Alcohol And Sickness: Is It Safe To Share?

Drinking alcohol while sick is generally considered unhealthy, as it can damage the immune system, slow down the healing process, and lead to negative side effects, especially when paired with medication. Furthermore, sharing drinks with someone who is sick can increase the risk of contracting the illness, as saliva transfer is likely to occur, which can spread germs, viruses, and bacteria. While the type of drink does not typically influence the risk of contracting an illness, crowded settings with close contact, such as bars, can increase the chances of exposure. Therefore, it is generally advised to avoid sharing drinks, especially with individuals who are sick, to minimize the risk of infection.

Alcohol damages the immune system, slowing down recovery

Alcohol has a detrimental impact on the immune system, making it easier for people to get sick and prolonging their recovery. Alcohol can slow down the body's ability to produce new white blood cells, which are crucial for fighting off infections. It also impairs cytokine signalling, which helps immune cells communicate and respond to new infections or vaccinations.

The gastrointestinal (GI) system is typically the first point of contact for alcohol, and it affects the structure and integrity of the GI tract by altering the gut microbiome. This disrupts communication between microorganisms and the intestinal immune system, damaging epithelial cells, T cells, and neutrophils in the GI system, and facilitating the leakage of microbes into the circulation. This can lead to inflammation and an overgrowth of harmful bacteria, triggering further immune dysregulation and systemic inflammation.

Even short-term or acute binge drinking can compromise the body's defences, making people more susceptible to infections and other health problems. Alcohol can also hinder the body's ability to recover from physical trauma, such as burns, hemorrhagic shock, and traumatic brain injuries. It can also affect cancer recovery by impairing immune function, which is crucial for successful chemotherapy treatment.

Additionally, alcohol reduces sleep quality, making it harder for the body to fight off infections and viruses. It can also cause the body to metabolize toxic chemicals and increase hormone levels, leading to a higher risk of developing certain cancers. Overall, alcohol consumption weakens the immune system and slows down recovery, making it unadvisable to share alcoholic drinks with a sick person as it could further compromise their immune system and delay their healing process.

Alcohol interacts with medication, hindering their function

The National Institute of Health (NIH) conducted a study of over 26,000 adults from the National Health and Nutrition Examination Study (NHANES) to determine their alcohol and prescription drug use. They found that over 70% of U.S. adults regularly drink alcohol, and roughly 42% of those who drink also use medications that can interact with alcohol. Utilizing a large database of over 1,300 medications, they found that 45% of these medications had the potential to interact with alcohol.

It is important to note that alcohol can interact with medication even if they are not taken at the same time. The effects of mixing alcohol with certain medications can include nausea and vomiting, headaches, drowsiness, fainting, loss of coordination, internal bleeding, heart problems, and difficulties in breathing. Older people are at particularly high risk of harmful alcohol-medication interactions due to age-related changes in how their bodies respond to both substances, as well as the likelihood of them taking multiple medications.

To avoid potential issues, it is recommended to review your medications with a pharmacist or healthcare provider to check for clinically significant drug-alcohol reactions. This is especially important for older adults, as educating them about the risks of combining medications with alcohol may help them avoid negative outcomes.

Alcohol dehydrates the body, causing headaches and body aches

It is not advisable to share drinks with a sick person, as this can expose you to harmful bacteria and viruses. The risk of infection increases when sharing drinks with children, as they tend to have more residual saliva, which can contain viral particles and mucus.

Alcohol is a diuretic, meaning it increases urine production and causes dehydration. Dehydration is a common cause of headaches and can also lead to body aches. When dehydrated, the brain and other body tissues shrink, and the brain pulls away from the skull, putting pressure on the surrounding nerves, which causes pain. Even mild dehydration can lead to a headache, and the pain can range from a mild dull ache to a sharp or stabbing sensation.

Drinking alcohol can lead to a hangover, which is associated with a range of unpleasant symptoms, including headaches, malaise, diarrhoea, loss of appetite, tiredness, nausea, and sensitivity to light and sound. The severity and duration of a hangover depend on various factors, including the amount of alcohol consumed, the drinker's nutritional status, ethnicity, gender, liver health, and medications.

To prevent dehydration and mitigate the effects of a hangover, it is essential to stay hydrated by drinking plenty of water before, during, and after alcohol consumption. Sports drinks or chicken soup can also help replenish electrolytes and provide additional nutrients. Avoiding caffeine and further alcohol consumption is crucial, as these substances can contribute to dehydration.

While sharing drinks, the risk of contracting an illness is always present, regardless of the drink's contents. Communal drinking and living in close quarters facilitate the spread of airborne illnesses and increase the likelihood of exposure to infectious individuals. Therefore, it is generally advisable to avoid sharing drinks, especially with sick individuals, to minimize the risk of contracting or transmitting an infection.

Alcohol increases the risk of infection through saliva transfer

Alcohol is a social lubricant and it is common for people to share drinks with friends and family. However, this practice can increase the risk of infection through saliva transfer, especially if one of the parties is sick.

Saliva plays a crucial role in maintaining oral health and protecting the upper digestive and respiratory tracts from microbial pathogens. It contains antimicrobial immune defence systems that eliminate pathogens and prevent the overgrowth of microorganisms. However, alcohol abuse can impair these protective functions of saliva. Alcohol abuse affects the structure and function of the oral cavity mucosa, salivary glands, and saliva, compromising oral and general health. Therefore, when an individual has been drinking alcohol, their saliva may not effectively protect them from infections.

When individuals share drinks, salivary transfer of germs, viruses, and bacteria is likely to occur. This can lead to the spread of various illnesses, such as strep throat, the common cold, mumps, meningitis, mononucleosis, and even COVID-19. The risk of infection is higher when sharing drinks with someone who is sick, as the viral load in their saliva may be higher during certain stages of their illness. Additionally, drinking from the same container can increase the risk of infection, as the concentration of alcohol in the drink is not sufficient to protect against infection.

The risk of acquiring an infection through saliva transfer also depends on the person carrying the infection. Factors such as the shedding of the virus or bacteria and the sufficiency of the inoculum to cause an infection play a role. Furthermore, the setting matters, as crowded places with poor ventilation increase the likelihood of coming into close contact with someone who is ill.

While it may be tempting to share a drink with a sick person, especially if they are a close contact, it is important to consider the potential risks associated with saliva transfer. To reduce the risk of infection, it is recommended to avoid sharing drinks, especially with individuals who are ill. Maintaining good oral hygiene practices and regularly cleaning shared surfaces can also help reduce the spread of infections.

Alcohol heightens the chances of bacterial and viral infections

Alcohol consumption is linked to a higher risk of bacterial and viral infections. Firstly, alcohol-based hand sanitizers can be effective at killing viruses and bacteria. However, this is not the case with alcoholic beverages. The concentration of alcohol in a drink is not high enough to protect you from infection.

Secondly, alcohol consumption can damage the digestive system, including the gut microflora. This can lead to an increase in inflammation, killing off good bacteria that aids in digestion and nutrient absorption. As the well-being of the digestive system is directly linked to immune response, changes in the digestive tract can impact the ability to fight off infections. Alcohol also damages cells in the intestines, which can lead to malnutrition and a weakened immune system.

Thirdly, alcohol may affect the lungs' immune system, making individuals more susceptible to respiratory infections such as pneumonia and COVID-19. This effect is worsened if the person is a smoker. Heavy drinking lowers the immune system and can make it harder for the body to fight off infections.

Finally, alcohol affects judgment, leading to a higher likelihood of engaging in risky behaviors and poor hygiene practices, which can increase the chances of infection. It is important to note that the risk of infection is heightened in crowded settings with limited ventilation, such as bars, where individuals are in close contact and may share drinks.
