Chronic stress can significantly impact physical health by leading to various issues such as high blood pressure and weakened immune function. It affects the body’s hormonal balance, leading to increased cortisol levels, which can contribute to weight gain, digestive issues, and sleep disturbances. Over time, persistent stress may exacerbate conditions like anxiety and depression, thus making it harder to maintain a consistent fitness routine. Stress management techniques like meditation and physical activity are essential for mitigating these effects.
