Nighttime Growth Hormone Release

Meaning

Nighttime Growth Hormone Release refers to the principal secretory event of somatotropin, a critical anabolic peptide hormone, which typically occurs in pulsatile bursts predominantly during the early stages of slow-wave sleep (SWS). This nocturnal surge is physiologically essential for tissue repair, cellular regeneration, lipolysis, and maintaining lean body mass. A diminished or disrupted nighttime release is a hallmark of somatopause, the age-related decline in growth hormone, and is often linked to poor sleep quality and metabolic dysregulation. Optimizing this release is a key target for anti-aging and recovery protocols.
