From 2009-2013 before I had A/C my room in the summer would be 95-99. Sure it sucked to sleep but that is true summer. That's why I can tolerate the heat more than most. IMO, subjecting your body to crazy temperature swings and frequently is not good for the immune system. Going from outside to A/C then back to outside and so forth...not good. It drives me nuts when you go inside places and the A/C is cranking to make it feel like a fridge.
