That’s why the Igloo will not melt.

The homes of the people living in Arctic regions do not melt for various reasons; first of all the polar wind: slamming on the walls of the igloos at a much lower temperature of 0 degrees, thereby allowing the external walls to remain always very cold, thereby preventing Igloo dissolution. When there is a fire inside, even if the air is hot, reaches the walls of the igloo, the ice resists, thanks to its thermal capacity, which is much higher than that of air, in fact, the ice needs much heat before beginning to reach the melting temperature.
These classic Eskimos housing, have a very limited internal space, which allows to heat up, with the sole presence of two persons, another reason that must be considered for the fact that never dissolve is that these homes are mainly used until the beginning of summer, and most of the time as a temporary home.
