Myths vs facts: Cortisol senken and Langlebigkeit

Cortisol is a vital hormone that, in moderation, protects the body. Chronically elevated levels due to prolonged stress can promote inflammation, disrupt sleep, and shorten telomeres – factors linked to accelerated aging. However, the idea that deliberately lowering cortisol extends lifespan is not supported by robust clinical trials. Myth: Cortisol is always bad. Fact: Acute cortisol release is essential for survival; only chronic elevation is problematic. Myth: Supplements like ashwagandha or phosphatidylserine reliably lower cortisol and prolong life. Fact: Evidence is weak to moderate; effects are small and not tested for longevity. Proven strategies include adequate sleep, regular exercise, mindfulness, and social connection. Direct causality between cortisol reduction and human longevity is unproven. Home cortisol tests have limited reliability due to high variability. Bottom line: Stress management is beneficial, but cortisol is just one piece of the longevity puzzle.
