A new study finds that high levels of pollution may contribute to headaches.Researchers in Chile found that on days of elevated air pollution, more people were admitted to hospitals for migraines and other types of headache.

They found that when levels of ozone and air pollutants associated with gasoline and natural gas rose, so did hospital admissions for headaches.

The study's authors say costs associated with poor air quality should include headache-related illnesses.
