I spent several years rebuilding a property in the Mojave desert, never had AC. If you don't sweat / get dehydrated, the fanned hot air is just a blast furnace and instead of feeling relief you can tell it's making things worse. But if I were elderly and that somehow affected my ability to perspire correctly even if hydrated, I'd just use a misting bottle to spray myself or repeatedly enter a cold shower. It's obviously more effective in lower humidity ambient conditions, but the body must have moisture at the surface to carry the heat away evaporating in the wind.
