Which lifestyle factor is a recognized risk factor for heart disease and stroke?

• A. Smoking
• B. Adequate sleep
• C. Regular physical activity
• D. Balanced diet

Answer: (A)

Lifestyle choices that affect heart disease and stroke risk are highly influential. Smoking stands out as a recognized risk factor because it damages the lining of blood vessels, accelerates atherosclerosis, raises blood pressure and heart rate, promotes clotting, and reduces the blood’s oxygen-c carrying capacity. All of these changes elevate the likelihood of heart attack and stroke. By contrast, adequate sleep, regular physical activity, and a balanced diet are associated with lower risk or protective effects on cardiovascular health, not increases in risk. So among the options, smoking is the factor that clearly increases the risk for heart disease and stroke.
