Stress can negatively impact physical health and fitness by promoting unhealthy behaviors and affecting bodily functions. Chronic stress often leads to overeating or unhealthy food choices, decreasing nutritional quality. Furthermore, stress may disrupt sleep patterns, impairing recovery and overall performance. Elevated stress levels can also increase the risk of injury during workouts due to reduced focus. Adopting stress management techniques, such as mindfulness or exercise, can mitigate these effects, promoting a healthier lifestyle and improving physical fitness outcomes.
