9 Myths About the ‘Stress Hormone’ Cortisol

“Cortisol detox” protocols circulate widely online. Some center on specific foods; others on morning routines, sleep hygiene, and screen time. Yet the concept of detoxing a hormone that your body produces continuously, and regulates through a tightly controlled system, doesn’t hold up to scrutiny, experts say.

Direct-to-consumer cortisol testing has exploded alongside the at-home medical testing market. Saliva kits, urine strips, and even hair follicle analysis claim to reveal whether your cortisol is out of range—but experts urge caution.
