Yeah, what the hell is this video subject. I honestly thought this stuff was common sense.

Should be but search for “kwh per hour” and there’s plenty of people who seem confused by it all.

The one that I think more people misunderstand is temperature Vs heat Vs something feeling hot/cold. One is a property, one is energy, and the other is the transfer of energy.

You know a nation of people who may not be able to articulate their understanding, but definitely have a high intuitive understanding of that?
We Finns.
100C sauna and no problem sitting on wood, but happen to touch something metal and oooh-weee.
Also same thing happens the others way around when it’s - 20c outside. I don’t think there’s many people in Finland who don’t have a core memory of what cold metal tastes like in winter, because of the resulting trauma. And it doesn’t even need to be metal to stick.
Nicely explained.

100C sauna???
Dasus@lemmy.world 1 week ago
It’s perfectly commonplace to have at least a 100 degree sauna.
I think something like 140 is around the hottest I’ve been in.
The air is that temperature, but there’s also a ton of moisture in the air. You can take it for a few minutes at a time, then optimally you go take a dip off a pier into a lake or the sea. When I was in that 140c sauna it was a proper wood heated large sauna at my confirmation camp, it was on an island in the Baltic so we could run out the sauna and jump into the Baltic Sea. It wasn’t warm at all, but the intense heat of the sauna having warmed all the top tissues and muscles, you get a sort of immunity to the cold. Which lasts for a little while, and when you start getting cold enough, you go back to the sauna, and because the cool water has now cooled the skin and muscles, you get a resistance to the heat for a while.
Rinse and repeat. Literally.
This cycle supposedly has benefits for circulation and muscles.
And having done it ton in my life I don’t doubt that at all.
Usually I have to settle for the sauna in my apartment though. (I live in a cheap rental but a sauna is default in pretty much all buildings built after the 90’s.) And then either going to balcony to cool off a while or take cool shower. It’s not as nice, but it’s more or less the same.
Although I don’t rip the most out of my electric stove to get the most heat. I have it set on pretty low and I just use a lot of löyly. Probably I’d say my normal saunas are maybe around 90-110 degrees at the most. A sauna below 80 degrees is considered a “Swedish sauna”, which is to say we mock them as not being strong and manly as us and so Swedes would be afraid of having a “proper” sauna.
And to be honest the Swedes are pretty on board with this whole stereotype I guess, seeing us as brutes or something. Here’s a cool Swedish commercial featuring a Finnish man. They made it.
