From what I recall from either a video or article somewhere, was that people also used to build their houses in ways to keep them cooler as well. The houses weren't as air tight as today and allowed more airflow. They also built two story houses with lots of windows on opposite sides of the house to catch the wind. They would then open the lower floor windows on the side of the house facing the wind, and the upper floor windows on the opposite side, to draw the heat out and replace it with the cool evening breeze. Don't remember what else there was, or where I saw it. If it turns out to be an older video if yours, I'll only be slightly embarrassed, lol.
