MONTREAL — Overweight and obese adults breathe up to 50% more air per day than adults at a healthy weight, which makes them more vulnerable to air contaminants that cause asthma and other diseases, University of Montreal researchers have found.
The extra air exposes them to larger amounts of ammonia, ozone, nitrogen dioxide and other irritating elements, the study says.
Children who pack on extra pounds breathe up to 24% more air than children of normal weight, the researchers found.
"The situation for obese children may be even more worrisome," the university said in a statement.
The study was published in the journal Risk Analysis.
