REM Sleep Suppression

Meaning

REM Sleep Suppression is a neurophysiological state characterized by a significant reduction in the duration, frequency, or intensity of the Rapid Eye Movement (REM) stage of sleep, which is the phase predominantly associated with dreaming, memory consolidation, and heightened brain activity. This suppression is often a side effect of certain pharmacological agents, alcohol consumption, or underlying sleep disorders, leading to impaired cognitive function, emotional dysregulation, and a failure to fully complete the essential restorative cycles of sleep.
