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!
Examples
- Walking outside on a sunny day and suddenly sneezing like you've been hit by a dust storm.
- Trying to read under a lamp at night and sneezing without any reason.
