Air pollution can make asthma symptoms worse and trigger attacks. Symptoms of asthma include coughing, wheezing, difficulty breathing and chest tightness. Even individuals who do not have asthma could experience these symptoms.
The individual might need to take a break, do a less intense activity, stop all activity, go indoors, or use quick-relief medicine as prescribed. If symptoms don’t improve, get medical help.
