bossito‘Hell on earth’: Phoenix’s extreme heatwave tests the limits of survival
md5cryptoPhoenix never should have been the cite of a major city. Whoever is there right now has to be thinking - how the hell do I get out of this hellfire?
rockerFor those of us that have been here for many years (half my life and I'm in my 40's), its not bad. Yeah, its very hot and very dangerous, but we know how to live in it and take care of ourselves for the most part. By mid-morning, all the humidity is burned off and I actually think it feels kind of nice.
Understandable. Heat + humidity is the real problem. Relevant wikipedia article:

TLDR:
Hot + low humidity -> sweat easily evaporates, your body is able to regulate your temperature.
Hot + high humidity -> sweat doesn't evaporate, your body slowly fails to regulate your temperature, and you get hotter and hotter till you pass out or die.
30C/86F at 99% humidity is the equivalent of 50C/120F at 20% humidity. You're no longer able to sweat fast enough to cool down if it gets hotter/more humid.
