In small amounts, it has been shown to lower blood pressure by 2 to 4 mm Hg (millimeters of mercury) in women. Most experts agree, though, that does not show a significant enough drop to advise drinking for an entire population. Although daily moderate drinking has potential benefits, it can also build up your immunity to alcohol over time, leading to overconsumption. For people with atrial fibrillation, heart rate might be more important to watch, but many other heart diseases depend more on blood pressure.

  • Cutting down on your alcohol intake will decrease your risk of hypertension.
  • Ask your health care provider about a healthy waist measurement for you.
  • Some scientists suggest a J-shaped curve between alcohol and CVD, but this remains a hypothesis.
  • For multi‐arm trials, if a study reported more than one intervention arm, we identified the relevant intervention arm and included that in the review.
  • If you have high blood pressure, avoid alcohol or drink alcohol only in moderation.

First, there was the possibility of undesired bias and imprecision due to imputations of missing statistics. Most of the included studies did not report the standard error (SE)/standard deviation (SD) of the mean difference (MD) for the outcomes of interest. As described in our protocol, when we were unable to obtain the required whiskey lowers blood pressure SE/SD from study authors or by calculation from the reported P value or 95% CI, we imputed data according to the pre‐specified imputation hierarchy. We most often used the reported endpoint SE/SD value to impute the SE/SD of MD. This is known to provide a good approximation of the SD of change in BP so is unlikely to lead to bias.

It reduces bad cholesterol and fats that clog your arteries, giving way to better blood circulation. Drinking more than three shots of whiskey can raise blood pressure to a dangerous level. Whiskey is a dark, distilled spirit that started as medicine in 16th century Scotland. Doctors prescribed this liquor during the Prohibition Era for people with tuberculosis, pneumonia, and high blood pressure. But each measures distinctly different factors related to your heart health. “Alcohol consumption might affect left ventricular diastolic properties, even in nonalcoholic patients,” say the researchers.

So, we had to calculate missing MAP values from reported SBP and DBP values using the formula mentioned in the protocol and we imputed the SE/SD for those. Heart rate was increased following alcohol consumption regardless of the dose of alcohol. Alcohol has been shown to slow down parasympathetic nervous activity and to stimulate sympathetic nervous activity.

Whiskey: Is It Good For You?

In addition to certain foods that may help lower your blood pressure, some types of drinks may also be helpful. While low amounts may support brain health, in excess, studies show alcohol can disrupt how memories form. As mentioned, whiskey has antioxidant properties that decrease bad cholesterol and increase good cholesterol levels, which are good for the heart.

Bau 2005 and Bau 2011 mentioned only that investigators and volunteers were blinded to the content of the drink but did not mention the method of blinding used in these studies. Karatzi 2005 mentioned the method of blinding of participants, but it is not clear whether involved personnel were blinded as well. The method of blinding of participants and personnel was not mentioned in Dumont 2010, Mahmud 2002, and Maule 1993.

Low, moderate, and high alcohol consumption increased heart rate within the first six hours. High alcohol consumption also increased heart rate from 7 to 12 hours and after 13 hours. Most of the evidence from this review is relevant to healthy males, as these trials included small numbers of women (126 females compared to 638 males). This review did not find any eligible RCTs that reported the effects of alcohol on women separately. Because women could be affected differently by alcohol than men, future RCTs in women are needed. If future RCTs include both men and women, it is important that their blood pressure and heart rate readings are reported separately.

Among the 34 included studies, only four studies included hypertensive participants. So, it was not possible to conduct a subgroup analysis based on blood pressure. For the planned subgroup analysis based on sex, no study reported male and female participant data separately. The carry‐over effect in a cross‐over trial can confound the effects of subsequent treatment.
