Loma Linda residents often spend time outdoors along busy commute corridors and neighborhood routes, and many households include children, older adults, and people with chronic respiratory or heart conditions. During wildfire season, the combination of:
- Frequent short trips (groceries, school drop-offs, appointments)
- Walkable community activity and time spent near busy streets
- Indoor air quality differences across older and newer homes
- High exertion moments (yard work, walking, commuting)
…can increase exposure during the hours when smoke is worst.
Also, wildfire smoke can travel far. Even when the fire isn’t nearby, Loma Linda can still experience elevated particulate levels for days. That’s why symptoms that start “out of nowhere” during a smoke event may still be tied to what you breathed.
