You take your heart for granted. It's probably time you showed it a little gratitude, says Dr Mehmet Oz.
1 Push yourself. As long as you don't have any existing problems with your heart, you can and should regularly push its limits. Several times a week, sprint at full speed until your heart is pounding. Over time, your heart will slow down at rest and its pumping will become more efficient.
2 Get some sun. Or at least vitamin D: your risk of hypertension skyrockets
if you're deficient in vitamin D, and hypertension makes it harder for your heart to pump blood. In the summer, getting the vitamin is easy, because it comes from the sun. But during a British winter you need a boost. Try 1,000 IU daily supplements.
3 Up your omega-3 fats. Three reasons to take this supplement every morning, as I do (seriously, come over any morning and I'll show you): they clean out the arteries that supply your heart with the oxygen it needs; they lower your blood pressure, making it easier for your heart to pump blood, and they may prevent arrhythmias (misfires of the heart's electrical system).
4 Have more sex. The next time she's tired or has a headache, tell her this: having sex twice or more per week will cut your risk of a heart attack in half. She will literally be saving your life.
