Growth Hormone and Sleep

Meaning

Growth Hormone and Sleep describes the essential, highly regulated physiological relationship where the majority of endogenous Human Growth Hormone (HGH) secretion occurs in a pulsatile manner, predominantly during the deep, slow-wave stages of sleep. This nocturnal surge of HGH is critical for anabolic processes, including tissue repair, muscle protein synthesis, lipolysis, and maintaining metabolic homeostasis. Disrupted sleep architecture directly impairs this hormonal release, negatively impacting recovery and body composition.
