When wildfires burn, the smoke can travel long distances and degrade air quality far away, presenting risks for those breathing it.
Fires burning in one state can make air worse several states away, and wildfires in Canada can send smoke into U.S. cities.
Here’s what to know about taking precautions against poor air quality due to wildfires.
The EPA’s Air Quality Index converts all pollutant levels into a single number.
The lower the number, the better. Anything below 50 is classified as “healthy.”
Fifty to 100 is “moderate” while 100-150 is unhealthy for “sensitive groups,” and anything above 150 is bad for everyone.
Sensitive groups include people with asthma, lung disease or chronic obstructive pulmonary disease.
Dr. Sanjay Sethi, chief of the division of pulmonary, critical care and sleep medicine at the University of Buffalo’s medical school, recommends precautions for those with heart or lung problems.
In situations of bad air quality, wearing an N95 mask is advised.
Even if the pollution is not visible, it can still be harmful to health.
The EPA and companies like PurpleAir offer resources for monitoring air quality, both outdoors and indoors.
Experts suggest measures like using air quality monitors, wearing masks, and improving indoor air circulation to protect against the effects of poor air quality.
