How Vikings Survived -40°C Winters Without Modern Heating

Imagine surviving -40°C winters with no electricity, radiators, or modern heating. Vikings built compact longhouses with thick walls that slowed precious heat loss. A central hearth provided heat, light, and a place to cook. Outside, layered wool clothing trapped insulating air around their bodies. Fire, insulation, clothing, stored food, and shared warmth worked together. They didn't defeat winter. They engineered their lives to survive it. #vikings #survive #history
