It is perfectly possible to walk in that heat if you know what you're doing. I've done it frequently and come to no harm. Millions of people live and work in that kind of heat all their lives.
And if you’re used to it..
Dh once scared me to death after we’d been sightseeing in Athens. It was incredibly hot and humid, we were both dripping and exhausted, and about to return to our hotel, when he insisted on climbing dozens of steps to a temple within the ancient agora.
Not long afterwards we crashed out in our hotel room, where I was soon woken up by his weird, alarmingly noisy, stertorous breathing. I dare say it was ‘just’ heatstroke, but I had to wake him up, convinced he was about to die on me.
Thankfully I think he’d have more sense nowadays, than to over exert himself in such heat and humidity.
