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 for men older than age 65, or more than two a day for men age 65 and younger. 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 by several points. It can also reduce the effectiveness of blood pressure medications.
