Physical activity significantly impacts longevity by reducing the risk of various chronic diseases, such as heart disease and diabetes. Engaging in regular exercise promotes cardiovascular health and strengthens the immune system. Physical activity also enhances mental well-being by releasing endorphins, which can contribute to better mood and reduced stress. Moreover, active individuals often display healthier habits, such as balanced nutrition and avoidance of smoking, which further support a longer, healthier life. Overall, maintaining an active lifestyle is essential for promoting a longer lifespan and overall wellness.
