Let's start with three small surveys:
How many girls like to smell the smell of male tickets?
How many boys like to smell the smell of female tickets?
How many couples are together because they like to smell each other's body?
Welcome to share your experience in the message area.~
After doing these three surveys, I believe that many couples can't hold back and begin to recall those years... I like the faint fragrance of his body, the smell of cigarettes, the smell of grass, the smell of milk, the smell of roses, the smell of sweat or the unique taste of inexplicable.
Therefore, a lot of love may start from liking the smell of ta's body, so a word called "smell love" has emerged. This is probably what is often said to be "smelling the same, attracting each other". (Single Wang Xingren said: This is the reason why I haven't found a partner yet)
Wondering why scented love happens? Why is the body odor on each person unique and different? Today Ben Hong will take you to understand the mystery of [body odor].
The origin of the body odor
Body odor refers to a unique smell emitted by the human body outward. It may be a favored fragrance, or it may be an unpleasant odor or pungent smell.
The same is the body odor, why is someone "body odor" and some people are "body odor"?
Most of the human body odor comes from the largest organ of the human body , the skin. The skin contains two types of glands: sebaceous glands and sweat glands. According to the different secretions of sweat glands, it is divided into two types: large sweat glands and small sweat glands.
In addition to lip red and nails, small sweat glands are widely distributed throughout the human body. The secretions excreted by the small sweat glands are mainly water, inorganic salts and a small amount of uric acid, urea and other metabolic wastes, which are generally diluted and have no special taste.
The sweat glands are mainly distributed in the armpits, areola, umbilical fossa, vulva, anus and other parts, it secretes substances containing a variety of proteins, sugars and fatty acids and other substances, after being decomposed by human epidermal bacteria, causing the multiplication and fermentation of bacteria, it will be easy to produce a pungent odor.
So that's how the smell that makes people "smell discolored" comes from. From this point of view, body odor and sweat glands are almost inseparable, for example, the occurrence of fox odor is inextricably linked to the sweat secretion of sweat glands.
In fact, there are many factors that affect the "heavy body odor", such as:
●Genetics
The first is genetically determined. Secondly, when your chromosomal alleles are expressed in GG and GA, the sweat glands secrete special molecules and organic acids, which are broken down under the action of bacteria, resulting in an unpleasant taste.
●Food and medication intake
For example, after eating leeks, garlic, onions, taking drugs, etc., the smell is emitted from the respiratory tract, sweat, and urine, and the body odor will also occur.
●Disease
Metabolic diseases (eg, phenylketonuria, trimethylamineuria) or systemic diseases produce smells, such as the smell of rotten cabbage in patients with tyrosine metabolism disorders, and the exhaled gas of diabetics with the smell of rotten apples.
●The thing outside the body "smoked"
For example, the smell of daily necessities, cosmetics or clothes for daily use.
Different people will have different smells?
Manly
There are two main sources of masculinity that you think of. One is sweat incense; the other is sexual incense.
● Sweat fragrance
Derived from the secretions of the sweat glands on the surface of the body, the secretions themselves have no taste, but after contact with the skin, coupled with the "brewing" of bacteria, the taste comes out, and the main odor substance contained in the sweat is butyrate, in addition to lysine, lactic acid, urea and so on.
Once the skin hygiene is not good, bacteria will feed on the oil secreted by the skin, and with the decomposition of the oil, the taste will become unpleasant, of course, the sweat fragrance will naturally become a sweat odor.

●Sexual incense
"Smell love" is related to substances such as sexual incense, and is also often referred to as "pheromones", which are pheromones secreted by the human body, also known as exohormonal hormones.
These external hormones are "brewed" by exocrine glands in the armpits, head and face, chest and genitals, and then detected by the olfactory organs of other individuals, thus invisibly influencing changes in people's basic behavior (emotional, psychological or physiological mechanisms).
For example, the smell of the other party can attract you, or you can smell the "pheromones" emitted by the male ticket and he and others can't smell it, which is probably the smell of love!
womanly
I believe that many boys will have such an experience, when girls pass by you, you can always smell a faint fragrance. Regarding the "body fragrance" of girls, there are three theories.
The Doctrine of Sweat Fragrance
Girls and boys also emit sweat smell, and there are also sweat secretions (butyrate, lactic acid, urea, etc.) these substances are present.
But Ben Hong believes that most girls are still very particular, love to bathe or even take good care of them, and will not let bacteria have the opportunity to grow and reproduce on the surface of the body. After all, what girl doesn't like to smell fragrant!
The doctrine of sexual incense
It is also due to substances such as [pheromones], [pheromones] will appear through the discharge of sweat or sebum in the woman's armpits, perineum, breasts and other parts, this hormonal personality physiological odor, the opposite sex may be attracted to each other by this slight odor.
The theory of exotic aromas
If the boy smells neither the sweaty scent of skin secretions nor the sexual scent of extrasexual hormones, there is also a humorous saying that "it is pickled by cosmetics".
Girls are exposed to a variety of shampoos, skin care products, perfumes, cosmetics, etc. every day, which contain a variety of fragrance additives, and the use of perfumed things for a long time remains on clothing or skin, which will produce the "same fragrance".
Childlike flavor
There is always a smell of milk on the child, and the parents can't help but smell and hug, which may be related to these points.
● The taste of residues: When the baby is still in the mother's belly, the body will be wrapped around a layer of white waxy substance called "fetal fat", and when the baby is born, the amniotic fluid residue and fetal fat cover the baby's skin, and the smell will have a milk-like smell.
● Milk smell caused: before the baby is 6 months old, they are breastfed, in addition to breast milk they can not eat other foods, so there will be a natural milk smell on the body. But after 6 months, the baby will be paired with complementary foods, and as the baby's intake of complementary foods increases, the milk flavor on the body will gradually disappear.
● Sweat glands are not developed: The reason why the baby has a milk smell on the body is also related to the fact that its sweat glands are not fully developed, even if sometimes they are covered in sweat, but the baby also has a milk smell, so it will not be like adults sweating after a sweat smell.
The taste of the elders
Sometimes approaching or approaching the elderly will smell a smell of elders, which has a certain relationship with age growth and metabolism slowdown.
The older the elderly, the slower the metabolism, the less antioxidants in the skin, coupled with hormonal changes, resulting in more free fatty acid oxidation, so that a substance called 2-nonenenal is produced, which emits a special taste.
In fact, this "elderly taste" is not unpleasant, but it may not be hygienic and clean, and eventually it slowly accumulates into a pungent taste.
In addition, the smell of the elders may also be caused by some diseases. After people are old, the skin resistance is reduced, more likely to be infected, and skin diseases such as dermatitis, eczema, ulcers, and pressure sores appear, thus emitting odors.
After introducing the small knowledge points about different human body odors, I would like to say what everyone wants to know, how can I make my body odor more pleasant?
Leave a small tip of incense
1, the smell of the body has a lot to do with cleanliness. If you want to make yourself a fragrant boy and girl, you can't be lazy, take a bath, change clothes, and wash clothes frequently.
2, make full use of some small items to create a "sense of fragrance", such as choosing their own perfume, aromatherapy, antiperspirant, deodorant, deodorant, especially for some people who have a peculiar smell or sweaty themselves, it is of great help. Or use some fragrant washing products when washing clothes, so that the clothes leave a faint fragrance when worn on the body.
3, try to eat less smelly food, eat more fresh breath of food, if you really do not want to give up their "taste preferences", then carry a small package of mouthwash or gum, in case of emergency.
4. Wear loose, breathable clothes, which is conducive to the evaporation of sweat.
Taste everyone has, everyone is different, friends, have you ever experienced a moment of social death or a warm and interesting thing about body odor? The comment area and Ben Hong chat about ding~
