Photic sneeze reflex

Photic sneeze reflex is when someone sneezes every time they are exposed to bright light. It happens because the nerves in the eyes get confused and send a signal to the nose to sneeze instead of just telling the brain that they saw something bright. It's like when you're playing with toys, and you accidentally pick up the wrong toy because they all look the same. Except instead of toys, it's nerves in the eyes, and instead of picking up the wrong toy, they tell your nose to sneeze.

It's not just in humans, some animals also have this reflex. For example, if you ever see a cat suddenly sneeze when they see sunlight, it could be because of the photic sneeze reflex. Some people have this reflex, but not everyone does. It's not really a big deal, just something interesting about our bodies that some people might have.
