It's not going to be a pleasant couple of days but many people do go on holiday (willingly) to countries that have these temps. I certainly sunned myself in 35C years ago when I was young and silly.
The key word being holiday. Where you don't have to work, commute, wear particular clothing, can do as you please, and often have frequent access to the pool or the ocean. It is not comparable to living and working in a city.
You could argue that our homes are not built for extreme temps
There is nothing to argue. Our homes are, in the main, not built for extreme temperatures, in the same way they're not built for earthquakes or deep snow.
but it's only for a couple of days.
Exhaustion and heatstroke sets in much quicker than that.
TBH most of the people who do suffer are elderly, have pre existing health issues, or think it's a good idea to jump off bridges into rivers, or sun themselves on beaches.
That doesn't make their suffering less valid or important.
