As wildfires continue to burn in parts of the United States, state public health officials and experts are increasingly concerned about residents’ chronic exposure to toxin-filled smoke.

This year has seen the most wildfires of the past decade, with more than 56,000 fires burning nearly 7 million acres nationwide, according to the National Interagency Fire Center. While the total area burned is less than in some recent years, heavy smoke has still blanketed countless communities throughout the country.

Climate change is causing more frequent and severe wildfires, harming Americans’ health, pointed out Dr. Lisa Patel, deputy executive director at the Medical Society Consortium on Climate and Health, which raises awareness about the health effects of climate change.

“The data we have is very scary,” she said. “We are living through a natural experiment right now — we’ve never had fires this frequently.”

Patel sees the effects of wildfires in her work as a practicing pediatrician at Stanford Medicine Children’s Health, treating more women and underweight and premature infants at the neonatal intensive care unit when wildfires rage in Northern California.

As researchers focus on the public health impact of wildfire smoke, state health and environmental officials across the country have had to issue more air quality notices and provide guidance and shelter for residents struggling during periods of heavy wildfire smoke. And as experts have found, this issue isn’t isolated to the West Coast — it hurts more residents in the Eastern U.S.

Studies show that chronic exposure to wildfire smoke can cause asthma and pneumonia, and increase the risk for lung cancer, stroke, heart failure and sudden death. The very old and very young are most vulnerable. Particulates in wildfire smoke are 10 times as harmful to children’s respiratory health as other air pollutants, according to a study in Pediatrics last year. Read More
