It's Just That Cold
Igloos are made of compacted snow blocks, which have excellent insulating properties that help retain heat inside. The heat generated by the fire is trapped within the igloo, raising the temperature slightly but not enough to melt the snow. Additionally, the cold air outside helps maintain the igloo's structural integrity and prevents the fire from reaching a temperature high enough to melt the snow.
Igloos used to be winter homes for Canadian and Greenland Inuits (the people sometimes called Eskimos). Inuits as a culture don't live in igloos anymore - there's no garage for the snowmobile. Igloos are made with blocks of snow about 2 feet by 4 feet and 8 inches thick. The top edges of the blocks are rounded so the structure forms a dome at the top. An experienced builder can make an igloo in less than two hours. At the top of the igloo is a hole to allow ventilation. This is also a key reason why igloos don't melt. The hottest air and smoke rise up through the hole. In the middle of an igloo, a shallow saucer burns seal blubber for heat and light. A high wood fire might melt the structure. But this wide, low blaze and the inhabitants' body heat keep the igloo relatively warm - between 45 and 60 degrees, experts say. That's not bad, considering it can be 40 degrees below zero outside. The inside wall of the igloo blocks does melt, to some extent. But the outside air is so cold and the building blocks of snow so thick that the blocks continually refreeze.
Igloos are warm inside because the thick walls of ice and snow act as insulation, trapping the heat from the occupants' bodies and any heat sources inside the igloo. This insulation helps to maintain a relatively stable temperature inside, keeping it warmer than the frigid temperatures outside.
Inuit use convection currents inside igloos by positioning the entrance lower than the living area, allowing warm air to rise and cold air to sink. This creates a natural circulation of air that helps regulate the temperature inside the igloo, keeping it warm. Heat generated by occupants and cooking also contributes to maintaining a comfortable temperature.
Eskimo build igloos from compressed snow because it is a better insulator, trapping warm air inside and keeping cold air out. Ice is denser and conducts heat faster, making it less suitable for maintaining a comfortable temperature inside the igloo. Snow also provides better structural integrity when compacted properly.
Even though igloos are made up of ice, Eskimos stay warm because their body heat warms the air inside the igloos and the air inside becomes warmer than the air outside. Both air and ice are good insulators and they reduce heat loss from inside the igloos to the surroundings by conduction.

They melt.
no because people sleepn in them.
They melt.
ice is a bad conductor of heat. Any heat generated from inside the igloo, usually from body heat or a small fire, stays inside.
Not as long as the air temperature remains below freezing.
Eskimos stay in there igloos, their body heat warms u the air inside the igloos and the air inside becomes warmer than the air outside. Both air and ice are insulators and they reduce heat loss from inside the igloos to surrounding by conduction..
they are warm not hot or cold
food, warmth, and materials for inside their igloos.
Actually, igloos are ice structures and ice is an insulator. So, any heat(body heat or a small fire) from inside the igloo will be reflected back from the inner ice wall because ice is an insulator. The heat (Especially from a fire) does melt the inner wall of ice a little but the temperature outside the igloo is so cold that it refreezes the ice back. So, this insulation property of ice help the eskimos keep warm. You can check out the link for a more detailed explanation along with illustrations.
they live off of the animals, fire and their cozy and warm igloos
