Which of the following is a benefit of regular physical activity?

Regular physical activity is associated with a multitude of health benefits, one of which is improved cardiovascular health. Engaging in physical activities strengthens the heart muscle, enhances blood circulation, and increases the efficiency of the cardiovascular system. This improvement can lead to lower resting heart rates, better blood pressure control, and a reduced risk of heart disease and stroke. By regularly incorporating physical activity into one’s routine, individuals can experience significant benefits that contribute to overall cardiovascular function and health.

In contrast, the other options provided do not reflect the positive effects of regular exercise. Increased risk of chronic diseases contradicts the well-documented benefits of physical activity, which actually reduces this risk. Similarly, while physical activity is known to enhance sleep quality, which is mentioned in another option, the focus here is on cardiovascular health specifically. Lastly, regular exercise tends to increase energy levels rather than decrease them, making that option incorrect as well.
