You realize that your assertions are heavily influenced by the climate of where you live, right? While what you said makes a lot of sense for somewhere like Texas or Arizona, it is completely wrong for, say, the majority of Canada.
I live in the Netherlands, our summers are probably closer to Canada than Texas and it’s still way too hot to be outside un direct sunlight during summers.
That is highly personal though; I am from NL and I have never experienced what you say. Too hot in NL is not a thing. I moved to Spain and we even usually (outside august) find it too cold there. Each his own but for a country with such crap summers like NL I find this a weird one; most people I know there take summer afternoons off to hang outside on terasses.
That and working, walking etc in the hot sun gives me energy personally; energy I missed in our Dutch winters.
