Achoo! Sneezing is universal: annoying and satisfying, funny and embarrassing, noisy and sometimes snotty. But do you know why we sneeze? As you’ve probably guessed, there’s a sensible biological reason for it.

Here, we’ll answer your pressing questions on sneezing, from “what does sneezing do?” to “why do we close our eyes when we sneeze?” You’ve come to the right place to find out the details.

Why do we sneeze? Causes and mechanism

The physical process that triggers sneezing happens when the nerves in our sinuses are stimulated, this tells the body to expel air through our noses forcefully to clear them. These sinus nerves kick into action when we have allergies, nasal congestion or foreign particles like dust tickle the backs of our noses. As a protective mechanism, these nerves tell the body to expel air through our noses forcefully to clear them.

But why do we close our eyes when we sneeze? The whole process of sneezing takes some force from our bodies, and lots of muscle groups get involved, including ones in our face. This is why sneezing causes our eyes to close: it’s an involuntary response from our muscles.

Why do we sneeze when we have a cold?

It’s not just allergens or dust that make us sneeze – sneezing is also a common symptom of the common cold. But exactly why do we sneeze when we have a cold? When a cold virus infects nasal cells, our bodies react by releasing inflammatory mediators. These cause the nasal irritation that leads to sneezing.
