Which lifestyle change can significantly contribute to lowering the risk of coronary heart disease?

Regular physical activity plays a crucial role in lowering the risk of coronary heart disease. Engaging in consistent exercise helps improve cardiovascular health by strengthening the heart muscle, improving blood circulation, and lowering blood pressure. Physical activity also aids in maintaining a healthy weight and can improve cholesterol levels. These factors reduce the strain on the heart and decrease the risk of developing heart disease.

Incorporating regular physical activity into one's lifestyle can help manage stress, improve mood, and increase overall energy levels, further contributing to a healthier heart. The cumulative benefits of an active lifestyle are well-supported by research, highlighting its importance in heart disease prevention.

Other options, such as increasing sodium intake, managing stress (while beneficial in moderation), and limiting sleep, do not have the same protective effects against coronary heart disease and may even contribute to increased risk factors associated with heart health.
