[sidebar] 1. Get a heart check"Make a doctor’s appointment as soon as you notice that you’re having trouble getting or maintaining an erection," says Dr. Banks. “Your doctor should check your blood pressure, blood glucose, and blood cholesterol and discuss your diet and physical activity levels.” If not, speak up. 2. Be nice to your bodyThe same behaviors will improve both heart and sexual health. “Aim for at least 30 minutes of moderate physical activity per day, like brisk walking,” says Dr. Banks. “Consume foods low in sodium (avoid these six hidden salt bombs!), saturated and trans fats, and sugar. This means eating whole grains, lean protein, and colorful produce.” 3. Stress lessIf you’re feeling frazzled, experiment with a stress-reduction technique such as meditation or exercise. Stress hormones—cortisol and adrenaline—can decrease libido and constrict blood vessels, including those that allow you to get an erection. Chronic stress also can increase blood pressure and may damage artery walls. (Give these three effective stress-busters a try.) More from Prevention: How To Want Sex Again
