Regular physical activity significantly contributes to heart health by improving cardiovascular function, reducing blood pressure, and enhancing circulation. Engaging in aerobic exercises strengthens the heart muscle, making it more efficient in pumping blood. Additionally, regular activity helps maintain healthy cholesterol levels by increasing HDL cholesterol and decreasing LDL cholesterol. It also facilitates better weight management, reducing the risk of conditions like heart disease and stroke. Importantly, consistent exercise has been shown to lower stress levels, further contributing to overall cardiovascular health.
