Emotions are more apparent in stages of REM-sleep rather than other stages of sleep. It was found that during REM-sleep negative emotions diminish. After going through stages of REM-sleep, people with depression report feeling better, in a study done by Cartwright et al. 1 . Conversely, a theory proposed by Revonsuo 2 states that when people experience negative emotions or negative events, when they sleep the REM-sleep replays such events, which is known as rehearsal. During REM-sleep areas of the brain, the suborbital area, and the cortical area are responsible for emotion but also a suppression of arousing emotions are activated. Scientists noticed a decrease in the hormone noradrenaline which is released into the body after a highly stimulating event. People reported trouble falling asleep or sleeping consistently throughout the night when a stressful event was happening in their life, as observed by Åkerstedt 3 . REM-sleep aids people with negative emotion or high stress.
