The common cold appears to increase the number of "cough receptors" in the airways and makes them more sensitive, which triggers coughing, wheezing and breathlessness, a new study reports. People with asthma are especially vulnerable to this virus-induced coughing, said the researchers from Queen's University Belfast. The cough receptors also are known as transient receptor potential (TRP) receptors.
