Why Do We Sneeze in Bright Light?

Sometimes when you’re in the sunlight, you sneeze, and it feels like your nose is telling you to escape! This happens because a special nerve in your face gets excited by bright light. It sends a message to your brain: Sneeze now! It’s kind of like your body is saying, ‘Hey, I need to get rid of that stuff in my nose right now!’ And just like that, achoo!

Why Does This Happen?

Bright light hits the nerve in your face called the trigeminal nerve. It sends a signal to your brain, which tells you to sneeze. Some people are more sensitive to this than others, so not everyone sneezes when they see bright light, but for some, it’s like a sneeze alarm!
