If you've been diagnosed with high blood pressure (a systolic pressure -- the top number -- of 140 or above or a diastolic pressure — the bottom number -- of 90 or above), you might be worried about taking medication to bring your numbers down.
Lifestyle plays an important role in treating your high blood pressure. If you successfully control your blood pressure with a healthy lifestyle, you may avoid, delay or reduce the need for medication.
Here are 10 lifestyle changes you can make to lower your blood pressure and keep it down.
1. Lose extra pounds and watch your waistline
Blood pressure often increases as weight increases. Losing just 10 pounds (4.5 kilograms) can help reduce your blood pressure. In general, the more weight you lose, the lower your blood pressure. Losing weight also makes any blood pressure medications you're taking more effective. You and your doctor can determine your target weight and the best way to achieve it.
Besides shedding pounds, you should also keep an eye on your waistline. Carrying too much weight around your waist can put you at greater risk of high blood pressure. In general:
- Men are at risk if their waist measurement is greater than 40 inches (102 centimeters, or cm).
- Women are at risk if their waist measurement is greater than 35 inches (89 cm).
- Asian men are at risk if their waist measurement is greater than 36 inches (91 cm).
- Asian women are at risk if their waist measurement is greater than 32 inches (81 cm).
2. Exercise regularly
Regular physical activity -- at least 30 to 60 minutes most days of the week -- can lower your blood pressure by 4 to 9 millimeters of mercury (mm Hg). And it doesn't take long to see a difference. If you haven't been active, increasing your exercise level can lower your blood pressure within just a few weeks.
If you have prehypertension -- systolic pressure between 120 and 139 or diastolic pressure between 80 and 89 -- exercise can help you avoid developing full-blown hypertension. If you already have hypertension, regular physical activity can bring your blood pressure down to safer levels.
Talk to your doctor about developing an exercise program. Your doctor can help determine whether you need any exercise restrictions. Even moderate activity for 10 minutes at a time, such as walking and light strength training, can help.
But avoid being a "weekend warrior." Trying to squeeze all your exercise in on the weekends to make up for weekday inactivity isn't a good strategy. Those sudden bursts of activity could actually be risky.
3. Eat a healthy diet
Eating a diet that is rich in whole grains, fruits, vegetables and low-fat dairy products and skimps on saturated fat and cholesterol can lower your blood pressure by up to 14 mm Hg. This eating plan is known as the Dietary Approaches to Stop Hypertension (DASH) diet.
It isn't easy to change your eating habits, but with these tips, you can adopt a healthy diet:
- Keep a food diary. Writing down what you eat, even for just a week, can shed surprising light on your true eating habits. Monitor what you eat, how much, when and why.
- Consider boosting potassium. Potassium can lessen the effects of sodium on blood pressure. The best source of potassium is food, such as fruits and vegetables, rather than supplements. Talk to your doctor about the potassium level that's best for you.
- Be a smart shopper. Make a shopping list before heading to the supermarket to avoid picking up junk food. Read food labels when you shop and stick to your healthy-eating plan when you're dining out, too.
- Cut yourself some slack. Although the DASH diet is a lifelong eating guide, it doesn't mean you have to cut out all of the foods you love. It's OK to treat yourself occasionally to foods you wouldn't find on a DASH diet menu, such as a candy bar or mashed potatoes with gravy.
4. Reduce sodium in your diet
Even a small reduction in the sodium in your diet can reduce blood pressure by 2 to 8 mm Hg. The recommendations for reducing sodium are:
- Limit sodium to 2,300 milligrams (mg) a day or less.
- A lower sodium level -- 1,500 mg a day or less -- is appropriate for people 51 years of age or older, and individuals of any age who are African-American or who have high blood pressure, diabetes or chronic kidney disease.
