An igloo is a type of shelter made from blocks of compressed snow. Traditionally built by the Inuit people in the Arctic regions, igloos are designed to keep warmth inside while protecting against harsh weather. The dome shape helps distribute the weight of the snow, making it sturdy and able to withstand strong winds. Inside an igloo, the temperature can be surprisingly warm, often reaching above freezing, thanks to the body heat of its occupants. The walls of the igloo act as insulation, trapping heat. This unique structure showcases the incredible adaptability of humans to extreme environments, demonstrating how creativity can lead to effective solutions.
