Exposure to higher levels of PM2.5 particulates can also trigger cough, nasal congestion, sore throat, conjunctivitis, headache, dizziness, fatigue, skin irritation, eczema, and mild irritation of the eyes, nose and throat. Children, pregnant women, the elderly, and patients with existing lung and heart conditions are most vulnerable.



Other persons may experience only minor effects from short-term particulate exposure like irritations of the eye, nose, and throat.



Those experiencing difficult breathing or painful irritation during times when particulates are high are advised to see their physicians immediately.



How to protect yourself. Since avoiding outdoors is unrealistic, wearing masks are the next best way to protect against inhalation of smoke and other fine pollutants in the haze from the forest fires.
