Can you stay warm in an igloo?

You can. The Eskimo igloo is a temporary home used on hunting trips. It is built by cutting large blocks of hard packed snow and placing them one on top of another to form a dome shaped house. Fur rugs are spread on the floor. Light and warmth come from a small lamp that burns seal oil.

An igloo floor is never just flat like the inside of a tent. It’s cut into terraces which create an upper level for sleeping, a middle level for the fire and a lower level used as a cold sink. Heavy cold air, which naturally falls, collects on the floor – ideally near the door – and stays there. And warm air, which is lighter and naturally rises, stays in the parts of the igloo people use the most, including the area they sleep in.

Because the door of an igloo is at the bottom of the structure and features at least one right angled piece of tunnel to crawl through, the powerful, freezing cold Lapland winds can’t blow directly into the living space. And the little hole cut into the top of the curved roof lets smoke from the fire escape safely.

All this means it can be as cold as minus fifty degrees Fahrenheit outdoors but as cosy as 19 to 61 degrees Fahrenheit indoors, not always warm enough for a T shirt but a temperature difference that’ll feel really good all the same, sometimes as much as seventy degrees warmer than the outdoors.
