You might be thinking, “Okay, cool party trick, but I live in a house with central heating.” Fair point. But this knowledge is actually handy for everyday life.
First, it changes how you think about cold. If ice can keep you warm, then a little insulation goes a long way. That drafty window in your living room? A rolled-up towel at the bottom is basically your own mini-igloo trick.
Stay warm without cranking the thermostat
Second, it saves you money. If a few inches of snow can keep a human cozy at -40°, imagine what a good sweater and a rug can do in your own home. You can turn down the heat, wear a hoodie, and feel almost as snug as someone in an igloo.
Body heat is real power. Gather the family on the couch for movie night? That’s a whole crowd of little heaters. Throw a blanket over your lap? You’ve just made a personal igloo zone.
