I know that sometimes when some people feel the need to sneeze they look at a light and this triggers a sneeze. I, too, find this helps. What doen't help, however, is when I walk out of somewhere dark or shaded into somewhere bright, whereupon I break into a violent sneezing fit. These fits usually contain around 5-7 sneezes although my record is 9. This causes great helarity amongst my friends and often to passers by. It has happened as long as I can remember and although it's never been a huge problem I just would like to know why.

Dear Elliot:

Sneezing is usually caused by a reflex due to nasal irritiation or irritation of the diaphragm.  What may be happening in your case, the strong light causes you to blink you eye lids very tightly while holding your breath.  This would cause a valsalva and may induce sneezing (diaphragm irritation form the valsalva).  This is only a theory.  Sorry I can't be more definitive.  You might want to try this procedure and see if you can reproduce it just by doing the things that you do when the sneezing starts.
