The photic sneeze reflex, a condition where people sneeze when exposed to bright light, such as sunlight, is believed to be genetically inherited. If one of your parents sneezes in sunlight, there’s about a 50% chance that you will too. This quirky trait, sometimes referred to as “ACHOO Syndrome,” is harmless but highlights how certain reflexes can be passed down through family genetics. While not everyone has it, if your mother has this reflex, there’s a good chance you might inherit it as well.
