We have ceiling fans in most every room, and open the windows alot, but once the temps outside hit close to 80, I become non functional, and MUST seek shelter or sit in someone's fridge. Mine is normally set on 72, but I will lower it to keep me blasted if I am having a tough day. Once it starts heading towards 75 and above outside, I seek shade, and cooler spots, once it hits 80 I am inside, and in the dark. After that, its all shades down, curtains closed, and AC blasting.
