Get StartedLifestyle and home remedies
By Mayo Clinic staffLifestyle changes can help you control and prevent high blood pressure — even if you're taking blood pressure medication. Here's what you can do:
- Eat healthy foods. Try the Dietary Approaches to Stop Hypertension (DASH) diet, which emphasizes fruits, vegetables, whole grains and low-fat dairy foods. Get plenty of potassium, which can help prevent and control high blood pressure. Eat less saturated fat and total fat.
- Decrease the salt in your diet. Although 2,400 milligrams (mg) of sodium a day is the current limit for otherwise healthy adults, limiting sodium intake to 1,500 mg a day will have a more dramatic effect on your blood pressure. While you can reduce the amount of salt you eat by putting down the saltshaker, you should also pay attention to the amount of salt that's in the processed foods you eat, such as canned soups or frozen dinners.
- Maintain a healthy weight. If you're overweight, losing even 5 pounds (2.3 kilograms) can lower your blood pressure.
- Increase physical activity. Regular physical activity can help lower your blood pressure and keep your weight under control. Strive for at least 30 minutes of physical activity a day.
- Limit alcohol. Even if you're healthy, alcohol can raise your blood pressure. If you choose to drink alcohol, do so in moderation — up to one drink a day for women and everyone over age 65, and two drinks a day for men.
- Don't smoke. Tobacco injures blood vessel walls and speeds up the process of hardening of the arteries. If you smoke, ask your doctor to help you quit.
- Manage stress. Reduce stress as much as possible. Practice healthy coping techniques, such as muscle relaxation and deep breathing. Getting plenty of sleep can help, too.
- Monitor your blood pressure at home. Home blood pressure monitoring can help you keep closer tabs on your blood pressure, show if medication is working, and even alert you and your doctor to potential complications. If your blood pressure is under control, you may be able to make fewer visits to your doctor if you monitor your blood pressure at home.
- Practice relaxation or slow, deep breathing. Do it on your own or try device-guided paced breathing. In some clinical trials, regular use of Resperate — an over-the-counter device approved by the Food and Drug Administration to analyze breathing patterns and help guide inhalation and exhalation — lowered blood pressure. However, some researchers question whether the devices themselves or simply taking 15 minutes to relax are responsible for lowering blood pressure.
