Several reasons could be facts and were believed back in the days. The phrase stayed with us.
they say bless you because when you sneeze your heart stops's there thanking god that you did not die
I do
In Portuguese, you can say "saúde" which means health or "Deus te abençoe" which means God bless you in response to a sneeze.
God bless you = Gott segne dich (God) bless you! (after a sneeze) = Gesundheit!
Snot comes out of your nose and people usually say "bless you" or "god bless you". the reason people say god bless you is because you heart stops for a quick second and bacteria is what comes out when you sneeze.
God is not human and there are no physical needs in the supernatural realm. Therefore, God does not sneeze.
God can't sneeze, for he cannot be sick. He's perfect. If God were to choose to sneeze (sneezing is not always a symptom of an illness) and you were on hand to witness it, it would not be inappropriate to say "You bless You" which is a short way of saying "May you bless yourself".
No one really knows..... maybe people are just use to it. It was once believed that sneezing was something to do with being possessed by demons, so 'bless you' i.e.'God bless you', would help save you.
Bless you.
people used to think that if you sneezed you sneezed out your soul and they say bless you so the devil wont get it.
The phrase "God bless you" came from a belief that a sneeze could leave the body vulnerable to evil spirits or that the heart would momentarily stop during a sneeze. Saying "God bless you" was a way to protect the sneezer.
You just say bless you.
