Quizplus · Accepted Answer

Emotional arousal, blood pressure changes, and sexual arousal primarily occur during REM (rapid eye movement) sleep. This is because REM sleep is associated with heightened brain activity and vivid dreams, which can trigger emotional responses and physiological changes. In contrast, NREM (non-rapid eye movement) sleep is generally characterized by lower levels of brain activity and little to no emotional or physiological arousal. Delta sleep and Stage 4 sleep are both types of NREM sleep, and are associated with deep, restorative sleep rather than arousal or activity.
