Cough is one of the most common symptoms affecting people of all ages. While often perceived as a minor inconvenience, cough is actually a protective reflex designed to clear the airways of irritants, mucus, and pathogens. Most coughs are temporary and resolve on their own, but some become persistent, disruptive, and concerning.
A cough may arise from infections, allergies, environmental exposure, digestive issues, or chronic respiratory conditions. Understanding the type and cause of a cough is essential for choosing the right approach to relief and preventing complications.
This article provides a comprehensive, solution-oriented explanation of cough, covering its causes, types, symptoms, nutrition, lifestyle strategies, yoga, pranayama, and preventive care.
