#15: Achoo Alert!
There are tricks people use to induce sneezes, like looking at a bright light. But did you know some individuals are sun sneezers? For them, looking at the sun or bright lights triggers an uncontrollable sneeze reflex called the photic sneeze reflex or ACHOO syndrome. This phenomenon, thought to be inherited, involves crossed signals in the brain between the optic nerve and the trigeminal nerve. It’s a fascinating example of how our bodies can react uniquely to external stimuli. So, if you see someone sneeze in the sunlight, they might just be one of these intriguing sun sneezers!
These individuals are officially recognized as having a photic sneeze reflex, which causes them to involuntarily sneeze when they look at the sun or other bright lights. Surprisingly, this condition affects between 18 to 35% of the population. It’s more commonly observed in women and is believed to have a genetic basis. Who would have thought such a seemingly unique reaction to sunlight could be quite common and hereditary?
