Hormonal Chronometry

Meaning

Hormonal Chronometry is the scientific study and clinical application of the precise timing and rhythmic patterns of hormone secretion and action, particularly the circadian and ultradian rhythms that govern endocrine function. This discipline recognizes that the biological effect of a hormone is not solely dependent on its concentration but also critically dependent on when it is released or administered relative to the body’s internal biological clock. Clinical strategies utilizing chronometry aim to optimize treatment efficacy and minimize side effects by aligning therapeutic dosing with the body’s natural endocrine pulsatility and diurnal fluctuations. Understanding this timing is essential for truly personalized hormonal health.
