Oh, so everybody stays out in the hot sun all day? Nobody stays in the shade? Nobody goes indoors? Nobody has houses designed to stay reasonably cool when it's hot out? (There are plenty of ways to do that without A/C.)
If people don't change how long they stay out--just go out for short periods to do something, then go somewhere where they can cool off--I have no objection to them using a device to help them feel more comfortable. But uncoupling your natural perception of your body's condition from the actual state of your body is always risky.
