Cardiovascular fitness improves overall health in various ways. It enhances the efficiency of the heart, lungs, and circulatory system, increasing oxygen delivery to tissues. Improved cardiovascular health can reduce the risk of chronic diseases, such as diabetes and hypertension, and promotes better weight management. In addition, cardiovascular fitness is linked to improved mood and decreased symptoms of depression and anxiety. Engaging in regular aerobic exercise strengthens bones and muscles, ultimately supporting greater longevity and improved quality of life.
