When Elvis Presley would stay in Las Vegas then he used to put aluminum foil on the windows of his hotel room so that he could sleep with the air conditioner on during the heat of the day, and then perform during the cool of the night. They could tell which room Elvis was in because of the aluminum foil on the windows.
I think Palm Springs in California has some businesses that are open 24 hours per day as well, so that people can sleep during the heat of the day with the air conditioner cooling their home while they sleep, and then they can work and shop at night, etc. Plus they have swimming pools.
Right now lots of people are moving to Arizona and to New Mexico, and they could benefit from having a 24 hour schedule in the heat of the summer, etc. And in Mexico they sleep during the heat of the day and they work when it is cool, they take a siesta in the heat of the day.
I was born and raised in the desert of California, in Lancaster, and the secret is to drink lots of water, you need to stay hydrated. I never had a problem from the heat. But the desert nights were fantastic, I loved the nights in the desert, we used to party all night, back when it was all cool people from the Space Shuttle program, etc. The desert was like a resort when I was young. I loved the desert as I was growing up. And my first car was a VW Baja Bug, it was great, I used to do 100 mph across the desert.
That is my advice for people moving from New York and from New Jersey, etc, to the desert in Arizona and in New Mexico, and Nevada, etc, is to try to work at night, and sleep during the day with the air conditioner running. And be sure to have a swimming pool.
Salute,
