Hormone Secretion Chronobiology

Meaning

Hormone Secretion Chronobiology is the scientific study of the temporal organization and rhythmic patterns of hormone release from the endocrine glands, specifically focusing on the influence of the body’s internal circadian clock. This field investigates the predictable, 24-hour, and other cyclical variations in hormones like cortisol, melatonin, and sex steroids, recognizing that timing is crucial to their biological effect. Optimal health relies on the precise synchronization of these hormonal rhythms with the external light-dark cycle. Dysregulation compromises systemic homeostasis.
