Health Impacts of Wildfire Smoke
Wildfire smoke poses significant health risks due to the fine particulate matter, known as PM2.5, which can penetrate deep into the lungs and enter the bloodstream. This pollution is linked to a wide range of health issues, including respiratory diseases like asthma, cardiovascular conditions such as heart attacks, and mental health disorders. A recent study revealed that more than 11,000 deaths annually in the U.S. can be attributed to PM2.5 from wildfire smoke, emphasizing its extensive public health impact. Notably, those living far from fire sources face heightened mortality risks, indicating that wildfire smoke is a national concern, not limited to regions directly affected by wildfires.
