5. Limit the amount of alcohol you drink

Alcohol can be both good and bad for your health. In small amounts, it can potentially lower your blood pressure by 2 to 4 mm Hg. But that protective effect is lost if you drink too much alcohol — generally more than one drink a day for women and more than two a day for men. Also, if you don’t normally drink alcohol, you shouldn’t start drinking as a way to lower your blood pressure. There’s more potential harm than benefit to drinking alcohol.

If you drink more than moderate amounts of it, alcohol can actually raise blood pressure by several points. It can also reduce the effectiveness of high blood pressure medications.

  * Track your drinking patterns. Along with your food diary, keep an alcohol diary to track your true drinking patterns. One drink equals 12 ounces (355 milliliters, or mL) of beer, 5 ounces of wine (148 mL) or 1.5 ounces of 80-proof liquor (45 mL). If you’re drinking more than the suggested amounts, cut back.
  * Consider tapering off. If you’re a heavy drinker, suddenly eliminating all alcohol can actually trigger severe high blood pressure for several days. So when you stop drinking, do it with the supervision of your doctor or taper off slowly, over one to two weeks.
  * Don’t binge. Binge drinking — having four or more drinks in a row — can cause large and sudden increases in blood pressure, in addition to other health problems.

6. Avoid tobacco products and secondhand smoke

On top of all the other dangers of smoking, the nicotine in tobacco products can raise your blood pressure by 10 mm Hg or more for up to an hour after you smoke. Smoking throughout the day means your blood pressure may remain constantly high.

You should also avoid secondhand smoke. Inhaling smoke from others also puts you at risk of health problems, including high blood pressure and heart disease.
