Physical activity significantly improves cardiovascular health by strengthening the heart muscle and enhancing circulation. Regular exercise increases heart rate, promoting the efficient pumping of blood throughout the body. This process supports better oxygen delivery to tissues, aids in controlling blood pressure, and helps maintain healthy cholesterol levels. Additionally, it reduces inflammation and improves insulin sensitivity, further lowering the risk of heart disease. Engaging in moderate to vigorous activities can also help regulate body weight, decreases the likelihood of developing chronic diseases, and improves overall well-being.
