This review aimed to quantify the acute effects of different doses of alcohol over time on blood pressure and heart rate in an adult population. However, there were far fewer studies that focus on African Americans for the researchers to review, and more research may be needed. ”We found participants with higher starting blood pressure readings, had a stronger link between alcohol intake and blood pressure changes over time. Whelton is also the chair of the American Heart Association’s 2017 Hypertension Practice Guidelines and a member of the writing committee for the Association’s 2021 Scientific Statement on Management of Stage 1 Hypertension in Adults. Heart rate was increased by 4.6 bpm six hours after drinking alcohol compared to placebo.

For light drinkers or those who consume alcohol occasionally, the effects on blood pressure may be minimal or even negligible. Some studies suggest that small amounts of alcohol might temporarily lower blood pressure due to its vasodilating effects (relaxing blood vessels). However, this is a short-lived benefit and should not be mistaken for a health benefit. When you drink alcohol, it’s quickly absorbed into your bloodstream through the stomach and small intestine. From there, it travels to your liver for processing, but some circulates throughout your body, affecting your heart, arteries, and blood pressure. This rapid absorption is why alcohol can have almost immediate effects, from relaxation to raising your blood pressure, depending on how much and how often you drink.
- This review summarises the acute effects of different doses of alcohol on blood pressure and heart rate in adults (≥ 18 years of age) during three different time intervals after ingestion of alcohol.
- Karatzi 2013Maufrais 2017 and Van De Borne 1997 measured blood pressure before and after treatment but did not report these measurements.
- In the United States, 14 grams of pure alcohol is considered as one standard drink or one unit, and the maximum daily limit for men and women is four and three drinks, respectively (NIAAA 2017).
- A 2023 report found that drinking too much alcohol regularly, exceeding 30 grams per day, can significantly increase the risk of developing high blood pressure.

It is important to note that the dose of alcohol was comparatively higher (≥ 60 g or ≥ 1 g/kg) in nine studies (Bau 2005; Buckman 2015; Hering 2011; Narkiewicz 2000; Rosito 1999; Rossinen 1997; Stott 1987; Van De Borne 1997; Zeichner 1985). Two review authors (ST and CT) performed data extraction independently using a standard data collection form, followed by a cross‐check. In cases of disagreement, the third review authors (JMW) became involved to resolve the disagreement. When necessary, we contacted the authors of studies for information about unclear study design. All extracted data were entered and double‐checked in RevMan 5.3 software (Review Manager (RevMan)). Randomised controlled trials (RCTs) comparing effects of a single dose of alcohol versus placebo on blood pressure (BP) or heart rate (HR) in adults (≥ 18 years of age).
How Does Alcohol Affect Blood Pressure?
Consuming alcohol can increase the risk of high blood pressure and other metabolic conditions in several ways. For example, alcohol can affect calcium levels, cortisol levels, and baroreceptor sensitivity, all of which can lead to increases in blood pressure. Older adults — drinkers, nondrinkers, it doesn’t matter — are already at risk for hypertension. Research suggests that 74.5 percent of people 60 and older have high blood pressure, compared with 54.5 percent of adults ages 40 to 59. Several factors are to blame, one being your body’s network of blood vessels, which changes with https://ecosoberhouse.com/ age.
- Both ST and CT independently assessed studies for inclusion or exclusion and assessed the risk of bias of all included studies.
- An increase in plasma renin results in increased production of angiotensin I (AI), which is converted to angiotensin II (AII) by angiotensin‐converting enzyme (ACE).
- Sometimes, it’s hard to avoid alcoholic beverages at social events, but excessive alcohol consumption may increase your risk of high blood pressure.
- But beneath the surface of this seemingly harmless indulgence lies a complex interplay between alcohol and our cardiovascular system.
- Of the 32 included studies, seven studies used a manual mercury sphygmomanometer or a semi‐automated sphygmomanometer for BP measurement (Bau 2005; Dai 2002; Karatzi 2005; Kojima 1993; Potter 1986; Rossinen 1997; Van De Borne 1997).
Moderate‐certainty evidence indicates an increase in heart rate after 7 to 12 hours and ≥ 13 hours after high‐dose alcohol consumption, low certainty of evidence was found for moderate dose of alcohol consumption. Hence, we conducted additional analyses to see if the very high dose of alcohol (≥ alcohol rehab 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 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.

Previous research suggests that acute alcohol consumption affects the renin–angiotensin–aldosterone system (RAAS) by increasing plasma renin activity (Puddey 1985). The RAAS is responsible for maintaining the balance of fluid and electrolytes. An increase in plasma renin results in increased production of angiotensin I (AI), which is converted to angiotensin II (AII) by angiotensin‐converting enzyme (ACE). The hormone AII is a potent vasoconstrictor that stimulates aldosterone and vasopressin secretion from the adrenal gland, promoting sodium and water retention (Schrier 1999). As a result, peripheral resistance and blood volume are increased, leading to elevated arterial blood.
