Does Alcohol Cure a Cold or Make It Worse?

The common cold is a viral infection primarily affecting the nose and throat. Despite its prevalence, misconceptions about its treatment persist, including the belief that alcohol can serve as a remedy. This article examines the scientific evidence regarding alcohol consumption during a cold, exploring its effects on the body and outlining effective strategies for relief.

Alcohol and Colds: The Reality

Alcohol does not cure a common cold. Colds are caused by viruses, such as rhinoviruses, and alcohol possesses no antiviral properties capable of eliminating these pathogens. While some older studies suggest moderate alcohol intake might reduce the frequency of colds over time, this does not translate to treating an active infection. The Centers for Disease Control and Prevention (CDC) generally advises against consuming alcohol if one does not already drink.

The misconception that alcohol helps a cold may stem from temporary sensations like a warming feeling or a brief dulling of symptoms. For instance, the warmth from a hot toddy, with honey and lemon, can temporarily soothe a sore throat. However, these effects are fleeting and do not address the underlying viral infection. Alcohol is not a decongestant; in fact, small amounts can cause blood vessel widening, which might worsen nasal congestion.

How Alcohol Affects Your Body During Illness

Consuming alcohol while battling a cold can have several negative physiological impacts, potentially prolonging the illness or worsening symptoms. Alcohol acts as a diuretic, leading to increased fluid loss and dehydration. Dehydration can exacerbate cold symptoms such as a sore throat and congestion, making recovery more challenging.

Alcohol can also temporarily suppress the immune system, making it harder for the body to fight off the viral infection. It can reduce the production of white blood cells and impair their function, which are both crucial for combating invaders. Even moderate alcohol consumption can weaken immune responses for up to 24 hours, increasing susceptibility to infections and potentially delaying recovery.

Additionally, alcohol can disrupt sleep quality, preventing the body from reaching the deeper stages of sleep necessary for healing. Adequate rest is a fundamental component of recovery from any illness. There is also a risk of dangerous interactions between alcohol and common over-the-counter cold medications. Combining alcohol with antihistamines, decongestants, or pain relievers like acetaminophen can intensify side effects such as drowsiness, dizziness, and liver damage, or even lead to respiratory depression.

Proven Approaches for Cold Relief

Effective cold relief focuses on supporting the body’s natural healing processes and alleviating symptoms. Getting sufficient rest is important, allowing the body to conserve energy and fight the infection. Staying home from work or school during the initial days of symptoms also helps prevent spreading the virus to others.

Proper hydration is also important. Drinking plenty of fluids like water, clear broths, and herbal teas helps thin mucus, making it easier to expel, and prevents dehydration. Over-the-counter medications such as pain relievers can help manage symptoms like headaches and body aches, while decongestants can reduce nasal stuffiness. These medications treat symptoms but do not cure the viral infection itself.

Various comfort measures can provide additional relief. Using a cool-mist humidifier can add moisture to the air, soothing irritated nasal passages and throats. Gargling with salt water can temporarily ease a sore throat and help clear mucus. Honey can also be effective in soothing coughs for adults and children over one year old. Practicing good hygiene, such as frequent hand washing and covering coughs and sneezes, is also important in preventing virus spread.
