If it's not overly humid, evaporative air conditioners are a cheap to run way to keep cool. The personal units (Convair Classic etc) are typically about 50 to 80 watts, so a single solar panel, battery and inverter should guarantee safe, grid free cooling for one or two people.

Chimney. If you have a chimney, open it.
Any air passing above will create a suction effect below and suck all the hot air out of the room.

Arabian here, uhh - it's insanely hot here too. Lol. Outside, i try to move to shade and trees as fast as possible, carry two water bottles all the time and relax in shadows when i can.
At home? ACs.
My advice isn't too useful sadly, but i hope you can use it a little.
Thank you.
how much air conditioning do you have? if you take public transport, is it air-conditioned?

Shade is everything. Tree shade is the best, because trees transpire, cooling the ground beneath them even more than shade would alone.
Inside your house (depending on what kind of home you have), you can also take a look at your overall energy efficiency, including windows, doors, insulation in walls and attic, and weather stripping to seal all gaps

There is research that shows that white coloured roofing causes increased heating elsewhere, so it's not a fix-all solution.
I live in Australia and during summer use a lawn sprinkler on the roof. Using a tap timer, it runs for 10 to 30 seconds every 10 minutes.
Just enough to wet the roof, so that the water evaporates and cools it down.
Other things you can do is growing creeper vines over a wall where the sun hits in the afternoon to keep direct sunlight off the wall.
If you have sash windows, you can open it at the top and bottom, creating a thermal airflow that will cool the house.
Adding sunshades and building housing with awnings makes a massive difference.
Lots of research associated with passive solar temperature regulation.
Thank you.

Is it that the roof would reflect it back to the sky and heat the air, intensifying the greenhouse effect or so?
Would it be better overall than homes heating up and even more energy and heat used to cool it? Or would it that be worse off?

Cool. Are there any sources that share info on the ones that would be useful and available/suitable for regular use?
