If you’ve been diagnosed with high blood pressure, 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 might 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.

Lose extra pounds

Blood pressure often increases as weight increases. Being overweight also can cause disrupted breathing while you sleep (sleep apnea), which further raises your blood pressure.

Weight loss is one of the most effective lifestyle changes for controlling blood pressure. Losing even a small amount of weight if you’re overweight or obese can help reduce your blood pressure.

Besides shedding pounds, you generally 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.

Exercise regularly

Regular physical activity — such as 150 minutes a week, or about 30 minutes most days of the week — can lower your blood pressure by about 5 to 8 mm Hg if you have high blood pressure. It’s important to be consistent because if you stop exercising, your blood pressure can rise again.

If you have elevated blood pressure, exercise can help you avoid developing hypertension. If you already have hypertension, regular physical activity can bring your blood pressure down to safer levels.

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 11 mm Hg if you have high blood pressure. This eating plan is known as the Dietary Approaches to Stop Hypertension (DASH) diet.

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.

Reduce sodium in your diet

Even a small reduction in the sodium in your diet can improve your heart health and reduce blood pressure by about 5 to 6 mm Hg if you have high blood pressure.

The effect of sodium intake on blood pressure varies among groups of people. In general, limit sodium to 2,300 milligrams (mg) a day or less. However, a lower sodium intake — 1,500 mg a day or less — is ideal for most adults.

Cut back on caffeine

The role caffeine plays in blood pressure is still debated. Caffeine can raise blood pressure up to 10 mm Hg in people who rarely consume it. But people who drink coffee regularly may experience little or no effect on their blood pressure.

Although the long-term effects of caffeine on blood pressure aren’t clear, it’s possible blood pressure may slightly increase.

Limit alcohol

Alcohol can be both good and bad for your health. By drinking alcohol only in moderation — generally one drink a day for women, or two a day for men — you can potentially lower your blood pressure by about 4 mm Hg. One drink equals 12 ounces of beer, five ounces of wine or 1.5 ounces of 80-proof liquor.

Drinking more than moderate amounts of alcohol can actually raise blood pressure. It can also reduce the effectiveness of blood pressure medications.

Quit smoking

Each cigarette you smoke increases your blood pressure for many minutes after you finish. Stopping smoking helps your blood pressure return to normal. Quitting smoking can reduce your risk of heart disease and improve your overall health. People who quit smoking may live longer than people who never quit smoking.

Reduce your stress

Chronic stress may contribute to high blood pressure. More research is needed to determine the effects of chronic stress on blood pressure. Occasional stress also can contribute to high blood pressure if you react to stress by eating unhealthy food, drinking alcohol or smoking.

Take some time to think about what causes you to feel stressed, such as work, family, finances or illness. Once you know what’s causing your stress, consider how you can eliminate or reduce stress.

Monitor at home

Home monitoring can help you keep tabs on your blood pressure, make certain your lifestyle changes are working, and alert you and your doctor to potential health complications. Blood pressure monitors are available widely and without a prescription. Talk to your doctor about home monitoring before you get started.

Regular visits with your doctor are also key to controlling your blood pressure.

Get support

Supportive family and friends can help improve your health. They may encourage you to take care of yourself, drive you to the doctor’s office or embark on an exercise program with you to keep your blood pressure low.

If you find you need support beyond your family and friends, consider joining a support group. This may put you in touch with people who can give you an emotional or morale boost and who can offer practical tips to cope with your condition.
