Airy

Regie

Guys can somebody tell me why my falseto all of a sudden became airy?
It wasn't like this last week but I dont know what is happening
My lower voice is not cracky and it didn't change a bit but my falseto register change

Here's my health condition now
Cold and coughing ( I know this is a bit dumb question but does this affect my voice?)

If you have been coughing, that can make your vocal cords swell. When your cords swell, you get poor cord closure. Poor cord closure makes your voice airy. This will be most apparent in your head voice.
