I agree. I have lived in hot, humid places without air conditioning. The only solution is to find cool places (in the shade, in a cellar), stay wet, drink lots of water, and avoid physical exertion until the sun goes down.
I am spoiled now. I live in a region with cheap, low-carbon electricity (almost entirely from hydro, nuclear, and wind) and modern infrastructure, so air conditioning is standard practice. I wish the whole world could have the same.
