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.

What Is a Cough?

A cough is a reflex action that helps clear the throat and airways.

• Protects the lungs from irritants
• Clears excess mucus or foreign particles
• Responds to infection or inflammation

While occasional coughing is normal, frequent or persistent coughing may indicate an underlying issue.

Why the Body Produces a Cough

The cough reflex is triggered when sensory receptors in the airways are irritated.

• Dust, smoke, or pollution
• Infections affecting the throat or lungs
• Excess mucus production
• Acid reflux irritating the throat

Types of Cough

• Acute cough
• Subacute cough
• Chronic cough
• Dry cough
• Wet or productive cough
• Night-time or positional cough

Acute Cough Explained

An acute cough typically lasts less than three weeks.

• Commonly caused by colds or flu
• Often accompanied by fever or sore throat
• Usually self-limiting

Chronic & Persistent Cough

A cough lasting longer than eight weeks is considered chronic.

• May indicate asthma or allergies
• Linked to postnasal drip or reflux
