Sometimes when you're in the sun, your nose suddenly feels like it wants to sneeze. It's all because of a special kind of light called ultraviolet (UV) light from the sun. This light can make some tiny particles inside your body move around, and that causes your nose to send out a sneeze, just like when you see something really bright or dusty.
Examples
- A child runs outside on a sunny day and sneezes three times in a row.
- An old man walking into the bright sunlight at noon suddenly begins to sneeze like he's been told to.
- A person wearing sunglasses on a cloudy day still sneezes when they take them off.
