What role does regular exercise play in preventing chronic diseases?

• A. It helps build muscle strength
• B. It maintains a healthy weight and strengthens the heart
• C. It increases flexibility and balance
• D. It reduces sleep disturbances

Answer: (B)

Regular exercise plays a significant role in preventing chronic diseases primarily by maintaining a healthy weight and strengthening the heart. Engaging in physical activity helps to regulate body weight by burning calories, which is vital for energy balance and preventing obesity—a major risk factor for various chronic diseases such as diabetes, heart disease, and certain cancers. Moreover, exercise strengthens the heart by improving cardiovascular health. It enhances blood circulation, lowers blood pressure, improves cholesterol levels, and increases the efficiency of the heart and lungs. These cardiovascular benefits are essential in reducing the risk of developing heart disease, one of the leading causes of morbidity and mortality globally. While building muscle strength, increasing flexibility and balance, and reducing sleep disturbances are important benefits of regular exercise, they are secondary in the context of chronic disease prevention. The key impact of regular exercise lies in its ability to promote a healthy body weight and optimize heart function, directly addressing the primary factors that contribute to the development of chronic conditions.
