Q What environmental factors trigger or worsen sinusitis?
A Dry air, house dust mites, pollen, mold, and air pollution are the main environmental triggers. Maintaining indoor humidity at 50-55% and ventilating the space are key.
Detailed Answer
Major Environmental Triggers
- Dry air: reduces mucosal cilia movement and hardens mucus, obstructing drainage
- House dust mites, pollen, pet dander: trigger allergic rhinitis, which sets off a chain reaction in the sinuses
- Mold (Aspergillus and others): causes allergic fungal sinusitis
- Air pollution and fine dust: damage the mucosal barrier and sustain chronic inflammation
- Swimming and diving: water-borne bacteria can enter the sinuses
Practical Management
Keeping indoor humidity at 50-55%, washing bedding once a week, using an air purifier, and rinsing the nasal passages after going out can greatly reduce these triggers. At Dongjedang, we plan environmental management together with immune-strengthening prescriptions.
