Does alcohol affect blood pressure?

Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS

Yes, in both directions. A drink can lower pressure for a few hours, then it rebounds higher overnight and the next day. Regular drinking above moderate levels raises average pressure steadily.

Cutting from heavy to light drinking lowers readings by roughly 3 to 5 points, sometimes more, within weeks. It is one of the most underrated blood pressure treatments.

If your readings run high, count your weekly drinks honestly and try a two week break while measuring at home. The numbers will tell you what alcohol was contributing.

If you are buying a monitor

Get an upper-arm cuff, not a wrist one, from a validated brand like Omron. Expect $30 to $60. Check the cuff size fits your arm; a too-small cuff reads high.
