How alcohol can damage the cardiovascular system – The heart and blood vessels form part of the cardiovascular system.1 Blood is pumped around the body by the heart, via these blood vessels through arteries, capillaries and veins.2 The blood delivers nutrients and other materials to all parts of the body, including alcohol, which is absorbed directly into the blood stream mainly via the stomach and small intestine. The cardiovascular system is affected by alcohol. At the time of drinking, alcohol can cause a temporary increase in heart rate and blood pressure. In the long-term, drinking above the guidelines can lead to on-going increased heart rate, high blood pressure, weakened heart muscle and irregular heartbeat. All of which can increase the risk of alcohol-caused heart attack and stroke. Increased heart rate Heart rate is the number of times the heartbeats per minute. Alcohol can cause variability in the way the heart beats – the time between heart beats. Studies have found that regular heavy drinking can cause episodes of tachycardia (increased heart rate due to problems in the electrical signals that produce a heartbeat).6, 7 Complications due to regular episodes of tachycardia, do vary depending on their frequency, length and severity, but it can cause blood clots that can lead to a heart attack or stroke.8 Increased blood pressure Blood pressure is a measure of the force blood places against blood vessel walls. High blood pressure is when the blood is pumping with more force than normal through the arteries.10 Drinking alcohol on a single occasion can see a temporary increase in blood pressure, and regularly drinking alcohol above the national guidelines can cause alcohol-caused hypertension (high blood pressure). It is likely there are multiple mechanisms which cause alcohol to raise blood pressure, 11 and studies have shown that a reduction in alcohol intake can lower blood pressure.12 High blood pressure can cause hardening and thickening of the arteries, and is a risk factor for heart attack and stroke.13, 14 The Australian Heart Foundation recommends having no more than two standard drinks on any day, as studies have found the consumption of more than two standard drinks a day can see an immediate increase in blood pressure, and increases the risk of developing hypertension.15 Weakened heart muscle The heart is critical in getting oxygen and nutrients around the body and achieves this by generating the pressure for blood to circulate around the body, ensuring blood only flows in one direction. The frequency and force of the hearts contractions adjust depending on the needs of the body.17 The anatomy of the heart is complex, but the heart’s ability to contract is due to the muscle layer within the heart wall.18 Heart muscle is called myocardium, and damaged heart muscle is called cardiomyopathy. Heavy alcohol consumption can lead to cardiomyopathy.19 Dilated cardiomyopathy results in weakened heart muscle that causes the four heart chambers to enlarge, resulting in weaker contractions (this makes it harder for the blood to circulate around the body).19, 20 Cardiomyopathy can eventually lead to congestive heart failure, which is when the heart doesn’t pump enough for the needs of the body.21, 22 Irregular heart beat A change in heart rhythm is called an arrhythmia. Arrhythmias can occur because of changes to the heart’s electrical system, which can be caused by blocked signals, abnormal pathways, irritable heart cells, medicines and stimulants. Some of the common arrhythmias include the heart beating too slow (bradycardia), or too fast (tachycardia).23 Arrhythmias can cause cardiac arrest and stroke. The occurrence of acute cardiac rhythm disturbances (atrial fibrillation is the most common) have been found to be induced by alcohol. Sometimes referred to as ‘holiday heart’ these disturbances were found to be more frequent after weekends or holidays like Christmas or New Years which are known to have higher alcohol consumption.28> Atrial fibrillation Atrial fibrillation is one type of arrhythmia, and causes the upper chambers of the heart (the atriums) to quiver rather than beat normally.24 Alcohol causes atrial fibrillation through multiple mechanisms and can be seen both acutely (after one off drinking occasion) and from the cumulative effects of alcohol on the heart muscle.26, 27 This means blood does not circulate as efficiently as it should. This can result in blood, which hasn’t left the atrium, pool and clot. If the blood that has clotted within the atrium breaks off and is within the blood stream it can lodge in an artery within the brain causing an ischemic stroke.25
Does alcohol decrease heart rate?
1. What is alcohol? – Alcohol is a ‘depressant’ drug, meaning your brain’s control of your body is being slowed down. Even a small amount can affect important functions like speech and movement. Drinking very large amounts all at once can slow your heart rate and breathing down to a dangerously low level.
How much does alcohol increase heart rate?
Credit. Aileen Son for The New York Times Ask Well Drinking can elevate your pulse, which isn’t a concern for most healthy adults, though those with heart rhythm problems should use caution. Credit. Aileen Son for The New York Times My smartwatch shows me that my sleeping heart rate is much higher at night after I’ve had a couple of glasses of wine.
- It’s normally around 60 beats per minute, but it spikes up to 80 to 100 if I drink more than a glass of wine.
- Is that normal? We all know that a glass or two of wine can help you relax and unwind.
- But alcohol can also have pronounced effects on your cardiovascular system in the hours after you consume it, causing your heart to beat faster, at least in the short term.
And in general, the more you drink, the greater the uptick in your heart rate. Experts say that for most healthy adults, a temporary increase in heart rate caused by one or two drinks is probably not something to worry about. But it could be problematic for people who have conditions that cause irregular heart rhythms, such as atrial fibrillation or other types of arrhythmias, or for those who are at high risk for heart attacks or strokes.
- Last year, a group of researchers analyzed data from 32 different clinical trials of alcohol consumption involving 767 people; most were healthy young men in their 20s and 30s.
- They saw distinct patterns in how alcohol affected their heart rates and blood pressure readings shortly after drinking.
- In general, a normal resting heart rate for adults is between 60 and 100 beats per minute.
The researchers found that consuming one standard drink — generally defined as a 12-ounce beer, a five-ounce glass of wine or a cocktail containing 1.5 ounces of liquor — tended to elevate the participants’ heart rates by about five beats per minute in the six hours that followed.
With two or more drinks, the increase in heart rate was greater, and heart rates remained slightly elevated up to 24 hours later. Alcohol also had distinct effects on blood pressure. A single drink had little effect on blood pressure, but when people consumed two drinks, they experienced a slight dip in their blood pressure levels in the hours that followed.
When they had more than two drinks, however, they saw their blood pressure levels fall at first and then begin to climb, eventually becoming slightly elevated about 13 hours after they drank. The findings on blood pressure seem to square with other studies that have shown that light drinking can be slightly beneficial to cardiovascular health, causing your blood vessels to dilate and blood pressure to fall, but that having more than two drinks on one occasion can stress your circulation.
- It’s common for people to drink in the evening.
- So scientists have also looked at what happens when people consume alcohol before going to bed.
- In one study published in January, researchers recruited 26 men and women and had them spend three nights in a lab where they were monitored as they slept.
- On one occasion, the participants consumed what are considered “moderate” amounts of alcohol before going to bed: The women each had one glass of wine, and the men drank two glasses of wine.
On another night, the participants drank heavier amounts: The women drank three glasses of wine, and the men had four. On the third night, they were all given nonalcoholic wine, which served as a placebo. Image 
Credit. Aileen Son for The New York Times The researchers found that when people drank moderate amounts of wine, their nighttime heart rates rose by 4 percent compared with when they did not drink alcohol. But their heart rates returned to normal in the morning hours.
When people drank heavier amounts, however, their nighttime heart rates spiked 14 percent and remained elevated into the morning. The study also found that alcohol, especially when consumed in higher amounts, temporarily lowered the participants’ heart rate variability, a measure of the variation in time between heartbeats.
A higher variability is generally a sign of better cardiovascular fitness. One particularly striking study published in 2017 looked at how alcohol can affect your heart rate in social settings. The study was carried out at the Munich Oktoberfest, the world’s largest public beer festival.
The researchers recruited more than 3,000 men and women who had been drinking, but were not legally impaired. They tested their blood alcohol concentrations and gave them EKGs to assess their cardiac function. They found that about 26 percent of the revelers had a resting heart rate above 100 beats per minute, a risky but not life-threatening condition known as sinus tachycardia.
About 5 to 6 percent of the participants showed other types of irregular heartbeats that are considered more dangerous, including atrial fibrillation, which can lead to serious complications such as strokes. The higher the participants’ breath alcohol concentrations, the greater their odds of having one of these irregular heart rhythms.
Dr. Stefan Brunner, a cardiologist at the University Hospital of Munich and an author of the study, said his findings demonstrate that in general, heart rate climbs continuously with increasing blood alcohol levels, but not everyone shows the same level of susceptibility. “Some people react more profoundly with an increasing heart rate than others,” he said, though it’s unclear why that is.
Some people may simply have a higher tolerance for alcohol, he said. Dr. Brunner emphasized that for most healthy adults, an increase in heart rate in response to alcohol should not be alarming, especially if you are drinking in moderation, which the Dietary Guidelines for Americans defines as no more than one drink a day for women and up to two drinks per day for men.
- An increase in heart rate from 60 to 80 to 100 beats per minute is not of concern and just reflects the influence of alcohol,” Dr.
- Brunner said, though he added that you should be concerned if you experience palpitations after drinking or if your smartwatch alerts you to an abnormal heart rhythm such as atrial fibrillation.
You should also be cautious if you have strong risk factors for developing a heart rhythm disorder, such as high blood pressure or coronary artery disease, or if you have experienced arrhythmias in the past. One recent trial published in the Annals of Internal Medicine found that just one can of beer or a single glass of wine could cause an episode of atrial fibrillation in people who have a history of the condition.
Dr. Peter Kistler, a cardiologist and expert on heart rhythm disorders, said that people with arrhythmias can drink alcohol, but that they should do so only occasionally, limiting themselves to just one standard drink no more than three or four times a week. Avoiding alcohol altogether, however, could make a big difference.
Dr. Kistler’s research has shown that in people with recurrent arrhythmias who were regular drinkers, giving up alcohol cut their rate of events in half.
Why does alcohol increase your heart rate?
Blood Vessel Dilation – Drinking alcohol also causes your blood vessels to expand and dilate. In response, the heart starts to pump more blood to keep the body in homeostasis. The heart has to beat faster and faster to keep enough blood circulating. This is another way heart rate increases after consuming alcohol, and is also the reason why you might feel warm or flushed after drinking.
Does caffeine raise heart rate?
What Happens to the Heart When You Consume Caffeine? – Once you take that first sip of coffee, the caffeine enters your blood from the stomach and small intestine and begins to stimulate your central nervous system. The receptors in the cells within your heart are stimulated by the caffeine and increases your heart rate.
Is a heart rate of 120 normal?
Is 120 Pulse Rate Normal? Normal Rates by Age & Warning Signs 
A resting pulse rate of 120 BPM in adults would be considered high, while a heart rate between 60 beats per minute (BPM) and 100 BPM is normal for people 15 years and older. The pulse rate, also called your heart rate, is the number of times the heartbeats per minute (BPM). Your pulse can be felt on your:
Wrists Inside of the elbow Side of the neck Top of the foot
Place your finger (not your thumb) over your pulse and count the number of beats in 60 seconds to get your heart rate. According to the American Heart Association, a normal adult resting heart rate is between 60 beats per minute (BPM) and 100 BPM for people 15 years and older.
| Age range | Pulse Rate/Heart Rate (beats per minute, or BPM) |
|---|---|
| Newborn | 100-160 |
| 0-5 months | 90-150 |
| 6-12 months | 80-140 |
| 1-3 years | 80-130 |
| 3-5 years | 80-120 |

Why is my heart rate so high when hungover?
What can make a hangover better? – In general you’ll just have to wait it out – there are no simple hangover cures. But there are some things that can help you feel better after overindulging. Keep your fluids up – regularly sipping water will ease symptoms of dehydration and should improve a headache.
- And having a snack can help settle your stomach and increase your blood sugar levels.
- Also, it’s important to realise that if you are hungover, there is a chance that your blood alcohol concentration is still too high to be able to drive safely.
- It may also not be safe for you to work if you are over the limit.
Even if your blood alcohol level has returned to normal, when your concentration is affected you should avoid driving, work and other tasks that could be dangerous if you are impaired.
Why you shouldn’t drink alcohol before bed?
How does alcohol affect sleep? Plenty of people have a drink to help them sleep at night. While alcohol is a sedative and can have relaxing or calming effects, a nightcap isn’t the best way to get a good night’s sleep. As a sedative, alcohol interferes with all kinds of brain signals, causing well-known signs of drunkenness — slower reflexes and problems with coordination, balance, speech, and judgement.
Drinking also affects how the brain controls sleep-wake cycles, and the effects can last hours after the alcohol has cleared out. For the first half of the night, drinking close to bedtime means more deep, dreamless slow-wave sleep and less dreaming or REM sleep (named for rapid eye movement). Later in the night, things get more complicated.
As the alcohol clears out of the bloodstream, sleeping patterns may actually get worse, You may have trouble staying in those deeper sleep phases and spend more time in light sleep or having vivid or strange dreams in REM sleep. You might also find yourself waking up for obvious reasons like needing to go the bathroom or because you’re thirsty.
Once you’re up, you may have trouble going back to sleep. The older you are, the more your sleep may be affected. Alcohol also relaxes the muscles at the back of throat, partly blocking the airway and causing or worsening snoring. In some people it can cause or worsen sleep apnea, a serious disorder marked by loud snoring and interrupted breathing.
Sleep apnea causes restless sleep, daytime fatigue and drowsiness, even high blood pressure, stroke, and other problems. Does that mean I shouldn’t drink at night? You can still enjoy your favorite evening cocktail or cognac, just keep a few things in mind.
- Besides helping you sleep well, these tips might help you avoid a hangover the next day.
- Don’t drink to fall asleep.
- It might be tempting, especially if you having trouble falling asleep, but alcohol won’t get you the restful sleep you need.
- Instead, try getting to bed at a regular time, turning off screens early, and avoiding caffeine late in the day.
If you’re wide awake in the middle of the night, get up and read or watch TV for a bit and try again later. Take it easy. Experts define moderate drinking as one drink a day for women, two for men. (A drink is a 12-ounce beer, 5-ounce pour of wine, or 1.5-ounce shot of liquor.) This amount doesn’t seem to have a major effect on REM sleep in studies, but everyone’s different.
Does dehydration increase heart rate?
Can dehydration cause heart palpitations? – Yes. For the same reason dehydration can cause low blood pressure, it can also cause heart palpitations. Palpitations are the feeling of a pounding, fast-beating or fluttering heart. When blood volume is decreased, the heart has to beat faster to try to continue to deliver oxygen to your organs.

Easy things you can do to lower your blood pressure or help prevent high blood pressure in the first place. Beaumont Health https://www.beaumont.org/images/default-source/default-album/logo.png?sfvrsn=d43d7fef_4 High blood pressure is dangerous. It can lead to many health problems, including heart attack, stroke, heart failure, angina, coronary artery disease, peripheral artery disease, kidney disease, vision loss, sexual dysfunction and more. Fortunately, high blood pressure can often be prevented or controlled.
- Exercise, Doctors recommend at least 150 minutes per week of exercise to help reduce blood pressure. Brisk walking is excellent for reducing blood pressure and improving overall cardiovascular health, but other exercises can work too. Try jogging, riding a bike, swimming, dancing, or interval training to get your aerobic exercise. Strength training is also important to your heart health and can help reduce blood pressure.
- Eat a heart-healthy diet, Eating a well-balanced diet with lots of fruits, vegetables, whole grains, nuts, and seeds that is also low in sodium, saturated fat, added sugar, and cholesterol is important for your heart. There is a diet specifically geared toward lowering blood pressure. It’s called the DASH diet, which stands for dietary approaches to stop hypertension. Talk to your doctor or make an appointment with a dietitian if you need help making changes to your diet.
- Eat potassium- and magnesium-rich foods, Potassium can help regulate your heart rate and can reduce the effect that sodium has on your blood pressure. Foods like bananas, melons, oranges, apricots, avocados, dairy, leafy green vegetables, tomatoes, potatoes, sweet potatoes, tuna, salmon, beans, nuts, and seeds have lots of potassium. Magnesium is thought to help blood vessels relax, making it easier for blood to pass through. Foods rich in magnesium include vegetables, dairy, chicken, legumes, and whole grains. It’s better to get vitamins and minerals from food, and a heart-healthy diet like the one we described above is a good way to ensure you get plenty of nutrients. However, you may want to talk to your doctor about whether taking certain supplements might help your blood pressure.
- Reduce sodium in your diet, One easy way to reduce your sodium intake is to limit or avoid processed foods, such lunch meats, hot dogs, bacon, frozen dinners, canned vegetables with added salt, and that sort of thing. Most packaged convenience foods, like macaroni and cheese, soups, side dishes, pizzas, and other multi-ingredient foods have a lot of added sodium. Start reading labels and pay attention to the sodium content. You should aim for 1500mg or less every day.
- Limit your alcohol consumption, Drinking alcohol can raise blood pressure, and drinking more than one alcoholic beverage per day may raise your blood pressure and increase your risk for hypertension.
- Reduce the stress in your life, Long-term stress can lead to high blood pressure. There are small lifestyle changes you can make to both combat stress and to manage the effects of it in healthy ways. Exercise, eating a healthy diet, limiting alcohol and caffeine intake, practicing yoga, meditation, or deep breathing, meditating, praying, journaling, laughing, listening to music, spending time with family and friends, and playing with animals can all help reduce your stress and lower blood pressure. Learn about more tips for reducing stress.
- Eat dark chocolate, Dark chocolate and cocoa powder are both full of heart-healthy plant compounds called flavonoids. Flavonoids are good for you because they cause your blood vessels to dilate, which can help lower blood pressure. Just make sure your chocolate doesn’t have too much sugar. Choose chocolate that is at least 70 percent dark for best results. You can buy individually wrapped chocolate pieces that are the perfect size. Eat one or two a day and enjoy the delicious heart-protective effects.
- Eat berries, Berries have many health benefits, and one of them is improving blood pressure and reducing other heart disease risks. Berries, like strawberries, raspberries, blackberries, and blueberries, have lots of polyphenols, which are great for your heart. They’re also really tasty. So, load up on the berries for better blood pressure. If you don’t like eating them all the time, try adding them to a smoothie made with low-fat or fat-free yogurt without added sugar. Throw in some ice, banana, and low-fat milk for a heart-healthy treat.
- Reduce processed sugar and refined carbohydrates, Many studies have shown a link between high blood pressure and processed sugar. Even moderate amounts of sugar can raise blood pressure. For example, during the Framingham Women’s Health Study, women who drank as little as one soda per day had higher blood pressure than women who drank less. It’s not just sweet sugar that raises blood pressure. Refined carbohydrates, like white bread and pasta, covert to sugar quickly when they’re eaten, and they may also cause blood pressure to rise. There is evidence that reducing refined sugar intake can lower blood pressure and improve heart health.
- Hug people – and pets, There is evidence that hugging people can lower your blood pressure. A similar effect can occur from cuddling with pets or even just petting them.
There are other important things you can do to reduce your blood pressure and improve your health, but they may take a bit more effort than the ten things listed above. Quitting smoking and staying away from secondhand smoke is vital to your health, and it’s a great way to lower your blood pressure.
If you smoke, talk to your doctor about how to quit. Then quit. It’s one of the best things you can do to get healthy and reduce your risk of serious health problems. Another important step is to lose weight and maintain a healthy weight. Being overweight elevates your risk for high blood pressure and many other diseases and conditions.
Losing just 5 percent of your body weight can have a significant positive impact on your blood pressure. Studies have shown that the combination of exercising and losing weight improves blood pressure numbers even more than either one alone. It may seem daunting to lose weight, but it is possible.
Talk to your doctor about how other people have done it. And consider seeing a weight loss counselor too. You can do this! And after only a few pounds of healthy weight loss, you should start seeing your blood pressure numbers drop. Set small, easily attainable goals, and when you reach them, set bigger ones.
Step by step, you will take control of your health and your blood pressure. To get all of the latest health news and trends delivered straight to your inbox, subscribe to Beaumont’s HouseCall newsletter. : 10 Easy Things You Can Do to Lower Your Blood Pressure
Does less alcohol lower your resting heart rate?
8. Drink Less Going Forward – If you’re participating in an alcohol-free month this year, you’ll likely notice fairly quickly that the benefits of not drinking are reflected in your WHOOP data. Among other things, you’ll see higher HRV, lower resting heart rates, fewer disturbances in your sleep, more time spent in the restorative stages of sleep, better recoveries, and an ability to take on greater amounts of strain,
What causes low heart rate?
Bradycardia is normal for some people, especially if you’re extremely fit. However, it can also be caused by: damage to your heart due to aging or heart diseases (such as heart attack), cardiomyopathy or myocarditis. hypothyroidism.
