So, we decided to conduct a sensitivity analysis of the included studies based on the blinding condition (Table 7). We observed a greater reduction in blood pressure after a moderate dose of alcohol consumption for the unblinded studies, which was probably due to the presence of a heterogeneous population. For high‐dose alcohol studies, we did not find any significant difference between blinded and unblinded studies. Regular or heavy drinking can raise cortisol levels, which may contribute to elevated blood pressure and other cardiovascular risks.
Alcohol and Hypertension
- Surprisingly, most of the salt people consume doesn’t come from the saltshaker — it comes from packaged and restaurant foods.
- The aim of Bau 2011 was to determine the effects of alcohol on heart rate variability, so study authors did not measure and report DBP.
- Individual genetic differences can explain varying blood pressure responses to similar alcohol consumption levels.
- As a service to our readers, Harvard Health Publishing provides access to our library of archived content.
In the case of performance bias, we classified six studies as having low risk of bias, 19 studies as having high risk of bias, and seven studies as having unclear risk of bias. We contacted the study authors for missing or unclear information relevant to the review using contact information provided in their respective articles. If the dose of a study was not reported in the article and the study author did not respond to our request, we excluded that study. Your blood pressure is elevated if it is 120 to 129 systolic and 80 to 89 diastolic. There are few strategies for the control, prevention https://africacataracts.org/is-wine-actually-good-for-you-benefits-and-risks/ and treatment of alcohol-induced hypertension as shown in Figure 2. The American College of Cardiology and the American Heart Association divide blood pressure into four general categories.
- If we were not able to get SD from the study authors or calculate SD from the values mentioned above, we imputed SD using the following hierarchy (listed from highest to lowest) (Musini 2014).
- While alcohol consumption is known to impact blood pressure levels, it is also important to consider other lifestyle factors that can influence hypertension.
- According to our pre‐specified dose categories, both 15 g and 30 g of alcohol fell under the medium dose category.
- Physical conditioning attenuates the chronic ethanol-induced hypertension by augmenting the NO bioavailability and reducing the oxidative stress response in rats19,79,108.
- Some people believe drinking alcohol in moderation, particularly red wine, is beneficial for your blood pressure.

Additionally, it stabilizes hormones such as renin and aldosterone thus promoting heart health. Withdrawal of alcohol reduces blood pressure which leads to weight loss, this also controls hypertension. Alcohol is a calorie-dense beverage so its reduction or toral withdrawal can lead to weight loss and reduce pressure on the heart and blood vessels. Additionally, alcohol reduction or withdrawal reduces the chances of heart disease and it also enhances sleep quality.

In this comprehensive guide, we will explore how alcohol affects blood pressure, the short- and long-term mechanisms involved, why moderation is key, recommendations from health authorities, and practical tips to minimize risks. Whether you’re curious about cutting back, worried about newly diagnosed hypertension, or looking for ways to support a loved one, this resource can help you make informed decisions about alcohol and cardiovascular well-being. It can interfere with the effectiveness of blood pressure medications, reducing their ability to control hypertension effectively. Therefore, limiting alcohol intake—avoiding binge episodes and adhering how does alcohol impact blood pressure to recommended guidelines—is vital for maintaining stable blood pressure and reducing cardiovascular risks. Remember, it’s essential to drink responsibly and be mindful of your alcohol intake. If you’re concerned about your drinking habits or blood pressure, consult with a healthcare professional for personalized advice.
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. We did not identify enough studies to construct a funnel plot for the outcomes under low doses of alcohol. We interpreted only funnel plots that were constructed based on studies reporting outcomes under medium dose and high dose of alcohol versus placebo comparisons. Dumont 2010, Karatzi Sobriety 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.
Moreover, alcohol affects physiological mechanisms regulating blood pressure. It can activate the sympathetic nervous system and raise levels of stress hormones such as cortisol and renin, further constricting blood vessels. Alcohol consumption influences blood pressure in a way that depends on the amount and frequency of drinking. Moderate drinking, defined as up to one drink per day for women and two for men, often causes little to no change, and in some cases, a slight temporary decrease in blood pressure immediately after drinking. However, consuming alcohol beyond these guidelines, especially in larger quantities or during binge episodes, can significantly raise blood pressure.
