Allergies and Pollution: Are They Related?

Yes — very much.

Air pollution in Indian cities (PM2.5, dust, smoke, traffic fumes) is a major trigger that worsens existing allergies and increases the risk of developing new ones.

How Pollution Affects Allergies

• Irritates the nose and lungs → makes them more sensitive to allergens.

• Breaks pollen into smaller particles → deeper entry into airways, stronger reactions.

• Carries allergens like dust mites & spores on pollution particles.

• Prolongs pollen seasons due to climate change.

• Triggers asthma even in non-allergic individuals.

Who Is Affected Most?

Children, adults with asthma, people with dust/pollen allergy, and those living in high-traffic or industrial areas.

How to Protect Yourself

• Check AQI daily; avoid outdoor activity on poor AQI days.

• Use N95 masks outdoors.

• Keep windows closed on bad AQI days; maintain clean indoor air.

• Continue your allergy/asthma medications regularly.

• Get a detailed allergy evaluation if symptoms persist.
  
  

Conclusion: Pollution doesn’t cause allergies by itself, but it makes allergic diseases much worse. Managing exposure and optimising treatment can significantly improve symptoms.
