Moderate alcohol consumption ‘boosts immune system’

This is likely related to polyphenols in red wine and may explain why beer and spirits (hard alcohol) haven’t been linked to the same health benefits. George Koob, a behavioral psychologist and the director of the National Institute on Alcohol Abuse and Alcoholism, agrees. Still, some experts argue the immune risks don’t mean you have to quit lockdown happy hour completely. If you want to play Ina Garten and have a Cosmo, or Stanley Tucci and have a Negroni, that’s fine. Some research even suggests that a few libations — 1 drink a day for women and 2 a day for men — may even boost the immune system.

Alcohol Withdrawal Symptoms: What Does Detoxing Feel Like? A Timeline

Once you start drinking, your body has to work to metabolize the alcohol, since it considers ethanol a toxin. Stopping alcohol use can significantly improve your health, boost your immune system and protect your body from serious infections and viruses.

  • Gut microbiota can signal to the brain and liver through multiple direct and indirect mechanisms.
  • The body constantly is exposed to pathogens that penetrate either our external surface (i.e., the skin), through wounds or burns, or the internal surfaces (i.e., epithelia) lining the respiratory and gastrointestinal (GI) tracts.
  • In this interview conducted at Pittcon 2024 in San Diego, Maria Marco discusses her research on the health benefits, safety, and waste reduction potential of fermented foods, and the microbial processes involved in their production.
  • Alcohol’s effects on the structural host defense of the gastrointestinal (GI) tract.
  • Cellulitis is a bacterial infection of the skin’s deeper layers that causes pain, swelling, and, redness in the skin’s infected area.

Factors That Affect How Alcohol Affects Your Immune System

Likewise, higher pathogen burden and decreased CD8 T cell immunity was observed in female mice administered ethanol at 15% (w/v) for 5 days and challenged with Listeria monocytogenes (Gurung, Young et al. 2009). Similar results have been seen in SIV infection of male nonhuman primates (Bagby, Stoltz et al. 2003, Molina, McNurlan et al. 2006, Poonia, Nelson et al. 2006, Marcondes, Watry et al. 2008). In addition, production of IL-10 in response to TLR2/6 stimulation was increased (Pruett, Zheng et al. 2004). This same treatment also inhibited the in vitro production of IL-6 and IL-12 by peritoneal macrophages harvested 2 hours following injection of LPS (Pruett, Fan et al. 2005).

How Much Alcohol Is a Problem For Your Immunity?

Alcohol’s effects on the structural host defense of the gastrointestinal (GI) tract. Alcohol-induced changes in tight junctions cause increased intestinal leaks that lead to translocation of bacteria-derived products such as lipopolysaccharide (LPS). These molecules enter the circulation to the liver where they activate endothelial and stellate cells as well as hepatocytes, resulting in a chronic inflammatory environment aggravating organ injury.

Short-term effects of alcohol on the 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. “Alcohol intake can kill normal healthy gut bacteria, which help to promote health and reduce risk of infection,” Mroszczyk-McDonald said. Your immune system has several different cell types, each does drinking alcohol weaken your immune system of which has a different but very important job to help keep you healthy. HMGB1 can activate TLR4 and RAGE receptors alone as well as in heteromers with cytokines or chemokines. HMGB1 and HMGB1 heteromer complexes can activate essentially all TLRs,44 contributing to HMGB1 as a pro-inflammatory signal. Moderate red wine intake may lower the risk of heart disease, Type 2 diabetes, and other medical conditions.

  • Once they are at the site of infection, they swell in size and develop into the mature defensive cells—the macrophages—that enter the tissues.
  • Similar results have been seen in SIV infection of male nonhuman primates (Bagby, Stoltz et al. 2003, Molina, McNurlan et al. 2006, Poonia, Nelson et al. 2006, Marcondes, Watry et al. 2008).
  • Finally, alcohol inhibits the responsiveness of B-cells at certain developmental stages (i.e., blasts, which are the precursors to the antibody-secreting plasma cells) to various cytokines, particularly to IL-2 and IL-4.
  • Alcohol immunosuppression can cause someone to catch a simple cold easier than other people or develop a more serious condition such as cancer or septicemia.
  • Clinical and preclinical studies are currently investigating microglial and brain pro-inflammatory antagonists and offer great promise for improved AUD treatments.4 These findings suggest that AUD changes in brain networks and behavior involve HMGB1, TLRs, and other innate immune signaling molecules.
  • Though there’s still limited data on the link between alcohol and COVID-19, past evidence shows alcohol consumption can worsen the outcomes from other respiratory illnesses by damaging the lungs and gut, and impairing the cells responsible for immune function.

  • Changes in transcription are linked to increases in pro-inflammatory genes and decreases in trophic growth genes through epigenetic gene enhancers or silencers.
  • Heavy drinking is more likely to affect a person’s immune system than moderate drinking.
  • For example, depending on your level of alcohol use, quitting drinking may help resolve the first stage of alcohol liver disease.
  • Although chronic heavy drinking has harmful effects on the immune system cells at the systemic level, this review focuses on the effect produced on gut, brain and liver, because of their significance in the link between alcohol consumption, gut microbiota and the immune system.

Moderate alcohol use may not weaken the immune system, but you should be careful
