Smoke from wildfires is well known to exacerbate health problems like heart disease, lung conditions, and asthma. People living in the vicinity of where fires occur face these dangers. But a new study at the University of Maryland has found that there are health impacts from wildfires occurring thousands of miles away.
During the summer of 2023, massive Canadian wildfires created a vast plume of smoke that drifted more than 2,000 miles across the country resulting in poor air quality across the entire East Coast of the U.S.
Baltimore had very dark skies over a six-day period in June 2023, sending many individuals to doctors’ offices complaining of breathing issues. University of Maryland researchers found that medical visits for heart and lung problems rose by nearly 20% during that period.
Using satellite and EPA data combined with electronic health records, the researchers found increased likelihood of patients going to the doctor for complications related to cardiopulmonary conditions during the days with the most smoke in the air. They found a 55% increase in the risk for an outpatient visit for heart and lung conditions and these additional patients tended to be older, non-smokers, and more socio-economically affluent than the typical patients who see their doctors for such conditions when the air quality is good.
With more climate-related events likely to occur in the future, doctors may require better tools to help disadvantaged patients on so-called hotspot days when conditions are most dangerous. Increasingly common wildfires are a particular danger to people even when those fires are far away from where they live.
