As of Wednesday morning, New York City’s air quality was 56, which is regarded as “moderate,” while major cities like Chicago — which had the worst air quality in the world on Tuesday, according to IQAir.com — are experiencing “very unhealthy” air conditions, perNBC News.
As it did on Tuesday, Chicago’s Office of Emergency Management and Communications encouraged people to limit their time outside, particularly children, teenagers, the elderly, people with heart or lung conditions and those who are pregnant.
Such precautions are necessary because the particulate pollutants in wildfire smoke are made up of solids like soot and dirt that can travel deep into lung tissue and into the bloodstream, perthe Centers for Disease Control and Prevention.
The National Weather Serviceadvises staying inside whenever possible, especially if you have respiratory issues or other health issues, limiting the time outside to strictly necessary activities and refraining from burning debris or other items while an alert is in effect.
