"Our data suggest that exposure to increased levels of air pollution over several days can trigger stroke hospitalization," said Dr. Zorana Andersen of the Danish Cancer Society in Copenhagen. "But we don't know yet how air pollution triggers stroke."
Andersen also noted that air pollution inflicted strokes are not a problem limited to the elderly and that seemingly healthy individuals can be affected.
