Question

Why does looking up at the sun make you sneeze?

Answer 1

It's called the "Photic sneeze reflex" and it's not present in everyone. I personally don't sneeze *just* because of sunlight, but I do know that if I feel a sneeze coming on and I want to trigger it, looking at bright lights helps trigger the sneeze.

Answer 2

you are funny lol you should ask the question "does you sneeze whenever you look at sun?" let me answer that question I make okay lol I don't sneeze whenever I look at the sun I observe also other people and my dog lol none of them usually sneeze when they look at the sun. I think you usually sneeze when you look at the sun maybe you have some ill beliefe about looking at the sun - maybe it is just all psychological - what do you think?
