"Protecting Yourself from Poor Air Quality During Wildfire Season"

Experts advise against outdoor exercise in areas affected by smoke from the wildfires in Canada, especially for people who suffer from chronic respiratory conditions like asthma. Smoke from wildfires includes a mix of particles, some of which are microscopic and can travel deep into a person’s lungs and bloodstream. Smoky conditions can also hinder visibility and cause athletes to run slower. Several days’ worth of polluted air could have a cumulative effect, lowering an athlete’s threshold for symptoms. People should follow their city’s health advisory regarding air quality and consider running another day.
