However, at the two- and five-hour marks, immune system activity had dissipated to levels below those typically seen with sobriety, with a notable drop in both monocytes and natural killer cells. Also, a bump was seen in another type of cytokine protein that signals a drop in immune activity.

To this end, heavy drinkers have been shown to exhibit an increase in both IgA and IgM levels when compared to both moderate and light male drinkers. Within the GI tract, alcohol exposure can also alter the number and abundance of microorganisms present within the microbiome, all of which play an important role in normal GI function.

Alcohol distracts the body from other functions

With regard to alcohol lowers immune system-mediated immunity, a reduction in CD3+, CD4+, and CD8+ cell numbers has been found after chronic alcohol administration in male ratsReference Boyadjieva, Dokur, Advis, Meadows and Sarkar 19. In contrast, in humans an increase in absolute values of the CD3+ lymphocytes has been recently found after 30 days of moderate beer consumptionReference Romeo, Warnberg, Nova, Díaz, González-Gross and Marcos 11.

Alcohol has a variety of effects on the immune system and can make people more susceptible to infections and other health conditions, including COVID-19. 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.

Continued advances in this field face several challenges, however. The regulation of immune function is exceedingly complex.

What weakens the immune system?

Your immune system can also be weakened by smoking, alcohol, and poor nutrition. AIDS. HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system. People with HIV/AIDS become seriously ill with infections that most people can fight off.

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. This is not the first study to show the potential benefits of moderate alcohol consumption. Earlier this year, Medical News Today reported on a study suggesting that consuming a glass of wine a day may reduce the risk of depression, while other research suggests a compound found in red wine could help treat cancer. Particularly with our vulnerability with the Cova at 19.

How Does Heavy Drinking Lower Your Immune System? alters the makeup of your gut microbiome — home to trillions of microorganisms performing several crucial roles for your health — and affects those microorganisms’ ability to support your immune system. It seems that drinking alcohol may also damage the immune cells that line the intestines and serve as the first line of defense against bacteria and viruses. In addition to pneumonia, alcohol consumption has been linked to pulmonary diseases, including tuberculosis, respiratory syncytial virus, and ARDS. Alcohol disrupts ciliary function in the upper airways, impairs the function of immune cells (i.e., alveolar macrophages and neutrophils), and weakens the barrier function of the epithelia in the lower airways . Often, the alcohol-provoked lung damage goes undetected until a second insult, such as a respiratory infection, leads to more severe lung diseases than those seen in nondrinkers. Similar to how we prepare our master’s students to become addiction specialists and our addiction research and clinical health program here on the campus.

Should I drink alcohol while sick?

Prolongs sickness

Alcohol's effect on your immune system is one reason to avoid drinking while sick. Drinking alcohol can weaken your body's ability to fight off infection. A weakened immune system can make your body more susceptible to getting sick and slow down recovery.

Drinking at this time may actually lower immunity and make a person more susceptible to the disease. When the balance is disrupted, it becomes difficult for the good bacteria in the gut to overcome the bad bacteria. Also, excess alcohol weakens the stomach’s lining, which allows dangerous microorganisms to enter other parts of the body. Drinking alcohol is a major factor in the disruption of the digestive system. As a result, a person experiences gastrointestinal challenges that lower immunity. Indeed, the immune system requires time to establish a response to a foreign invader. Therefore, when a person gets sick, the initial symptoms are bothersome and noticeable.
