Due to an irritation in the nasal passage, this is known as Pav's irritation.
Twice
It means that you can die from it... :(
No, it is not possible to sneeze underwater because the nasal reflex that triggers a sneeze requires air to pass through the nasal passages. If someone tried to sneeze underwater, the reflex would likely be suppressed.
No, people can not sneeze out water and oil.
The same way people today sneeze.
All people sneeze. It doesn't vary by culture.
I think that people sneeze quietly because they want to be polite to people and they don't want no one else to hear their sneeze
When you sneeze a second time it usually means that whatever is irritating your nose is still in it after the first sneeze so your body continues to try to get it out.A 2nd, lighter answer: Sneeze twice, wipe once; the more you wipe, the less you scrape.
Yes, people do sneeze everyday but not typically everyone in the world.
Yes, they sneeze for the same reasons people do.
People sneeze mostly through their mouths.
Some people only sneeze once. Like me but my sneeze is a scream. I sneeze from my throat so that is probably why I only sneeze once. When you sneeze it is normally because your nasal passages are filled with mucus and your body is trying to remove it. When you sneeze multiple times it is just a reaction. Have you noticed if someone tickles your nose or you look at the sun you sneeze? After one sneeze some people have that tickle feeling so they sneeze repeatedly.
