Myth: Sneezing means a cold is coming on
While many of us assume that fits of sneezing mean a cold is coming on, it’s not entirely true. Sometimes sneezing is a signal that we’re starting to get sick, says Dr. Mirwaldt, but it’s not always the case. People sneeze for all sorts of other reasons—exposure to allergens, such as animal dander and dust, for example. Even something as simple as bright sunlight will make some of us sneeze, while others fall into fits of snorts after a big meal. So don’t panic if your nose starts to tickle.
