By Dr. Navaneeth K. Unni•Published on 2026-07-01•Patient Group: Adults
Clinical Overview & Pathophysiology
Air pollution is a growing respiratory concern. Exposure to particulate matter (PM2.5) and outdoor allergens can trigger asthma attacks, rhinitis, and chronic lung irritation.
Key Clinical Facts & Indicators
- Bronchial Hyper-reactivity: airway irritation triggering wheezing and dry cough.
- PM2.5 Damage: Fine particles penetrating deep into lung tissues, causing inflammation.
- Indoor Air Quality: Dust mites, mold, and cooking smoke worsening respiratory symptoms.
- Chronic Congestion: Persistent post-nasal drip and sinus pressure.
Lifestyle & Nutritional Guidelines
Improve respiratory health by using air purifiers, keeping windows closed during peak pollution hours, and wearing masks outdoors. For personal respiratory support, refer to our Asthma and Allergy care guides.
Frequently Asked Questions
Q: How does PM2.5 affect the lungs?PM2.5 particles are small enough to pass deep into the lungs and enter the bloodstream, causing systemic inflammation.
Q: How can I improve indoor air quality?Ensure proper ventilation, keep the home dust-free, avoid heavy incense or room sprays, and use HEPA air purifiers.
