Why don't Inuit children freeze to death without clothes?

Because of the long-term polar environment, Inuit people are different from Asian yellow people. They are short and fat, with slender eyes, wide noses, curved noses, wide faces and thick subcutaneous fat.

Another important guarantee for Inuit to resist the cold is the high-protein and high-calorie food they eat every day. Their traditional diet is all meat: fish, seals, walruses and whales in the sea, reindeer, musk oxen, polar bears and some small animals on land.

The reason why they can live in the igloo all the year round is because a special kind of clothes, "anurak Gu", is impervious to wind and rain, and can sleep peacefully in the ice and snow with tens of degrees below zero.
