Understanding the Context

A sneeze (also known as sternutation) is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. When you sneeze, it removes irritants like dirt, dust and pollen from your nose or throat. It’s your body’s way of getting rid of things that can make you sick or cause inflammation. A sneeze happens when something like mucus, a tiny object, or an allergen interacts with skin or the tiny hairs that line your nose.
