People who spend all their time inside with AC would not do well if suddenly they had to deal with 108. But people who spend more time outside can adapt better and learn methods to help cope. Of course that has a limit, the discussion about wet bulb temps in India and Pakistan last year was about the limit of where healthy people can function. But it doesn't take that much heat to make life hard for old people.

I have family in a place that is ususally above 100 in the summer. When I go there from a temperate location I struggle. But after a week or two I am more able to help with yard work, or taking the kids out to the park. If I spend a month the high temperature becomes fairly normal.

I spent 9 months in a location where it would commonly get to 110 by 10am. I was generally outside and commonly doing manual labor. I didn't acclimate at all. It isn't a universal thing.

To this day I don't handle hot weather well, and I don't mean 110. Anything above mid 70s is very uncomfortable and I sweat profusely and get irritated. This includes sleeping, during the warmer months I always get soaked in my sleep. I drink a lot of water too but it doesn't help.

Spent a couple hours in 95 degree heat full humidity. Had partial but not full shade. Full heat stroke. Took hours to get my heart rate below 130. Many days to recover.

I’ve done more time in the sun working out (moving) and been totally fine. Difference is I drank huge amounts of Gatorade.
