Ever wondered how igloos keep people warm in extreme Arctic cold?
When a small fire is lit inside, it gently melts the inner snow layer.
The freezing temperatures outside instantly refreeze it, creating a hardened, airtight shell that locks in warmth.
This clever natural insulation can raise the inside temperature to around 60°F, even when it’s –50°F outside!
Ingenious shelters like these have protected Inuit and other Arctic peoples for centuries, showing just how brilliantly traditional knowledge adapts to nature’s harshest conditions.
