The Sun is Nothing to Sneeze at…or is it?

Have you ever stepped out of a dark movie theatre into the bright sunlight and felt the urge to sneeze? If so, you probably have a harmless and not all that uncommon disorder known as Photic Sneeze Reflex.

This condition is characterized by the uncontrollable impulse to sneeze provoked by a transition from dark environment to an intensely bright surrounding, usually sunlight.
Also referred to as the “Achoo Syndrome”, this involuntary reflex is a genetic trait that affects both males and females alike. It is estimated that anywhere from 15 – 35 percent of the population has this disorder.

Those who have the photic sneeze reflex usually sneeze two to three times (although in rare case, some can sneeze up to 40 times) when transitioning from dark to bright environments, and while there are no associated health risks, there are concerns that this condition can be dangerous for people in certain professions, such as airline pilots.

While no one really knows why this reflex occurs, there are multiple theories that suggest that certain optic nerves are too close to other nerves that may trigger a reaction in the brain of photic sneezers or simply that those with this condition have a more sensitive visual system.

Regardless of the reason, the next time you exit a movie theatre on a bright sunny day, take notice of how many people exiting start sneezing, you might be surprised.
