A new study suggests smoke from wildfires is more dangerous than other air pollutants for asthma patients.
Researchers looked at six years of data in and around Reno, Nevada, and found that high-pollution days caused by wildfire smoke sent a lot more people to the hospital for asthma.
Daniel Kiser, a Desert Research Institute data scientist, is the lead author of , which was published last month in the journal Environmental Health.
鈥淏ecause we were seeing a larger effect of particulate matter on days when wildfire smoke was present, we concluded that particulate matter from wildfire smoke might be more harmful to patients with asthma than particulate matter from other sources, such as vehicle emissions or dust,鈥� Kiser said.
The researchers examined asthma intakes at emergency and urgent care centers against data from local air quality monitoring.
However, Kiser cautions that the effects from smoke can vary widely depending on geography and how far the smoke travels, and says the study doesn't offer a blanket conclusion.
鈥淲e definitely want to be careful about applying to other regions of the country as well, since they might have different types of particulate matter in the air, even with wildfires,鈥� he said.
are above of 7.7%, according to the Centers for Disease Control and Prevention.
An historic and ongoing fire season on the West Coast has sent thick smoke across much of the Mountain West in recent weeks, even as the region as a whole has had a relatively mild fire season. Extreme wildfires and the unhealthy smoke they produce are becoming more common partly due to climate change.
Meanwhile, those with asthma are already to severe illness from COVID-19.
