How Drinking Alcohol Influences Your Heart Rate at Rest

Alcohol is a common part of social gatherings and relaxation routines, but how does it impact your heart specifically your resting heart rate? Whether you're enjoying a glass of wine with dinner or an occasional cocktail, it’s important to understand the effects alcohol can have on your cardiovascular system.

Alcohol’s Short-Term Impact on Your Heart

If you’ve ever noticed your heartbeat quicken after a drink, you’re not imagining it. Alcohol can have immediate effects on your heart rate and blood pressure.

According to a January 2017 review in ‌Alcohol Research‌, consuming alcohol in excess can lead to a temporary irregular or elevated heart rate. Here’s why:

• Dehydration: Alcohol is a diuretic, which means it causes your body to lose fluids. This can lead to low blood pressure, prompting your heart to beat faster to compensate, explains Marc Eisenberg, MD, a cardiologist at Columbia University Irving Medical Center.

• Blood Pressure Drops: In some cases, alcohol lowers your blood pressure, which further stresses your heart as it works to stabilize your circulation.

How to Mitigate Short-Term Effects

You don’t have to give up alcohol entirely to reduce these short-term heart effects. Instead:

• Moderate Your Intake: Stick to the Dietary Guidelines for Americans' definition of moderate drinking up to one drink per day for women and two for men.

• Stay Hydrated: Drink water between alcoholic beverages to maintain proper hydration.

• Eat While Drinking: Consuming food with alcohol slows its absorption and helps stabilize your body’s response.

Long-Term Effects of Heavy Drinking on the Heart

While moderate alcohol consumption has been associated with certain heart health benefits in some studies, heavy or consistent binge drinking can lead to significant cardiovascular issues over time, according to the American Heart Association (AHA).

Risks of Chronic Heavy Drinking

• Increased Heart Strain: Regular overconsumption of alcohol can cause persistent elevated heart rates, placing undue stress on your heart.

• Organ Damage: Excessive drinking strains not just your heart but also other organs, which can exacerbate cardiovascular problems.

• Irregular Heart Rhythms: Binge drinking episodes may trigger atrial fibrillation (AFib), a condition linked to a higher risk of stroke and heart failure.

Who Should Avoid Alcohol?

Not everyone can safely consume alcohol, even in moderation. The AHA recommends that the following groups avoid alcohol altogether:

• People Under 21: Younger individuals are more vulnerable to the harmful effects of alcohol on developing organs.

• Pregnant Individuals: Alcohol can harm fetal development.

• Those With Certain Health Conditions: Conditions like gout, hepatitis, and depression may worsen with alcohol use.

If you don’t already drink alcohol, experts caution against starting solely for potential health benefits, as these have not been definitively proven.

The Bottom Line

Alcohol’s effect on your resting heart rate and overall cardiovascular health depends largely on the amount and frequency of your drinking. While moderate consumption may not harm most people, excessive or frequent drinking can have both immediate and long-term consequences for your heart.

To protect your heart health, stick to moderation, stay hydrated, and consult your doctor if you have concerns about alcohol and your health.
