Coughing is a vital reflex that helps protect our airways by clearing irritants and secretions. It’s often triggered when particles like dust, smoke, or pathogens such as viruses and bacteria irritate sensory nerves in the airways. These nerves send signals to the brain's cough center, which coordinates a deep inhalation, vocal cord closure, and a forceful exhalation to expel air and clear the airway.

Coughing is also a common symptom of medical conditions. Respiratory infections like colds, flu, and bronchitis cause airway inflammation and mucus buildup, leading to coughing as the body tries to clear the airways. Chronic conditions such as asthma, COPD, and GERD also contribute to persistent coughing. In asthma and COPD, inflamed and narrowed airways make breathing difficult, while GERD causes stomach acid to irritate the throat, triggering cough.

Environmental factors like allergens, smoke, and pollution also play a role. Allergens such as pollen or pet dander can provoke allergic reactions that result in coughing, while smoking and secondhand smoke damage the cilia in the respiratory tract, leading to chronic bronchitis and a persistent cough. Additionally, coughing serves as a critical defense against aspiration, helping expel food or liquid that mistakenly enters the airway.

Certain medications, such as ACE inhibitors used for high blood pressure, can cause a dry cough as a side effect. While coughing is usually protective, chronic or severe coughing can cause complications like sore throat, chest pain, and even rib fractures. Understanding the cause of a cough is essential for proper treatment and management, as it serves a key function in maintaining respiratory health.
