If you are drinking a lot, stopping or decreasing your alcohol use can also help your chances of not developing severe liver disease. Certain immune system cells — T cells and B cells — originate in your bone marrow. Antibodies detect and get rid of substances that are harmful to your body, including bacteria and viruses. “Drinking alcohol in large quantities even just for a short period of time — like binge drinking — can be bad for your health and your immune system,” says Favini. “If you have a family history of alcohol abuse, or are at risk, or have been an abuser in the past, we are not recommending you go out and drink to improve your immune system,” says Messaoudi.

  • Examples include certain cancers, as well as pneumonia and other respiratory problems.
  • In contrast to the inhibitory effects of acute alcohol treatment (up to 24 hours), prolonged exposure of human (men and women) peripheral blood monocytes to 25mM ethanol for 7 days increased LPS-induced TNF-α production without affecting IL-10 production (Pang, Bala et al. 2011).
  • Alcohol abuse suppresses multiple arms of the immune response, leading to an increased risk of infections.
  • Additional studies in rodents assessed the effects of alcohol on the effectiveness of bacillus Calmette-Guérin (BCG) vaccination, which protects against tuberculosis.
  • You can also ask your health insurance company for a list of in-network providers.

But if you find yourself leaning on the bottle to get you through the day, it could be worth it to head outside for a jog — exercise is a tested method of supporting the immune system — or video chat a friend instead. From March 7 to April 11, alcohol sales surged by 26 percent in the United States. People report drinking far more frequently and earlier in the day than they did pre-pandemic. We can all experience temporary and long-term effects of alcohol, depending on our consumption. Weekly intimacy seems to help boost your immune system compared to those who have it less often. Sex raises levels of a germ-fighting substance called Immunoglobulin A, or IgA.

Opposing Effects of Alcohol on the Immune System

When the body detects a threat—such as pathogens (e.g., bacteria, viruses), chemical irritants, or damaged tissues from injury—it initiates an inflammatory response to eliminate the threat and promote healing. Sunlight may energize special cells in your immune system called T-cells that help fight infection. Many plants in the woods make phytoncides and other substances you breathe in that seem does alcohol suppress immune system to bolster your immune function. Alcohol feeding suppresses the production and secretion of certain acute-phase proteins (i.e., type II cell surfactant). This effect may contribute to lung injury in response to inflammation (Holguin et al. 1998). Monocytes express Toll-like receptor (TLR) 4, the PRR that is often responsible for recognizing LPS on the surface of Gram-negative bacteria.

In contrast, mice that consumed ethanol after the BCG vaccination were protected against a subsequent M. Taken together, these data suggest that chronic ethanol exposure interferes with immunity to new antigens but not with immunity established before alcohol consumption. These foods may help your body make more of the white blood cells you need to fight off infections. Fresh produce and nuts and seeds pack a lot of zinc, beta-carotene, vitamins A, C, and E, and other nutrients you need for a healthy body. Plant-based foods also fill you up with fiber, which helps lower your body fat percentage, which can strengthen your immune response. Vitamin E is one of the most effective antioxidants and its deficiency exacerbates freeradical damage impairing the ability of T cells to respond to pathogenic challenge (Mocchegiani, Costarelli et al. 2014).

Impact of Chronic Inflammation on Health

“Alcohol temporarily dampens anxiety, negative emotions, and other uncomfortable feelings, but the relief is short-lived and negative emotions tend to increase when the buzz wears off,” Koob says. The change in emotions a person experiences between intoxicated and being sober can also motivate drinkers to drink more frequently, Koob explains. George Koob, a behavioral psychologist and the director of the National Institute on Alcohol Abuse and Alcoholism, agrees. “Even short-term alcohol misuse affects the immune system,” Koob tells Inverse.

  • Several lines of evidence suggest that alcohol abuse significantly disrupts the GI and respiratory tract immune barriers.
  • Reduced IgE levels were also observed and may be related to the observed decrease in IgE synthesis regulators, IL-13 and CD40 ligand.
  • Particularly important are the epithelial immune barriers of the reproductive, GI, and respiratory tracts.
  • These different layers of interaction make validation of the mechanisms by which alcohol affects immune function challenging.
  • VDR normally reduces expression of a signaling molecule called renin angiotensin (RAS) (Li et al. 2004).

Impairment in T-cell recruitment also was observed in mouse models of chronic alcohol exposure. Despite reduced B-cell numbers, people with AUD exhibit increased serum concentration of IgA, IgG, and IgE. This increase in circulating Igs correlates with increased levels of antibodies directed against liver antigens and byproducts of oxidative damage. Finally, alcohol exposure in utero significantly interferes with the development of T cells and B cells, which ultimately might increase risk for infections during adulthood. In contrast to the devastating effects of chronic alcohol abuse, a few studies have shown that moderate alcohol consumption increases the number of T cells; improves T-cell cytokine production; and enhances immune response to vaccines in humans, nonhuman primates, and rodents.

Which Health Risks Are Associated with a Weakened Immune System?

Recently, it was reported that a single episode of binge alcohol consumption in alcohol-experienced human volunteers (men and women) initially (within the first 20 min) increased total number of peripheral blood monocytes and LPS-induced TNF-α production when blood alcohol levels were ~130mg/dL. However, similarly to the in vitro studies described above, at 2 and 5 hours post-binge the numbers of circulating monocytes were reduced and levels of antiinflammatory IL-10 levels were increased (Afshar, Richards et al. 2014). Clinicians have long observed an association between excessive alcohol consumption and adverse immune-related health effects such as susceptibility to pneumonia. The effects of alcohol on both cell-mediated and humoral immunity have been well-documented since the early 1960s, wherein researchers found that alcohol abuse significantly reduced both CD4 and CD8 T-cell counts. The innate cellular response, which is mediated primarily by monocytes/macrophages and neutrophils, involves the recognition, phagocytosis, and destruction of pathogens—processes essential to subsequent adaptive responses.

does alcohol lower your immune system

Past research shows alcohol consumption leads to more severe lung diseases, like adult respiratory distress syndrome (ARDS) and other pulmonary diseases, including pneumonia, tuberculosis, and respiratory syncytial virus. The spike in alcohol sales has alarmed health experts and officials around the world, who are concerned that increased drinking could make people even more vulnerable to the respiratory disease. According to Favini, a moderate amount of drinking — one drink per day for women, and two drinks per day for men per the United States Dietary Guidelines for Americans — is generally safe for people in good health and unlikely to have a negative effect on their immune systems. Healthy habits, such as being active, eating a balanced diet, and getting enough sleep, can keep your immune system strong. But unhealthy factors, like stress, smoking, or drinking alcohol, can be taxing for your immune system and make it harder for it to fight off infection. The pancreas helps regulate how your body uses insulin and responds to glucose.
