Detrimental Effects of Alcohol-Induced Inflammation on Brain Health: From Neurogenesis to Neurodegeneration Cellular and Molecular Neurobiology

Moderate drinking equates to two drinks a day for men and one drink a day for women. More than this is considered excessive and may cause damage to the immune system. However, individuals with existing health conditions such as heart disease, chronic illness, asthma or diabetes should avoid consuming alcohol. In addition to these changes in cytokine function, investigators also have shown a contribution of barrier dysfunction to the postinjury increase in infections in intoxicated people (Choudhry et al. 2004). Thus, alcohol intoxication can suppress chemokine production and impair the expression of proteins that allow neutrophils to adhere to other cells at the site of infection, which also contributes to increased susceptibility to infection.

  • Your body releases certain proteins that help the immune system, called cytokines, only during sleep.
  • The connection between alcohol consumption and your digestive system might not seem immediately clear.
  • In addition, oxidation of ethanol by CYP2E1 leads to the formation of reactive oxygen species (ROS).

Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes. Each of those consequences can cause turmoil that can negatively affect your long-term emotional health. Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe. “The good news is that earlier stages of steatotic liver disease are usually completely reversible in about four to six weeks if you abstain from drinking alcohol,” Dr. Sengupta assures. Heavy drinking can also lead to a host of health concerns, like brain damage, heart disease, cirrhosis of the liver and even certain kinds of cancer.

Does Alcohol Kill Germs?

On a smaller scale, large quantities of alcohol can also prevent the immune system from fighting off common viruses, such as the common cold. “After an episode of binge drinking, the ability of the innate immune system — the first line of defense in the body for detecting and destroying foreign invaders — to fight infections is reduced,” Koob says. Dipak Sarkar, an expert on alcohol metabolism and immunity, and professor at Rutgers University, tells Inverse that he advises skipping alcohol altogether during the Covid-19 pandemic. This is because studies suggest that heavy drinking — defined as over 8 drinks per week for women and 15 per week for men — can disrupt key immune pathways, make people more susceptible to infection, and weaken the immune system. The effect of beer on the immune system may not be as significant as the effect of stronger alcoholic beverages, but it’s important to remember that beer and wine can cause adverse health effects and even suppress the body’s immune response in excessive amounts.

  • Thus, alcohol intoxication can suppress chemokine production and impair the expression of proteins that allow neutrophils to adhere to other cells at the site of infection, which also contributes to increased susceptibility to infection.
  • This defect was rescued when cultures were treated with the Rho kinase inhibitor, Y27632 indicative that ethanol reduced efferocytosis through the induction of Rho kinase activity in a dose-dependent manner (Boe, Richens et al. 2010).
  • Such studies can be challenging to conduct in humans because of difficulties in obtaining accurate medical histories, maintaining adherence, confounding factors such as diet, sleep-wake cycles, and ethical considerations when studying large doses of ethanol.

Alcohol has a broad range of effects on the structural, cellular, and humoral components of the immune system. To elicit a response from the cell-mediated arm of the adaptive immunity, antigens need to be presented to the CD4+ and CD8+ T-cells. Studies in rodents found that chronic alcohol feeding can impair presentation of protein antigens in the spleen (Mikszta et al. 1995).

How alcohol affects the innate immune system

However, women who drink more than two drinks on one occasion and men who drink more than three drinks on one occasion may experience more health complications due to their excessive alcohol consumption. The impact alcohol has on the body is mainly due to the way the body processes alcohol. Factors such as the amount of alcohol a person drinks, how often a person drinks, the type of alcohol they drink, and whether they are biologically male or female can increase or decrease how much it affects their immune system. Alcohol can hinder the body’s ability to recover from tissue injury and heal infections.

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. Chronic drinking — for 12 to 15 years — can lead to a reduction in the number of T cells. Extremely heavy drinking — about 30 drinks per day — can throw off the balance of immune system cells. Before you decide whether to pour a glass, it’s worth understanding how alcohol influences the immune system — as well as taking the time to reflect on your own relationship with alcohol. Alcohol does affect your ability to stay healthy, but that’s also dependent on how much you’re drinking.

How Does Alcohol Consumption Affect the Immune System?

There are also many other factors that can affect your immune health that aren’t related to hygiene. Rarely, severe pain after drinking alcohol is a sign of a more serious disorder, such as Hodgkin’s lymphoma. does alcohol weaken your immune system Having a mild intolerance to alcohol or something else in alcoholic beverages might not require a trip to a doctor. Simply avoid alcohol, limit how much you drink or avoid certain types of alcoholic beverages.

  • A lung abscess can lead to cough, chest pain, fever, fatigue, night sweats, appetite loss, weight loss, sputum, and, empyema.
  • An army of antibodies — Another subsystem of the immune system is called adaptive immunity.
  • There is some evidence that sorrow, especially if lasts a long time, can depress your body’s immunity.
  • Alcohol’s widespread effects on immune function also are underscored in the article by Gauthier, which examines how in utero alcohol exposure interferes with the developing immune system in the fetus.

Overall, avoid drinking more than moderate amounts if you want your immune system in good shape, says Favini. And if you feel like you’re coming down with something or are sick, do not drink. Not only will drinking alcohol reduce your immune system’s strength, but alcohol also has a dehydrating effect. Moreover, some people shouldn’t drink at all, according to the Dietary Guidelines. This includes people who are pregnant, have alcohol abuse disorder, or are taking medications that interact with alcohol. The immune system is how your body defends itself from infections — like harmful bacteria and viruses — and prevents you from getting sick.

Alcohol and the Innate Immune Response

Their article also highlights how the combined effect of alcohol and injury causes greater disruption to immune function than either challenge alone. Each of these events is mediated by the activation of nuclear factor kappa B (NFκB), which can be inhibited by alcohol consumption and thus prevent the production of pro-inflammatory cytokines. In vivo studies have confirmed that binge drinking with a blood alcohol concentration (BAC) of approximately 0.4% can reduce the production of various inflammatory cytokines including interleukin-6 (IL-6), IL-10, and IL-12. According to the CDC, moderate drinking is generally safe for healthy individuals of legal age.
