In Southern California, wildfire smoke often arrives in waves—sometimes overnight, sometimes during commute hours when people are already exposed outdoors or in vehicles with HVAC running. For residents, the hardest part is remembering the sequence: when the air quality worsened, when symptoms started, and what you did to protect yourself.
That timeline matters legally because insurers frequently challenge causation by pointing to other triggers (allergies, indoor irritants, viral illness, or pre-existing asthma). A well-documented chronology helps show your illness tracked with the smoke event rather than random timing.
What we typically request from Glendora clients early on:
- Dates you first noticed symptoms (coughing, wheezing, chest tightness, shortness of breath)
- Where you were during heavier smoke periods (commuting, outdoor errands, school pickup)
- Indoor conditions (how often windows were open, whether HVAC ran on “recirculate,” filter type)
- Medical visits and clinician notes that reference air quality or smoke exposure
