what to say when someone sneezes instead of bless you
Responses to sneezing In English-speaking countries, the common verbal response to another person's sneeze is "bless you", or, less commonly in the United States and Canada, "Gesundheit", the German word for health (and the response to sneezing in German-speaking countries). There are several proposed bless-you origins for use in the context of sneezing.
Photic sneeze reflex The photic sneeze reflex (also known as photoptarmosis, Autosomal Dominant Compelling Helio-Ophthalmic Outburst Syndrome (ACHOO)[1] and colloquially sun sneezing) is a condition that causes variable difficulty to control sneezing in response to numerous stimuli, such as looking at bright lights or periocular (surrounding the eyeball) injection. The condition affects 18-35% of the population in the United States,[2] but its exact mechanism of action is not well understood.[3]
