Beer And The Flu: A Safe Mix?

Drinking alcohol when you're sick is generally not recommended, and this includes drinking beer when you have the flu. Alcohol can weaken your immune system, disrupt your sleep, and cause dehydration, all of which can slow down your recovery. Alcohol can also negatively interact with certain medications, including some that are used to treat flu symptoms, such as acetaminophen, antihistamines, and ibuprofen. While there's a common misconception that alcohol kills viruses and bacteria, your blood alcohol content would have to be over 60% for that to be true—a lethal amount.

Beer can overwork your immune system

When you're feeling under the weather, your immune system is already working overtime to help your body heal. As a toxin, alcohol is prioritised by your body for metabolisation over all other substances. This means that your system has to fight off both the sickness and the alcohol, which can result in a slower recovery.

Dr. Kathy Gruver, a nutrition and stress specialist, warns that alcohol can weaken an already overloaded immune system. Your body can only metabolise a small amount of alcohol per hour, so consuming more than this will slow down your recovery as your body has to fight off the alcohol as well as the illness.

Dr. Robert Segal, Co-Founder of LabFinder, agrees that alcohol should be avoided when you're sick. He states that "your immune system is already weakened when you are sick. Adding alcohol to that equation can only prolong the process of getting better."

Alcohol's effect on the immune system is just one reason to avoid drinking while sick. It can also interrupt your sleep, which is necessary for recovery. While a small amount of alcohol can help you fall asleep faster, consuming more than one standard drink before bed will disrupt your deep sleep phase. This will leave you feeling groggy in the morning and can make your cold or flu symptoms worse.

In addition, alcohol can increase the rate of dehydration. As a diuretic, alcohol increases the passing of urine, causing the body to lose fluids and become dehydrated. Illness already increases the risk of dehydration, so drinking alcohol while sick can exacerbate this problem.

Alcohol negatively interacts with medication

Drinking alcohol while taking medication for the flu is not recommended, as it can negatively impact your recovery and cause serious health issues. Here are several reasons why alcohol negatively interacts with medication:

Immune System Impairment

Alcohol can weaken your immune system, which is already compromised when you are sick. This makes it harder for your body to fight off the flu infection and may prolong your recovery.

Sleep Interruption

While a small amount of alcohol may help you fall asleep faster, excessive consumption can disrupt your sleep. Specifically, it can interfere with REM sleep, the most restorative type of sleep, leaving you feeling more tired the next day.

Dehydration

Alcohol is a diuretic, which means it increases fluid loss through urination. When you have the flu, staying hydrated is crucial for recovery. Alcohol can worsen dehydration, making your congestion worse and prolonging your illness.

Interaction with Medication

Alcohol can have dangerous interactions with certain over-the-counter and prescription medications for the flu. For example, combining alcohol with acetaminophen (Tylenol) can lead to severe liver damage. Antihistamines, such as diphenhydramine (Benadryl), when mixed with alcohol, can cause excessive drowsiness, dizziness, and impaired coordination, increasing the risk of accidents. Cough suppressants containing dextromethorphan (DXM) should also not be mixed with alcohol as it can lead to respiratory depression and other serious side effects.

In summary, drinking alcohol while taking medication for the flu can negatively impact your recovery and cause adverse health effects. It is best to avoid alcohol until you have finished your treatment and are feeling back to normal.

Alcohol can cause dehydration

Drinking alcohol can lead to dehydration, particularly when consumed in large quantities. Dehydration occurs when the body does not have enough fluids to function effectively. Alcohol acts as a diuretic, causing the body to remove fluids more rapidly through the renal system, which includes the kidneys, ureters, and bladder. This can result in excessive urination, leading to a loss of vital fluids and electrolytes.

The risk of dehydration is higher when drinking alcohol on an empty stomach. In the absence of food, alcohol is absorbed directly into the bloodstream through the stomach lining and small intestine. This process can be slowed down by consuming water or food along with alcohol. Therefore, it is recommended to drink alcohol with food or to have at least one glass of water for each serving of alcohol.

Additionally, alcohol can suppress appetite, reducing the likelihood of eating while drinking. This can further contribute to dehydration as the body absorbs alcohol more quickly. It is important to be mindful of this and ensure adequate fluid intake when consuming alcohol.

Dehydration can have severe consequences, and in extreme cases, it can be life-threatening. Therefore, it is crucial to prioritize hydration, especially when drinking alcohol. This is particularly important for older adults and individuals with chronic conditions, who are at a higher risk of dehydration.

While the belief that alcohol causes dehydration has been questioned by some, with research suggesting that the additional urine output due to alcohol consumption may not be as significant as commonly believed, it is still important to stay hydrated while drinking alcohol. This is because alcohol can have other negative effects on the body, such as disrupting the balance of the microbiome, causing gastrointestinal distress, and affecting sleep quality.

To summarize, while drinking alcohol, it is important to be mindful of its potential dehydrating effects and take steps to stay hydrated. This includes drinking in moderation, drinking slowly, and ensuring adequate water intake. By doing so, individuals can reduce the risk of dehydration and its associated health risks.

Alcohol can negatively impact sleep

During a typical sleep cycle, your body transitions through three stages of non-rapid eye movement (NREM) sleep before ending with rapid eye movement (REM) sleep. Each stage serves a different function and is necessary for sleep to feel refreshing and for vital processes like learning and memory consolidation to occur. However, consuming alcohol before bed can lead to more deep sleep and less REM sleep in the first half of the night. This can result in fragmented and low-quality sleep later in the night, leaving you feeling tired the next day.

The negative impact of alcohol on sleep can be both acute and chronic. Acute effects include alterations in sleep architecture, such as more deep sleep and less REM sleep initially, followed by disrupted sleep later in the night. Chronic effects can include the development of sleep disorders like insomnia and changes in circadian rhythms, which regulate your sleep-wake cycle.

Additionally, alcohol can worsen pre-existing sleep disorders such as snoring and sleep apnea. It can also interfere with the treatment of these disorders, as alcohol and many sleep medications do not mix well.

To minimize the negative impact of alcohol on your sleep, experts recommend avoiding alcohol at least three hours before bed. If you are already dealing with sleep issues or taking sleep medication, you may need to avoid alcohol for even longer or abstain altogether.

Alcohol can cause internal bleeding

Drinking alcohol when you have the flu is generally not recommended. Alcohol can weaken your immune system, disrupt your sleep, and cause dehydration, all of which can slow down your recovery. Additionally, alcohol can interfere with the effectiveness of certain medications, including antibiotics, and can cause internal bleeding.

Alcohol abuse has been linked to an increased risk of internal bleeding, which can have serious and potentially life-threatening consequences. Alcohol can irritate and damage the linings of the esophagus, stomach, and intestines, making them more susceptible to bleeding. This damage can lead to conditions such as heartburn and alcoholic gastritis, which is characterised by ongoing bleeding from the stomach lining.

The toxins in alcohol can also affect the liver, causing a condition known as cirrhosis. Cirrhosis is a serious condition in which scar tissue forms in the liver, leading to fluid buildup in the abdomen and veins, and ultimately causing bleeding in the esophagus. Alcoholic ketoacidosis, resulting from a buildup of ketone acids in the blood, can also lead to internal bleeding as the high levels of ketone acids tear up the gastrointestinal tract.

Internal bleeding from alcohol abuse can cause a range of signs and symptoms, including:

• Coughing up blood
• Vomiting blood
• Blood in the stools or black, tarry stools
• Stroke-like symptoms
• Chest or abdominal pain
• Pale, cool, or clammy skin
• Symptoms of shock, such as hypertension or hypotension
• Loss of consciousness, excessive sweating, confusion, vision loss, speech difficulties, facial drooping, or severe pain or weakness on one side of the body

If you suspect internal bleeding, it is important to seek medical attention promptly. The signs of internal bleeding may not always be obvious, and delaying treatment can lead to serious health complications or even death.
