why do we sneeze when we see bright light?
In: Biology
It’s not totally understood but basically it’s thought that the nerves that connect your eye’s iris are also connected to the thing that makes you sneeze. When you see bright lights and your iris contracts, it also triggers the sneeze. https://en.wikipedia.org/wiki/Photic_sneeze_reflex
Fwiw, I call them “solar sneezes” and it happens to about 1/4 to 1/3rd of the population.
