Even mild dehydration can worsen symptoms.
6. Smoking and Environmental Irritants
Exposure to smoke, pollution, or chemical fumes irritates the respiratory lining.
In response, the body increases mucus production to trap harmful particles.
Chronic exposure may lead to:
Persistent cough
Thick sputum
Ongoing throat irritation
Eliminating irritants is critical for long-term improvement.
7. Respiratory Infections
Viral infections (like colds or flu) temporarily increase mucus production.
If mucus:
Becomes yellow or green
Is accompanied by fever
Persists beyond 10–14 days
Medical evaluation may be necessary to rule out bacterial infection.
