Sweat is a remarkable substance, but it has only been made clear to me recently how remarkable. For the present I live in an exceptionally humid part of the world; my sister traveling in India says it is hotter here in the States on our parents' farm than it is in Mumbai. Annapolis is a comparable level of heat, and in both places one sweats at the slightest movement, even when one is reading.
Sooner or later this frustrated me and I felt restless. So in the hottest part of the day I went for a run. Predictably the sweat covered me entirely and when I came back I was wet indeed. For some reason I did not take a shower but sat happy as a clam in front of my bedroom fan. The sweat rolled off me, and when I dried something was different: the humidity did not affect me and I even shivered from the breeze.
Now this was something wholly unprecedented and I was unsure how to take it, aside from the sheer joy I felt. I knew a run in cold weather made tolerating the cold inside (I keep my house at fifty-five degrees in the winter) easier, but never dreamed that exercising in hot weather caused one's body to cool itself more efficiently, despite knowing, as we all do, that sweat is the method by which our body cools itself. I mean, duh. I even eventually showered and everything stayed the same. So I suppose this means I have adjusted from the desert to the humid plains, and shall have no more difficulties. Needless to say, this pleases me, and makes me turn an appreciative, benevolent eye to that once odious substance which now signals relief from the fire of the sun.
