The air passages of the lungs are lined with cells secreting mucus, which normally traps particles of dust. When the membranes get infected and inflamed, the secretion of mucus increases and the lining of the air passages is irritated. Coughing is the action by which excess mucus is driven out.

Symptoms of Cough

Person takes a deep breath in

A person who is going to cough first draws a deep breath in. This action causes his glottis to close and his muscles to contract, thus building up pressure in the chest. Then suddenly, the glottis opens, an explosive discharge of air sweeps through the air passages and carries with it the excess secretions or, in some cases, foreign matter, which has irritated the larynx, trachea, or bronchi.


Causes of Cough

Cough Symptoms, Causes, Remedy and Diet

Inflammation of larynx or pharynx

A cough may be caused by inflammation of the larynx or the pharynx. A cough can develop in the chest due to change in weather or seasonal changes.

Clogging of the bronchial tubes with waste matter

The real cause of this disorder, however, is clogging of the bronchial tubes with waste matter. This is due to wrong feeding habits. The reason for higher incidence of cough during winter than in other seasons is that an average person usually eats more of catarrh-forming foods such as white bread, meat, sugar, porridge, puddings, and pies during the colder months of the year. Being overclothed with heavy undergarments and other garments during this period also prevents proper aeration of the skin.
