What role does Cortisol senken play in allergy?

The role of lowering cortisol in allergy is nuanced. Cortisol is a stress hormone with potent anti-inflammatory effects; acutely, it suppresses histamine release and allergic inflammation. This is why corticosteroids are used to treat allergic conditions. Lowering cortisol chronically (e.g., via stress reduction) might theoretically reduce the body's anti-inflammatory capacity, potentially worsening allergies. However, evidence is limited and mixed: some studies link chronic stress to allergy exacerbation, but this is mediated by immune dysregulation rather than cortisol levels alone. There is no strong evidence that deliberately lowering cortisol improves allergy symptoms. In fact, low cortisol states (e.g., adrenal insufficiency) can increase sensitivity to allergens. Consumer tests claiming to measure cortisol are often unreliable. The best evidence supports stress management for overall health, not specifically for cortisol reduction in allergy. Clinical guidelines do not recommend targeting cortisol for allergy treatment. Evidence: mechanistic/weak. Caveat: do not confuse therapeutic corticosteroids (which raise cortisol activity) with lowering endogenous cortisol.
