Adrenal Hormone Cycling

Meaning

The rhythmic, predictable fluctuation of hormones produced by the adrenal glands, primarily glucocorticoids like cortisol, over a 24-hour period. This cycling is a fundamental aspect of the body’s circadian system, essential for maintaining homeostasis and coordinating various physiological functions. Clinically, assessing this temporal pattern, rather than relying on a single point measurement, provides crucial insight into adrenal function and the body’s stress adaptation capacity.
