You gotta be kidding! That's news to me in my experience! Heck, my brother
crossed Death Valley in the daytime a couple of times, NO AC, just some
water, but then we're made of sterner stuff.
Getting OT, visitors to Arizona too often die because they don't feel bad.
Dehydration leads to heat stroke - a visiting Briton died of heat stroke in
the Grand Canyon about a week ago apparently because it wasn't very hot and
he thought there would be some warning. There is none at all. Our retired
unit secretary was walking home from her overheated car when heat stroke got
her. She reported she was striding along, "feeling great" as she described
it, and the next thing she knew she was in the bathtub and her husband was
filling it with cold water. She was lucky - a few years ago in Phoenix a
bicyclist was talking to EMTs because he was weak and cramping, then heat
stroke set in. The EMTs couldn't save him even though they were right there
when it started.
The effects of dehydration are worst outside the car, but the dehydration
itself often comes from not keeping up while in the car. Changing a flat
tire when already dehydrated is bad news. If you are coming to arid country
learn the cardinal rules of survival: drink before you are thirsty, and stay
in the shade as much as possible. You can live without A/C (I didn't use it
when the temp was 50C about 5 years ago), but dehydration will kill you in
minutes without warning. You don't need a cupholder if you use bottled
water, but not drinking is inviting sudden death.
