The speed of sneezing in humans
The sneeze is very fast, with a speed of 100 miles per hour, in addition to that it sends 100,000 germs in the air with it. [1]
Causes of sneezing
Medically
Influenza and the common cold excite the mucous membranes in the nose , and thus sneezing occurs. As for allergies, it has the largest part of its causes, and a person’s sensitivity to dust, air, pollution, dampness, and mold resides. Four additional reasons fall under medicine as follows: [2]
- Hormonal rhinitis: It occurs in cases of physiological changes to the body, when the estrogen hormone rises during the menstrual cycle, pregnancy, or by receiving the estrogen hormone externally through the mouth to prevent pregnancy.
- Atrophic rhinitis: is an inflammation of the nose amyotrophic a rare disease, centered in the bacterial causes that lead to a lack of vitamin A, or vitamin D, or iron deficiency, plus it is suspected to be a shortage of the hormone estrogen.
- Occupational rhinitis: It is the most common and is triggered by dense cigarette smoke, cold air, air fresheners and other chemical irritants in the workplace.
- Acetylcholinesterase inhibition: This enzyme is found in the areas of nerve entrapment, where inhibition of it leads to the expansion of the duct in the mucous membrane, while the hormone progesterone causes congestion through the expansion of vessels.
- Light sensitivity: One in three people is exposed to light sensitivity, or the so-called photo sneeze, which is a genetic disease transmitted genetically from a parent to their children. [3]
Aging
Aging leads to atrophy of the submucosal glands in the elderly, and severe irritation of sensitive nerve endings, which leads to a hardening of the nose , and the production of thick and sticky mucus, which may cause sneezing. [2]
