The liver is essential for detoxifying the bloodstream, regulating metabolism, and producing proteins crucial for immune function and blood clotting. To understand how alcohol interacts with your immune system, it is helpful to think of the immune response as a multi-faceted process. When a pathogen invades the body, several steps must occur to neutralize it. Specialized immune cells (e.g., white blood cells such as macrophages, neutrophils, and lymphocytes) identify the pathogen and mount a coordinated response. This process relies on a complex communication network involving cytokines and other signaling molecules that help guide and regulate immune cells.
Factors That Affect How Alcohol Affects Your Immune System
The intestine contains microorganisms that help maintain a healthy immune system, reduce the risk of infection and help the gastrointestinal tract function normally. Alcohol intake kills this bacteria, hindering the body’s ability to clear pathogens. Without healthy gut bacteria, viruses and infections can worsen and develop into more severe complications. Alcohol also damages T cells, neutrophils, and epithelial cells, which disrupts the gut barrier’s function.

The effect of beer on the immune system may not be as significant as the effect of stronger alcoholic beverages, but it’s important to remember that beer and wine can cause adverse health effects and even suppress the body’s immune response in excessive amounts. The impact alcohol has on the body is mainly due to the way the body processes alcohol. Factors such as the amount of alcohol a person drinks, how often a person drinks, the type of alcohol they drink, and whether they are biologically male or female can increase or decrease how much it affects their immune system. Alcohol also causes the body to metabolize toxic chemicals and increase hormone levels. For example, an increase in estrogen can lead the body to develop breast cancer. When a person drinks alcohol, their body metabolizes it Halfway house into acetaldehyde, a chemical that can damage DNA and prevent the body from repairing it.
- The problem is that your HPA axis views alcohol as a stressful event and elevates your stress hormone levels when you drink (hi, cortisol).
- As a client, you will live on-site on 14-wooded acres with upscale accommodations as you attend treatment for substance use disorder.
- If you are in recovery from alcohol use disorder or seeking to protect your immune health, abstaining may be the best option.

The Chief Medical Officer’s guidelines state men and women should not regularly drink more than 14 units of alcohol per week to avoid alcohol-related health problems. Those at risk of ill-health due to underlying conditions such as diabetes or heart disease are advised to consume even less than this. Maintaining a healthy, moderate relationship with alcohol is important when considering ways to improve your health and wellbeing. During deep sleep, your immune system produces proteins called cytokines, which help fight infections and inflammation.
Since pneumonia is an infection inside the lung, a person can gradually cough it out. Empyema occurs outside of the lungs, so doctors must remove it via surgery or by draining it with a needle. Those who have any of the known risk factors for COVID-19, like heart disease or diabetes, should drink even less. For those who have a risk factor for COVID-19, like heart disease or diabetes, he recommends drinking even less. That said, evidence also shows that even smaller amounts of alcohol can affect the immune system. According to the Cleveland Clinic, once you take a sip of alcohol, your body prioritizes breaking down alcohol over several other bodily functions.
- A compromised liver due to alcohol-related damage may struggle to mount an effective immune response, elevating the risk of viral infections.
- 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.
- Read more to find out why heavy drinking and immune health just aren’t compatible.
Short-term Effects of Alcohol on the Immune System
Response to different stressors is mediated by several neural circuits that converge on the paraventricular nucleus (PVN) of the hypothalamus (Myers, McKlveen et al. 2014). The PVN regulates pituitary hormone production, including adrenocorticotropic hormone (ACTH), which binds to melanocortin type 2 receptors in the does alcohol lower immune system adrenal cortex to induce steroidogenesis in distinct layers (Dringenberg, Schwitalla et al. 2013). Primates have a threelayer adrenal cortex with cortisol being the primary glucocorticoid produced in the zona fasciculata (Nguyen and Conley 2008), which is released in response to stress (O’Connor, O’Halloran et al. 2000). Corticosterone is the main glucocorticoid involved in the regulation of stress responses in rodents (Smith and Vale 2006). As a result, a person becomes vulnerable to infections that invade their body. It contains numerous cells and proteins that recognize infections and fight them.
Essentially, it balances organisms that help with digestion and the absorption of valuable nutrients. 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. As things progress, an individual’s immune system response improves and becomes strong enough to attack and eliminate the bacteria or virus that is present. Consider that alcohol can be part of our social lives, influencing how we connect with friends (virtually or otherwise). If we drink once in a while, we get the benefits of an enjoyable connection.
We can’t stress enough the importance of moderation in consuming alcohol to maintain robust immunity. You don’t have to be a chronic alcoholic in order for your health and immunity to suffer. Microglia express PRRs, produce cytokines, and modulate neuroinflammatory reactions in brain injury and neurodegenerative diseases (Block, Zecca et al. 2007). Changes persisted at least 30 days after alcohol exposure suggestive of longlasting consequences of ethanol on microglia function (McClain, Morris et al. 2011).
