Some data relied on self-reporting; further data could include more diverse samples. Hence, we conducted additional analyses to see if the very high dose of alcohol (≥ 60 g or ≥ 1 g/kg) had any dose‐related effects compared to lower high doses of alcohol (31 to 59 g of alcohol) (see Substance abuse Table 9). Results suggest that the decrease in BP with very high doses of alcohol is greater compared to lower high doses of alcohol. However, the result was heterogeneous; therefore, we are unable to make any implications from this.

But doctors now believe that alcohol doesn’t serve up any heart benefits. Women should be especially cautious about alcohol, Goldberg says, as they may be more likely than men to develop health problems, particularly among young or middle-aged women who have eight or more drinks a week. An occasional drink may not make a significant difference if your high blood pressure is under good control with medication and/or healthy habits like diet and exercise. Studies published in the American Heart Association’s scientific journals are peer-reviewed. The statements and conclusions in each manuscript are solely those of the study authors and do not necessarily reflect the Association’s policy or position.

Increase and decrease in blood pressure
These studies compare people with a gene variant that makes it unpleasant to drink to people without the gene variant. One of these studies found people with the gene variant have a lower risk of heart disease — another blow to the idea that alcohol protects people from heart problems. That idea that moderate drinking has health benefits came from imperfect studies comparing groups of people by how much they drink. And none of the studies randomly assigned people to drink or not drink, so they couldn’t prove cause and effect.
- If this is not available, use body heat from other parts of the body to warm the area, such as by placing frostbitten hands or fingers in an armpit.
- For Buckman 2015, blood pressure was recorded beat to beat continuously, but DBP was not reported.
- On Friday, U.S. Surgeon General Dr. Vivek Murthy called for updating the existing surgeon general’s health warning label on alcohol-containing beverages to include the risk of cancer.
- Moderate‐certainty evidence shows that acute consumption of medium to high doses of alcohol decreases blood pressure within the first six hours and for up to 12 hours after alcohol consumption.
- Dumont 2010 measured blood pressure during the study period, but study authors did not provide the before and after measurement of SBP.

Excessive alcohol consumption can increase the risk of several metabolic conditions, including high blood pressure. Studies have shown that a good percentage of people who drink alcohol also smoke, which can raise blood pressure as well. “Those who drink heavily are three times as likely to be hypertensive” as those who abstain. Some health problems in people older than age 65, and the medicines used to treat them, can get worse with alcohol’s effects.

Although some of those effects can occur without alcohol consumption, avoiding alcohol helps decrease the risks. Recent data suggest that moderate and heavy drinking contributes to high blood pressure in men and women. Khraishah published a paper in the journal Stroke last year that found extreme temperatures—both hot and cold—increased the risk of dying from a stroke. Other studies have shown a greater risk of death from multiple cardiovascular conditions—especially heart failure—during periods of extreme cold.
Data and analyses
We classified six studies as having low risk of https://ecosoberhouse.com/ performance bias (Dai 2002; Narkiewicz 2000; Nishiwaki 2017; Potter 1986; Rosito 1999; Van De Borne 1997). In this study, all test drinks were poured into paper cups to achieve blinding of participants. We contacted the author of Rosito 1999 to request additional information regarding the method of blinding used.
Drinking raises the risk of several types of cancer, including colon, liver, breast and mouth and throat. Alcohol breaks down in the body into a substance called acetaldehyde, which can damage your cells and stop them from repairing themselves. Moderate drinking was once thought to have benefits for the heart, but better research methods have thrown cold water on that.
- An occasional drink may not make a significant difference if your high blood pressure is under good control with medication and/or healthy habits like diet and exercise.
- You may have seen headlines that linked having one drink a day to a greater rise in blood pressure with age, compared to people who don’t drink at all.
- For selective reporting for heart rate (HR), we classified only Koenig 1997 as having high risk of bias because heart rate was not reported.
- While this might seem minor, repeated short-term spikes can accumulate, potentially leading to sustained hypertension over time.
- Another reason behind the heterogeneity was probably the variation in alcohol intake duration and in the timing of measurement of outcomes across the included studies.
- Methodological differences between studies might have affected measurement of the reported outcomes.
The dose of alcohol had to be reported by study authors for inclusion in the systematic review. Because there are no published standards for differentiating between low and medium doses of alcohol, we chose the alcohol content in one standard drink as the threshold between low dose and medium dose. Because the alcohol content in one standard drink varies among different countries (ranging from 8 g to 14 g), we chose the Canadian standard for an alcoholic beverage, which is 14 g of pure alcohol (CCSA). Accordingly, we considered up to 14 g of alcohol as a low dose of alcohol. To differentiate between medium and high doses, the Canadian Centre on Substance Use and Addiction (CCSA) identifies less than 30 g of alcohol for men and less than 20 g of alcohol for women as the threshold for low risk of alcohol intake (CCSA).
This puts them at higher risk for falls, broken bones, and car crashes tied to drinking. If you’re generally healthy, you certainly don’t have to ― although you’d be hard-pressed to find a how does alcohol effect blood pressure health expert who will suggest you drink alcohol to improve your health. What we do know for sure is that you want to avoid heavy alcohol consumption. Factors such as age, mental health, existing medical conditions and drug use can affect the impact of alcohol on an individual. Regular excessive drinking has a clear link to ongoing high blood pressure. She notes that it can cause an enlarged heart (alcoholic cardiomyopathy), which weakens your heart and makes it harder to pump blood.
We created three SoF tables to show the certainty of evidence and the summary of effects on outcomes of interest (SBP, DBP, and HR) for high (Table 1), medium (Table 2), and low doses (Table 3) of alcohol. We identified Stott 1987 and Barden 2013 from Analysis 3.1 and Analysis 3.2 as having a considerably lower standard error (SE) of the mean difference (MD) compared to the other included studies. Assuming that the low SEs of MDs reported in Stott 1987 and Barden 2013 are errors and are not reliable, we replaced these measures with the average SE of MD from the rest of the included studies. Dumont 2010, Karatzi 2013, Kawano 1992, and Williams 2004 reported reasons for participant withdrawal and excluded their data from the final analysis. Data were balanced across groups, hence missing data did not affect the final results. Alcohol has been reported to diminish baroreceptor sensitivity, which is a key factor in regulating blood pressure (Abdel‐Rahman 1985; Rupp 1996).
