Why do you sneeze when you look at the light?

Steph, who laughs at me for saying “tree trees”, taught me this one – when you feel a sneeze coming but for some reason can’t get it out, look at the light and you will sneeze.

I didn’t believe her. I thought, “What a weird American old wives’ tale!”, but I tried it anyway (since she was my friend and all). It worked like magic. I have never looked back since.

It only struck me today the reason why you should sneeze when you look at the light. I think it has something to do with you pupil contracting in reaction to the light. Somehow, that tiny movement in the radial muscles of your eye triggers something off and preps your muscles to contract quickly for the sneeze. So you sneeze.

N.B. I don’t believe I turned on my computer and dialled up my pathetically slow internet connection just to write this down. I swear this must be an eureka moment.

ahaha... i know a dear friend who does that too... still disbelieving tho... are you sure it's the light and not the tilting of the head so that the mucus trickles in a different direction in your nasal cavity, triggering the sneeze? that's my theory btw... heh heh...

Interestingly, your theory is more widespread online than mine.
