How Did Ancient Egyptians Actually Survive the Desert Heat?

How did ancient Egyptians survive 50°C heat with no air conditioning? At Deir el-Medina, the walled village of the pharaohs' tomb builders near Luxor around 1300 BCE, 72 mud-brick houses used thermal mass, narrow shade streets and rooftop sleeping to survive. The film explains why 35 to 80cm walls delay heat by eight hours, how porous zir jars and white linen cooled by evaporation, and whether the north-facing malqaf windcatcher in Nebamun's tomb worked for ordinary houses.
