Why do we say 'bless you' after a sneeze?
culturehistory
Quick Answer
The custom is often linked to Pope Gregory I during a plague in 590 AD and to old beliefs that a sneeze put the soul at risk.
The Full Story
A popular story says Pope Gregory I ordered prayers after sneezes when a plague struck Rome in 590 AD, since sneezing could be an early sign of illness. Other traditions held that a sneeze could let the soul escape or let evil spirits in, so a quick blessing offered protection. Similar responses exist worldwide: Germans say 'Gesundheit', meaning 'health'. Today the phrase survives mostly as simple politeness.
