“Those at increased risk should cut down or abstain from alcohol because every little thing an individual can do to improve the health and reduce risk is worth it at this point, even if the evidence is not entirely clear,” Mroszczyk-McDonald said. “Alcohol intake can kill normal healthy gut bacteria, which help to promote health and reduce https://ecosoberhouse.com/ risk of infection,” Mroszczyk-McDonald said. Soon after, the World Health Organization (WHO) also suggested that people cut back on drinking, since alcohol can increase the risk of experiencing complications from COVID-19.
Alcohol, other drugs, and health: Current Evidence
Understanding the role alcohol plays in our lives can help us make more does alcohol lower immune system informed decisions about our consumption. “Alcohol damages the ability of your immune system to fight viral infections. In fact, both the Surgeon General and the World Health Organization advise anyone at high risk for COVID-19 to avoid alcohol because it increases your risk for infection.” The adaptive immune system can be further subdivided into cell-mediated immunity and humoral immunity. Whereas T-cells are primarily involved with cell-mediated immunity, B-cells play a major role in humoral immunity. But drinking can weaken this system, leaving us vulnerable to infections and diseases.
Autoimmune Diseases
Moderate alcohol consumption is generally defined as up to one drink per day for women and up to two drinks per day for men. This recommendation takes into account factors such as the risk of infection, blood alcohol concentration, and the dose-dependent manner in which alcohol affects the body. It aligns with guidelines that consider the impact of drinks per day on various aspects of health, including mental health services administration. When we consume alcohol, it gets metabolized in the liver, where it can influence immune function. Studies have shown that even moderate alcohol consumption can lead to a decrease in the effectiveness of the immune response.
Can drinking raise my blood pressure?
These observations suggest that immune defects seen in individuals with AUD could also be mediated by nutritional deficiencies in addition to barrier defects and functional changes in immune cells. However, the contributions of each of these changes to increased susceptibility to infection in individuals with AUD remain to be determined. 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.
Chronic alcohol intake damages organs, particularly the liver, which plays a vital role in supporting immunity. The function of the epithelial cells, essential for barrier function, is inhibited. Persistent alcohol use elevates the risk of cardiovascular diseases, weakens cell-mediated immunity, and increases the risk of infections. It’s easy to overlook the effects of alcohol on our health amid social gatherings and celebrations. Yet, research increasingly suggests that even Substance abuse moderate drinking can impair our immune defenses, making us more susceptible to infections and diseases. In fact, studies have shown that alcohol consumption, whether in excess or moderate amounts, can disrupt immune function in various ways.
- In addition to its adverse effects on GI functioning, the impact of alcohol on the GI microbiome can also alter the maturation and functions of the immune system.

Immune System Recovery After Drinking
Gut barrier damage can make the body more vulnerable to food poisoning, and epithelial cell damage can hinder the intestines’ ability to absorb nutrients. When the gut barrier cannot function properly, harmful bacteria can leak into the bloodstream, leading to further complications. In practical terms, this means that after a night of drinking, our body may be less capable of fighting off infections. This is particularly concerning during cold and flu season, when our immune systems need to be at their best. To fully grasp how alcohol impacts our immune system, we first need to understand how this intricate system functions.
Mounting evidence links alcohol with cancer. Defining a “safe” amount of drinking is tricky — and controversial.

Heavy drinking can also cause problems well beyond the health of the drinker — it can damage important relationships. It’s all too common that problem drinking disrupts bonds with a spouse, family members, friends, coworkers, or employers.
Increased risk of cancer
Understanding the broader implications of alcohol on health can help us appreciate its effects on the immune system. For instance, individuals with pre-existing conditions like diabetes or heart disease may face even greater risks when consuming alcohol. These conditions can further compromise immune function, making it essential to consider the cumulative effects of alcohol and chronic health issues. While occasional drinking may have temporary effects, chronic alcohol consumption can lead to more severe and lasting damage to the immune system. Several studies have also shown that the lungs are highly vulnerable to the effects of alcohol. For example, alcohol can reduce the ability of respiratory epithelium cells to remove mucous from the lungs, which can directly damage lung tissue and weaken the proper functioning of the lungs over time.
The Effects of Alcohol on the Immune System
- Alcohol can disrupt the gut microbiome—the diverse community of microorganisms in our intestines that play a vital role in digestion and immune function.
- In this post, we will delve into the relationship between alcohol and immune function, exploring both short-term impacts and long-term consequences.
- If you or a loved one needs help with alcohol addiction, Gateway Foundation can help.
- Years of excessive alcohol intake can overwhelm and permanently damage immune defenses, making full recovery unlikely.
- Those studies showed decreased cytolytic activity of NK cells in C57BL/6 mice consuming 20 percent ethanol for 4 weeks; however, no differences existed in the metastasis of B16-BL6 melanoma cells in alcohol-consuming and control animals (Meadows et al. 1993).
Abstinence partially restored antibody responses against hepatitis antigens in a mouse model (Encke and Wands 2000). As reviewed by Szabo and Saha, alcohol’s combined effects on both innate and adaptive immunity significantly weaken host defenses, predisposing chronic drinkers to a wide range of health problems, including infections and systemic inflammation. 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. This exposure increases a newborn’s risk of infection and disease; additional evidence suggests that alcohol’s deleterious effects on immune development last into adulthood. Male rats on a liquid diet with 35% of calories coming from ethanol also showed enhanced mRNA half-life and protein expression of LPS-induced TNF-α by increasing TNF-α in liver monocytes/macrophages (Kishore, McMullen et al. 2001).
In addition, such studies could reveal the pathways that are modified by moderate alcohol consumption to enhance immune response to vaccination. This increased susceptibility has been recapitulated in rodent models of chronic alcohol abuse. 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).
