Association of outdoor temperature with lung function in a temperate climate

What is it about?

We examined the relationship between outdoor temperature at the home address of more than 5,000 adults living in the temperate climate of the Northeastern U.S. and their lung function. We found that lung function was on average lower when temperature was higher, especially during the winter and spring seasons. We did not measure behavior, but we speculate that the link between outdoor temperature and lower lung function may be explained by greater exposure to the outdoors (and therefore also pollution, pollen, mold, etc) on warmer days.
