Why Does Sneezing Feel Good - The purpose of sneezing is to remove irritants from the nasal cavity. This 2009 photo, taken during a sneeze, dramatically illustrates why a mask is necessary when someone coughs or sneezes, as droplets of saliva are ejected from this man's mouth in a large cone. . protecting others from germs.
Sneezing (also called sternutation) is the semiautonomous, vibrating expulsion of air from the lungs through the nose and mouth, usually as a result of foreign particles irritating the nasal mucosa. A sneeze forces air out of the mouth and nose in an explosive, spasmodic involuntary movement. This action allows the mucus to escape through the nasal cavity.
Why Does Sneezing Feel Good
Sneezing can be caused by exposure to sudden bright light, sudden temperature changes (drops), cold wind, stomach upset, allergies, or viral infection. Since sneezing spreads the disease through infectious aerosol droplets, it is recommended to cover the mouth and nose when sneezing with a forearm, inside of the elbow, a tissue or a handkerchief. In addition to covering the mouth, it is recommended to look down to divert the spreading droplets and avoid high concentrations at the person's breathing height.
Hold That Sneeze? Maybe Not
The function of sneezing is to expel mucus containing foreign particles or irritants and clear the nasal cavity. During a sneeze, the soft palate and palatine uvula descend, and the back of the tongue rises to partially cover the pharynx, forming a vturi (similar to a carburetor) according to Bernoulli's principle, which accelerates the air leaving the lungs. mouth and thus creates a low pressure point at the back of the nose. In this way, the air enters through the tip of the nose, and the mucus and pollutants come out of the mouth. Sneezing with your mouth closed expels mucus through the nose, but is not recommended because it creates too much pressure in the head and can be harmful.
Sneezing cannot occur during sleep due to REM atonia - a physical condition in which motor neurons are not activated and reflex signals are not transmitted to the brain. However, sufficient external stimuli can cause a person to wake up from sleep, but the subsequent sneezing occurs at least partially in the awake state.

Sneezing usually occurs when foreign particles or sufficient external stimuli pass through the nasal hairs to reach the nasal mucosa. This causes the release of histamines that stimulate nerve cells in the nose, which send signals to the brain to initiate sneezing via the trigeminal nerve network. The brain integrates this initial signal, activating the pharyngeal and tracheal muscles and causing a large opening of the nasal and oral cavity, resulting in a forceful expulsion of air and bioparticles. The forceful nature of a sneeze is explained by the fact that it involves multiple organs in the upper body—a reflex response that involves the muscles of the face, neck, and chest. Sneezing is also caused by sinus nerve stimulation caused by nasal congestion and allergies.
How To Stop Sneezing: 12 Natural Tips
Neuronal regions involved in the sneeze reflex are located in the brainstem along the ventromedial part of the trigeminal nucleus of the spinal cord and in the lateral pontine-medullary reticular formation near it. This region appears to control the epipharyngeal, internal pharyngeal, and respiratory muscles, and the combined activity of these muscles underlies spermatogenesis.
The sneeze reflex involves the contraction of various muscles and muscle groups in the body, usually the eyelids. However, the common suggestion that you cannot sneeze with your eyes is incorrect.
In addition to irritating foreign particles, allergies, or possible pain, sudden exposure to bright light is another stimulus—a condition known as the photic sneeze reflex (PSR). Exposure to sunlight from a dark building can cause PSR or ACHOO syndrome (autosomal dominant compulsive helio-ophthalmic infiltrates of glare).
Bright light sneezing is an autosomal dominant trait and affects 18-35% of the human population.
Sniffling, Sneezing, & Jaw Problems
A rare factor that some people experience is immediate fullness of the stomach after a large meal. This is called snatiation and is considered a medical disorder that is genetically transmitted as an autosomal dominant trait.
Although harmless to healthy people, sneezes spread disease through infectious aerosol droplets, which are usually 0.5 to 5 µm in size. A sneeze produces 40,000 droplets.
To reduce the chance of spreading an illness (such as the flu), hold the sneezed person's hand, elbow, mouth, and nose with a tissue or tissue. Using your hands for that purpose has become quite useless
This is considered inappropriate because it allows germs to spread through person-to-person contact (such as shaking hands) or from objects that are frequently touched (especially doorknobs).
Holding Sneezes Is Dangerous Know Why Info 01 Min
Specifically, the most notable distance traveled by a sneeze (or breath) was 0.6 meters (2.0 ft), and the maximum speed of a sneeze was 4.5 m/s (about 10 mph).
Prov methods to reduce sneezing can help reduce exposure to irritants, such as keeping pets out of the house to avoid animal dander; ensure quick and continuous cleaning of dirt and dust particles; replacement of filters of furnaces and air handling units; air purifiers and humidifiers; and stay away from industrial and agricultural areas. Tickling the roof of the mouth with the tongue stops sneezing.
Holding a sneeze, such as pinching the nose or inhaling, is not recommended because the air pressure puts undue stress on the lungs and airways.
One computer simulation shows that the air pressure during a sneeze causes an explosion of 39 kPa, which is about 24 times more than a normal sneeze.
The Record Of A Sneeze Day
In ancient Greece, sneezing was considered a prophetic sign of the gods. For example, in 401 BC, General Afianus Xophon gave a speech urging his soldiers to fight against the Persians. The warrior emphasized his conclusion with a sneeze. This sneeze made a good impression on the soldiers, who thought it was a good omen from God.
Another divine instance of sneezing for the Greeks is found in the story of Odysseus. Pelope, his waiting wife, hears that Odysseus may be alive and says that if he returns, she and her son will honor their lovers. At that moment, their son sneezes loudly, and Pelope laughs happily, convinced that this is a sign from the gods (Odysseus 17: 541-550). Perhaps this belief has persisted throughout the ages, so that today in some parts of Greece, if someone asserts something and the lysist immediately sneezes, the former responds with "bless you, I tell the truth" or "bless you and this." truth" ("γεια σου κι παράμα λέω", ya sou ki alithia leo, or "γεια σου και ναθ ya sou ke na ki i alithia). A similar practice was followed in India.
If a person makes an imprecise statement in Flemish, or if someone sneezes, one of the listers will say "Mae'n biesd", literally "He sneezed", as if to prove the truth. - usually self-possessed. It's an ironic nod to an old superstition, with no hint of doubt or obvious confirmation, but the comment is received with a smile, so there's no need to sneeze and apologize for the interruption.
In Europe, mainly at the beginning of the Middle Ages, it was believed that human life was actually connected with the breath - a belief reflected in the word "end" (originally meaning "exhalation"), with an additional meaning from "coming". a d” or “to die.” This association, along with the large volume of exhaled air during a sneeze, led people to believe that sneezing could easily lead to death.
Why Does Chocolate Make Me Sneeze?
Such a theory could explain the traditional cliché of "God bless you" in response to a sneeze, the origins of which are tirelessly obscure. For example, Sir Raymond Hry Payne Crawford, registrar of the Royal College of Physicists, in his 1909 book, The Last Days of Charles II, states that the controversial monarch was given a mixture by his medical staff when he was on his deathbed. Mary primrose and ammonia extract help with sneezing.
However, it is unclear whether this promotion of sneezing was done to hasten his death (as a coup) or as a last resort of treatment.
In some parts of East Asia, particularly Chinese culture, Korean culture, Japanese culture, and Vietnamese culture, sneezing for no apparent reason is often taken as a sign that someone is about to sneeze at the time.
