At first glance, an igloo looks like the coldest shelter imaginable.
But step inside — and it can feel surprisingly warm, even when outside temperatures drop to –50°C (–58°F).
So how does a house made of snow and ice trap heat instead of losing it?
In this documentary-style video, we explore the brilliant natural engineering behind igloos — from snow’s hidden insulating power to the ice shell that forms when warmth melts and refreezes the walls. You’ll learn how Indigenous Arctic peoples perfected this design over generations, creating shelters that are strong, sustainable, and shockingly efficient.
This isn’t primitive survival — it’s smart design born from nature.
