Healthy blood flow matters for men because the same blood vessels that supply the heart also supply the penis, and erections depend on blood vessels relaxing and filling with blood. Nitric oxide, made by the lining of blood vessels, signals them to relax. Smoking, high blood pressure, high cholesterol, diabetes, excess weight, inactivity and heavy drinking all damage blood vessels and reduce blood flow, which is why erection problems can be an early sign of heart disease. To support healthy blood flow, exercise regularly, eat plenty of vegetables, fruit, nuts and fish, keep a healthy weight, don't smoke, limit alcohol, manage stress and keep blood pressure, cholesterol and blood sugar in check.
