sneeze -
To expel air as if the nose were irritated.
Wikipedia
A sneeze (or 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. Sneezing can be triggered through sudden exposure to bright light, a particularly full stomach, or viral infection, and can lead to the spread of disease.
