Have you ever heard of the most inadvertent way of making yourself ugly?
I have, breathe with my mouth. Since I heard this statement, I am scared that the time to eat is now shortened. After all, when I eat, my mouth is constantly breathing, and I care about beauty.
Don't talk about me, I believe many parents often tell children like this: try not to breathe with the mouth, otherwise it will become ugly when you grow up. This statement is not only widely circulated on the Internet, it is also generally recognized by everyone, and even many professional doctors agree.
So, is this seemingly indisputable "fact" really right?
They breathe with their mouths, which has become ugly.
is a beauty killer for mouth breathing. The most common saying is that mouth breathing will cause a glandular face [1]. Although the term is rarely mentioned in the scientific community now, it has not affected everyone's fear of this term. The so-called gland-like face of is also called long face syndrome. Its typical facial features are: head extension, chin retraction, protruding upper teeth, irregular teeth, long face, etc. . Z1z
once convinced everyone of this statement, mainly from two cases [2].
The first one is that , a boy who was originally very handsome and handsome because of long mouth breathing, gradually decreased his appearance after he grew up, and finally developed a glandular face .

The leftmost picture above is a photo taken when the boy was 10 years old. It can be seen that the boy has a well-rounded appearance and features The proportions are also very coordinated, and even the contour of the jaw line is perfect. Even according to the current aesthetics, it is a proper little handsome guy. The turning point of
happened when the boy was 14 years old. It was the boy’s birthday that day. A friend gave him a gerbil as a gift. It was a very happy thing. Unexpectedly, the boy might be allergic to gerbils and his nose started to block. , The ventilation is getting more and more difficult. In desperation, the boy switched to mouth breathing .
Three years later, the boy's appearance has undergone tremendous changes . The two photos on the right are photos taken when the boy was 17 years old. Comparing the photo on the left, the boy's face has changed to a large extent-the face has become narrower and longer, the chin is retracted, and there is a double chin. The picture
later became almost typical of thousands of children who breathe through their mouths. In another case of
, comes from a pair of twin sisters, .

Sister Kelly and sister Samantha both have the habit of mouth breathing since they were young. However, the younger sister has undergone corrective treatment, but the older sister has not. As a result, when they grow up, the appearance of the two is not only worlds different, but also visible to the naked eye. The change.
is exactly these two examples of iron clank, making the public start to worry and even believe that breathing with the mouth will really cause a glandular face, which will become ugly . Many people have heard of this statement, worrying about the decline in their appearance, and have even bought mouth breathing correction stickers online to correct them secretly.
So, things are really as people worry and believe, will mouth breathing cause glandular faces?
Does mouth breathing become ugly?
Regarding this question, it is actually difficult to answer with a simple "yes" or "no", so we might as well find the answer from some scientific research.
In 1981, the scientist Harvold conducted experiments on rhesus monkeys in order to explore whether mouth breathing can cause changes in facial morphology [3].
Harvold found 42 rhesus monkeys. At the beginning, they were grouped according to their gender and appearance similarity, two in each group, a total of 21 groups. Subsequently, the researchers set one monkey in each group as the experimental subject, blocked its nostrils and forced it to breathe through the mouth, and the other did not make any changes.

zDuring the 0z experiment, the researchers recorded the appearance and characteristics of the monkeys every 3 months, and reopened the nostrils of the subjects every 6 months. The recorded appearance features include head X-ray measurement, photos of face and dentition, arrangement of dentition, and weight .One year later, the researchers found that the appearance of the monkeys who did not make any changes at basically did not change, but the monkeys whose nostrils were blocked have undergone great changes . Because the nostrils are blocked, they can only breathe with their mouths for a long time. As a result, a "dent" appears on the upper lip of their , and the bite of their teeth is also misaligned . When the monkey's nostrils were reopened, the monkey's lips gradually returned to their previous appearance, only the teeth did not return to their original shape.
However, after further analysis, they discovered an interesting phenomenon: there is no uniform change in the teeth problems of monkeys. That is to say, the teeth problems of different monkeys in are always various, and there is no uniform gland-like face as everyone suspects. Results like
can't help but make some people guess that mouth breathing may not necessarily lead to glandular facial features.
But this is just a monkey experiment after all, and it may be a bit unreasonable to be equal to humans.
In 2007, the Brazilian Journal of Otorhinolaryngology published an article titled "Study on the Relationship between Mouth Respiration and Facial Morphology Patterns" [4]. This time the research object is human.
researchers conducted observational studies on 119 adolescents aged 15-18. Among them, 50 teenagers breathed through their mouths and 69 teenagers breathed through their noses.

The results found that whether it is mouth breathing or nasal breathing, has a medium-width face that is the most common face shape in the two groups, and there is no statistical difference in facial shape between the mouth breathing group and the nasal breathing group. In addition, there is no connection between mouth breathing and facial morphology .
In the comments at the end of the article, the researchers also pointed out that there is still a lot of controversy over whether mouth breathing can cause long-face syndrome at . Many clinicians believe that mouth breathing itself may not affect a person’s facial appearance, but if the person has excessive vertical facial growth, which is the genetic tendency of long face syndrome, then mouth breathing is most likely to cause changes in his facial appearance. A factor. This passage of
is not difficult to understand. In summary, is if you are an ordinary person and do not have the genetic tendency of long face syndrome, mouth breathing will generally not make you ugly. But if you have a genetic predisposition for long face syndrome, you may not be sure.
Why did they become ugly?
Since mouth breathing does not cause gland-like faces for ordinary people, how should the two examples in the first part of the article explain?
In fact, the reports of the above two cases are from the same person, his name is John Mew. Who is
John Mew? The famous British orthodontist, the "mewing correction method" or Orthotropics, which is very popular on the extranet, is the "great god" invented [5].
The old man looks like this
This correction method is to change the jaw line and face shape by changing breathing and chewing. However, in fact, the correction method does not have any scientific basis, nor has it been recognized by mainstream academic circles. It is a very controversial .
Despite this, in this society where beauty is increasingly valued, the "mewing correction method" is still popular on both social media and video sites [6].
Most of the people who advocate this correction method on social media are really effective. They claim how effective the correction method is. However, some scholars speculate that their face and jaw contours are likely to change naturally during adolescence. It is not the result of the correction method [7].
In 2010, in order to prevent the further dissemination of this non-scientific correction method, Dental Comprehensive Management Committee publicly condemned John Mew's false propaganda, and revoked his dental license [6].
Although things are here, it seems trueIt became clear, but the two cases from John Mew have not stopped their impact on people. People still hold the attitude of "I would rather believe it and not believe it", and would rather believe that "mouth breathing will lead to glandular appearance." "This hypothesis has not been recognized by the scientific community. Even, in serious cases, more and more unsightly facial features will be blamed on mouth breathing, which is probably the biggest pot of mouth breathing.
If you think so before, I hope this article can change your anxiety about appearance. Appearance is important, but it is unnecessary to be obsessed with appearance and believe in a statement without scientific basis.
Does mouth breathing still need to be corrected?
Since "mouth breathing will cause glandular appearance" is not a scientific conclusion, is mouth breathing still necessary to correct it?
First of all, it is certain that everyone cannot avoid certain mouth breathing. For example, when allergies or colds cause nasal congestion or glandular hypertrophy causes nose congestion, people will switch to mouth breathing. A short time may not have any effect on us, but chronic mouth breathing in can cause bad breath and gum diseases [8].
In addition, there is evidence that, compared with adults who breathe through the nose, people who frequently breathe with the mouth of are more likely to suffer from sleep disordered breathing, fatigue and poor quality of life, and may even increase snoring and obstruction. The risk of sleep apnea [9].
Therefore, if it can be corrected, it is better to breathe through the nose. After all, the meaning of the nose is not only good-looking, but also more important-breathing.
