Sneezing
Sneezing can also be a symptom of viral infections such as the flu and the common cold. More than 200 different viruses can cause the common cold. Sneezing, stuffiness, or a runny nose might be caused by anything that aggravates or irritates the nose—infections, such as the ones that cause colds and the flu. Of course, other irritants can also be a factor.
This behavior is normal because the body sneezes to empty the nasal passages. In addition, the nose may itch or tickle when foreign substances like dust, pollen, smoke, or dirt enter the nostrils. As a result, the body sneezes to accomplish the task of clearing the nose. In addition, sneezing is one of the body’s first lines of defense against invasive bacteria and pests.
The air people breathe is cleaned by the nose as part of its function to keep it germ- and dirt-free. Most of the time, mucus in the nose traps this dust and bacteria. The stomach subsequently digests the mucus, destroying any potentially hazardous intruders.
However, dirt and debris occasionally get inside the nose and irritate the throat’s and nose’s delicate mucous membranes. People sneeze as a result of the irritation of these membranes.
