Sneezing when walking outside

You a ginger?

Not uncommon. It's called the photic sneeze reflex.

Happens pretty often to me, especially if I have been inside some sort of store for a period of time. I generally sneeze twice while walking to the vehicle.

I was just about to start a sneezing-related thread before I saw this one- I sneeze everytime I take a shot of whiskey, no other alcohol, just whiskey. Is this indicative of anything?

Little Dyslexic the Vth does that often.

Dear Google...

The photic sneeze reflex (also known as photoptarmosis, Autosomal Dominant Compelling Helio-Ophthalmic Outburst Syndrome (ACHOO)[1] and colloquially sun sneezing) is a condition of uncontrollable sneezing in response to numerous stimuli, such as looking at bright lights or periocular (surrounding the eyeball) injection. The condition affects 18-35% of the population, but its exact mechanism of action is not well understood

I have a co-worker that has a serious sneezing problem. She will literally sneeze 20 times a minute for half an hour. It's unbelievable and so annoying obviously. And of course it's a terrible high pitched squeal.

happens to me frequently

It's bright lights.

Next time you feel a sneeze coming on and it won't come out, look at the light on the ceiling or sun. Happens to me all the time.

Yeah, photic whatever that was mentioned above
