I think it has more to do with where you grow up and what you're acclimatized to...

I was born in Feb in VA - it was a year that had a lot of blizzards, and summers are always hot & humid. I don't typically use the AC and don't mind the heat - but I also love to ski and after a couple days of skiing, I'm talking around in long sleeve shirts at the base of mountains 'cause it feels hot to me compared to the temps at the top.

I do overheat easily while exercising.
