Why Do We Sneeze When We Are Exposed to Bright Light?

Sometimes, when you see something really bright, like the sun or a flash of light, your body might decide it's time to sneeze. This is called the photic sneeze reflex. It happens because light sends messages through a special nerve in your head that connects your eyes and nose. When the brain gets confused by all these signals, it tells your nose to clear out with a sneeze!
