REM Sleep Chemistry

Meaning

REM Sleep Chemistry refers to the unique and dynamic neurochemical milieu that characterizes the Rapid Eye Movement (REM) stage of sleep, which is critical for memory consolidation, emotional regulation, and neuroplasticity. This phase is distinguished by high levels of acetylcholine, promoting cortical activation, coupled with near-total suppression of monoamines, such as norepinephrine, serotonin, and histamine, which results in muscle atonia. The precise balance of these neurotransmitters is essential for the quality and duration of REM sleep, directly impacting the brain’s ability to process emotional information and reset neuroendocrine signaling pathways.
