Circadian Rhythm Stability

Meaning

Circadian rhythm stability denotes the consistent, predictable synchronization of the body’s approximately 24-hour internal biological clock with the external light-dark cycle. This rhythmic oscillation governs nearly all physiological processes, including sleep-wake cycles, hormone secretion patterns, and metabolic rate, thereby acting as a master regulator of systemic homeostasis. Clinical focus on stability ensures that hormonal peaks and troughs, such as cortisol and melatonin, occur at their appropriate phases and amplitudes.
