This seems to be a very frequently asked question.  In its various forms, the following topic seem to be all discussing very much the same issue.

Why do we sneeze when we look at the sun?

I don't. However, my mother and my brother do need a source of light to sneeze.

I sneeze in bright light. Dr Karl on the ABC suggested it was due to neurons on unrelated circuits touching one another (cross-wiring in the vernacular). I don't worry about it.

It's called a "photic sneeze".

But what makes an orgasm trigger a sneezing fit?

[Translunary]

About 25% of people sneeze when they look at the sun or another bright light. Sun-sneezing has been called everything from photic sneeze reflex to ACHOO syndrome.
