AP PSYCHOLOGY

Detailed explanation-1: -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-2: -Sleepwalking happens during non-REM (NREM) sleep, usually in stage III of the sleep cycle, which is also known as deep sleep.

Detailed explanation-3: -Stage 4: REM sleep In REM sleep, your brain waves and eye movements increase. Your heart rate and breathing also speed up. Dreaming often happens during REM sleep. Your brain also processes information during this stage, making it important for learning and memory.

Detailed explanation-4: -Electroencephalography. These four sleep stages are called non-rapid eye movement (non-REM) sleep, and its most prominent feature is the slow-wave (stage IV) sleep. It is most difficult to awaken people from slow-wave sleep; hence it is considered to be the deepest stage of sleep.

Detailed explanation-5: -Stage 4-REM Sleep The first round of REM in a night lasts about 10 minutes, with the stage getting longer and longer each time you enter REM in one night1. It’s also the deepest stage of sleep, where you’ll experience1: Quickened breathing. Faster heart rate and blood pressure.
