Home » Cough


Cough is a reflex action started by stimulation of sensory nerves in the lining of the respiratory passage. When a person coughs, there is a short intake of breath and the voice box closes momentarily. The abdominal and chest muscles used for breathing contract, which in turn increases the pressure needed to drive air out the lungs when the voice box re-opens. The resulting blast of air comes out at high speed, scrubbing and clearing the airway of dust, dirt or excessive secretions. The cough reflex is a vital part of the body’s defence mechanisms.
