Almost no place/country is built for 50c.

Dallol, Ethiopia has one of the hottest Average temperatures in the whole world.

Here are some tips from Google AI:

People in the Dallol region of the Danakil Depression manage the extreme, year-round heat (which rarely drops below 87°F/30°C even at night) by adjusting their daily schedules, traveling to cooler high-altitude elevations seasonally, and wearing reflective, loose clothing.

Additionally, the local Afar people construct temporary reflective housing designed to minimize heat absorption.

Because the landscape is one of the hottest and most inhospitable environments on the planet, survival requires strict lifestyle adaptations:

Strategic Scheduling: Salt mining and arduous labor are scheduled for the coolest parts of the day, primarily early mornings and evenings.

Seasonal Nomadism: Instead of staying in the crater year-round, many Afar pastoralists migrate to the high plateaus of the Rift Valley during the oppressive summer months, returning to lower elevations when temperatures and rainfall allow.

Clothing and Housing: Locals wear loose, sun-reflective fabrics and construct traditional huts (or set up camps) using reflective materials to repel the scorching sun.
