Drinking alcohol can affect your blood pressure. Controlling alcohol consumption can help prevent high blood pressure.

Blood pressure is the force exerted by the blood against the walls of the blood vessels.

The Mayo Clinic notes that one drink a day for women, or two a day for men, can lower blood pressure by about 4 mm Hg. But when you drink above moderate consumption, alcohol can raise blood pressure by several points.

high alcohol consumption can also reduce the effectiveness of medications for blood pressure.

The American Heart Association (AHA) notes that when left untreated, high blood pressure’s damage to the circulatory system is one factor that it contributes significantly to heart attack, stroke, and other health threats.

How drinking alcohol affects your blood pressure

Drinking alcohol affects blood pressure in different ways. Medical News Today explains that alcohol increases blood levels of the hormone renin, which causes blood vessels to constrict.

Alcohol also reduces the amount of the hormone vasopressin, cortisol, increases the amount of calcium that binds to blood vessels, and also decreases the sensitivity of baroreceptors. Baroreceptors are types of receptors present in the body that help regulate blood pressure.

Myth: “Red wine is good for the heart”

The AHA claims that red wine as a heart-healthy beverage is a myth. “No research has shown a cause-and-effect link between alcohol consumption and better heart health”.

In addition to high blood pressure, excessive alcohol consumption can also lead to cardiomyopathy, cardiac arrhythmia, and even death from alcohol poisoning.

Even a single drink of wine or other alcoholic beverage can have negative effects on your body.

Red wine contains flavonoids and other antioxidants, but these Beneficial compounds can also be found in other foods such as grapes, red grape juice, or cranberries. Non-alcoholic wine can also offer you the same benefits and without the negative effects of the traditional drink.

How much alcohol is moderate alcohol consumption

One drink is equal to 12 ounces of regular beer (5% alcohol), five ounces of wine (12% alcohol), 1.5 ounces of 80-proof liquor, or one ounce of 100% spirits.

Cleveland Clinic suggests have no more than two alcoholic drinks a day (for most men) and no more than one drink a day for women and lightweight men.
