In most of the Nordics a significant portion of the population would easily die after around 12-24 hours of no power for large parts of the year. It's very goddamned cold up here.
Old and young children, especially those living in cities or apartments would be in real trouble if heating cut out. They might not own enough thick blankets, and do not have alternative ways of heating their home.
It's just so weird. Everyone has a blanket on their bed. If not that, a thick comforter type thing.
You can actually put on more than one shirt too. If it's super cold, you can put on more than one pair of pants. You can put on more than one pair of socks.
If you're strange and your bed doesn't have blankets, you can put clothes over your bed. Most people have 5 to 10 pairs of pants, and a dozen shirts, a few sweaters. Put those on when awake + your winter coat. Put those clothes on the bed when sleeping. Works like a charm.
“Most people are prepared” is a great situation. Regardless, we still see folks in vulnerable situations die when the power goes out in extreme heat or cold. The minority that aren’t or can’t be prepared are the ones that need these guides most.
Heat is typically a problem, you can only take off so many clothes.
Cold typically isn't when at home. That why I have this reaction. You can just put on more and more clothes. There are ways to keep warm. Most deaths from cold are outside, where there are no supplies.
