Winter air inversion affects kids differently than adults, especially kids with breathing problems such as asthma. On a day with heavy inversion, is it safe for your child to play outside? Pediatrician Cindy Gellner, MD, defines what inversions are and why children are more at risk during periods of bad air quality. Dr. Gellner also discusses how to decide whether the air quality is good enough for your child to be out during recess at school and what to do if it’s not.
