what results in sneezing?

Answer 1

Inhaling something like dust or pollen which irritates the mucus membranes in the sinus cavity or a histamine response.

Answer 2

Sneezing is a process through which the body removes irritants. People with allergies sneeze because they release irritant chemicals like histamine into the nose when they come into contact with allergens such as dust mite, animals or pollen. Sneezing due to pollen allergies usually occurs in spring and summer. However, you do not have to have allergies to sneeze. Almost anything that irritates the nose can trigger a sneezing fit, including dust, strong smells, temperature changes and infections.

A sneeze starts with the irritation of the lining of the nose, and ends in an explosion of air from the nose and mouth. Nerve impulses travel from the nose to the brain, then back to other nerves that control the muscle of the abdomen, chest, diaphragm, neck, face and eyelids as well as the mucus glands and blood vessels of the nose. That's why we usually end up closing our eyes when we sneeze. In people with allergies, histamine irritates nerve endings (triggering sneeze and itch), makes bloods vessels in the nose swell and leak fluid (blocked nose) and drives mucus glands to work harder which results in running nose. Hope this answers your question.

Answer 3

Well most would say Snot. But the act of sneezing I think is a natural way for the body to clean out any dust, pollen and bacteria out of the nose.
Achoo and God BLess.
