What role does Cortisol senken play in Müdigkeit?

The role of lowering cortisol in fatigue cannot be directly answered from the provided context. Cortisol is a key stress hormone that regulates energy metabolism. Chronically elevated cortisol (e.g., from ongoing stress) can contribute to fatigue, and reducing it may help. However, fatigue is multifactorial—poor sleep, nutritional deficiencies, thyroid issues, or psychological factors are often more relevant. Moreover, abnormally low cortisol (adrenal insufficiency) can also cause fatigue. Without individual diagnostics (e.g., salivary cortisol day curve), blanket recommendations to lower cortisol are not evidence-based. The evidence is mixed: for stressed but otherwise healthy individuals, stress reduction techniques (mindfulness, sleep hygiene) moderately lower cortisol and may improve fatigue. Direct pharmacological or supplement-based cortisol lowering should only be done under medical supervision. In summary, the link between cortisol reduction and fatigue is context-dependent and requires personalized assessment.
