ORIGINAL: khmark7 5°F this morning and several of us from the running group are meeting for a run today. Stout hearts are showing... Karl, serious question - does running in very cold air ever bother you, as far as affecting your respiratory system to the point that it makes it hard to run that day, or in subsequent days? I used to run, and have read that the air is sufficiently warmed by passing through the nose or mouth, bronchial tubes, etc. that "freezing the lungs" or the like really does not happen and is not a concern, unless one would be facing Antarctica-like conditions of -70 air temp. or something. Still, with temperatures from -10 up to around 20 (-23 to -7 Celsius), just breathing heavily in that air would have me coughing, spitting, blowing my nose. Not all the time, and some of those winter runs were really great - silent country roads, snowflakes drifting down.... But enough that you saying "5°F" made me think of it right away. "Frozen Lung" is a myth. Lungs are fine. I didn't even cover my mouth this morning, and felt just fine running 7 miles, although next time I run in those temps I will need more insulation in my.....erm....privates region. Just sayin' Some of the guys had hand warmers, but I find that after a mile or two your hands and feet feel fine. What was interesting was how frost formed all over everybody with water evaporation. With lows expected down to around zero tonight I am more worried about my Cabernet Sauvignon vine!
