How Persians Survived 40°C Summers Without AC

How Persians Survived 40°C Summers Without AC In Yazd, one of the hottest cities on Earth, summer afternoons climb well past 40°C. In 1670 there was no electricity, no fan and no fridge. Yet families slept comfortably on their roofs and drank ice-cold sherbet in July, in the middle of the desert. How? We spend one full summer day with an ordinary family in Safavid-era Yazd, Persia, following them from the roof to the reservoir, down to the basement, up to the wind tower, into the courtyard and back to the roof. Their house cooled itself, and it did it for free.
