As a matter of fact, prisoner, I moved here from Houston. I’ve heard lots of people - particularly my in-laws - use the line that it’s easier to breathe cold air than hot air, but I don’t find that to be true for me. Now, in Houston, I really hated breathing humid air - and that was true whether it was hot or cold. However, given the choice between hot dry air, and cold dry air, I find the hot dry air agrees with me more. Obviously, people vary.
A funny note about Houston being the fattest city in America. I remember that coming out in some magazine, and I know their criteria was measuring the number of restaurants, and the number of fitness centers/gyms, and comparing them to the population. Houston has a lot of good restaurants - which I didn’t fully appreciate until I moved here. Also, the gyms tend to be these huge enormous friggin places, so I’m not surprised there are fewer of them. Overall, I wasn’t surprised at the result, and I question the methodology.
However - my wife heard on the radio recently [CAUTION: ANECDOTAL EVIDENCE AHEAD, NO CITE, DANGER WILL ROBINSON] about the result of an air study in Houston. Houston also has (more objectively) one of the worst ratings in the US in air quality. One of the components found in Houston air? A certain type of fat - apparently ends up in the air from outdoor grilling/BBQing, or something like that. (I’ve been dying to find the source of this to read more about it, without luck so far.) We got a good laugh out of this - we lived there many years, and we aren’t exactly thin. You know those people who seem to gain weight just by breathing? Well, apparently, in Houston, you can!
