I live in Romania and since I was a kid, I heard people talking about something we call, here in Romania, current—basically, the air flow which is being formed if at least two exterior windows are opened (or a window and a door, or two doors etc). I'm not sure how this term is being translated in other languages... I tried searching it in English, but I didn't find any information.
They say that, for instance, two windows in a room (both of them communicating with the outside world) are opened, the wind or air flow which is formed is terrible for your health—such as: you will get cold, you will get headaches, ear aches etc. Another case is when you travel by car and at least two windows are opened. And so on.
Like I mentioned, Romanians see this as a health risk. Some friends living in other countries (e.g. United States) and some people on internet forums say this is the concept which exists only in Romania.
How true is this affirmation? Perhaps, it's not only in Romania, however, how popular is this?
Apart that some friends who traveled in other countries said it, some people and posts on the internet claimed it too:
This post claims that the doctors don't take it in consideration. Later it mentions that not the air flow itself causes some unwanted problems, but some other factors related to it
Here somebody says:
Only Romanians feel it
And somebody replies saying Exactly!
