LOL. Geez, first one doesn't stand a chance in this bunch. lol. The topic on this thread should have been "It was so hot, fill in the blanks".
Being more serious, the #1 thing you can do is acclimate yourselves to the environment. You cannot sit in A/C all week and go out into the sun and expect to tolerate the conditions without issues. Your problem with the heat will never be as great as the next guy. Most of the time it is your fault unless you have a medical condition that you cannot control. In that case, the environment will not be conducive to your health and this sport played outside in the summer is not for you. Sorry.
Turn off the A/C. Open the windows. Put you sunscreen on and go outside. Live in it daily and soon it will be a mute point. Take the necessary precautions, use common sense, and learn how to live in the elements. Hot is hot, cold is cold, but it's not a deal-breaker if you do the right things to prepare.
Farmers baled hay and straw all day, all summer, in Levi pants and a straw hat. We shared the same water jug filled with tap water to get a drink. We fought to get a drink before my dad or the hired help drank out of it first because they chewed tobacco and we didn't want to taste their spit. We ate lunch from a brown-paper bag that had sandwiches made the night before and the bag spent the morning under a tree or in the cab of a truck sitting in the sun with the windows down. We would blow the chaff off the bag and sit on a fresh bale of hay under a tree. Those that couldn't get into the shade of the tree spent lunch sitting under the wagons in an effort to get out of the sun. What a treat a breeze was if it didn't fill your eyes with dirt. At least the blow-torch hot air blowing over your body wringing in sweat made you feel better for a few fleeting moments.
See, my story is worse than yours........................
