aivastuksia

Aivastuksia, often translated as "sneezes" in English, refers to the involuntary expulsion of air from the nose and mouth. This physiological reflex is a common bodily function triggered by irritation of the nasal mucous membranes. The irritation can be caused by a variety of stimuli, including dust, pollen, pet dander, strong odors, or even sudden exposure to bright light (known as the photic sneeze reflex).

The process of sneezing involves a deep inhalation followed by a forceful exhalation. This rapid expulsion of air is believed to help clear the nasal passages of irritants. While a sneeze itself is a natural defense mechanism, the sounds and droplets associated with it can contribute to the spread of airborne pathogens. Consequently, covering one's mouth and nose when sneezing is considered a social courtesy and an important public health measure to prevent the transmission of illnesses like colds and influenza. In some cultures, specific greetings or well wishes are offered after someone sneezes.
