Wildfire Smoke Threatens U.S. Cities | Science News

Major U.S. cities are choking on wildfire smoke drifting in from Canada—air quality so bad it’s among the worst globally. This smoke may be up to ten times more dangerous than other pollutants, with even short exposures posing serious health risks. It’s not just lung trouble: it’s fueling ozone smog linked to hundreds of premature deaths each year, and early studies hint at mental health impacts too. Climate change is making fires worse, turning droughts and heat waves into tinderboxes. Stay indoors, seal windows, use air filters, and wear N95 masks if you must go out. Check your local Air Quality Index—and if you’re pregnant, elderly, or have health issues, take extra care. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
