The question is not whether to run from a wildfire, but whether to run during a wildfire. If you or your clients are runners or simply like to exercise outdoors, there is a risk when doing during wildfires. The smoke from wildfires carries particulate matter that can cause breathing problems in the short term as well as create risk for longer-term health issues.

It’s not just your running performance that could be impacted. The American Heart Association has warned that “exposure to PM2.5 over a few hours to weeks can trigger cardiovascular disease-related mortality and nonfatal events; longer-term exposure (i.e. a few years) increases the risk for cardiovascular mortality to an even greater extent … and reduces life expectancy … by several months to a few years.”
