I'm hoping someone here can resolve a disagreement between my wife and
I. We have an ongoing argument about the use of household fans:
ceiling fans, pedestal fans, window fans, anything that moves air
around. She does not like them and swears that they *cause* asthma.

I say that is nonsense. To say that a fan *causes* asthma is to simply
say that *moving air* causes asthma, in which case simply going
outside in the wind would *cause* asthma.

Neither of us have asthma.

All other factors being equal, is there any basis whatsoever for
saying that the use of fans indoors can *cause* asthma in an otherwise
healthy adult?
