Is it OK to drink coffee when sick? A comprehensive guide

5 min read

According to a study conducted by psychologists at the University of Bristol, coffee consumption reduced the 'malaise,' or general feeling of being unwell, associated with the common cold. So, is it OK to drink coffee when sick, and does it help or hurt your recovery?

Quick Summary

The decision to drink coffee while sick depends on your symptoms and illness severity. For mild colds, moderate coffee may offer an energy boost and temporary relief. However, for more severe illnesses involving dehydration, caffeine can worsen symptoms. It can also interfere with sleep and medications.

Key Points

  • Moderate is key: For mild illness, a moderate amount of coffee may be acceptable, especially for regular drinkers needing to avoid caffeine withdrawal headaches.

  • Risk of dehydration: Coffee is a diuretic and can contribute to dehydration, which is especially dangerous if you have a fever, vomiting, or diarrhea.

  • Prioritize sleep: The caffeine in coffee can disrupt your sleep cycle, hindering your body's ability to rest and recover effectively from illness.

  • Consider medication interactions: Caffeine can heighten the side effects of stimulants in cold medicine and interact with other prescriptions like antibiotics and thyroid medication.

  • Stomach sensitivity: Coffee's acidity can irritate an upset stomach, worsen nausea, or aggravate symptoms in individuals with acid reflux or ulcers.

  • Opt for alternatives: When in doubt, hydrating alternatives like herbal tea, water, and broth are safer choices that support your body's healing process.

Can Coffee Help You Feel Better When Sick?

For many people, coffee is a daily ritual that provides a welcome energy boost and increased alertness. When you're feeling sluggish and fatigued from a mild illness, a cup of coffee can be tempting. This temporary lift in energy and mood is one of the primary reasons people consider drinking coffee while sick.

Psychological and Symptomatic Benefits

  • Combats Malaise: Research has shown that both caffeinated and decaffeinated coffee can help reduce the groggy feeling, or malaise, that often accompanies a common cold. This suggests that the psychological comfort and routine of drinking coffee, in addition to the caffeine, can play a role in feeling better.
  • Headache Relief: The caffeine in coffee has vasoconstrictive properties, meaning it can narrow blood vessels. For headaches, particularly migraines, that are caused by dilated blood vessels, a small amount of caffeine may provide relief. It can also enhance the effect of pain relievers like acetaminophen and aspirin.
  • Antioxidant Support: Coffee is rich in antioxidants, specifically polyphenols, which can help fight inflammation and support the immune system. While it's not a cure, these compounds can offer a mild benefit to your body as it fights an infection.

The Potential Downsides of Drinking Coffee While Sick

Despite the perceived benefits, drinking coffee, especially in excess, can present several risks when you're under the weather. The body's needs are different during illness, and what is usually benign can become problematic.

Dehydration Risks

Caffeine is a mild diuretic, meaning it increases urination and can cause fluid loss. While moderate intake in regular coffee drinkers may not cause significant dehydration, a severe illness involving fever, vomiting, or diarrhea dramatically increases the risk. In these cases, prioritizing more hydrating fluids like water, broth, or electrolyte drinks is crucial for recovery. Dehydration can worsen symptoms and delay healing.

Impact on Sleep

Quality sleep is one of the most critical factors for recovering from any illness, as it allows your body to repair and rebuild. As a stimulant, caffeine can significantly disrupt your sleep cycle, especially if consumed later in the day. Trading a temporary boost in alertness for a night of poor sleep can be counterproductive to your recovery efforts. Experts recommend avoiding caffeine at least six to eight hours before bedtime to ensure proper rest.

Stomach Irritation

For those with gastrointestinal symptoms, coffee's acidic nature can aggravate an already upset stomach, causing nausea, indigestion, or acid reflux. People with stomach ulcers are particularly vulnerable, with some studies showing coffee can increase abdominal pain. If stomach issues are a primary symptom, avoiding coffee and opting for a gentler, low-acid beverage like herbal tea is advisable.

Medication Interactions

It is vital to be aware of potential interactions between caffeine and common medications used for cold and flu symptoms.

  • Stimulants: Many over-the-counter cold and flu remedies, including decongestants like pseudoephedrine, are stimulants. Combining them with coffee can heighten side effects such as jitters, anxiety, increased heart rate, and restlessness.
  • Antibiotics: Some antibiotics can interact with caffeine, altering the way the body processes the medication and potentially affecting its efficacy.
  • Other Drugs: Caffeine can also interfere with the absorption of thyroid medication (levothyroxine) and increase the effects of some antipsychotics and antidepressants. Always consult a healthcare professional about potential interactions.

When to Consider Drinking Coffee and When to Avoid It

Deciding whether to have that cup of coffee involves weighing your symptoms and health needs. There is no one-size-fits-all answer, so listening to your body is essential.

Mild Cold or Illness

For a minor cold that leaves you feeling a bit groggy but otherwise functional, a cup of coffee may be fine, especially if you are a regular drinker. The risk of dehydration is lower in moderate amounts, and avoiding the dreaded caffeine withdrawal headache can make you feel better. If you choose this route, drink plenty of water alongside your coffee to stay hydrated.

Severe Illness or Digestive Issues

If you have a fever, vomiting, or diarrhea, it's best to steer clear of coffee. The dehydrating effect and potential for stomach irritation are significantly higher. The same applies if you are experiencing severe nausea or acid reflux. In these cases, focus on clear liquids, broths, and electrolyte drinks to replenish lost fluids and support your recovery.

On Medication

If you are taking any medication for your illness, particularly cold and flu remedies with stimulants or certain antibiotics, it's wise to avoid caffeinated coffee. The risk of enhanced side effects and medication interference is not worth the temporary energy boost. Switching to decaf or herbal tea is a safer option until you've completed your medication course.

Conclusion

So, is it OK to drink coffee when sick? The answer is that it depends. For mild, non-gastrointestinal illnesses, moderate coffee consumption is likely safe and may even offer a temporary pick-me-up, especially for habitual drinkers trying to avoid withdrawal symptoms. However, it comes with risks of dehydration, sleep disruption, and medication interactions. If your illness is severe, involves stomach issues, or requires medication that can interact with caffeine, it is far safer and more beneficial to your recovery to choose hydrating, non-acidic alternatives like herbal tea or broth. Ultimately, listen to your body and prioritize rest and hydration to get back on your feet as quickly as possible.
