Chronic stress can significantly impair physical fitness by leading to decreased motivation and energy levels, ultimately affecting workout performance. Prolonged stress can result in the elevation of cortisol levels, which may lead to muscle breakdown and fat accumulation. This hormonal imbalance can hinder recovery and result in increased risk of injuries. Chronic stress may also impact sleep quality, crucial for recovery and fitness. Additionally, stress can lead to unhealthy coping mechanisms, like overeating or avoiding exercise, creating a negative cycle that hampers both physical and mental well-being.
