Do Drinks and Immunity Mix? The Truth About Alcohol and the Immune System

alcohol and the immune system

Let’s talk about something you may not have thought about before the effect of alcohol consumption on your immune system. In recent years, research has found that alcohol can have a negative impact on your immunity, especially if you’re over 40.

That’s why it’s important to understand the connection between drinking and immunity in order to maintain and improve overall health.

In this article, we’ll delve into how alcohol affects your body’s ability to defend itself against disease—and what you should do about it. Read on for an in-depth look at the world of alcohol and immune health!

Understanding Alcohol’s Impact on Your Immune System

Alcohol plays an important role in how your immune system functions. While moderate drinking can be enjoyable, it’s important to understand how consuming too much alcohol can weaken your body’s natural defence mechanisms and make it harder for them to protect you from illness.

Alcohol interferes with the body’s ability to prevent infections in several ways. First, excessive drinking can reduce the number of white blood cells that help fight infection.

It also decreases the production of cytokines, essential molecules your immune system uses to protect against infections.

Furthermore, alcohol decreases the absorption of Vitamin A and Zinc, which are important components of a healthy immune system.

To ensure that you don’t overdo it when drinking, limit yourself to no more than one drink per day for women and two drinks per day for men. But we strongly advise you not to do it every day or even several days in a row.

Keep in mind that some types of alcohol contain more ethanol than others – beer typically has less ethanol content than wine or liquor – which means you should pay attention to how many servings you’re drinking and adjust accordingly.

Alternatives to Alcohol if You’re Immunocompromised

Try as we might, we can’t escape the fact that alcohol does impact your immunity. But don’t despair – there are plenty of options to choose from if you want a drink but want to avoid the negative side effects.

For starters, a glass of wine isn’t your only option – also consider non-alcoholic beer, kombucha, and ginger beer. Look for drinks that contain lactic acid bacteria that help boost your gut health—the gateway to a better immune response.

Also, consider herbal and fruit teas, fresh juice made with tonic water or sparkling mineral water, sodas with fresh juices and herbs added, and freshly squeezed lemonade. All these drinks are great alternatives that won’t compromise your immune system too much.

And, of course, don’t forget to stay hydrated! The Institute of Medicine recommends 3 litres (13 cups) of total beverages for men each day and 2.2 litres (9 cups) for women daily. So make sure you stay on top of your water intake!

Liver Damage and Its Relation to Immune System Health

Consuming alcohol can, over time, damage your liver and disrupt your body’s natural ability to fight off infection and disease.

Liver damage from alcohol consumption can lead to a depressing outcome: a weakened immune system.

Circulating Immune Cells

Long-term drinking leads to suppressed numbers of the two main circulating immune cells in your body— white blood cells and B lymphocytes. This depletion can make you more susceptible to infection and disease, as your body has fewer defenders against invading microbes.

Regenerating Healthier Liver Tissue

The liver is designed to regenerate its healthier tissue, but with long-term alcohol consumption, the process can be disrupted. As the tissue isn’t being replaced correctly or at all, any infection or virus will have long-lasting detrimental effects on your health as there aren’t enough cells to fight off the viruses or bacteria.

Alcohol has lasting impacts on your body beyond reducing stress in the moment- it can weaken your immune system if you’re not careful with how much you drink and when.

Taking precautions like limiting yourself to no more than one drink per day (assuming you are of legal drinking age), alternating between water and alcohol, and eating healthy during those times will go a long way towards helping keep your immunity strong for years down the line.

Alcohol and Autoimmune Diseases

It’s important to remember that drinking alcohol can affect your immune system in various ways, so looking at the bigger picture is important when considering how your drinking habits may impact your health—especially if you have an autoimmune disease.

Alcohol can weaken the immune system in several ways, thereby making it more difficult for your body to fight off infections:

  • It reduces the number of white blood cells (WBCs) responsible for fighting infections and diseases.
  • It alters the function of WBCs, impairing their ability to recognise and combat bacteria and viruses.
  • It increases inflammation in the body, which can lead to autoimmune flare-ups.

When coupled with existing genetic factors related to autoimmunity, alcohol consumption can lead to flare-ups and a decline in overall health.

In some cases, it can even trigger an autoimmune disease if you’re genetically susceptible to it. So if you have an existing autoimmune condition or are genetically predisposed, it might be a good idea to stay away from alcohol altogether.

Tips for Moderating Alcohol Consumption

Enjoying a few drinks is one thing, but it turns out there are some tips you should know about when it comes to alcohol consumption and your immune system. Here’s what you need to consider:

Don’t Drink Every Day

Research suggests that the occasional glass of wine or beer is unlikely to impact your immune system negatively. However, drinking every single day—especially heavy drinking—is associated with changes in immunity, leaving you more vulnerable to infection.

Remember Serving Sizes

It’s easy to drink more than you intend, especially if alcohol isn’t something you drink frequently. Remember that a standard serving size of wine is five fluid ounces, and a standard beer bottle is 12 fluid ounces.

Taking note of proper servings can help ensure your alcohol intake remains in check and moderate.

Allow Time Off Between Drinks

Finally, if you’re going to have multiple servings in one night, give your body a break between them. There are gap times suggested for how long between drinks for alcohol-related health effects and reducing any ill feeling the next day.

Optimising Your Immunity Through Diet and Lifestyle Changes

Why not substitute for some non-alcoholic drinks? There have never been so many options!

So, what else can you do to make sure you’re protecting your body’s immune system? Well, the good news is that you can make some dietary and lifestyle changes to ensure that your body is best equipped to fight off sickness.


Your diet plays a major role in immunity. Eating healthy meals with lots of fresh fruits, vegetables, and leafy greens will provide essential vitamins and minerals for immune system health. Additionally, eating foods that are rich in prebiotics, probiotics, and antioxidants can help keep your gut healthy and boost your immunity.


Regular exercise helps to strengthen the immune system by increasing oxygen flow throughout the body, which increases white blood cell production. High-intensity workouts are more effective for strengthening immunity than low-intensity ones.

Stress Management

Stress weakens your immune system, so practising healthy stress management techniques such as deep breathing exercises or mindfulness meditation is important.

Also, practise good sleep hygiene by going to bed at the same time every night and getting enough sleep—no less than seven hours per night!


In summary, it’s clear that alcohol affects the immune system, but the extent of the damage varies depending on how much you drink and how frequently.

Frequent and heavy alcohol consumption can significantly disrupt your body’s ability to fight infections, leading to an increased risk of disease.

The good news is that you don’t have to abstain from alcohol entirely to maintain a healthy lifestyle. You can still enjoy alcohol in moderation, but it’s important to remember that even moderate intake of alcohol can have an unfavourable effect on the immune system.

You may also consider supporting a healthy immune system with food supplements, such as our own line of high-quality and clean food supplements, as well as following a balanced diet and exercising regularly. Doing so will help you maintain a healthy lifestyle and reduce your risk of getting sick.

Q: What is the effect of alcohol on the immune system?

A: Alcohol consumption, particularly excessive alcohol use, can weaken and impair the immune system, making the body more susceptible to infections and diseases. This effect is observed in both chronic alcohol use and short-term binge drinking.

Q: How does alcohol use affect the immune system in the short term?

A: Short-term effects of alcohol on the immune system include the reduced ability of the immune cells to function properly, an increase in inflammation, and suppressed innate immune system responses. These effects can make individuals more prone to infections and diminish the body’s ability to recover from illness or injury.

Q: How much alcohol is too much for the immune system?

A: The amount of alcohol that significantly impacts the immune system varies from person to person. However, excessive alcohol use, such as binge drinking or heavy drinking, is generally associated with negative effects on the immune system. It is important to limit alcohol consumption and follow guidelines for moderate intake to minimize potential damage to the immune system.

Q: What are the long-term effects of alcohol misuse on the immune system?

A: Chronic alcohol misuse can lead to liver disease, including hepatitis and fatty liver, which can further impair immune function. In addition, chronic alcohol use can result in a weakened innate immune system, decreased immune cell function, and increased susceptibility to infections and diseases.

Q: Can moderate alcohol consumption have any adverse effects on the immune system?

A: Moderate alcohol consumption is typically not associated with significant adverse effects on the immune system. However, it is important to note that individual responses to alcohol can vary, and excessive alcohol use can still impact the immune system even if consumed in moderation over time.

Q: How does alcohol affect liver disease and the immune system?

A: Alcohol consumption, especially excessive alcohol use, can cause liver disease such as hepatitis, fatty liver, and cirrhosis. Liver disease can weaken the immune system by impairing the liver’s ability to remove toxins and harmful substances from the body, resulting in increased inflammation and susceptibility to infections.

Q: How does excessive alcohol use increase the risk of infection?

A: Excessive alcohol consumption impairs the immune system, making individuals more susceptible to infections. Alcohol can suppress the innate immune system, reduce the function of immune cells, and increase inflammation, all of which contribute to a higher risk of infections and diseases.

Q: Can alcohol withdrawal affect the immune system?

A: Alcohol withdrawal can cause an increase in inflammation and stress on the body, which might temporarily impact the immune system. However, as the body recovers from alcohol withdrawal, the immune system may gradually improve and regain normal functioning.

Q: What is the point of contact for alcohol with the immune system?

A: The point of contact for alcohol with the immune system is primarily through the liver, where most of the metabolism and detoxification of alcohol occurs. The liver is also an essential organ for immune function, and alcohol-induced liver damage can directly impact the immune system.

Q: Can regulating alcohol consumption improve immune function?

A: Yes, regulating alcohol consumption and limiting excessive alcohol use can improve immune function. By maintaining moderate alcohol consumption and avoiding binge drinking or heavy alcohol use, individuals can minimize the negative effects on the immune system and promote overall health.
