FWIW, A conditioning in the desert doesn’t promote acclimatization. Summer colds are much more common when troops/Marines are garrisoned in air conditioned environments, instead of cooled by evaporative cooling.
Many package units are designed to cool to a differential temperature of about 40 degrees. 120F outside, 80 degrees in AC. 130F outside, 90 deg AC.
Swamp cooling tends to reduce the temp by about 15deg-25 deg, but provides 3X as much ventilation. The perceptible temperature is more efficiently influenced by the cooler air flowing over the body, instead of the entire environment being reduced in temp.
IOW, It’s healthier for the grunt to live with swamp cooling in the desert.
We routinely keep the AC in the 77 degree range as we have to work outside part of the day. Avoids the shock of temp change, and, yes, it does save money. No reason to keep a home at a temperature where you can’t tell the difference between the living room and the refrigerator ( bit of an exaggeration, but...)
What you say is true. I live in SW Colorado (high desert country). Swamp coolers are far more effective than AC.

Unless it's rainy season. Then it's really miserable.
We had a swamp cooler in NM. It was not a very good way to keep the house cool. On the contrary. We keep our air at 80 or above in Arizona. With temps as high as they are this week, our a/c would be running around the clock. Well, with night time temps I n the 80s, it is running constantly. We could not do this in a humid environment. But I am guessing that Afghanistan is not humid.
Our friends with swamp coolers in this area hate them.
I have to keep a cool mist humidifier running when it is so hot and dry outside. It says to only put cold water in the machine. There is no such thing as cold water at this time. The water out of our taps is very warm to hot all the time. It does save on the gas water heater.
