What lifestyle factor is often linked to increased risk for coronary heart disease?

Smoking is a well-established lifestyle factor linked to an increased risk of coronary heart disease. It contributes to the development of atherosclerosis, which is the buildup of plaque in the arteries. This plaque can restrict blood flow and lead to heart attacks and other cardiovascular diseases. The harmful substances in tobacco smoke damage the blood vessels, increase blood pressure, and promote the formation of clots, all of which significantly elevate the risk of heart disease.

Regular physical activity and a balanced diet are protective factors that help maintain cardiovascular health. Engaging in regular exercise can improve heart function, lower blood pressure, and help maintain a healthy weight, while a balanced diet rich in fruits, vegetables, whole grains, and healthy fats can provide essential nutrients that support heart health. Additionally, low stress levels contribute positively to overall health, further reducing the risk of coronary heart disease.

In contrast to the damaging effects of smoking, these other factors promote cardiovascular well-being and are not associated with an increased risk of coronary heart disease.
