Minnesota issues air quality alert amid Canadian wildfire smoke concerns

In Minnesota, on Sunday, July 13, 2025, the Minnesota Pollution Control Agency declared a statewide air quality alert effective until 9 a.m. Monday. This alert is primarily due to smoke originating from wildfires in Canada, which has significantly degraded the air quality across the state. Physicians are particularly concerned about the health implications for individuals with pre-existing respiratory conditions, urging them to minimize outdoor activities during this period of poor air quality. Health professionals, including Dr. Andrew Stiehm and Dr. Cheng Lo, have highlighted that outdoor activities become detrimental since physical exertion increases the volume of polluted air inhaled. They recommend taking precautions, especially for vulnerable groups such as children, and suggest over-the-counter medications for alleviating symptoms. Instances of increased visits to pharmacies for inhalers and remedies for dry eyes have been noted during this period. Meteorologically, the forecast indicates that there will be a gradual improvement in the air quality as winds shift back from the south. However, some air quality issues may remain, especially in northern areas. Although the immediate forecast suggests heat and humidity will rise, with expected temperatures in the upper 80s, significant rain and storm activity are anticipated following Tuesday, which might further assist in alleviating air quality issues. This circumstance underscores the broader environmental challenges posed by wildfires and the direct impact they have on public health. As Minnesota residents contend with these air quality problems, cities are also working to prepare for heatwaves and potential severe weather, striving to maintain public safety amid these environmental stressors.
