Based on weather data from January 1, 2007 to December 31, 2019 the researchers found that contrary to many public health recommendations—including from the World Health Organization (WHO)—electric fan use for effective cooling without air conditioning could have been universally recommended for young healthy people during peak heatwave conditions in all populous cities in Bangladesh, China, Japan, Philippines, Indonesia, Canada, eastern regions of the USA, all of South America and Oceania and most of Europe (excluding some Mediterranean cities).

Fan use alone should not have been routinely recommended during hot weather in northern India, Pakistan, the Middle East, and the southwestern regions of the USA, because it would have regularly worsened heat stress.

You don't need air conditioning. A simple fan will do. You'll own nothing and be happy.

Actually in the dry SW, swamp coolers are useful. They add moisture/humidity.

They work great until you hit the mid-to-high nineties in monsoon season. Then they don't. They work the least in the time you want it most. The higher humidity (granted nothing like the anything outside the SW) we get in the Albuquerque area during monsoon makes swamps pretty much useless except as air movers.

Our family lived in Pune, India for two years. In the hot, dry weather just prior to the monsoon, it would regularly get to 110F in our apartment even with all the curtains drawn to keep out the sun. During the hottest part of the day we would read by pulling our chairs under the ceiling fan and pouring water on the terrazzo floors underneath us. Then we would sit with our feet in the puddles until all the water evaporated. Now maybe in a scientific sense it wasn’t cooler, but it sure felt like it! :-)
