you should check out howstuffworks, they explain everything there even such as silly question as sneezing.

Ugh… HowStuffWorks didn’t really explain much of anything at all (at least based on the first few articles that turned up on a search for “sneeze”).

Wikipedia, on the other hand, had all kinds of interesting things to say, like:

Sneezing typically occurs when foreign particles or sufficient external stimulants pass through the nasal hairs to reach the nasal mucosa. This triggers the release of histamines, which irritate the nerve cells in the nose, resulting in signals being sent to the brain to initiate the sneeze through the trigeminal nerve network. The brain then relates this initial signal, activates the pharyngeal and tracheal muscles and creates a large opening of the nasal cavity, resulting in a powerful release of air and bioparticles. The reason behind the particularly powerful nature of a sneeze is attributed to its involvement of not simply the nose and mouth, but numerous organs of the upper body – it is a reflectory response that involves the muscles of the face, throat, and chest.

(The italicized text is to explain “what’s going on” and the bold text explains why your nose tingles.)

So why does we sneeze more often when we’re sick?

@ deaddolly people say “God bless you” because the early Puritians thought you were expelling demons from your body. It just caught on from there.

@deaddolly Your heart absolutely does not stop at all when you sneeze. That’s a old wives tale that has long been disproved

“God bless you” also came from the days of the plague. Sneezing or a fever was a sign of the plague so when you sneezed people said bless you because they new only god could save you from the plague. (or modern medicine)
