REM Cycle Hormones

Meaning

REM Cycle Hormones refers to the specific set of endocrine signals whose secretion patterns are dynamically altered or critically regulated during the Rapid Eye Movement (REM) phase of sleep, which is characterized by vivid dreaming and high brain activity. Unlike the deep sleep phase where Growth Hormone peaks, REM sleep is associated with distinct changes in the pulsatile release of hormones like cortisol, prolactin, and melatonin. The integrity of the REM cycle is essential for neuroendocrine health, as it facilitates emotional processing, memory consolidation, and the final stages of the body’s nightly hormonal reset. Disruptions in this phase directly compromise mental and metabolic health.
