What role does Cortisol senken play in Blutzucker?

Cortisol is a stress hormone that promotes gluconeogenesis in the liver and impairs insulin action – both of which raise blood glucose. Chronically elevated cortisol (e.g., due to stress, sleep deprivation, or Cushing's syndrome) can contribute to hyperglycemia and insulin resistance. Lowering cortisol levels (e.g., through stress management, adequate sleep, exercise) may mitigate these effects and improve blood sugar control. The evidence is primarily mechanistic and derived from observational studies; no large randomized trials have proven a causal effect of cortisol reduction on blood glucose in healthy individuals. In people with diabetes or prediabetes, cortisol reduction may be supportive. Important: Lowering cortisol is not a substitute for medical therapy or dietary changes. The reliability of consumer cortisol tests is limited because cortisol fluctuates diurnally and measurements (saliva, hair) only provide snapshots.
