The question popped in my head as to how a breeze (let's say one from a ventilator or ACU) can cause irritation in certain respiratory systems (e.g. nose/throat).
I haven't really found a suitable explanation by Google-ing?, so I came here to ask you.
I'm not here for an explanation that I won't understand, I'm no medical/biological expert at all, I'm just an overly curious person.
A simple, to the point explanation would do the trick for me.
PS: Just in case you're wondering how/why this question popped into my head, it's because I forgot to turn the fan off in my room before going to sleep & now I've come down with an irritated nose & sore throat.
PPS: I would've added more tags but not enough rep yet and for some reason throat and respiratory-system aren't known tags yet.
