Where does a man's body odor come from?

Exploring the mystery: What is "manly smell"? This shows that, just like women, men also have a smell that highlights men's characteristics. Medical experts use a special term to describe it, called body odor. So do you know how manly smell comes from?

The role of male body odor

Don't underestimate men's body odor, it has a great physiological effect! Scientists have found that the faint, sometimes light, sometimes heavy smell of men has a significant impact on women's spirit, emotions and sexual desire. For example, researchers collected odor from men's armpits, mixed it with alcohol, and applied it to the lips of a group of unmarried women with irregular menstruation. After a period of time, menstruation unexpectedly returned to normal. This is also the secret of some scientists' idea of ​​making male odor into vanishing cream or perfume as a female health care product.

What's even more amazing is that a man's body odor can influence women's mate selection to some extent. Psychological research shows that women pay the most attention to the smell of a man rather than his eyes, and they are most likely to be attracted to a man whose body odor is similar but not identical to that of his father.

The reason is: body odor can reflect the strength of a person's immune system. Women have the natural ability to identify different men's antibodies based on different body odors, thereby maximizing the chance of giving birth to healthy children.

It can be seen that there is a scientific reason why women are fond of men's body odor. A survey data confirmed this: 71% of men and women think that body odor is an important "sexual aphrodisiac"; more than 50% of women think that musky body odor is the sexiest, and about 25% of women prefer spicy body odor.

What is the standard masculine smell? - It is said that the most standard masculine smell should include the smell of tobacco, mothballs, sweat and socks.

The ins and outs of masculinity

Men's body odor is composed of sweat and sex. Sweat comes from the secretions of sweat glands on the body surface. The secretions of sweat glands have no smell. It is only after contacting the skin and being "brewed" by bacteria that the smell comes out. The main odor substance contained in sweat is butyrate.

Once the skin hygiene is poor, bacteria feed on the oil secreted by the skin. As the oil decomposes, the smell becomes unpleasant, and the sweat fragrance becomes sweat odor. In summer, mosquitoes chase people and police dogs use their sense of smell to track down fugitives, all because of the influence of sweat fragrance.

Sexual fragrance is different. The substance that produces this kind of scent is due to the external hormones secreted by the human body. These external hormones are "brewed" by the exocrine glands in the armpits, head, face, chest and genitals, and are also called pheromones. American scientists have separated 11 types of pheromones from human skin cells. These mysterious substances invisibly affect people's basic behaviors, such as mutual attraction between the sexes. At the same time, everyone has their own unique pheromones, just like everyone has their own unique fingerprints.

In addition, substances released by the human body during metabolism can also produce certain smells. According to experts, there are more than 900 kinds of smells, including 149 kinds emitted from breathing gas, 196 kinds from feces, 151 kinds from sweat, and as many as 271 kinds emitted through the skin. It is these smell substances that mix to form the masculine or feminine smell.

Editor's note: Men often secrete androstenone from their armpits, which has a musky smell. They also emit this smell when they sweat... The function of men's body odor

Where does a man's body odor come from?

Swiss researchers have found that men's sweat smells like cheese, while women's sweat smells like onions.

At a Swiss company that studies taste and odor for the food and fragrance industries, researchers took armpit sweat samples from 24 men and 25 women after they had either cycled on an exercise bike for 15 minutes or spent time in a sauna.

After analyzing the samples, the researchers found that the women's sweat contained large amounts of an odorless, sulfur-containing compound. When this compound mixed with bacteria commonly found under the arms, it transformed into chemicals called thiols, which are famous for their onion-like smell.

Men's sweat is different. Researchers have found that it contains a large amount of an odorless fatty acid. If this fatty acid comes into contact with enzymes produced by underarm bacteria, it releases a cheese-like smell.

"Men smell like cheese, and women smell like grapefruit or onions," said Dr. Starkenmann, who led the study.

It is believed that this research can be used to develop deodorants for men or women.

But not all researchers believe that this experiment is universally applicable. Because people in other parts of the world may not have the same eating habits and genes as the Swiss. Professor Jacob, who studies the science of smell at Cardiff University in the UK, said: "Other factors include what you eat, what you use to bathe, what clothes you wear, and the genes you inherit."

Someone once joked: Our lives are getting better and better, but our bodies are getting stinkier. Westerners eat a lot of meat, so their body odor is stronger, especially in the summer, which is even more unacceptable.

The most problematic type of body odor is the odor from your armpits. The reason why your armpit sweat smells bad has a lot to do with what you eat...

If the alkalinity in the blood is not enough to neutralize the harmful acidic substances produced, these acidic substances will be secreted by the sweat glands in the armpits. These secretions include fat, cholesterol, and other acidic substances that have not been completely neutralized. They gather in the armpits and emit a strong and unpleasant odor. Therefore, it can be seen that trying to keep the blood at an ideal alkalinity is the only way to prevent body odor fundamentally.

If you change to a vegetarian diet and add more green vegetables and foods rich in iron and magnesium to your daily diet, the blood will gradually become alkaline and neutralize the original acidic blood. After the blood quality gradually changes, the sweat excreted will no longer have an unpleasant odor.

In addition, seafood, onions, garlic, pepper, fennel and curry, etc., these foods will produce protein and fat decomposition products that seep out of the body through the pores. The volatile odor of these foods can even be secreted by the sweat glands to the feet. Therefore, if you want to smell fresh, stay away from these foods.
