　　It is no wonder the village is the coldest permanently inhabited (有人居住的) settlement in the world with the average temperature for January standing at －50℃. Known as the "Pole of Cold"， the coldest ever temperature recorded in Oymyakon was －71.2℃. This is the lowest recorded temperature for any permanently inhabited location on Earth and the lowest temperature recorded in the Northern Hemisphere. Surprisingly, Oymyakon actually means "non­freezing water" due to a nearby hot spring.

　　Nothing grows there so people eat reindeer meat and horse meat. A single shop provides the town's bare necessities and the locals work as reindeer­breeders, hunters and ice­fisherman.
