People who are sensitive to air pollution, such as older adults, children, and those with heart or lung disease, should avoid prolonged or heavy exertion outdoors, consider moving activities indoors or rescheduling to a time when air quality is better, and stay indoors as much as possible.

Air pollution can cause symptoms, even in people who are healthy. Symptoms can include coughing, wheezing, shortness of breath/difficulty breathing and chest tightness or discomfort with activity or deep breaths.
