The acute effects of alcohol on the myocardium include a weakening of the heart’s ability to contract (negative inotropic effect). Alcoholic drinks, such as beer, spirits and wine, contain the depressant drug ethyl alcohol (ethanol). Depressants inhibit many of the brain’s functions, such as slowing down its control of the body, with even just small amounts affecting important functions like speech and movement. If you experience persistent or severe symptoms like a fast heartbeat after drinking or irregular heartbeats, chest pain, dizziness, or shortness of breath after drinking alcohol, seek medical attention promptly. A 2009 study, on the other hand, which was carried out on a pack of rats, showed that in stressful situations, a dose of CBD for blood pressure has the potential to reduce the heart rate in mammals.
How Benzodiazepines Are Used to Manage Alcohol Withdrawal
Moreover, alcohol stimulates the sympathetic nervous system, triggering the release of adrenaline, which further makes the heart rate high after drinking. Additionally, alcohol disrupts the balance of electrolytes like potassium and magnesium, which play crucial roles in regulating heart rhythm. Based on the same study referenced above, there is evidence that CBD may have an effect on heat rate. In particular, the study demonstrated that individuals who were administered CBD experienced a +10bpm increase in their heart rate. The question of whether alcohol raises blood pressure the next day is a topic of interest and concern for many individuals, particularly those who consume alcohol regularly.

Caffeine temporarily raises blood pressure in some individuals, especially those not accustomed to it. The key is to monitor how caffeine affects your body—checking blood pressure before and after coffee can reveal personal sensitivity. For some, switching to green tea provides a gentler stimulant with added antioxidants.
According to the meta-analysis, people who had around 3.5 drinks per day saw their systolic blood pressure increase by nearly five points and their diastolic blood pressure increase by three points over five years. Another study, this time in the Journal of the American Heart Association, indicates that binge drinking drug addiction increases blood pressure levels in men but not women. This is because alcohol stimulates the nervous system, which increases the heart rate and narrows blood vessels, leading to a short term rise 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 age.

- Upon quitting alcohol, some people may experience temporary spikes in blood pressure during withdrawal.
- While occasional moderate drinking may not pose a major problem for some, many people are highly vulnerable to alcohol-induced hypertension.
- We most often used the reported endpoint SE/SD value to impute the SE/SD of MD.
- That fourth drink at the bar may feel like it’s relaxing you, but it’s actually affecting your body differently than you might think.
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. It is a common substance of abuse and its use can lead to more than 200 disorders including hypertension. 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.
Consulting with healthcare professionals for personalized advice and guidance is always recommended. 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. Although eligible studies included East Asian, Latino, and Caucasian populations, they lacked African, South Asian, and Native Hawaiian/other Pacific Islander representation.

While red wine contains antioxidants like resveratrol that may have heart-health benefits, drinking too much wine still increases the risk of high blood pressure and cardiovascular problems. Recent large-scale studies show that people who drink red wine regularly still have higher blood pressure than those who do not drink at all. The cardiovascular risks of alcohol consumption outweigh any theoretical benefits from wine antioxidants. Lauren Manaker, MS, RDN, LD, CLEC, CPT, a registered dietitian based in Charleston, also points out that although red wine has some compounds linked to positive health benefits, it’s still alcohol at the end of the day. “Alcohol is classified as a Group 1 carcinogen by the International Agency for Research on Cancer, which is the same classification as tobacco,” Manaker says.

And sure, we’ve all had a night does alcohol increase or decrease blood pressure here or there where we’ve had one too many and we know it. But it’s important to make sure those nights of overindulgence are the exception and not the rule. 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. Moreover, alcohol may interact with certain blood pressure medications, affecting the level of the medication in the body or increasing side effects. This can potentially worsen the condition of the heart and lead to further complications.
However, other evidence from the same study appears to contradict this claim, and more research is needed to confirm or deny this hypothesis. Evidence shows that long-term alcohol abuse contributes to your risk of alcoholic cardiomyopathy, a type of heart disorder where your heart becomes less effective at pumping blood through your body. Although this may not make your actual heart rate slower, it can increase your risk of heart failure. For example, alcohol consumption typically has been measured through self-report.
Some of the potential cellular changes related to ethanol consumption reviewed above are illustrated in figure 5. More than one cellular event may be happening at the same time, and, as with other chronic health conditions, the relevant mechanisms may be synergistic and interrelated. Researchers have found evidence of mitochondrial dysfunction or impaired bioenergetics related to alcohol consumption. This is not surprising, because mitochondria are a major target for free-radical injury. Dysfunctional mitochondria are less efficient, can become a source of ROS, and are more likely to initiate apoptosis (Marzetti et al. 2013).
