Moderate alcohol consumption ‘boosts immune system’

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. Zhang H, Meadows GG. Chronic alcohol consumption in mice increases the proportion of peripheral memory T cells by homeostatic proliferation. Romeo J, Warnberg J, Diaz LE, Gonzalez-Gross M, Marcos A. Effects of moderate beer consumption on first-line immunity of healthy adults.

When combined with a suppressed immune system, this can be the perfect storm for a bad case of pneumonia. Mild chest pain after coughing or deep breathing.If your chest feels sore when you inhale deeply, this could be a sign of pneumonia. A viral infection may also cause difficulty in breathing due to congestion in your lungs, but this can also cause wheezing. For those already seeking support or who may need it, the advice is very different.

Specific Health Problems Linked to Low Immunity from Alcohol Consumption

Much progress has been made in elucidating the relationship between does alcohol weaken your immune system consumption and immune function and how this interaction affects human health. Continued advances in this field face several challenges, however.

How much alcohol does it take to weaken your immune system?

“Research has shown that high doses of alcohol (around 14 drinks per week or more than five to six drinks at a time) does directly suppress the immune system, and that alcohol abuse is associated with increased risk of infectious diseases,” Mroszczyk-McDonald said.

Alcohol, especially when used in excess, also weakens the lining of the stomach, allowing dangerous microorganisms to enter the flesh. Of course, these aren’t the only signs that someone is suffering from analcohol use disorder. Sometimes there are finer, more subtle signs that someone is suffering from AUD, like how they continuously monitor the amount of liquor being poured into everyone’s glasses at the party. Unfortunately, to many people, alcohol isn’t a breath of fresh air. Instead, even for moderate drinkers, alcohol is slow physical destruction. This condition occurs when bacteria enter the chest cavity’s pleural space, typically due to pneumonia or a post-surgery infection. A weakened immune system increases an individual’s chances of developing empyema.

Long-Term Consequences Of Alcohol Abuse On The Body

The spike in alcohol sales has alarmed health experts and officials around the world, who are concerned that increased drinking could make people even more vulnerable to the respiratory disease. Alcohol consumption has also been shown to alter immunoglobulin levels. 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. Although the innate immune response is immediate, it is not specific to any given pathogen. Some of the most notable contributors to the innate immune response include natural killer cells, neutrophils, monocytes, macrophages, and dendritic cells .

In fact, research shows that acute binge drinking also affects the immune system. There is evidence in a number of physiological systems that binge alcohol intake complicates recovery from physical trauma . Molina and colleagues review research showing that alcohol impairs recovery from three types of physical trauma—burn, hemorrhagic shock, and traumatic brain injury—by affecting immune homeostasis. Their article also highlights how the combined effect of alcohol and injury causes greater disruption to immune function than either challenge alone.

Cagetti E, Pinna G, Guidotti A, Baicy K, Olsen RW. Chronic intermittent ethanol administration in rats decreases levels of neurosteroids in hippocampus, accompanied by altered behavioral responses to neurosteroids and memory function. Excessive drinking can affect your nervous system, causing numbness and pain in your hands and feet, disordered thinking, dementia, and short-term memory loss.


Alcohol does not directly cause UTIs, but it can increase a person’s risk of developing a UTI and worsen the symptoms of an existing UTI. When alcohol hinders the body’s immune system, it also hinders its ability to fight UTIs because it allows bacteria to travel throughout the body faster. As soon as you drink a sip of alcohol, your body begins to prioritize breaking down alcohol. This means that its functioning shifts to focus on breaking down the alcohol and takes its energy from other critical functions such as fighting diseases. While your body is metabolizing alcohol, it has a lower ability to fight off infections and viruses, making you more vulnerable to developing a cold or more serious condition. Alcohol abusecan suppress your immune system, making you more vulnerable to infections caused by bacteria and viruses which might raise your risk of a bacterial infection such asurinary tract infections .
