What role does Cortisol senken play in Allergie?

The question about the role of lowering cortisol in allergies cannot be directly answered from the provided context, which focuses on pharmacogenetics, MTHFR, ACTN3, and other topics. Generally, cortisol is a stress hormone with immunomodulatory properties. Chronically elevated cortisol levels can exacerbate allergic reactions by influencing inflammatory processes. Lowering cortisol could therefore theoretically have anti-inflammatory effects. However, the evidence is complex: cortisol has both anti-inflammatory and pro-inflammatory effects depending on dose, duration, and individual physiology. There are no robust clinical trials demonstrating cortisol reduction as a specific therapy for allergies. Moreover, measures to reduce cortisol (e.g., stress management, sleep optimization) may be generally health-promoting but are not recommended as direct allergy treatment. Patients should not attempt hormonal interventions on their own. The evidence is rated as 'unclear', based on mechanistic considerations without strong human studies from the given context.
