Myths vs facts: Cortisol senken and Stress

Cortisol is a key stress hormone, but many claims about simple ways to lower it are exaggerated. Chronic stress can elevate cortisol, which is linked to inflammation (e.g., via IL-1β) and weight gain. However, evidence for supplements or specific diets to reduce cortisol is mostly weak or based on small studies. A hormone test can show levels, but without clinical context results are often misleading. Effective approaches include sleep hygiene, exercise, and stress management – not single 'miracle' products. Genetic tests for cortisol-related genes (e.g., ADRB3) have limited predictive value. Bottom line: many myths, little solid evidence.
