OH, my! I keep mine at 68! I guess that's why my electric bill was so high this past month, but I can't tolerate heat at all!
I have a ceiling fan that goes over my bed at night, as well as fans in other rooms that must be going when I feel hot. I think I'd do well in a cooler climate, like Alaska!
I do set it up to 72 now while I'm working during the day, but during the summer when I was home all day, I tried to keep it down to 68, though sometimes the AC was working overtime and not making it!
I'm so looking forward to autumn (my favorite time of year)...frosty mornings, sunny cool days with colorful leaves!
