Thanks for researching that. I didn't think about it much, knowing that I don't like equatorial humidity all that much, but knowing that a little bit of height (even 1500 feet, where I can still breath easily) makes a world of difference. And, to a considerable extent, the human body adapts to higher elevations, IN TIME, by increasing lung function).
I am finding I handle higher humidity better than I would have thought and better than higher temperatures. A window airconditioner at nighttime may be all I need to sleep comfortably. In the day time, near 100% humidity doesn't bother me unless the temperatures are also above 90F. Put differently, I seem to cope better with 86-88F daytime high humidity way better than 100F dry. Exercising at 86-88 does make we sweat a lot, though.
I expect to get a lot more practice, later this year, as I expect to spend most of the latter half of the year in tropical locations.
