Usenet Newsgroups Winter coughing From: andymhancock@gmail.com (AndyHancock) I've always had itchy throat, but when winter comes, the cold air drys up and every little thing causes spasms of coughing.  I walk around like a freak and annoy my colleagues with it.  It is growing worse through the years.  Mostly a dry cough, but exclusively. I recently started to humidify my apartment, keeping the relative humidity (RH) between the recommended 30-50%.  The condition is better when RH is near the 50% end, but the problem seems to persists.  Now I'm beginning to wonder about the cause and effect.  I have been running a HEPA filter air purifier at home during the night, but this also coincides with the time that I stared to humidify the air, so I'm not sure if it has any effect. Two allergy tests over the past 7 years or so show that I'm sensitive to common things (horses, dust mites, cats).  There are no cats or horses around me, and I vacuum and launder regularly (including vacuuming the mattress). Family doctor can't hear anything through the stethoscope, and was in a hurry (as always). Any idea of a next step to sleuth down the problem, or another measure to take to ameliorate the problem?
