Is it reliable to find objects through experience?

Author:Science popularization China Time:2022.09.26

We store rich biological information in our body taste, which can not only reflect human health, eating habits, but even the characteristics of judging personality. Taste also occupies certain factors in terms of spouse selection. In one study, women randomly obtain a T -shirt that men pass through and sort them according to their preferences. Kiss. This shows that there is a deeper gene through odor selection, because human instincts will choose a better -breaking offspring with HLA to reproduce better offspring. Of course, many people use perfume to cover their own experience. Of course, perfumes are attractive, but they are actually a double -edged sword.

In 1682, Louis XIV came to a hunting base left by his father with a member of the royal family. It is the stronghold, in fact, it is just a few simple huts. Louis XIV made a cost -effective renovation and renovation, and he planned to settle there. This is a major decision, because the previous France is similar to a nomadic regime. The royal family migrates around with the seasons, and only returns to Paris every year to live in Paris every year.

This cabin was the later Palace of Versailles.

At that time, the Palace of Versailles was far from a place suitable for living. The renovation project has not yet been completed. It is said that there are large large swamps next to the palace. There are sewage pits and animal corpses and excretions everywhere.

Such a description is inevitable that it is exaggerated, and the ruins and dirt of the Palace of Versailles can be seen. When we realize this today, it seems that it is not difficult to understand why Louis XIV is so keen on perfume -who has changed in this stinky environment, you have to think about it The smell, right?

Speaking of which, Louis XIV is a very fashionable monarch. The "three -piece set" of fashion ladies -perfume, high heels, and wigs have a deep relationship with him. However, love to use perfume may not be out of his fashion taste. According to legend, Louis XIV's personal hygiene is worrying. He has a few times in his life. In order to cover up the unpleasant manifestation, he often spray perfume.

So the question comes: What is the reason for the experience? In other words, what factors are affected?

Why is there a sense of appreciation

A more straightforward reason is personal hygiene habits. This is how Louis XIV's appreciation came. We often have such experience. If we sweat more, we seem to have a difficult smell on the body. In fact, nearly 99%of the sweat is water, and the remaining little point is salt and urea. There is no odor in itself. The pungent smell of the figurine is the body surface microorganism that combines the sweat.

Khan is secreted from the sweat glands. There are two types of sweat glands: one is evenly distributed on the whole body, which can help people emit calories and be called external secretion glands; the other is top -saving sweat glands, which are mainly distributed under the armpits, areola, and the navel. The sweat secreted from the top of the top of the top is different from the ingredients secreted by the outer gland. In addition to water, salt, and urea, this sweat also contains fat, protein and other substances. When the skin surface (such as microbacteria, good oxygen leukine, propion bacteria, etc.) break down these substances, it will produce a sulfur or ammonia -containing irritating odor, so it smells stinky; also because it smells stinky; also because of stinky; also because of stinky; also because of stinky; also because of stinky; also because of stinky; also because of because it smells stinky; For this reason, the smell of sweat is mainly emitted from places with more sweat glands.

But it is obvious that sweating is not the whole reason for the difference in body taste and the difference in body odor. There are many sources of appreciation, and there are some strange factors. For example, eating habits, physiological cycles, and even diseases can affect the taste.

What can you tell us what you can tell us

Taste can almost show all aspects of a person -it is not an exaggeration to say that it is smelling people.

Speaking of which, it is probably the rule of nature to distinguish between the other person's bottom ability. In the animal world, it can be used to distinguish the enemy and me. This is because the smell released from the body can be used as a olfactory clue. These smells reveal the identity information of the "master" and the body's metabolic status. Human body taste also has the same function.

We are releasing a large amount of gas organic compounds (VOC), some of which have odor -of course there are no odors. Taste is the combination of these hundreds of smelling gas. These gases are released through excreta such as breathing, sweating or urine feces, and varying from age, eating habits, gender, and physiological state, and can even reflect the difference in genes. Therefore, appreciation is also regarded as "odor fingerprints" of everyone.

For example, appreciation can reflect a person's eating habits, and some research shows that eating more meat is more conducive to producing a pleasant appreciation [1]; even the physiological cycle is also fun, and women's experience will become more charming in the follicle period. It is more attractive, and the level of testicular hormones of men can also make them more fragrant [2]. When we are sick, the metabolism will cause a certain degree of disorders, which will produce some "unconventional" gas organic matter, or change the proportion of each component in the gas organic object under normal circumstances. Variety. For example: patients with tritaminicine can exhale trigamine. There are pyruis in the gas exhaled by diabetic patients. Patients with liver disease badge are found in the breathing of patients. This may be derived from the changes in hormones in the body, or the symbiotic bacteria in the skin surface, sweat and sebum [3]. From the perspective of smell, the cholera patients are "smell" sweet, and the body taste of patients with acute diabetes is a bit like rotten apples [4]. In addition to revealing the health status, appreciation also affects our personality evaluation, but this influence is somewhat unknown, we may not realize ourselves.

It should be said that it is a very complicated scientific issue. And if you spray perfumes and apply cosmetics, the problem will be more complicated.

Where does Xiang come from?

Where does the perfume "fragrant" come from? It is actually a combination of many molecules. Open a bottle of perfume, you smell hundreds of molecules in the air, and then get into your nose. The smell of each molecule is actually from the vibration of chemical bonds in the molecule. Some molecules have the fragrance of green grass, such as the commonly used as a smooth-3-hexiene -1-alcohol that is commonly used as a green leaf, and some molecules-such as H2S-but a smell of stinky eggs, because of different molecules and Different connections have their specific frequency. (Of course, according to this theory, as long as you find a chemical bond that is exactly the same as the frequency of molecular keys in H2S, the molecules formed by it will also have a smell of egg smell, so you can create any smell you want according to this principle.)

Some people tend to use perfume (or cosmetics with fragrance) to make their own taste better. But this brings a question: After the perfume is mixed with your original taste, will its role be "covering"? Or will the two be intertwined and mixed, showing a "new experience"?

In fact, perfume is a "double -edged sword". Although it can block the natural taste of the body, it may also enhance the original taste. Some scientists have found that after spraying perfume, the "new body taste" after the smell and natural taste of the perfume and natural body taste are better or even more unpleasant. Function, rather than simply cover up. This is why buy perfumes to choose a perfume that can match our own appearance, but not to look at the explosive model.

Perfume Charm Bonus

We may all have a feeling, that is, if you spray perfume, it seems that others look at ourselves. This is not an illusion. There are many studies that have confirmed the role of perfume and cosmetics with aroma in personality evaluation.

Perfume may affect the attraction of others in our eyes. Studies have shown that if there is an unpleasant smell in the environment, a face with a high face value seems to have no appeal at once. Studies have shown that perfumes will even control our professional ability. For example, during the interview, if you spray a little male perfume, you will be considered to be better than a management position. On the contrary, if a female perfume is sprayed, the interview results of the application for management may be a bit bad [5]. So is the perfume must be an interview weapon? not necessarily. A statistical study involving many positions and many job seekers shows that for female job seekers, spraying perfume is more conducive to winning offers, and this conclusion has not obviously reflected in male job seekers [6].

Some studies have shown that when forming an impression of a person, it has played a very important role in it. People usually associate unpleasant odors to unpopular personality characteristics, which is scientific [7]. A series of recent studies have found that the evaluation of personality characteristics based on personality (especially the five personality traits of the five personality traits, etc.) is actually accurate [8].

What is the characteristic of the characteristic characteristics of the personality characteristics?

First of all, we know that the physiological functions of the human body are related to specific hormones and neurotransmitters. Therefore, they can become a bridge of experience and personality, especially for nerve quality and dominant personality. ]. Secondly, some emotions are considered to be caused by the taste [12], and people who often express a certain emotion may have the corresponding experience [13]. For example, frequent sweating caused by anxiety and nervousness may change the sense of neurosis. This is another reason for the relationship between the personality and personality.

Genes

In fact, we can change body odor by changing eating habits or regulating body functions. However, there is a factor that we can never change, that is, genes -genes may be a key factor that makes you smell different from others.

Each of us is unique, and our sense of smell is sensitive enough. Some people have done experiments: mixing a pair of twins T -shirts in a pile of irrelevant T -shirts, and then let the subjects smell the smell from these T -shirts, but found that the subjects can easily use it to make it possible The twin T -shirts are identified; and the twin's body taste is similar, so that the subject will even mix the smell they smell from the same T -shirt or two [14]. Agnieszka Sorokowska, a scientist at the University of Ferzwaf in Poland, believes that this shows that genes really affect our appreciation, so theoretically, we can detect genetic information by smelling the smell on our body.

So, what is the use of these genetic information hidden in the appreciation?

In a study, female subjects got some T -shirts worn by men and asked them to sort them according to the degree of joy of the smell. The result is very interesting -the order of their excretion is completely in line with the differences between them and the Human Leukocyte Antigen (HLA) [15].

HLA is a protein that helps the immune system to identify which cells belong to their own body and which cells come from the outside world (and these cells from the outside world may be potential pathogens). The gene encoding HLA is called MHC, which is also a protein encoding that works in immune response. Therefore, HLA can be used as a starting point to allow scientists to understand what types of protection a person can provide.

Your "HLA Portrait" is likely to be different from anyone else -of course, a loved one with a very close relationship with you will have a more similar "HLA portrait". From a genetic and genetic perspective, the descendants of the other half with a different "HLA portrait" can give birth to children with more immune advantages. Sorokowska explained: "If your other half is different from your genes related to your immune system, then your children may have stronger resistance to the pathogen."

The sorting of T -shirts for women's subjects just ranks the first -facing man with the largest difference between "HLA portrait". The most similar men in "HLA portrait" are in the end, which actually reflects a genetic preference. Of course, they didn't know that genes made a choice for them.

As for how the difference between HLA leads to the pleasure of body taste, it is unclear. Some people think that HLA can produce specific substances, and these substances can be digested by bacteria on the surface of the skin, so HLA actually regulates the body taste by affecting the skin flora.

Understand the science behind the taste, but you don't need to blindly follow the guidance of the taste

Will people use this genetic information behind the body to choose mate? Um, it doesn't seem to be. A study surveyed the 3700 couples, and the probability of choosing the other half according to the degree of HLA differences was almost selected. , But it will not determine the marriage object.

From the perspective of evolutionary biology, the basis of women's mate selection is undoubtedly very important. Most species in nature are females when "wedding matching", and the basis of "their" choice is ultimately found to find the most dominant opposite sex in genes so that they can bred offspring with better sexual traits (nature tells us in nature tell us , Gongsheng and Education must start from looking for men.) This is why most male animals in nature have colorful appearances, can sing and dance, and also give gifts -this is the means they use to show their strong genes.

The relationship between the preferences and the genetically giving birth to a business scripture. The active businessmen have made a fashion that is nicknamed "T -shirt Quick Dating", and even develops a "mailing experience" service. But can such services really make single men and women quickly lock the people? Or a proper IQ tax?

Here we need to figure out a psychology, that is, in actual life, although we really prefer something, it is not necessarily based on this preference. This is because the real life scene is very complicated. For example, based on the body taste, we can make an evaluation of personality traits. We may judge "ah, this person has a good temper", but when we see a photo and a body -style sample at the same time, we may be again again I will feel that "although this person has a good temper, but that person is obviously more handsome." Even SOROKOWSKA believes that although the personality is more accurate and reliable based on the body taste, it is simpler to look at the face, and the human nature will often choose the simpler (not necessarily more correct) option.

In another study, Mehmet Mahmut, a sense of smell and odor psychologist at McCaru University in Australia, found that unmarried men's appreciation smells stronger than married men [17]. He speculates that this may be because the higher the testosterone level, the stronger the appreciation, and the testosterone level is related to age. The age of married men is greater than unmarried men as a whole. Therefore It will fade.

Speaking of which, we seem to be able to detect what the evolution of millions of years wants to tell us what to tell us. The information of a person's reproductive ability seems to be written into the appreciation. However, we must "listen" to the command of the body, choose the other half of the gene preference? If you just want to find a spouse with an advantageous gene, then you should really pay attention to the opposite sex. But love is complicated, so we don't need to pay too much attention to the appreciation -after all, we have used a long evolutionary time and have already lived in the look of the body.
