CHICAGO -- NBC5 reported that a lot of asthma patients believe their condition worsens during a thunderstorm. Now there may be some explanation why.

Allergists say part of the cause could just be the wind, which blows allergens up into the air and even into the home.

"All sorts of debris that's been in the ground gets blown up and, as people with sensitive airways breathe in some of that debris, they often start wheezing," said allergist Dr. Dennis Ownby.

NBC5 reported that another reason for the increase in respiratory distress is wet grass. Rain causes pollen on some grasses to virtually explode.
