And to what temperature do you set your AC in the summer?
If it's in the 80s outside, I'll probably drop the inside temp to 76, again to keep humidity down. I rarely set it below that. 74 feels cold in my normal summer attire of shorts and a tee shirt. If we have an 80 degree day with low humidity, I'll open the windows.
The thing about the nations I mentioned is that they either barely use any AC, like Switzerland, or set it to 25°C or more, like Japan.
They embrace discomfort - most of the world does.
