My brother is an electrician, working 7 days a week outdoors at a site. He says the key is to bring six big bottles of gatorade in a cooler, and eat really lightly.
Still, that must absolutely suck. I was walking my dog this morning at 6:30 and it was already ridiculously hot. I had to go to work with sweaty pits and an afro from the humidity.
