Moderate Drinking May Boost Immunity

But drinking too much—on a single occasion or over time—can have serious consequences for our health. For it to function normally, it needs to collaborate with other body parts, organs, and cells—therefore not everyone might experience the benefits of moderate and intermittent alcohol drinking. Deciding how much, if any, alcohol is right for you can be complicated. A damaged pancreas may also prevent the body from producing enough insulin to utilize sugar.

Research shows that healthy people who drink moderate amounts of alcohol may have a lower risk of developing coronary heart disease than nondrinkers. Those chemicals include recreational drugs as well as prescription drugs, such as your HIV medications. But these studies looked at the association between alcohol and colds. Long-term, heavy drinking causes alterations in the neurons, such as reductions in the size of brain cells. Individuals infected with HIV are at risk of contracting other, life threatening diseases because the virus weakens a persons immune system. This is one of the reasons it’s hard to get a good night’s sleep after drinking.

His team discovered that blocking an antibacterial receptor on monocytes in the brain stopped mice being so clumsy when exposed to alcohol.

Individuals who consume alcohol regularly and at higher levels than the liver can process it shows increased levels of immunoglobulins within their bloodstream, indicating an autoimmune response. Alcohol disturbs this pacemaker system and causes the heart to beat too rapidly, or irregularly. It has been suggested that people who consume large amounts of alcohol have an 83% increased risk of getting community-acquired pneumonia compared to their moderately-drinking counterparts. The researchers isolated immune cells from the blood sample, and then measured their response to introduced proteins from potentially harmful bacteria, New Scientist explains. Finally, genetics may play a role in preventing some heavy drinkers from developing cancer. It also affects the respiratory system. If you’re feeling lonely, find a new sense of purpose in life by volunteering your time, caregiving, or immersing yourself into a new community activity. This does not mean that anyone who drinks too much will develop cancer.

  • Damage to the cerebellum results in a loss of balance and stumbling, and also may affect cognitive functions such as memory and emotional response.
  • An abundance of cytokines can damage your tissues, whereas a lack of cytokines leaves you open to infection.

Using brain imaging and psychological tests, researchers have identified the regions of the brain most vulnerable to alcohol’s effects. The collective results of these studies clearly demonstrate that the more you drink, the higher your risk for developing a variety of cancers. Heavy drinking—even for just a few days at a time—can cause fat to build up in the liver. Asynchrony with circadian rhythms can cause annoying yet minor problems like jet lag, but it can also increase the risk of more serious problems like cardiovascular disease and diabetes. Seven months later, the researchers reinoculated the monkeys with the same vaccine.

  • Authors of that study recommended that “men who plan to father children stop drinking alcohol at least three months before engaging in sexual intercourse that may lead to pregnancy.
  • Drinking large amounts of alcohol can also increase a person’s risk of stroke by contributing to high blood pressure, diabetes, obesity and other medical conditions that can cause a stroke.
  • The involvement of both mechanisms is highly likely since chronic binge drinking has been shown to impair activation of granulocyte precursor cells in response to bacteremia in mice52.
  • “The immune system has a type of memory, where if it sees what it’s been immunized against, it will mount an antibody response,” said Kathy Grant, a coauthor and behavioral neuroscience professor at Oregon Health & Science University.


Women also show liver damage more quickly than men. Although the information was obtained from sources believed to be reliable, MedLink Corporation, its representatives, and the providers of the information do not guarantee its accuracy and disclaim responsibility for adverse consequences resulting from its use. Upper and lower respiratory tract infections. They also call on more white blood cells to swarm an infected area. There are small studies that suggest a benefit to some of these foods, but strong evidence is lacking. A variety of complications, including jaundice, insulin resistance and type 2 diabetes, and even liver cancer, can result as cirrhosis weakens liver function.

And factures may heal more slowly. This stems from the toxicity of alcohol to immune system cells (dendritic cells). Good sleep hygiene is going to sleep and waking up at the same times every day.

  • These tests demonstrate how alcohol affects emotions and personality, as well as how it compromises learning and memory skills.
  • However, these studies stimulated human PBMC or THP1/RAW cell lines with LPS for various durations in the presence of different amounts of ethanol and measured canonical LPS inducible cytokines as readouts.

This severe form of liver damage can be life threatening and develops in 10 to 20 percent of heavy drinkers. Half of the cells were also exposed to alcohol levels equivalent to a week of heavy drinking.

Other common foods touted for their immune-boosting properties are ginger, citrus fruits, turmeric, oregano oil and bone broth. Although the first study was made in animals, and the second in humans, the results suggest that the effect of alcohol intake on T lymphocyte subsets may depend on the amount consumed. The immune system may be harmed directly by intoxicating substances, or the way the drug is ingested may contribute to a higher risk of infection, coupled with a lower immune response. 6 fluid ounces or 14 grams of pure alcohol.

A recent study shows that slower inflammatory cytokine production can reduce your ability to fight off infections for up to 24 hours after getting drunk.

In reviewing the literature, it is important to realise that other factors, unrelated or indirectly related to immune function, such as drinking pattern, amount of alcohol, beverage type or gender differences, are directly implicated in the relationship between alcohol consumption and the immune system10–13 (Fig. )There was an increase in total circulating leukocytes, monocytes, and natural killer cells. Numerous studies have found a link between excessive alcohol consumption and immune function. Chronic alcohol use also suppresses the development of T-cells and may impair the ability of NK cells to attack tumor cells. They were vaccinated again after seven months. Luckily, our immune system is designed to protect our bodies from the scores of foreign substances that can make us sick. The researchers focused their attention on the immune receptor Toll-like receptor 4 (TLR4).

Chronic drinking alters transcriptional profiles of resting PBMC independent of ethanol dose

This is because the chemicals in the brain associated with deep sleep are also the ones that tell your body to stop producing stress hormones. Ulcers can be fatal if not diagnosed and treated early. HIV develops faster in chronic drinkers who already have the virus. Such symptoms usually disappear, however, after several weeks of sobriety. Alcohol depresses the cerebral cortex, the wrinkled and folded outermost layer of the brain that controls language and thinking, clouding your judgment and thinking. If you or someone you love is struggling with alcohol addiction or mental illness, we can help. Without these inflammatory responses, your body’s ability to defend itself against bacteria is significantly reduced. The formation of scar tissue destroys the liver.

The limbic system, which regulates emotions, also goes haywire, resulting in exaggerated emotions.

We've crunched the numbers and here are the results. Sitting down for long periods of time has been linked to diabetes, heart disease, cancer, and early death. The immune system was revving up: Multiple studies have confirmed that alcohol impairs the body’s neutrophil response, making it difficult to fight off pneumonia and heightening the risk of death as a result. These effects occur when caffeine is consumed in moderation. One way that alcohol interacts with the body’s natural balance to create immune-damaging effects is by wreaking havoc on the digestive system. “But there is less awareness of alcohol’s harmful effects in other areas, such as the immune system,” Loyola University Chicago’s Elizabeth Kovacs says in a news release. While a single drinking binge will not automatically lead to pancreatitis, the risk of developing the disease increases as excessive drinking continues over time.

Some harm done to the immune system or other body systems may be reversed when the person becomes sober, so prompt treatment is key. This can lead to Wernicke-Korsakoff syndrome, a brain disorder that affects memory. For example, in the case of pneumonia, the body’s natural response to the first sign of this infection is to deploy neutrophils, cells that fight bacteria-induced inflammation. These conditions are extreme; however, several other, more common issues, can arise when immune function is impaired due to alcohol consumption such as:

3/4 Questions

Nicotine increases cortisol levels, while reducing B cell antibody formation and T cells’ response to antigens, explains Dr. More than 2 million Americans suffer from liver disease caused by alcohol. As we recently reported for gene expression changes of resting PBMC isolated from CHD female rhesus macaques46, additional mining of data using online databases suggested that that a majority of these transcriptional triggers in PBMC from both CMD and CHD originate from DCs and monocytes. While many of us recognize that excessive alcohol consumption can lead to liver disease, we might not know why. Previous studies in both humans and animals revealed that alcohol intoxication exerts effects on the immune system several hours to days after the exposure—when blood alcohol is no longer detectable.

Alcohol also alters the muscular contractions of the small and large intestine, causing diarrhea and even intestinal bleeding. It can help guard against heart attack and stroke by preventing blood clots from forming and by dissolving blood clots that do develop. For decades, researchers have known of the correlation between increased rates of certain cancers and problem drinking, but the mechanism by which alcohol causes cancer was not known. Long-term alcohol use may prevent your body from keeping your bones strong. The effects on the immune system may be due not only to the small amount of alcohol but also to the antioxidants and other components in these types of beverages.

These are proteins that target specific antigens and then remember how to combat the antigen.

Brain and Nervous System

Because the liver plays such a vital role in alcohol detoxification, it is especially vulnerable to damage from excessive alcohol. It’s possible that moderate drinking could produce the same effect in humans. The gut is the first area where alcohol really starts to interact with the body and make contact with the bloodstream. It’s possible moderate drinking in humans may also enhance the immune response to vaccines and viral infections. Food allergens. Alcohol also causes an increased release of serotonin, another neurotransmitter, which helps regulate emotional expression, and endorphins, which are natural substances that may spark feelings of relaxation and euphoria as intoxication sets in.

Kirkpatrick cites a 2020 study that showed that alcohol overexerts immune pathways, which in turn decreases the body’s ability to defend against a number of adverse invaders. Some people are more susceptible to the disease than others, but researchers have not yet identified exactly what environmental and genetic factors play the biggest role. Moreover, Estruch and co-workers33 found an additional anti-inflammatory effect by decreasing C-reactive protein (CRP), as well as monocyte and endothelial adhesion molecules, after 28 days of red wine intake compared to gin with the same amount of ethanol (30 g per day). Cigarette smoking, obesity, and poor nutrition all contribute to alcoholic liver disease. Introducing alcohol into the digestive system disrupts this balance and damages the cells that build a barrier between your gut and the rest of your body. Once in the bloodstream, alcohol will reduce the white blood cell count in the body. A stroke occurs when blood cannot reach the brain.

Because the immunity of the mucus is impaired in both the lungs and digestive tract, any disease can become more severe.

Research has shown that heavy drinking can cause changes in the immune system that can lead to numerous serious and even fatal problems.
