How Does Alcohol Consumption Affect the Immune System?

Stress is one of the things that plays a major role in your immune system. It can impact your blood pressure, cholesterol level, brain chemistry, blood sugar levels, and hormonal balance. It is also increasingly viewed as a cardiovascular risk factor. Studies have shown that short term stress can actually boost the immune system, but chronic stress, which we are all facing now, has a significant effect on the immune system, which can manifest an illness. There is currently no vaccine so we are counting on our immune system to do most of the work for us. 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.

  • The question is, how long does it take for your immune system to recover?
  • These are individuals drinking at heavy levels when they drink.
  • After drinking has fully stopped, it’s time to take steps towards your overall health that also increase the strength of your immune system.
  • So people can also call three, three, six, seven, zero COVID-19 if they would like to speak to someone, uh, over the telephone.
  • As a result, it was concluded that alcohol does leave the body vulnerable to infectious diseases.

Research indicates that alcohol disrupts nearly all cells of the immune system, and that includes decreasing the number of infection-fighting white blood cells. At The Raleigh House, we have over 10 years of experience helping people recover from alcoholism and achieve lasting recovery. Antibiotics are so important as alcohol has essentially put a stop to any chance of the lungs to naturally rid themselves of bacteria. The accidental inhalation of other fluids such as drinks or vomit can increase the severity of pneumonia infections to often life-threatening levels. Long-term impacts to the immune system happen alongside long-term alcohol abuse. In cases where an individual has been drinking heavily over a long period of time, they will find that they are sick more often than their peers even if they are otherwise in better shape. Alcohol abuse can have immense impacts on your immune system even if you haven’t been drinking for years on end.

Alcohol and The Immune System During COVID-19

And, um, uh, causing the body to be healthier and more physically able to respond and fight off difficult situations. So we have this, this, uh, I guess there’s kind of a couple of factors. If we’re home, we have, we have a higher level of stress cause everything else going on, but then we also have access, you know, potentially increased access.

“Higher percent alcohol in hard liquor may kill more bacteria in the gut.” “Alcohol also destroys the protective lining inside your respiratory tract that your immune system uses to prevent upper respiratory tract infections like the common cold,” Dasgupta says. Lung conditions linked to alcohol include pneumonia, tuberculosis and acute respiratory distress syndrome, according to the NIAAA.


Perhaps the most dangerous effect is that alcohol use may affect the white blood cells in the body, which are responsible for getting rid of killer white blood cells. Without this defense system, a person is at a heightened risk of developing more life-threatening diseases, such as cancer. Excessive drinking reduces the number and function of three important kinds of cells in your immune system–macrophages, T and C cells. Macrophages are the first line of defense against disease.

The monkeys classed as heavy drinkers showed diminished responses to the vaccine, compared with the monkeys that consumed sugar water. But the investigators were surprised to find that the monkeys deemed as moderate drinkers demonstrated an enhanced vaccine response. Begin with a free call to an addiction & behavioral health treatment advisor. The We Level Up treatment center network delivers recovery programs that vary by each does alcohol weaken your immune system treatment facility. Studies using postmortem human brains have found that immune factors are increased in the brains of people who had alcohol use disorder. These effects appear to be particularly attributed to altered immune function, which makes patients more vulnerable to subsequent challenges to the immune system, such as surgery or infection. As a result, these patients are more likely to die during the recovery period.

Percocet Addiction

Meth is one of the most addictive drugs and it also has potentially fatal side effects. Continue to read more to learn what affects how long does meth stay in urine and how the body breaks down meth. In addition to its direct effects on the immune system, alcohol can have an indirect impact on immunity through its actions in the stomach and intestines . The GI tract is one of the first parts of the body to come into contact with alcohol and, as a result, bears the brunt of alcohol’s harmful effects.

Learn how bupropion interacts with alcohol, whether it is safe, and the potential side effects. Consuming alcohol with lithium, a medication used to treat bipolar disorder, can have dangerous side effects. Messaoudi adds that the team plans to further investigate how immune system responses to vaccinations can be boosted using these findings.
