I was kind of surprised, where I am those are pretty normal temperatures, not for weeks on end but it can hit like that for a few days in a row. We're expecting higher temperatures this weekend.

Many Iranian cities and towns have suffered from temperatures above 40 degrees Celsius (104 Degrees Fahrenheit) in recent days, while the oil-rich southwestern city of Ahvaz hit 50 degrees Celsius on Tuesday. [122F]

The capital city of Tehran experienced temperatures of 39 degrees Celsius on Wednesday.

I just checked and their nightly lows are in the high 80sF so that sucks for sure. That 122F high is bonkers though, that's pushing death valley territory. But overall it's not worse than Arizona has been going through for like more than a month, highs above 110 and lows in the 90s. Greece's heatwave seems like it is about on par to what Iran is going through, and I don't remember hearing about them shutting down the country, just limiting outdoor work and deliveries during peak heat hours.

But like you said, A/C might be a difference maker. I don't know what Iran's climate control availability is like, and this article didn't say.
