Drinking too much alcohol is not good for health. It is highly recommended that people consume less alcohol. Drinking too much alcohol cannot only increase your blood pressure but can ruin your liver and brain. If you already have high blood pressure, then you should cut back on your drinking. In general, one drink a day or about 12 ounces is fine. If you are on the heavy side, start walking since alcohol also contains many calories, which also worsens blood pressure.
