Stress hormones, particularly cortisol, can negatively impact physical performance by affecting energy levels and muscle recovery. Elevated cortisol can lead to fatigue, decreased muscle mass, and hindered recovery from workouts. It may increase the perception of effort during exercise, making workouts feel more challenging. Chronic stress may also lead to poor nutrition choices, further impacting performance negatively. Managing stress through relaxation techniques, adequate sleep, and balanced training can help mitigate these effects, promoting better physical outcomes and overall wellness.
