The evidence is more nuanced: Cortisol is essential for fetal lung maturation and helps initiate labor via placental CRH signaling. Some observational studies link high maternal cortisol to increased preterm birth risk, but effect sizes are small and confounded by genetics, socioeconomic factors, and sleep. Causality remains unclear because stress is multifactorial and cortisol fluctuates diurnally. Systematic reviews conclude that cortisol alone is not a reliable predictor of labor onset. The evidence is primarily mechanistic and observational, not strong enough for clinical recommendations. Direct-to-consumer genetic tests for cortisol-related genes (e.g., CRH, NR3C1) currently lack validated utility for predicting labor timing.","area":"gesundheit","canonical_id":"gesundheit:canonical-ae37f44b690f22720f9b9d27","id":"public-12233563845cde71209365b7","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Lay opinion vs evidence: Cortisol Labor","score":38.28325476,"snippet":"Lay opinion often claims that stress—and thus elevated cortisol—can trigger early labor.
