We have multiples of these for keeping our dog cool in desert climates, but they can work for humans, too.
The temperatures reached by such devices are equal to air conditioning, though of course you need to be directly in front of the device. All you do is pour in water and they run off USB power or battery power to chill the water, which creates a chilled breeze. (No water is sprayed out. This is generations-old tech that works.)
We have used these devices to keep our dog cool for example when we enter a super hot car and wait for the air conditioning to cool off the car enough from desert heat, meaning temperatures of 100 degrees Fahrenheit or more (37 degrees celsius or greater).
There are a bunch of different makers of such devices and they’re easily available on Amazon or other places. If I were on a boiling hot sit without air conditioning or central air, or even a fan, I would order one of these. They are roughly the size of a lunchbox.
