Understanding the Mechanics of a Persistent Cough

Dry cough, also known as non-productive cough, is a common respiratory symptom that can be quite bothersome. Unlike a productive cough that brings up mucus or phlegm, a dry cough does not produce any sputum. It is often described as a persistent, irritating, and tickling sensation in the throat, which leads to repeated coughing without relief.Dry cough can be caused by various factors, including allergies, irritants, infections, and underlying medical conditions. It can be acute, lasting for a few weeks, or chronic, persisting for more than eight weeks.
