How did residents of the American Southwest deal with the heat without air conditioning?

Title. It's 98 degrees out right now, and walking two miles just about wore me out. And I'm not even doing any hard manual labor like farming or ranching. How did people back in the day (Native Americans, Spanish settlers, frontier cowboys,etc) survive in this kind of constant heat and manage to be productive?
