OK to change the subject slightly...I have an East Indian MD that suggested using a Neti pot for nasal lavage to alleviate a post nasal drip from pollen this summer...I've continued using the warm salt water nasal lavage daily, and has really helped me during the chill we are having down here... I know it is nothing like the temps you have, but my house is heated only with heat pump, and I don't use a humidifier, so I really dry out... you might give it a try... it only feels like you are being waterboarded the first time or so
