11 Respiratory Health Tips for Better Lung Function
5. Protect Yourself from Outdoor Pollution

Air pollution can reduce lung function and worsen breathing, especially during seasonal smog or wildfire smoke events. Check the local Air Quality Index (AQI) before outdoor exercise and avoid heavy exertion when levels are unhealthy. N95 or equivalent masks reduce fine particle exposure when you must be outside in poor air. Plan outdoor activity for early morning or locations with better air flow, like parks with trees, and pick indoor workouts when AQI is high. If you live in areas with frequent pollution episodes, consider routes that avoid busy roads and idling buses. Commuters can reduce exposure by keeping car windows up and using recirculated air in traffic. Parents should be mindful of children’s outdoor play during high pollution days. For urban residents, community-level measures—tree planting, public transport choices and reducing open burning—help protect everyone’s lungs over time. If you have respiratory disease, follow your clinician’s extra precautions on high-pollution days and keep rescue medications handy.
