If you’re not sure, make a note to tune into how much you’re having over the course of the next month or so. If it’s more than recommended, try to consciously pace your drinking to help reduce the spike in your blood pressure that excessive alcohol causes. There is certainly no reason to start drinking alcohol if you don’t already. There is also no drink, such as red wine or beer, that can be proven ‘better’ than another. Drinking alcohol to excess can cause other serious health conditions, such as cardiomyopathy (where the heart muscle is damaged and can’t work as efficiently as it used to) and arrhythmias (abnormal heart rhythms). Even a little less sodium in the diet can improve heart health and blood pressure.
Oxidative Stress
That’s partly why people who drink may find that although they’re consuming the same amount they always have, they feel the effects more quickly or strongly — that’s especially true for older women, according to the National Institute on Aging. A slower metabolism also plays a role, as do medications — prescription, over-the-counter, even herbal remedies — that are common among older people. “As you grow older, health problems or prescribed medicines may require that you drink less alcohol or avoid it completely,” the Institute says. To prevent various health complications, including high blood pressure, people should try to limit their alcohol consumption to one or two glasses infrequently. This combination of higher fluid levels in the body and smaller blood vessels increases blood pressure. When the SNS gets activated by alcohol, it can increase heart rates and constrict blood vessels.
Criteria for considering studies for this review
Many interrelated changes are possibly responsible for the biphasic effect of alcohol on blood pressure. A dose of 14 grams of pure alcohol/ethanol or less was defined as a low dose of alcohol. Refer to Characteristics of included studies and Table 4 for further details regarding these studies. All outcomes of interest in the review (BP and HR) produced continuous data. We calculated and reported mean difference (MD), with corresponding 95% confidence interval (95% CI).
- Visual inspection of funnel plots shows that the effect estimate is equally distributed around the mean in Figure 4, Figure 5, Figure 6.
- Senior Cardiac Nurse Christopher Allen finds out more from Professor Sir Ian Gilmore, Consultant Physician and Gastroenterologist at Royal Liverpool University Hospitals.
- Psychologically, however, many people feel low in mood after they’re discharged home, especially following open heart surgery.
- There is a significant amount of data to show that drinking large quantities of alcohol, whether it is a spirits, beer, or wine, can increase the risk of developing hypertension.
How alcohol affects blood pressure
In the case of detection bias, we classified nine studies as having low risk of performance bias (Agewall 2000; Bau 2005; Bau 2011; Cheyne 2004; Dai 2002; Karatzi 2013; Narkiewicz 2000; Rosito 1999; Van De Borne 1997). All studies included an independent individual who was blinded to control and test groups to evaluate and analyse the data. One study ‐ Nishiwaki 2017 (a single‐blinded study) ‐ ensured participant blinding but not blinding of outcome assessors. We classified five studies as having uncertain risk of detection bias. Karatzi 2005, Mahmud 2002, Maule 1993, and Potter 1986 did not mention the method of blinding of outcome assessors.
- It also discourages people from drinking alcohol to improve their health, although the AHA maintains that moderate drinking (no more than one drink per day for women and two drinks or fewer per day for men) is acceptable.
- For example, alcohol consumption typically has been measured through self-report.
- However, further research indicates alcohol can actually cause hypertension.
- Dr. Gonzalez explains the causes of elevated blood pressure in kids are likely a combination of modifiable factors, like diet, exercise, and obesity.
- The more often someone drinks, the more likely the habit will prod blood pressure readings beyond normal levels.
Different levels of daily wine consumption (i.e., sometimes, 1 to 2 glasses/day, and ≥3 glasses/day) had no effect on fatal or nonfatal outcomes (e.g., hospitalization for a CV event). Subjects who drank wine more often, however, were less likely to have symptoms of depression and more likely to have a better perception of health status. They also had lower levels of circulating inflammatory markers, such as C-terminal what does alcohol do to your blood pressure proendothelin-1 and pentraxin-3 (Cosmi et al. 2015). Older studies had shown potential benefits of moderate drinking of red wine, but more recently it has been proven that no level of alcohol consumption is considered safe, or can reduce the risk of hypertension. Drinking too much alcohol can raise blood pressure to unhealthy levels. Having more than three drinks in one sitting temporarily raises blood pressure.
- Mechanisms related to the positive and adverse effects of alcohol on cardiovascular conditions, such as coronary heart disease and stroke as well as cardiomyopathy.
- Research from 2019 found that drinking 32 ounces (oz) of energy drink in an hour could increase blood pressure.
- Diastolic blood pressure is the pressure in the arteries between heartbeats.
- One area of interest is how the consumption of alcohol impacts blood pressure.
- 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.

On the other hand, Fantin 2016 allowed participants to continue drinking during the period of outcome measurement. These differences in alcohol consumption duration and in outcome measurement times probably contributed to the wide variation in blood pressure in these studies and affected overall results of the meta‐analysis. We did not consider the lack of blinding of participants as a downgrading factor for certainty of evidence because we do not think that it affected the outcomes of this systematic review. Changes in blood pressure and heart rate after alcohol consumption were not the primary outcomes of interest in most of the included studies.
Review authors included nine studies involving a total of 119 participants, and the duration of these studies was between four and seven days. Participants in those studies consumed alcohol regularly during the study period, whereas in our systematic review, we included only studies in which participants consumed alcohol for a short period. Based on nine studies, McFadden 2005 reported that the mean increase in SBP was 2.7 mmHg and in DBP was https://ecosoberhouse.com/ 1.4 mmHg. Only three of these studies measured BP at various time points and found that alcohol has a hypotensive effect lasting up to five hours after alcohol consumption and a hypertensive effect 20 hours after alcohol consumption that lasts until the next day. The inclusion of non‐randomised studies in McFadden 2005, which are known to be at higher risk of bias, is likely the reason for the discrepancy in the magnitude of BP effects.
Alcohol increases blood levels of the hormone renin, which causes the blood vessels to constrict. This measurement takes into account the systolic blood pressure and the diastolic blood pressure. In addition to cutting back on alcohol, you can incorporate other lifestyle changes, such as regular exercise and stress management, to help lower your blood pressure.

We contacted study authors for missing or unclear information required for the risk of bias assessment and then reassessed the domains once the information was available. One area of interest is how the consumption of alcohol impacts blood pressure. However, even drinking small amounts of alcohol may contribute to high blood pressure. This may be due to alcohol affecting the chemicals in the body that control blood vessel constriction and fluid levels. In a 2019 study of 17,059 males and females, researchers observed that people who drank a moderate amount of alcohol compared to none were 53% more likely to have stage 1 hypertension and two times more likely to have stage 2 hypertension.
