Chronically elevated cortisol – due to persistent stress, poor sleep, or inflammation – is associated with accelerated biological aging, increased insulin resistance, and cognitive decline. Epidemiological studies link high cortisol levels to shortened telomere length and higher all-cause mortality. However, no randomized controlled trials have proven that lowering cortisol directly extends lifespan. Interventions such as stress reduction (mindfulness, yoga), adequate sleep, moderate exercise, and anti-inflammatory diets can modestly reduce cortisol. Supplements like ashwagandha or phosphatidylserine show small effects in short-term studies but are not approved longevity drugs. Importantly, cortisol is an essential hormone; excessive lowering can be dangerous (adrenal insufficiency). Consumer DNA tests for cortisol-related genes (e.g., NR3C1, FKBP5) provide only weak clues and do not replace clinical assessment. Evidence grade: human-moderate (observational) to mixed (interventions). Conclusion: Managing cortisol is sensible for healthy aging, but it is not a guaranteed path to longevity.","area":"gesundheit","canonical_id":"gesundheit:canonical-4747e3c2645528fffe9d519b","id":"public-632e06a0d4c70f79329624e1","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Cortisol senken in the context of Langlebigkeit","score":18.96575255,"snippet":"The question of whether lowering cortisol promotes longevity is scientifically relevant, but the evidence requires careful interpretation.
