Like many people, you may still want to enjoy alcohol without compromising your immune system. For more information about alcohol’s effects on the body, please visit the Interactive Body feature on NIAAA’s College Drinking Prevention website. Your best bet is to limit your overall alcohol intake and be aware of the ABV and added sugar content of the alcohol you’re consuming. Manaker also recommends getting seven to nine hours of quality sleep and managing your stress through techniques like yoga, meditation and deep-breathing exercises.

does alcohol weaken your immune system

The researchers reported significant reductions in the TNF-α levels three and six hours after the alcohol consumption. The innate immune response to a pathogen is followed by an adaptive immune response that is activated only after the body is exposed to the pathogen for the first time and which is specific to that one pathogen. Decreased IL-2 and CCL5 levels provide insight into possible mechanisms of impaired T cell recruitment and proliferation. Increases in IL-7 and IL-15, which are critical for T cell survival, may be compensatory mechanisms for reduced IL-2 levels.

Neuroimmune Function and the Consequences of Alcohol Exposure

Similarly, an increased percentage of CD8 T cells expressing HLA-DR and CD57 was reported in the group of male alcoholics with self reported average alcohol consumption of approximately 400g/day for approximately 26 years (Cook, Ballas et al. 1995). Taken together, these studies suggest that chronic alcohol-induced T cell lymphopenia increases T cell activation and homeostatic proliferation resulting in increased proportion of memory T cells relative to naïve T cells. Several lines of evidence suggest that alcohol consumption exerts a dose-dependent impact on the host response to infection.

In addition, they can excrete toxic substances from their granules that can kill pathogens. PMNs produce a host of bacteria-killing (i.e., bactericidal) molecules (e.g., myeloperoxidase, defensins, azurophil-derived bactericidal factors, bactericidal permeability-increasing protein, cationic proteins, gelatinase, and lactoferrin). In addition, PMNs participate in the regulation of the local defense response by releasing signaling molecules called cytokines and chemokines (e.g., tumor necrosis factor [TNF]-α; interleukin [IL]-1β, IL-6, and IL-8; and macrophage inflammatory protein [MIP]-2). These molecules help recruit and activate additional PMNs as well as macrophages to the site of an injury or infection. For instance, IL-1 induces HPA axis activation and glucocorticoid release that suppresses the immune system (Sapolsky, Rivier et al. 1987). Cytokines are also proposed to cross the blood-brain barrier and produce sickness behavior (Watkins, Maier et al. 1995), which is comorbid with AUD (Dantzer, Bluthe et al. 1998).

Blood Alcohol Concentration: What to Know About Alcohol Levels

It’s also worth noting that the recommended maximum above is for each day you choose to drink. The maximum for recommended drinks isn’t cumulative; it’s still unsafe to binge drink on the weekend even if you didn’t drink earlier in the week, for example. One of the main ways alcohol can impact your body is by contributing to inflammation. Learn the connection does alcohol weaken your immune system between alcohol and inflammation, how to reduce chronic inflammation, and how much alcohol is generally safe to consume without triggering inflammation. Fortunately, not drinking for 30 days can bring T cell counts back to normal levels. Overall, avoid drinking more than moderate amounts if you want your immune system in good shape, says Favini.

  • Additionally, the role of alcohol-induced changes in the microbiome on immunity should be studied.
  • For instance, increased morbidity and mortality, pulmonary virus titers, and decreased pulmonary influenza-specific CD8 T cell responses were reported in female mice infected with influenza that consumed 20% (w/v) ethanol in their drinking water for 4–8 weeks (Meyerholz, Edsen-Moore et al. 2008).
  • “When you’re feeling run down or like you might get sick, you want to be well hydrated so that all the cells in your body have enough fluid in them and can work really well,” Favini says.
  • Despite these observations, which shed some light on alcohol’s effects on B-cells and their functions, some questions remain to be answered.

Indeed, some studies have even suggested that moderate alcohol consumption is good for us. Alcohol can also affect the upper respiratory system, impairing the function of immune https://ecosoberhouse.com/ cells in the lungs. This can often remain undetected until a more serious respiratory problem occurs, then frequent drinkers get it worse than those who don’t drink.
