FAQs
How does poor outdoor air quality worsen COPD symptoms?
Pollutants like PM₂.₅, ozone, and NO₂ irritate inflamed airways, increase oxidative stress, and can trigger bronchoconstriction, leading to more coughing, wheezing, and shortness of breath.
What indoor factors should I control to protect my lungs?
Limit sources of smoke and VOCs, keep humidity between 40‑60 %, use HEPA air purifiers, and change HVAC filters regularly to reduce dust, mold, and fine particles.
When should I wear a mask outside?
On days when the AQI is above 100 (Unhealthy for Sensitive Groups) or when PM₂.₅ exceeds 35 µg/m³. An N95 or better respirator provides the needed filtration.
Can adjusting my home AC help reduce COPD flare‑ups?
Yes. Set the AC to 68‑72 °F (20‑22 °C) and run it on “auto” with a clean filter. Add a humidifier if humidity drops below 40 % to keep mucus thin.
Should I change my medication during high‑pollution periods?
Discuss a short‑term step‑up with your doctor—often adding a rescue inhaler or increasing the dose of inhaled corticosteroids can prevent exacerbations when air quality is poor.
