Effects of alcohol on sleep and nocturnal heart rate: Relationships to intoxication and morning‐after effects PMC

how alcohol affects the heart rate

During the night, alcohol decreased total sleep time, sleep efficiency, and percentage of time spent in REM stage sleep and increased nocturnal HR. The increase in nocturnal HR was consistent with an alcohol‐induced state of hyperarousal during the night, although other measures did not support this idea, such as sleep latency or arousal index. The acute subjective sedative effects of alcohol were related to increases in N2 stage sleep, but not to other disruptions in sleep or nocturnal cardiovascular function. The morning after alcohol administration, subjects reported increases in negative, low arousal states and feeling sedated, decreased urge to drink and, unexpectedly, improved digit span performance. Impairments in sleep and nocturnal cardiovascular function were not related to mood or task performance the morning after. Thus, although alcohol produced its expected acute effects, including elevated nocturnal cardiovascular activity, these were not related to residual morning‐after effects.

Healthy men and women aged 21–45 years were recruited from Michigan Technological University, Montana State University and surrounding communities. Inclusion criteria were body mass index (BMI) 18.5–35 kg/m2 and at least one self‐reported binge drinking episode (i.e., 4–5 drink equivalents within 2 h) within the past 6 months. We only included women who reported a normal menstrual cycle (i.e., 25–32 day average), were not pregnant, breastfeeding, or using hormonal contraceptives. Of course, it’s worth noting that the deleterious effects of alcohol are not a result of the occasional beverage. In simple terms, the more you drink, the harder your heart must work to overcome the amount of alcohol you’re consuming. This is why binge drinking can lead to not only an increased heart rate but an irregular heartbeat as your cardiovascular system works harder and harder to keep pace.

How can drinking alcohol affect the gut?

This study examined the effects of a high dose of alcohol on subjective and psychomotor measures, cardiovascular function, sleep quality, and morning‐after mood and behavior in healthy adults. We hypothesized alcohol‐induced disturbances in cardiovascular and sleep function during the night would predict morning‐after mood states and behavioral performance. Immediately after consumption, it increased ratings of low arousal negative, high arousal positive, urge to drink and sedation, and it impaired psychomotor performance.

The acute sedative‐like effects of alcohol were related to increases in N2 sleep, but not to other disruptions in sleep or nocturnal heart rate, and neither sleep impairments nor nocturnal heart rate were related to mood or task performance the morning after. Alcohol consumption produces feelings of well‐being and stimulation, but also impairs psychomotor performance, disturbs cardiovascular function and sleep, and can disrupt next‐day mood and behavior. A deeper understanding of how the acute effects of alcohol relate to its sleep and morning‐after effects is needed to minimize harm resulting from its use. This study examined relationships between the effects of a high dose of alcohol on subjective and psychomotor measures, nocturnal heart rate, sleep quality, and morning‐after mood and behavior. We hypothesized that alcohol would produce disturbances in cardiovascular and sleep regulation during the night, which would predict morning‐after mood and behavioral performance. Alcohol produces arousal and stimulation, but also impairs psychomotor performance, disturbs cardiovascular function and sleep, and disrupts next‐day mood and behavior.

The men consumed, on average, 361 (245) g of alcohol per week (median 378 g, range 0–840 g). The mean period of time from their last drink to when the ambulatory ECG monitor was removed was 18 (10) hours (range 4–42 hours). The amount of alcohol that the subjects consumed during their last drinking session before removal of the ECG monitor was 52 (32) g (range 0–140 g). Although past studies have shown some heart benefits of moderate drinking, research hasn’t shown a definitive link between alcohol and better heart health. You can effectively lower your heart rate by being conscious of adequately hydrating your body while drinking or after drinking alcohol.

  1. Luckily, there are plenty of ways to lower your heart rate that can be done in both the near and long term.
  2. “Take steps to lower cholesterol, control high blood pressure, get enough physical activity, stay away from tobacco and excessive amounts of booze, and follow a healthy diet.
  3. Binge drinking, or having more than five drinks in a row, also makes getting AFib more likely.
  4. As a result, you might notice you speak and move more slowly, but the effects of alcohol go deeper.

In a sample of healthy adult alcohol drinkers, we examined relationships between the acute effects of alcohol, nocturnal heart rate, sleep quality and morning‐after mood and behavior. During sleep, alcohol increased heart rate and decreased sleep quality, yet modest morning‐after effects were detected. Neither sleep quality nor nocturnal heart rate were related to either acute or morning‐after effects of alcohol. Neither the effects of alcohol on nocturnal cardiovascular function nor sleep were related to morning‐after alcohol effects.

“Some juices that may help lower blood pressure, including beetroot juice and pomegranate juice,” Manaker says. For context, beets are a great source of folate, a key vitamin essential for blood health recommended by cardiologists. A significant part of the problem, Dr. Steinbaum says, is that many people do not consume enough water when drinking alcohol. “If your heart rate increases after drinking, it is most likely due to dehydration,” she explains.

What are the health risks of abnormal heart rhythms?

If you drink, you should also make an effort every day to protect and support your heart health, like eating right and getting enough exercise. An abnormal heart rhythm isn’t always a sign of something serious, but it can be very uncomfortable. What’s more, that second drink increases activity in the sympathetic nervous system and also increases the amount of blood moving through the heart.

Direct effects of alcohol

Should a piece of this plaque (fat) break off, a clot can form around the heart and result in a heart attack. Thirty‐one men and women participated in two overnight laboratory visits during which they consumed either alcohol (1.0 g/kg for men, 0.85 g/kg for women) or placebo (randomized, crossover design). They consumed the beverage from 8 to 9 pm, and remained in the laboratory overnight for polysomnographic sleep recording. Subjective and behavioral measures were obtained during consumption and at 7–8 am the morning after.

Doctors believe booze disrupts your heart’s natural pacemaker — the electrical signals that are supposed to keep it beating at the right pace. Another way to help slow down your heart rate is to practice stress-relieving activities. You can also try meditation, which can cause your heart to slow dramatically, even going beyond the point of a resting heart rate to the pace typically only experienced while sleeping. All types of alcohol are addicting, and it’s not always possible to quit on your own. Having a drink every once in a while is not a big deal, but if you find that your drinking is starting to get out of control, it’s time to reassess your circumstances.

The digit span task is a working memory task that consists of visual presentation of a series of numbers, one at a time. After the series of numbers is displayed, the participant must respond by typing the numbers in the same in order in which they appeared. The number of digits displayed is increased by one digit every two trials beginning at 3 digits, up to a maximum of 10.

And sure, we’ve all had a night 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. 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.

The condition is estimated to affect 12.1 million people in the United States by 2030. Studies have linked higher alcohol consumption to an increased risk of AFib. Common symptoms can include heart palpitations, fatigue, or even chest pain after drinking alcohol.

On average, a regular heart rate is about 60 to 100 beats per minute when your body is at rest. But alcohol can lead to your heart rate temporarily jumping up in speed, and if it goes over 100 beats per minute, it can cause a condition called tachycardia. Too many episodes of tachycardia could lead to more serious issues like heart failure or going into irregular rhythms, which can cause heart attack and stroke. In conclusion, the results of the present study suggest that the association between alcohol intake and decreased heart rate variability may be mainly secondary to an increase in heart rate rather than a central or peripheral effect of alcohol on cardiac vagal nerve activity.

“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. If you’ve been drinking, it’s not necessarily abnormal for your heart to beat faster. However, if you come to a point where you realize your alcohol intake has led to an uncomfortable change in your heart rhythm or how you feel overall, you might be dealing with a more serious issue.
