"Bless You": Why a Sneeze Needed a Blessing

It is the only bodily reflex the whole room responds to with a blessing. Sneeze, and strangers say "bless you" (or Gesundheit, "health") — a courtesy so automatic that its strangeness goes unnoticed. Behind it sit some of superstition's oldest fears. One tradition held that the SOUL briefly left the body in a sneeze, so a blessing kept it from being snatched, or welcomed it back. Another, that the heart momentarily stopped (it doesn't) and needed God's help restarting. The most historically grounded: during the plague, a sneeze could be the first sign of fatal illness, and "God bless you" was a genuine prayer over the possibly doomed — Pope Gregory I is often credited with formalizing it in the 6th century. Layered on top are the count-omens: sneeze once for a wish, twice for a kiss, and the old rhyme running through the days ("sneeze on a Monday, sneeze for danger...").

What a sneeze is

The physiology is a violent, ordinary marvel: an explosive reflex clearing irritants from the nose, propelling air at remarkable speed, triggered by dust, pepper, allergies, infection — and, in about a quarter of people, by bright LIGHT (the photic sneeze reflex, a genuine inherited quirk). Nothing leaves the body but air and droplets; the heart keeps beating. The blessing survives on momentum and manners, a fossil of fears about souls and plague preserved in a two-word habit nobody questions.

Our archive keeps the coincidence file the count-omens live in: the reader who sneezed twice, thought "a kiss," and got one; the sneeze-on-a-Thursday that "meant something better coming," retold when it did; the person whose sneezes seemed to track a specific someone's thoughts. Dust explains the sneeze. The omen-rhyme's hits are what the jury weighs — over a tissue.
