How do people live in igloos (houses made of snow)?

People live in igloos by utilizing the insulating properties of snow, which helps maintain warmth inside despite freezing temperatures outside. The structure is typically dome-shaped, allowing warm air from body heat to rise and circulate. Inside, they can create a small fire or use lanterns for light and additional warmth, and they often sleep on raised platforms to avoid direct contact with the cold ground. While traditionally associated with Inuit culture, igloos serve as temporary shelters rather than permanent homes.
