Stress can negatively impact physical fitness and body composition by triggering hormonal changes, particularly an increase in cortisol. Elevated cortisol levels can promote fat accumulation, especially in the abdominal area, leading to weight gain. Stress also often results in decreased motivation for exercise, poor dietary choices, and disrupted sleep patterns, all of which can affect physical performance and recovery. Additionally, stress may contribute to muscle tension and fatigue, limiting physical activity levels. Effective stress management techniques, such as mindfulness, yoga, or regular physical activity, can help mitigate these negative impacts.
