Same here for me as well however I am starting to find that short brief things few minutes at a time are tolerable so long as I go back into AC and cool down. By the way I keep my home AC set at 72 during the day and 69 when I am sleeping whether I am home or not (ok, well I am home most of time anyway :-)

I went to ranch today at 6:30 pm and it was still too hot to do anything it give horses some love and apples. Stil was nice to be out for even half hour.
