For my country (Germany): Catching a draft. Basically people believe that a light breeze from an open window will make you ill.
Also Russia and probably most eastern European countries. One of my kids will catch a cold and the first thing my mother or grandmother will ask is if they were somewhere drafty.
We have a similar one here in the US. People think if you go outside when it’s too cold, you’ll get sick.
It’s not completely baseless. You can’t get sick from the cold itself, but lower core body temp does weaken your immune system until you warm up, making it easier for you to get sick if you do get exposed to something.
God, on one hand, catching a draft makes you die and then on the other STOSSLÜFTEN!!
Schon, wenn meine Mutter lüftet. Alle Fenster im Haus (auch im Winter) und das ist nicht mehr ein Zug, aber ein ganzer Hauptbahnhof lol
Yeah, but then they go and open all the windows to “change the air” no matter the weather.
I used to work with a bunch of Germans in the US. I came in to the office one time at about 4:30am in February. One of the guys had all the windows open when the outdoor temperature was something like -20F.
Like Moritz, I think that avoiding the draft is more important than changing the air at that point. 🙄
I also had an old manufacturing guy tell me that drinking cold water in the summer would kill you because of the shock to your system.
