Many residents rely on heated garages to keep their vehicles from freezing, and they often leave them running during the winter months.

Oymyakon has an extremely short growing season, limiting agricultural activities in the region.

Due to the cold climate, traditional Russian outhouses (outdoor toilets) are not feasible, so indoor plumbing is common.

Despite the extreme cold, some hardy crops like potatoes and carrots are grown during the short summer.

In the winter, the ground becomes too hard to dig graves, so bodies are often stored in a morgue until the ground thaws in the spring.

Oymyakon's residents adapt to the extreme conditions by wearing layers of clothing, fur-lined hats, and insulated boots.

The city has a small airport, which can be challenging to operate in such cold conditions.

Oymyakon's cold climate is a tourist attraction, with visitors coming to experience the extreme temperatures.

The city is sometimes referred to as "Stalin's Death Ring" because of the harsh conditions experienced by prisoners sent there during the Soviet era.

Oymyakon's extreme cold is a testament to human resilience and the ability to adapt to some of the harshest environments on Earth.
