Beer And Covid-19: What's The Verdict?

Drinking alcohol is not recommended when you have COVID-19. While there is no official guideline to prevent you from drinking, it is best to avoid it. Alcohol can increase your risk of catching COVID-19 and can make you more vulnerable to the virus by compromising your immune system. It can also cause dehydration, as alcohol increases urine production and reduces thirst, which is a big problem when you are suffering from COVID-19. In addition, alcohol can negatively impact your mental health, making you feel lost and alone, and impair your liver's ability to metabolize medications effectively. Therefore, it is best to avoid alcohol and opt for healthier alternatives such as water, coconut water, herbal teas, and citrus drinks, which can help boost your immune system and keep you hydrated.

Drinking alcohol can increase your risk of catching Covid-19

Research has shown that heavy and chronic alcohol use can negatively impact the immune system and increase the risk of acute respiratory distress syndrome following a Covid-19 infection. A study by German researchers found that chronic drinking increases the levels of the ACE2 enzyme in the lungs, which is the receptor that Covid-19 attaches to and uses to enter and infect cells. This may lead to a higher probability of the virus entering and infecting the lungs.

The German study also found that excessive alcohol consumption can increase the levels of the enzyme TMPRSS2, which primes the virus's spike proteins, potentially accelerating the rate at which Covid-19 can infiltrate the body's cells. In addition, alcohol consumption was found to decrease the levels of the protective enzyme Mas in the olfactory bulbs, which may result in a lower anti-inflammatory response and contribute to the loss of smell often associated with Covid-19.

Chronic alcohol use has also been linked to higher rates of Covid-19 infection and more severe infections. This may be due to the negative impact of alcohol on the immune system, as well as the creation of conditions in the body that facilitate infection. The WHO also noted that alcohol consumption is associated with a range of health disorders, including communicable and noncommunicable diseases and mental health disorders, which can further increase an individual's vulnerability to Covid-19.

While moderate drinking may not have the same level of impact on the immune system, excessive alcohol consumption, especially over a prolonged period, can increase the risk of catching Covid-19 and potentially lead to more severe outcomes. Therefore, it is important to drink in moderation and prioritize one's health, especially during a pandemic.

Alcohol negatively impacts your immune system

Secondly, alcohol impairs the function of immune cells such as macrophages and neutrophils. Macrophages are white blood cells that destroy foreign particles by ingesting them, while neutrophils are white blood cells that patrol the blood for new foreign antigens. By damaging these cells, alcohol reduces the body's ability to fight off infections.

Thirdly, alcohol promotes inflammation throughout the body. It destroys the "good bacteria" in the gut that normally keep inflammation at bay, allowing inflammatory molecules called cytokines to spread. This widespread inflammation can lead to autoimmune-like effects in the body, such as autoimmune diseases.

Additionally, alcohol can interfere with healthy sleep, which is known to protect against infection. Even a single occasion of drinking can negatively impact your immunity, and excessive drinking (defined as 14 or more drinks per week) can directly lower your immune system's defences.

Overall, alcohol consumption can weaken the body's natural defence against diseases, leaving heavy drinkers more susceptible to sickness and increasing the risk of contracting infectious diseases.

Alcohol can cause dehydration

Drinking alcohol can be a great way to celebrate, but it's important to be aware of its potential effects on your body, like dehydration.

Alcohol is a diuretic, which means it can cause your body to remove fluids more quickly than other liquids. This happens because alcohol suppresses the release of the antidiuretic hormone vasopressin, which controls how much water your kidneys reabsorb and retain. As a result, you may need to pee more, and you can become dehydrated if you don't drink enough water along with your alcoholic beverage. This is especially true if you're drinking on an empty stomach, as the alcohol will be absorbed into your bloodstream more quickly.

To make sure you stay hydrated while enjoying a drink, it's a good idea to have at least one glass of water for each serving of alcohol. It's also important to drink slowly and give your liver time to process the alcohol—about one hour per serving.

While moderate drinking is generally considered safe for most people, binge drinking or chronic heavy drinking can have serious negative health consequences. These include an increased risk of injury, high blood pressure, weakened immunity, gastrointestinal problems, cardiovascular complications, and certain types of cancer.

So, if you're celebrating and want to include alcohol, be sure to drink in moderation, stay hydrated, and listen to your body.

Alcohol can negatively impact your mental health

While drinking alcohol is generally considered acceptable in most parts of the world, excessive alcohol consumption can have detrimental effects on one's mental health. Alcohol use disorder (AUD) is a condition characterised by a problematic pattern of alcohol use that persists despite negative consequences. People with AUD may find themselves unable to cut down on drinking, and may experience cravings, increased tolerance, and withdrawal symptoms upon attempting to quit.

AUD often co-occurs with other mental health disorders, including anxiety, depression, trauma- and stress-related disorders, and sleep disorders. Alcohol can negatively impact mental health by altering the balance of neurotransmitters in the brain, which are essential for proper functioning. This can lead to worsening feelings of anxiety and depression, as well as cognitive issues such as memory loss and problems with learning.

Additionally, long-term alcohol misuse can cause permanent changes to the brain, including problems with understanding, remembering, and thinking logically. It can also lead to social problems such as homelessness, job loss, divorce, and domestic abuse, all of which can further contribute to poor mental health.

Excessive alcohol consumption can also increase the risk of developing Wernicke-Korsakoff Syndrome (WKS), also known as "wet brain". This condition can cause persistent mental confusion, eye movement disturbances, coordination issues, and long-term memory and learning problems.

It is important to note that the impact of alcohol on mental health is complex and varies from person to person. While moderate alcohol consumption may provide some social and emotional benefits, excessive drinking can have severe negative consequences on mental well-being.

Alcohol can hinder the effectiveness of medication

Secondly, alcohol can influence the absorption and metabolism of medication, leading to higher blood alcohol concentrations and other adverse effects. This is particularly true for medications with sedative effects, such as benzodiazepines, which are commonly prescribed for anxiety and sleep disorders. The combination of alcohol and sedatives can increase the risk of adverse events, including falls, driving accidents, and fatal overdoses.

Thirdly, alcohol can alter the pharmacological effects of medication, either increasing or decreasing its impact on the body. This can lead to dangerous side effects, such as nausea, vomiting, headaches, drowsiness, fainting, loss of coordination, internal bleeding, heart problems, and breathing difficulties.

Additionally, alcohol can interact with medication in both pharmacokinetic and pharmacodynamic ways. Pharmacokinetic interactions occur when alcohol interferes with the metabolism of the medication in the liver, often by competing for the same enzymes. Pharmacodynamic interactions occur when alcohol enhances the effects of the medication, particularly in the central nervous system.

It is important to note that even moderate alcohol consumption can lead to adverse health effects when combined with certain medications. The potential for harmful interactions is higher for older adults, as they are more likely to take medications that interact with alcohol and experience age-related changes in how their bodies process both alcohol and medication.

Therefore, it is essential to consult with a healthcare professional or pharmacist before consuming alcohol while taking any medication to avoid potentially dangerous consequences.
