What role does Cortisol senken play in fatigue?

The role of lowering cortisol in fatigue is nuanced. Cortisol is a key stress hormone; chronically elevated levels can disrupt sleep, increase inflammation, and lead to adrenal dysregulation, contributing to fatigue. In such cases, interventions that lower cortisol – like stress reduction, regular exercise, sleep hygiene, or adaptogens (e.g., ashwagandha) – may improve energy. However, fatigue is a multifactorial symptom; low cortisol (adrenal insufficiency) also causes profound tiredness. Without objective cortisol measurement, blanket recommendations to lower cortisol are not evidence-based. The provided knowledge context lacks direct studies or genetic markers linking cortisol reduction to fatigue relief. While SNPs in COMT or TNF might influence stress response, their effect on cortisol is indirect and small. Evidence grade: unclear. Caveat: Do not self-treat fatigue with cortisol-lowering supplements without medical guidance. A proper workup (blood/salivary cortisol, thyroid, iron, etc.) is essential. Sources: none from context.
