Introduction
Coffee has become an almost indispensable part of life for many people around the world. It is one of the most widely consumed beverages and is known to have numerous health benefits. However, there is much confusion among people about whether drinking coffee is safe for those with a cough or a cold. This article provides an insight into the research surrounding this topic, giving a comprehensive overview of if it is safe to drink coffee when you have a cough.
The Case for Drinking Coffee with a Cough
Proponents of drinking coffee with a cough argue that caffeine may help relieve symptoms of a dry cough. Caffeine is known to stimulate the brain, resulting in improved clarity, focus and alertness. Furthermore, caffeine is often found in cough medicines, so some argue it is safe to drink coffee while you have a cough as it has similar effects.
The Case Against Drinking Coffee with a Cough
However, there are also opponents of this claim, arguing that coffee consumption should be avoided when you have a cough. Caffeine is known to have a dehydrating effect, making it more difficult for the body to produce the saliva and mucus needed to get rid of a cough. Moreover, coffee may worsen symptoms, leading to further irritation of the throat and making it harder to breathe.
Scientific Evidence
Studies conducted on the effects of coffee consumption on coughing have returned conflicting results. While some studies have found that drinking coffee can help relieve symptoms of a dry cough, others have found that drinking coffee may not be beneficial for those with a cough. A recent study conducted in 2017 found that both caffeinated and decaffeinated coffee increased cough reflex sensitivity in participants, suggesting that both forms of coffee should be avoided when you have a cough.
Expert Opinion
Experts advise caution when it comes to drinking coffee with a cough. It is recommended to speak to a doctor before drinking coffee when you have a cough, as they will be able to provide tailored advice. Generally, experts agree that those with a cough should stick to warm drinks like herbal teas, or use an over-the-counter remedy to relieve their symptoms.
Is Coffee a Diuretic?
There is some debate regarding whether coffee is a diuretic or not. A diuretic is any substance that causes an increase in urine output, which can lead to dehydration. Caffeine has long been thought to have diuretic properties, but recent studies suggest it may only increase urine output when taken in high quantities. Similarly, decaffeinated coffee does not seem to have any observable diuretic effects.
Caffeine and Coughing: What is the Link?
The evidence investigating the potential link between caffeine and coughing is inconclusive. While some studies have found that caffeine may help relieve symptoms of a dry cough, others have suggested that it may make coughing worse in those with a cold. As such, it is important to understand the individual circumstances before making a decision on whether or not to drink coffee with a cough.
Role of Sugar in Cough Treatment
Sugar is often added to drinks to make them more palatable and it is one of the most common ingredients in many cough medicines. However, adding sugar to drinks may exacerbate coughing symptoms and make it harder to get rid of a cough. Therefore, it is sensible to limit the amount of sugar consumed when treating a cough, including when drinking coffee.
Considerations for Those Who Are Pregnant
Those who are pregnant should think carefully before drinking coffee with a cough. During pregnancy, caffeine can cross the placental barrier, putting strain on the baby’s cardiovascular system. Furthermore, the dehydrating effects of caffeine can increase the risk of preterm birth and low birth weight. As such, it is suggested that those who are pregnant stick to non-caffeinated beverages when they have a cough.
Conclusion
In conclusion, the evidence surrounding whether coffee is safe to drink when you have a cough is inconclusive. Studies suggest that it may offer some benefits to a dry cough, but it is likely to aggravate symptoms if you have a cold. Furthermore, it should be avoided by those who are pregnant. Therefore, it is important to understand your own personal circumstances and to speak to a doctor before drinking coffee when you have a cough.
