That is because of how some people's nerves are routed. For some, the optic nerves are very close to the vagus nerve and may even share the same nerve sheath. The vagus nerve is what controls the heart, lungs, diaphragm, part of the vocal folds, and digestive tract. A sneeze is a spasm of the diaphragm. So when a very strong stimuli passes through the optic nerve, some crosstalk may occur and stimulate the vagus nerve, causing a spasm of the diaphragm and the sudden expulsion of air through the lungs and out the mouth. So if the mouth or lungs have anything in them at the time, it comes out along with the air, and thus saliva and possibly phlegm go everywhere.

Why do you sneeze when walking into the sun?
i have no idea. I think it's genetic because my grandfather and I both sneeze when we look at bright lights. Its not jus the sunlight, it's any bright light.

Why do some people sneeze when they walk into bight sunlight?
Some people sneeze in bright sunlight due to a reflex known as the photic sneeze reflex. This occurs when bright light stimulates the optic nerve, which can inadvertently trigger the sneeze reflex in some individuals. It's thought to be a genetic trait, affecting an estimated 10-35% of the population. The exact mechanism is not fully understood, but it demonstrates how our sensory systems can be interconnected.
Why does bright light cause some people to sneeze?
I am not a doctor nor any kind of researcher. Just someone who sneezes when I walk out into the sun. My idea is that when we are exposed to the bright light, we squint our eyes. When this happens it restricts our sinuses. A natural way of clearing our sinuses is a sneeze.
Is it true that you sneeze when you walk out of a dark room?
Yes, some people may sneeze when walking out of a dark room into bright light, a phenomenon known as "photic sneeze reflex." This reflex occurs in a small percentage of the population and is thought to be caused by the overstimulation of the optic nerve, which can inadvertently trigger the sneeze response. However, not everyone experiences this reaction, and it is not directly related to sneezing in general.
