Here’s the fun part. If it’s -40°F outside (the kind of cold that hurts your face), the inside of an igloo can stay around 32°F just from your body heat alone. That is the difference between freezing and surviving.
But add a small oil lamp or a little stove? Get ready to sweat. In fact, experienced builders say it can easily climb to 60°F (16°C) or more. That’s t-shirt weather, my friend.
A little story from the Arctic
I once read about an Inuit elder who visitors making a modern igloo. They lit a single seal oil lamp, and within minutes, the guide had to take off his parka. He was sitting there in a t-shirt, complaining it was too hot!
Imagine that: you’re inside a house made of snow, sweating, while the wind howls outside. It feels like a magic trick, but it’s just good science.
