AP PSYCHOLOGY

Detailed explanation-1: -Sleepwalking happens during non-REM (NREM) sleep, usually in stage III of the sleep cycle, which is also known as deep sleep. Along with other parasomnias like sleep talking, confusional arousals, and sleep terrors, sleepwalking is classified as an NREM disorder of arousal.

Detailed explanation-2: -Stage 3 sleep is also known as N3 or deep sleep, and it is harder to wake someone up if they are in this phase. Muscle tone, pulse, and breathing rate decrease in N3 sleep as the body relaxes even further. The brain activity during this period has an identifiable pattern of what are known as delta waves.

Detailed explanation-3: -Sleepwalking (somnambulism) most often occurs during deep, non-REM sleep (called N3 sleep) early in the night. Sleepwalking is much more common in children and young adults than in older adults. This is because as people age, they have less N3 sleep. Sleepwalking tends to run in families.

Detailed explanation-4: -During this stage, your muscles become more relaxed and you may begin to have slow-wave (delta) brain activity. Stage N3 is deep sleep and lasts about 20 to 40 minutes. During this stage, delta brain activity increases and you may have some body movements. It is very hard to wake up someone in stage N3.

Detailed explanation-5: -By stage 3 you are in a deep sleep. Stage 4 REM, known as paradoxical sleep, is when the body’s immobilized and dreams occur. Each sleep stage has a unique function and role in maintaining your brain’s overall cognitive performance.
