    I’ve been in 52 C heat (125 F) and it’s no joke, but you can still walk around, even in the sun, without exerting yourself too much.

    I’ve also been in a room at 70 C (almost 160 F) for a few minutes and that was terrifying. The air is as if burning your insides, it’s absolutely unbearable. There is a world of difference between these two. I image 60 C for four hours would start killing people, particularly the elderly.

      35c (95 f) is the wet bulb temperature where the human body stops being able to cool itself. Humidity plays a role, but generally above this temperature you’re going to get heat stroke if you can’t find external ways to cool off. So yeah 52c would definitely be enough to be killing people without a/c, fans, cold water, etc.

        Humidity plays a big role. You can still cool down at 52 C if the air isn’t very humid (that is, when the wet bulb temperature is low enough). Wet bulb temperature is a particularly useful metric because it incorporates evaporative cooling in it. Sadly most thermometers can’t measure it.

        Yeah, no. 95F is a normal summer temperature here. I’ve done farm work for hours in triple digit temps in direct sunlight without getting heat stroke.

        It’s something you have to be acclimated to, though, and you have to know to frequently drink water.
