What is one way exercise can improve longevity?

Exercise significantly contributes to longevity primarily by decreasing the risk of chronic diseases. Engaging in regular physical activity has been shown to improve cardiovascular health, enhance metabolic function, and strengthen the immune system, all of which can lead to a lower incidence of diseases such as heart disease, diabetes, and certain cancers.

Moreover, exercise helps manage blood pressure, improves cholesterol levels, and helps in maintaining a healthy weight—all of which are crucial factors in reducing disease risk. This multifaceted impact of exercise on overall health directly correlates with improved life expectancy and a better quality of life as individuals age. Thus, the association between exercise and a reduced risk of chronic diseases is a key aspect of how it promotes longevity.
