Have you been feeling a little lonely lately? Then do something about it. Right now. Really. Call an old friend. Get together. Join a message board. Volunteer. Otherwise, your heart could pay the price. Because the lonelier people feel, the higher their blood pressure may rise. According to a recent study, loneliness seems to affect systolic blood pressure most. That’s the top number in your blood pressure reading, and too-high systolic readings can increase your risk of stroke or heart disease. So get connected! Your heart will be lighter and healthier for it. Other ways to lower your pressure include cutting sodium in your diet, working out, trimming down, and not sweating the small stuff.
