What role does Cortisol senken play in blood sugar?

Cortisol is a stress hormone that raises blood sugar via gluconeogenesis and insulin resistance. Lowering cortisol (e.g., through stress management, sleep optimization, or supplements like ashwagandha) can therefore indirectly reduce blood sugar, especially in chronic stress or conditions like Cushing's syndrome. Evidence for a significant blood sugar reduction from cortisol lowering in healthy individuals is moderate—most studies show small effects. Important: cortisol measurements (e.g., saliva tests) have strong diurnal variation and are not diagnostic. Persistent high fasting glucose should be evaluated by a doctor. MyBody-X tests on stress and metabolism provide clues, not medical diagnosis.
