Igloo as a snowhouse
...Although igloos are usually associated with all Inuit, they were predominantly constructed by people ofCanada's Central Arctic and Greenland's Thulearea. ...Snow was used because the air pockets trapped in it make it an insulator. On the outside, temperatures may be as low as −45 °C (−49.0 °F), but on the inside the temperature may range from −7 °C (19 °F) to 16 °C (61 °F) when warmed by body heat alone.
That last sentence- an igloo gets as warm as 16 degrees when outside temperatures are as low as -45????
Aghhhhhh!!! We'd be better off living in a freaking igloo!!!
*Dear Mum, Dad, Matsumoto Child Welfare etc etc, please don't worry. Of course we turn the heaters on as soon as we get up. Within about 10 minutes we're out of the minus temperatures altogether- even 6 degrees feels positively balmy after that! But there is something satisfying about checking the thermometer and knowing that you're not just being a wimp- it really is freezing in here!
