An Ancient Belief System
The custom of acknowledging a sneeze is ancient, with roots stretching back to at least ancient Greece and Rome. In these cultures, a sneeze was not just a bodily function; it was seen as a sign or an omen from the gods. Depending on the timing and circumstances,
a sneeze could be interpreted as either a good or bad omen. In Homer's "The Odyssey," for instance, Penelope takes her son's sneeze as a divine sign that her wishes for her husband's return will come true. One of the most persistent early beliefs was that a sneeze could expel the soul from the body. The phrase "bless you" was thought to act as a safeguard, preventing the devil or evil spirits from snatching the momentarily vulnerable soul. Conversely, some believed a sneeze opened the body to invasion by evil spirits, making a blessing a form of spiritual protection for both the sneezer and those nearby.
The Plague and a Papal Decree
Perhaps the most famous origin story for "bless you" dates to the 6th century, during the reign of Pope Gregory the Great. At the time, a devastating plague was sweeping through Europe, and one of its noticeable symptoms was intense sneezing. Believing a sneeze was a harbinger of almost certain death, Pope Gregory I is said to have decreed that Christians should respond with a blessing. Saying "God bless you" was essentially a short prayer, a plea for divine mercy and protection for someone who might be on the brink of succumbing to the deadly illness. This papal recommendation spread across Europe along with the plague, cementing the phrase's connection to health and mortality in the collective consciousness.
A Matter of the Heart
Another enduring, though physiologically incorrect, theory is that the heart momentarily stops beating during a sneeze. This belief led people to say "bless you" as a way of welcoming the person back to life or to ensure their heart would continue beating. While a forceful sneeze can temporarily change the pressure in your chest and affect blood flow, which may alter the rhythm of your heartbeat, it does not actually stop your heart. Nevertheless, the myth was widespread enough to contribute to the tradition of offering a blessing as a form of good luck and a wish for continued life.
Global Greetings and Good Health
The response to a sneeze isn't unique to English-speaking cultures. In Germany and many German-immigrant communities in the United States, it's common to hear "Gesundheit!", which literally translates to "health". This secular wish for good health became popular in the U.S. in the early 20th century. Many other languages echo this sentiment, with responses translating to wishes for health or a long life. For example, Spanish speakers might say "Salud," and in Ireland, you might hear the Gaelic "Sláinte," both meaning "health". Some cultures even have escalating responses for multiple sneezes.
From Superstition to Social Grace
While most of us today don't worry about our souls escaping or evil spirits invading when we sneeze, the habit of saying "bless you" persists. What began as a mixture of divine omen-reading, spiritual superstition, and a desperate plea during a deadly plague has evolved over centuries. In the modern era, saying "bless you" is largely considered a simple act of politeness. It's a way to acknowledge a small, involuntary disruption and extend a moment of goodwill. It functions as a social script, a reflexive and kind gesture that connects us, even if we've forgotten the dramatic and sometimes fearful reasons our ancestors first uttered the words.
