Your body has many ways of defending you from the bugs that cause the common cold. One defence mechanism is the production of mucus, a sticky, slimy substance that entraps viruses and bacteria in its slippery layers.
The body may try to expel mucus from the respiratory tract by coughing. This is fine if the cough is moderate and productive, but not so great if the cough doesn’t result in the expulsion of catarrh, and continues unabated for ages. Lingering coughs can last for up to three months after a common cold, according to Professor Eccles, Director of the Common Cold Centre in Cardiff.
