• The Times, in other words
As the end of a particularly bad flu season approaches in many parts of the world, you’ve probably been hearing “achoo!” a lot.
But cultures respond to sneezes differently, and there’s little consensus on how some of those norms developed.
While it’s generally unnecessary in Japan and parts of China to comment, many countries use a version of “God bless you.”
The sneezer’s welfare is the main concern. Germans say “gesundheit” (health), while Turks say “cok yasa” (may you live long).
Sometimes the response is dictated by the number of sneezes. In parts of Latin America, the first sneeze is met with “health,” the second with “money” and the third with “love.” The Dutch wish you “health” for your first two sneezes before the third brings a “good weather tomorrow.”
Health-based wishes seem self-explanatory, but the origin of “God bless you” is uncertain.
The most popular theory is that Pope Gregory I started it by blessing a person with the plague. But it’s probably not true.
