New study reveals wildfire smoke linked to staggering 24,100 deaths annually in the U.S.

"Chronic exposure to pollution from wildfires has been linked to tens of thousands of deaths annually in the United States, according to a new study. The paper, published Wednesday in the journal Science Advances, found that from 2006 to 2020, long-term exposure to tiny particulates from wildfire smoke contributed to an average of 24,100 deaths a year in the lower 48 states."

"The paper's researchers focused on deaths linked to chronic exposure to fine particulate matter, or PM2.5 the main concern from wildfire smoke. These particles can lodge deep into lungs and enter the bloodstream. Short-term exposure can trigger coughing and itchy eyes, but longer term, they can make existing health problems worse and lead to a range of chronic and deadly health issues, including respiratory illness, cardiovascular and neurological diseases, and premature death."

Chronic exposure to fine particulate matter from wildfire smoke caused an average of about 24,100 deaths per year in the lower 48 U.S. states from 2006 to 2020. Wildfire smoke PM2.5 can lodge deep in the lungs and enter the bloodstream. Short-term exposure triggers coughing and itchy eyes, while long-term exposure worsens existing health conditions and contributes to respiratory, cardiovascular, neurological diseases, and premature death. Wildfire smoke has become a significant and growing environmental hazard driven by more frequent and intense wildfires. Multiple, varied studies are needed to increase scientific confidence and inform public health responses.
