Alcohol interferes with the production and function of white blood cells, making it more difficult for our body to fight off viruses. when you use/abuse alcohol your resistance to colds increases. In fact, research has shown that even moderate alcohol intake can impair the immune response, increasing our susceptibility to infections. To reduce your risk of colds and flu, it is advisable to limit your alcohol intake. The Centers for Disease Control and Prevention (CDC) recommends that men should not exceed two standard drinks per day, while women should limit themselves to one drink per day. It’s also vital to stay well-hydrated and maintain a healthy lifestyle, including getting enough sleep, eating a balanced diet, and engaging in regular physical activity.

Can drinking alcohol help fight off a cold?

  • It may temporarily alleviate symptoms such as congestion or sore throat, but it does not treat the underlying cause of the cold.
  • Studies have identified ethanol-mediated changes in both miRNA abundance (Miranda et al. 2010; Pietrzykowski 2010) and epigenetic modifications within PBMCs (Biermann et al. 2009; Bleich and Hillemacher 2009; Bonsch et al. 2006).
  • Interestingly, abstinence for 30 days was sufficient to restore lymphocyte numbers back to control levels (Tonnesen et al. 1990).
  • First, it’s important to understand that our immune system is responsible for protecting our body from harmful bacteria and viruses.

That said, excessive alcohol consumption is highly damaging to human health and increases the risk of infection. It’s important to note that even moderate alcohol consumption can have an impact on your immune system. While the occasional drink may not have significant effects, regularly consuming alcohol in excess can gradually wear down your immune system’s ability to function optimally. Excessive alcohol consumption can have a negative impact on our immune system, making us more susceptible to colds and flu. Let’s take a closer look at how alcohol affects our immune system and what you can do to protect yourself this season.

Effects on T-Cell Numbers, Phenotype, and Activation

Similarly, chronic consumption of 18 percent ethanol in water for 31 weeks resulted in impaired antigen-specific CD8 T-cell responses following inoculation with Listeria monocytogenes (Gurung et al. 2009). The alcohol-related decrease in peripheral B cells primarily seems to be mediated by a decrease in the frequency of the B-2 B cells. The number of B-1a cells also seems to decline, but this decrease is accompanied by a relative increase in the percentage of B-1b cells (Cook et al. 1996). The loss of B-2 cells may explain why alcoholics often cannot respond adequately to new antigens. The relative increase in B-1b cells also may lead to autoantibody production, especially of the IgM and IgA classes (which is discussed below).

The Truth About Alcohol and Immunity

By limiting your alcohol intake, staying hydrated, and supporting your immune system with a healthy lifestyle, you can reduce your risk of falling ill this season. It’s no secret that excessive alcohol consumption can have detrimental effects on our overall health. While many people are aware of the negative impact alcohol can have on the liver, heart, and brain, few may realize that it can also weaken our body’s ability to fight off viruses, including the common cold and flu. In summary, these studies suggest that chronic alcohol abuse in humans and animal models results in Sober living house lymphopenia, increased T-cell differentiation and activation, and reduced migration (see figure 1).

These changes in turn compromise the organism’s ability to respond to pathogens and contribute to increased susceptibility to infections. Sleep is crucial for maintaining a healthy immune system and has been shown to enhance our body’s ability to fight off infections. When we don’t get enough quality sleep, our immune function weakens, leaving us more vulnerable to viruses. But excessive alcohol intake can have negative effects on our immune system, making us more prone to catching colds and flu.

  • Your immune system is responsible for protecting your body from harmful pathogens, including the viruses that cause colds and flu.
  • Naïve human T cells produce low levels of VDR, but expression is increased to moderate levels in activated T cells (Irvin et al. 2000).
  • These clinical observations were confirmed with cultured cells as well as in rodent studies.

Alcohol can irritate the lining of the respiratory https://ecosoberhouse.com/ tract, leading to inflammation and making it easier for viruses to enter the body. Additionally, alcohol can also impair the cilia, little hair-like structures in our respiratory tract that help to sweep mucus and debris out of our lungs. When the cilia are compromised, our body’s natural defense mechanism against viruses becomes less effective. To understand how alcohol affects our immune system, we need to first understand the role of the immune system in defending our bodies against infections.

Impact of AUD on Lymphocyte Development

Remember, prevention is key when it comes to protecting your immune system and overall well-being. Yes, excessive alcohol consumption can suppress the immune system, making us more vulnerable to infections like colds and flu. Alcohol may make us feel drowsy initially, but it actually interferes with the quality of our sleep. It reduces the amount of time that we spend in deep, restorative sleep, which is essential for our body to repair and rejuvenate. When we don’t get enough quality sleep, our immune system becomes weaker, making us more susceptible to catching colds and flu. Excessive alcohol consumption can weaken your immune system, leaving you more susceptible to various illnesses, including colds and the flu.

Responses to Vaccination

While we often hear about measures such as getting enough sleep, eating a healthy diet, and washing our hands regularly, one factor that is often overlooked is the consumption of alcohol. Moderate alcohol consumption is generally considered safe for the immune system, but excessive or chronic alcohol use can have detrimental effects. Moreover, alcohol impairs the function of our respiratory system, which is particularly concerning when it comes to battling respiratory viruses like the cold and flu.

Can consuming alcohol prevent colds?

Because alcoholics are at increased risk for hepatitis B (HepB) infections, immunization with a HepB vaccine is recommended. Another study (Rosman et al. 1997) demonstrated that the impaired antibody response in alcoholic patients (i.e., with consumption levels of 230 ± 16 g/day ethanol for 26.4 ± 1.8 years) can be improved by doubling the dose of HepB vaccine from 10 μg to 20 μg at 0, 1, and 6 months. Thus, mice that were chronically fed ethanol generated a weaker antibody response following vaccination with HCV compared with control mice (Encke and Wands 2000). Abstinence partially restored antibody responses against hepatitis antigens in a mouse model (Encke and Wands 2000). Alcohol-related alterations of immune surveillance also have been implicated in the development of cancer (Poschl and Seitz 2004).

Some older research suggests that moderate alcohol consumption may reduce the frequency of colds. However, the CDC recommends that people avoid drinking alcohol if they do not already do so. Moderate alcohol consumption may have limited effects on the immune system, but excessive or chronic alcohol use can weaken immune function. Furthermore, alcohol consumption dehydrates our bodies, which affects the ability of our mucous membranes to trap and eliminate viruses. This diminishes our body’s natural defense mechanisms, leaving us more susceptible to colds and other respiratory infections. T-cell activation was assessed by measuring the expression of human leukocyte antigen (HLA)-DR on the patient’s CD8 cells.

Alcohol impairs the function of immune cells, decreases the production of antibodies, and disrupts the body’s ability to fight off infections. Some studies suggest that moderate alcohol consumption, particularly red wine, may have certain heart-healthy benefits. However, the negative impact on the immune system outweighs these potential advantages. As described earlier for adult humans, alcohol can lead to increases in Ig levels during development, even if the numbers of mature B cells decrease. Thus, maternal alcohol consumption during pregnancy (12 mg/week for most of the pregnancy) increased IgE levels in the umbilical cord blood of the infants (Bjerke et al. 1994).
