Why Do Some People ‘Sneeze’ in the Sun?

Some people sneeze in the sun because their bodies react to light. When sunlight hits their eyes, it sends a message through the nose, and poof!, a sneeze happens! This is called the photic sneeze reflex. It's like your body has a little switch that turns on when you see bright lights.
