Why Do People Sneeze When They’re Exposed to Sunlight?

Sometimes, when people are in the sun, they sneeze. It’s like a secret signal from their body that says, 'Hey, I need to get rid of this stuff!' This happens because sunlight triggers special sensors in the eyes called photoreceptors, which send messages to the brain, and then poof, a sneeze!
