Slow Wave Secretion

Meaning

Slow Wave Secretion is a term used to describe the critical neuroendocrine phenomenon where the deep stages of Non-Rapid Eye Movement (NREM) sleep, characterized by high-amplitude, slow-frequency delta waves, are temporally coupled with the maximal pulsatile release of Growth Hormone (GH). This synchronized secretion is essential for the overnight repair and regeneration of musculoskeletal tissue, the mobilization of fat stores for energy, and the overall maintenance of a youthful metabolic profile. Impairment in the slow wave phase directly diminishes this crucial anabolic hormone pulse, contributing to age-related sarcopenia and metabolic inefficiency.
