I had family move to the desert under the auspices of “better, cleaner air” and “a lack of pollen and allergens” because lifeless hot rocky area. A year later, during the regular torrential monsoons of the southwest, the cottonwoods and flowers suddenly bloomed and caused a solid month of air so full of pollen that it left yellow smears on all surfaces. Then the sandstorm/haboobs forced them to clean everything.
There are no good reasons to live in the desert unless you want that Edward Abbey lifestyle, away from the things of man.
