Invisible and virtually impossible to feel, high blood pressure is quietly ravaging the blood vessels, heart muscles and kidneys of more than 80 million North Americans. Another 70 million of you are at high risk for developing HBP because of your weight, diet or blood sugar (prediabetes).
But theres a lot you can do to control or prevent HBP and all that it can trigger.
If youre still trying to get your blood pressure under control or you want to keep it there, five smart steps can help you do it. And if youre taking blood-pressure meds, adding these strategies can help them work better, allow your doctor to adjust your dose and definitely add new levels of protection for your heart, brain, eyes, kidneys, bones and reproductive organs. We recommend aiming for a blood pressure reading of 115/75.
1. Do daily home pressure checks (more if your doc says so). Using a home blood-pressure monitor regularly can keep you motivated, lower your blood pressure, ID problems quickly and help your doctor keep medication levels right. Thats enough to cut your risk for an HBP-related fatal heart attack and stroke. So, keep track of daily readings (print out a handy chart or use online tools at the American Heart Associations website, www.heart.org) so you can share the numbers with your doctor.
2. Take three 10-minute walks a day. We have long advocated walking 10,000 steps a day for overall great health. Physical activity helps keep arteries flexible, a natural route to lower pressure. But new reports show that for people at risk for high blood pressure, striding out for three 10-minute walks (right after meals is the best if your doc agrees) keeps arteries just as flexible and blood pressure just as low as one 30-minute walk. Make sure that even if youre pressed for time, you get in multiple 10-15 minute walks. If you already have HBP, work with your doctor to determine your safe level of activity.
3. Control your waist size, too. Staying waist-trim means youre carting around less deep abdominal fat, which boosts blood pressure. A waist measuring more than 34 1/2 inches doubles a womans odds for high blood pressure; for guys, a middle over 40 inches boosts the risk of HBP fivefold. Already have HBP? Shrinking your waist size also means youve reduced fat inside your kidney capsule (that fat goes first), which helps normalize blood pressure.
4. Aim for a healthy intake of potassium to sodium. Most of us take in about one-third more salt than we should. That pulls more fluid into the bloodstream and interferes with your blood pressures daily rhythms. It reduces your normal, nighttime BP dip that gives your heart a breather and pumps up the normal BP rise that happens before you wake up, boosting odds for early a.m. heart attack or stroke. We suggest you aim for a cap of 1,500 mg of salt a day, or 1/2 to 3/4 teaspoon.
At the same time, boost potassium with plenty of greens and fruits, like bananas, peaches and berries. This mineral helps your body excrete excess sodium and relaxes arteries, too. Aim for 3,500 mg of potassium a day.
5. Give yourself at least 10 minutes of stress control daily. Try progressive muscle relaxation, a breathing routine, meditation, yoga or other serene strategy. When stress turns on your bodys fight-or-flight response, adrenal hormones boost your heart rate and blood pressure. When you say, "Ommm," youll feel better all over.
