How do people survive in Texas?

Ok, maybe the title is a bit misleading, but this is something I've been wondering about forever. I would have put it in H/A, but it might qualify as Discourse. :|

Anyway, I don't understand how it is possible for humans to survive in temperatures hotter than our core body temperatures (around 37C or 100F). As far as I know we have many ways of heating ourselves (putting warm clothes on, burning fat, etcetera), but very few of cooling ourselves outdoors on 40C days. I may be wrong, but I thought that sweat only cooled us because the cooler air exchanges heat with our skin when the sweat evaporates. If the air is warmer than our skin, then I would think this effect would disappear.

So educate me D&D - how is it possible for humans to survive in temperatures higher than our internal body temperatures? Is it even possible indefinitely?

    Yep, sweating causes you to shed heat pretty efficiently, even if the outside temperature is hotter than your body.

    So the idea is that your body provides a large part of the energy that is required to change the liquid sweat on your skin into gas?

    That makes sense.

    Also, 500 dollar electric bills in the Summer. No exaggeration. But the sweet joy that is central air is worth it.

    Holy crap, 500 bucks? How inefficient is your A/C unit...and is your house one giant window?

    I think the highest we've had in our 1500 sq. ft. house is $200 in August. And I keep it pretty cold at night.

    Yeah, evaporation is an endothermic process. It cools down the surface it evaporates from. If you want to go all Mr. Wizard/Bill Nye, swab some rubbing alcohol on your arm and blow on it. Since the alcohol evaporates quickly, the coolness is much more noticeable than it is with water.

    Is it true that new houses in the southern states are built pretty much completely devoid of any sort of insulation? I've heard anecdotes about houses being built there with four layers to the walls, from inside to out: drywall, 2x4 stud, plywood and exterior coating x like stucco. If true, this seems like completely lunacy if there's going to be such a huge temperature gradient between exterior and interior temperatures.

    Probably depends. Most newer homes have good insulation. I know some of the older apartments we used to live in had pretty crappy insulation.

    For the most part that is bullshit
    Insulation is as important for keeping heat out as keeping it in

    My wife and I used to live in an attic apartment without air conditioning. All the heat from the house would rise on summer nights and make it into an oven. We would be awake at two in the morning mixing rubbing alcohol and water and rubbing it on ourselves with face clothes trying to prevent heat stroke.

    I suspect your body also has mechanisms for moving heat into a hotter reservoir. This is completely unscientific and based solely on the fact than when I breathe on my hand at 110F, my breath still feels hot (if I'm wearing body armor or otherwise making it necessary for my body to work really hard at cooling off).

    No shit. I spent time at Fort Polk in the summer...human beings were not meant to live there.

    Oh, and all that "it's a dry heat" shit you hear about the desert (whether Texas, Arizona, wherever) largely matters because the less humid the air, the more quickly your sweat evaporates and the more effective it is at cooling you...also, the drier the air the more effective simple shading is.

    Honestly, Louisiana was the first place I've been that I thought was largely uninhabitable to humans, because your sweat quite simply doesn't evaporate. After a while outside you look like you've gotten out of a damn swimming pool. I have no idea how our body can survive in ambient temperatures that high when it's that humid, but here I am so I guess that's possible as well.

    I realize that was a joke, but it was more about shipping off the lower class rather than getting rid of the criminals. Neat stuff.

    Exactly. Heat doesn't bother me, it's that "Oh god I'm soaking wet and sticky I just want to take a shower" feeling that bugs the shit out of me in Louisiana summers.

    Humidity matters. A summer in Texas ain't shit compared to a summer spent on the coast in Louisiana or Mississippi.
