Research has shown that low levels of serotonin, which is a neurotransmitter that plays a role in regulating mood and sleep, are correlated with depression. Serotonin activity inhibits the onset of REM sleep, so people with major depressive disorder may enter REM sleep too early in the night and spend more time in REM due to this dysfunction in serotonin activity.
