Cortisol stress hormone health impact

Recent health briefs explain how cortisol, the body’s primary stress hormone, follows a natural daily rhythm that peaks 30–45 minutes after waking to boost alertness and provide energy. Disruption of this cycle by chronic stress keeps cortisol elevated, leading to fatigue, sleep difficulties, weight gain—particularly abdominal—and cravings for sugary foods, as well as skin thinning, high blood pressure and headaches.

Experts note that persistent high cortisol also influences insulin levels, promoting visceral fat storage and impairing metabolism. Nutritionists and physicians emphasize that balanced cortisol supports focus, memory, immune response and anti‑inflammatory functions. To restore a healthy cortisol pattern, they recommend consistent high‑quality sleep, regular moderate exercise, stress‑reduction practices such as meditation or yoga, and a balanced diet while limiting stimulants like caffeine, alcohol and nicotine.
