10 Causes of the Common Cough: Explained

9. A Viral Cough

Perhaps the most common cause of coughing, viral infections typically induce inflammation and coughing even after the underlying condition goes away. A backflow of mucus in the through usually causes this, so cough syrups usually provide relief. Hot fluids also work well against the inflammation, though you may need nasal sprays in severe cases. Check with your doctor if a cough doesn’t go away within a reasonable timeframe to ensure you don’t need extra medicine or that you don’t have another issue.
