Why people say ‘bless you’ when someone sneezes

The phrase “bless you” is almost reflexive in many cultures, uttered almost immediately after someone sneezes. But why do we say it? This tradition, steeped in history, superstition, and religion, reveals much about human nature and how our understanding of medicine has evolved over the centuries. This article explores the origins of this common saying, examining its historical context, cultural variations, and the science behind sneezing, providing a comprehensive look at a seemingly simple response.

The historical origins of saying ‘bless you’

Ancient roots

The practice of blessing someone who sneezes dates back to ancient times, with several theories explaining its origin. One of the oldest beliefs comes from ancient Rome, where sneezing was seen as a sign of wellness, prompting the expression “Jupiter preserve you” or “salve,” which means good health. However, as the plague ravaged Europe, Pope Gregory the Great suggested using the phrase “God bless you” as a protective prayer in response to the sneezing that often preceded illness.

Superstitions and beliefs

Across different cultures, sneezing has been associated with omens, spirits, and divine intervention. In some beliefs, sneezing was thought to expel demons or evil spirits from the body. Saying “bless you” was a way to ward off these spirits and protect the sneezer from further demonic attention. Alternatively, it was sometimes believed that the soul could momentarily leave the body during a sneeze, making the individual vulnerable to harm. A blessing, therefore, acted as a safeguard, keeping the soul securely within the body.

Cultural variations in the blessing

Across continents

The tradition of blessing a sneeze isn’t limited to any single culture or religion, although the expressions vary. In Arabic-speaking countries, the response is “Alhamdulillah,” meaning “Praise be to God.” Hindus might say “Live” or “Live well,” a straightforward expression wishing good health. Meanwhile, in East Asia, responses can be more secular, often just acknowledging the sneeze rather than blessing it, such as saying “健康” (health) in Chinese.

Modern interpretations

Today, the phrase “bless you” is often used more out of politeness rather than due to a literal belief in its protective powers. It’s a social custom that signifies politeness, concern, and sometimes, humor, depending on the context and relationship between the individuals involved.

The science behind sneezing

Why we sneeze

Sneezing is a reflex to clear the nasal passages of irritants like dust, pollen, or a viral infection. It’s a protective mechanism that helps to prevent potentially harmful particles from entering the lungs. The process involves the irritation of the mucous membranes of the nose or throat, triggering a forceful expulsion of air from the lungs through the nose and mouth.

Health implications

While sneezing is typically a benign, self-correcting occurrence, it can sometimes be a symptom of an underlying condition. Allergies, common colds, flu, and triggers like strong smells or changes in temperature can provoke sneezes. Regular or chronic sneezing might require medical attention to manage any underlying allergies or health issues.

The tradition of saying “bless you” when someone sneezes is a fascinating blend of history, culture and superstition. Despite the advancements in health care, the custom persists, highlighting a human tendency to cling to tradition and the comforting aspects of shared social practices. It not only reflects a universal concern for health and well-being but also serves as a reminder of our interconnectedness, even in the smallest of gestures. Whether rooted in superstition or simply habit, the reflex of blessing a sneeze shows the complexity and charm of human interactions, woven into the fabric of everyday life.
