Some of us live in places where there is more sunny & hot days than not, and your advice feels geared towards people who don't live such places ;)

I'll add that in some places sunny and hot days are sometimes better spent indoors with an aircon if possible.

Excessive heat, especially in humid regions can be daunting.

Summers in my country are getting hotter and sunnier and they've had an impact on my screen use (I hate glare!).
