Why do we sneeze?

<< < (2/6) > >>

Qing:
Thank you for helping me.[:D] I've been sneezing madly for nearly one week,[:(] and that's what causes me to think why people sneeze.
I don't seem to have got any cold or hay fever but sneeze.
Is it right that there are capillary networks on the very surface of lining inside the nose, and what's why sometimes when you blow your nose or even sneezing will cause some kind of bleeding?

cuso4:
Qing, are you allergic to anything? At this time of year, if you continue to sneeze you probably have hay fever, even if you don't want to admit it.

Angel

Quantumcat:
Yup, you're right about the bleeding.

Am I dead? Am I alive? I'm both!

nilmot:
Angel, I think the nose, eyes and tear thing Chris had already explained that on the 'Tears' topic.

Qing:
The only thing I know that I am allergic to is iodine, but that's only when I actually use it on my skin.[:(] However I do have some problems with my nose,e.g.rhinitis.
By the way,Angel,have you finished all your exams?

Qing
