Physical fitness contributes to longevity by reducing the risk of chronic diseases, improving mental health, and enhancing overall well-being. Regular exercise promotes cardiovascular health, strengthens bones, and boosts the immune system, which can lead to a more active and healthy life. Engaging in physical activity also helps maintain a healthy weight, reduces stress, and improves sleep quality, all of which are vital for extending life expectancy. Furthermore, an active lifestyle supports social connections and mental resilience, fostering a more fulfilling and engaged life. Thus, investing in physical fitness is essential for promoting longevity.
