting) mixed with periods of muscle relaxation. Your eye movement stops, heart rate slows and body temperature decreases. Brain waves become slower.
Detailed explanation-2: -Stage 2. Stage 2 NREM sleep sees a continued slowing of heartbeat, breathing, muscle activity, and eye movements. During this stage, you also experience a reduction in body temperature. Throughout the course of the night, you spend about half the time in stage 2 sleep.
Detailed explanation-3: -During REM sleep, your eyes move around rapidly in a range of directions, but don’t send any visual information to your brain. That doesn’t happen during non-REM sleep. First comes non-REM sleep, followed by a shorter period of REM sleep, and then the cycle starts over again. Dreams typically happen during REM sleep.
Detailed explanation-4: -Why Is Non-REM Sleep Important? Non-REM sleep is just as important as the REM stage of sleep but contributes to your health differently. NREM sleep helps your body wind down and fall into a deep sleep, which helps you feel more rested in the morning.
Detailed explanation-5: -Typically, sleep begins with a NREM sleep stage, cycles through the three NREM stages, and is followed by a REM period. Throughout the night, NREM and REM sleep alternate in a cyclical fashion, over approximately 90 minutes with REM sleep periods getting progressively longer.
