"Don't put your fingers in your nose!"Among the frequently repeated commandments to children by their parents, that of not decreasing the nose is in the right place.It's like that, the little ones love to trifle it.But also part of the biggest.
Mickey, dumplings or even "skill" as we say among the ch’tis, no matter the name we give to our nasal production, too many are those who love rolling them between the fingers.But is it without risk of decreasing your nose?And besides, what is in a snake?It’s summer, so 20 minutes take the time to answer scientifico-permanent questions that we don’t always ask.
What are nose droppings made up?
Before drying in the form of droppings, nasal mucus is rather "aqueous and viscous.It is synthesized by the glands located in the nasal mucosa, they are fairly neighboring glands of the salivary and lacrimal glands, ”explains Dr. Nicolas Boulanger, ENT doctor.In case of colds, winter viral diseases or allergy, the production of mucus is racing and we turn into a factory in Morve."In the nasal mucosa, there are glands, which form small bags loaded with secretions, whose production is regulated by the nervous system, specifies the ENT.In the event of viral involvement, the virus will kill the cells, and goes, in a schematic way, to explode these small bags, so we have the flow which is blocked ".
And the droppings, is it the same thing in a dried version?" Not quite.They are composed of large particles present in the air that we breathe throughout the day, mixed with a little dried mucus ".
Otherwise, have you never noticed that what many call "morve" strangely resembles egg white?This is due to the composition of nasal mucus, a clever mixture of water and enzymes with antibacterial properties.And in particular the lysozyme, which is found in other secretions such as tears and saliva, but also in...egg white.Eureka!
What are they for ?
"The nose has a respiratory function and an olfactory function," says Dr. Boulanger.In their respiratory function, the nasal secretions have the role of moistening and reheating the air in order to prepare it for better pulmonary oxygenation.This is why if you do a sports session, the coach will say to you "inspire with your nose, exhale through your mouth".By breathing through the nose, the passage from oxygen to the lungs will be of better quality ".But nasal mucus has other properties."The surface of the nasal mucosa inside the nose is lined with eyelashes.These eyelashes "beat" and thus capture the foreign particles that we breathe, and will then degrade them.The mucosity flows on these eyelashes and form a "carpet", a layer of mucous membrane which will come to trap the particles of the air and make barrier to the penetration of viruses and bacteria: it is a filter ".
These particles are therefore trapped in our nasal mucus.Thus, those who live in urban areas will notice by blowing themselves that their production is sometimes stained with black.This is due, among other things, to the pollution particles present in the air.
How to clean them?
If you have the nose congestioned by an overflow of mucus or droppings, the easiest way remains to fly in a paper handkerchief, "not directly with your finger, insists the ENT.Otherwise, we risk depositing the bacteria that we have on the fingers, like golden staphylococci, for example ".If your "production" is really abundant or tough, we do as with babies: "We clean our nose with physiological duserum, which is the most compatible liquid, and not simply in clear water, prescribes Dr Boulanger.But people rather tend to use small pods or seawater -based sprays, which is not effective because it takes larger volumes.For a good nose washing, you have to use a syringe of at least 20 milliliters of physiological serum, which is caused by a nostril and flowing by the other ".
Nose droppings in numbers
Every day, an adult breathes on average 10.000 liters of air!To filter it, the nose manufactures daily between 1 and 2 liters of nasal mucus.We told you that the body was a real droppings factory!A large part of this production is transported to the throat by the eyelashes that line the nasal mucosa.In practice, it is swallowed and it is found in the stomach, which will atomize the microbes for which it is loaded.
And you, the droppings?
"I can't help but decrease my nose at home, at work, in the street, on the terrace, it's like an uncontrollable reflex, says Paul, thirty.I do not know how many times I do it, it is unconscious and aware at the same time, but if I was told that it is several dozen times a day, it would not surprise me!For the greatest disgusting of my wife, who gives me black looks when I decromat my nose in her presence.She says to me: "Stop! You're really a pork" "".A habit not very glam called rhinotillexomania (word account triple in scrabble!).
Unusual info:
You have seen (or you remember), children love to eat their nose droppings!Just like some indelicates that we find in transport, or in the red light, driving their car (we see you, gentlemen).Even Pope Francis, badly hidden behind a porthole, obviously does not resist the urge to eat a little Mickey.

These are mucophages, literally those who eat their mucus, or nose droppings.It is not uncommon, since one in 70 would eat their nose droppings.Well this gesture, which could be described as frankly disgusting, could prove to be good for health. Des travaux très sérieux, menés par le Pr Scott Napper, professeur de biochimie à l’université de Saskatchewan, au Canada, ont démontré le rôle protecteur sur le système immunitaire que jouent les crottes de nez ingérées."When mucus arrives in the intestines, it works as a vaccine that strengthens immunity," he explains.So, if you experience an irrepressible desire to decrease your nose and eat the fruit of this hunt, listen to yourself ”.
How it works ?We said it earlier, "The nose is a filter in which many bacteria are collected, confirms Professor Friedrich Bischinger, an Austrian lung specialist, who also studied the virtues of nasal mucus.Eating the droppings you remove from your nose is a great way to strengthen the body's immune system ”.But do not see it an invitation to mucophagy!
