SALT LAKE CITY — When inversions trap dirty air over Utah, how do you know when your cough comes from the gunky air or something else?

Intermountain Health Respiratory and Critical Care Physician Denitza Blagev said COVID and inversion-related health problems are two different things.

Conditions like COVID, the flu, a cold and RSV all exist outside of an inversion. Same with chronic conditions like asthma or COPD.

When inversions bring pollution to the ground, we breathe it in. That makes it easier to get sick and can make current conditions worse. 

No matter your health right now, those pollutants will affect your breathing. 

According to, health impacts of poor air quality include respiratory issues like wheezing and coughing, shortness of breath, asthma attacks, worsening COPD and even lung cancer.
