A cough can be a real annoyance, but it is meant to do your body good. This rapid expulsion of air from your lungs is your body’s natural reaction to clear your throat of irritants, mucus, fluid, microbes, and foreign particles. The act may be voluntary or involuntary.
Oftentimes, a cough would go away on its own, even without any treatment. Other times, it is a symptom that signals the onset of another illness, such as the flu. Even though there is usually no need to worry, a cough that lasts longer than usual might be a cause for concern.
If you are wondering why your cough is taking so long to go away, here are 17 possible reasons to consider.
