How did we come to say something courteous to someone after they’ve sneezed - sh.itjust.works

How/why did saying things like bless you or gesundheit start? And when?

I use the German word Gesundheit. It means health. I will offer it for most audible bodily functions, though, not just sneezes.

That’s funny.

I use it for all of those, but also if someone uses or words I don’t understand or if they bite their tongue or anything similar. I successfully managed to confuse a lot of people doing that and it brings me great joy.
