The question of whether lowering cortisol can help with sport requires a nuanced answer. Cortisol is a vital stress hormone that rises acutely during exercise – this is normal and supports energy mobilization. Problems arise only with chronically elevated levels, often due to overtraining, poor sleep, or persistent psychological stress. Chronic high cortisol can promote muscle breakdown, increase fat storage, and impair recovery. Therefore, strategies to lower cortisol – such as adequate sleep, stress management, moderate exercise, and a balanced diet – may indirectly benefit athletic performance and recovery. However, the evidence is mixed: while some studies show that interventions like meditation or certain supplements (e.g., ashwagandha) can reduce cortisol, the effects on specific sports outcomes are often small and highly individual. The provided context lacks direct evidence linking cortisol reduction to improved sport performance. Thus, a blanket recommendation to lower cortisol for all athletes is not supported. Instead, a holistic approach focusing on overall stress regulation and lifestyle is advisable. If an imbalance is suspected, medical consultation is recommended.
