I haven’t heard of it, but I guess it makes sense. Like, it’s not uncommon in the US to drink hot coffee in the morning when it’s cold out if you’re camping or in an outdoors environment that’s hard to heat up. Delivers a big slug of heat directly to someone. But there’s no real reason that it has to contain caffeine.
I don’t know about Korea or other places, but Japan traditionally didn’t go in for house insulation, aimed to use the kotatsu rather than heating the living space as a whole.
I love that kotatsu idea! That would be such a cozy way to rest in on a cold weekend. This should be a thing everywhere …. But only the electric version. I’m not sticking my feet under a mystery blanket with a charcoal burner somewhere
