A kind of body odor for men's eugenics

"Taste" by Xin Xiaoqi: "I miss your smile, your coat, your white socks, and the smell of you..." Are there times when, when he gets close to you, that faint, refreshing masculine scent makes your heart flutter? Are there times when, when he gets close to you, that strange smell makes you want to run away? The smell of a man is no small matter, it directly determines your attractiveness to the opposite sex.

A report published by the Department of Psychology at Brown University in the United States in 2002 showed that in the ranking of male attractiveness, body odor was ranked first by women, and appearance and social factors (except for "pleasantness") were not as important as body odor. Therefore, it is very important for men to keep their body fragrance and get rid of body odor.

Let’s first see what “stinky men” usually stink the most!

1. Bad breath

Power index: ★★★★

Radiation range: ★★

If you are used to smoking, drinking, and eating garlic, it is recommended that you pay attention to your surroundings and be kind, and try to reduce your own lethality. You can drink more tea on weekdays, because tea contains anti-radiation ingredients.

2. Armpit odor

Power index: ★★★★★

Radiation range: ★★★★★

This type of player is a natural disaster or man-made disaster.

3. Lower body

Power index: ★★★

Radiation range: ★★★

Lazy people usually have this problem. There is really no other reason except that they don't take a bath often. So I advise my brothers to take a bath frequently in summer and choose shower gels containing mint as much as possible.

4. Smelly feet

Power index: ★★★★

Radiation range: ★★★★

There are two situations that can cause foot odor. One is that the congenital sweat glands are abnormally developed, and all the sweat is discharged from the lower three routes; the other is acquired laziness, such as not washing socks for 10 days and not changing shoes for 3 months.

Where does the masculine scent come from?

There are three types of glands in our skin: sebaceous glands, sweat glands and apocrine glands. Sebaceous glands are responsible for secreting oil to moisturize the skin and do not produce body odor. Sweat glands secrete water and salt and do not have any odor under normal circumstances. The main source of body odor is the secretion of apocrine glands, which some people call "sexual fragrance". Apocrine glands only start to secrete after puberty, that is, during sexual maturity. In other mammals, the secretion of apocrine glands is a courtship signal called "pheromone", which is used to advertise to the opposite sex within a few miles: I am ready!

When men are nervous or excited, the apocrine glands secrete more vigorously. Men with dense body hair have stronger body odor because body hair makes it easier for the secretions of the apocrine glands to spread. Men grow thick armpit and pubic hair after puberty, which may promote the spread of body odor and attract the opposite sex.

His body odor indicates whether he is a good candidate for eugenics.

Recent immunological studies have suggested that male body odor may be related to eugenics. Studies have found that there is a group of genes on the chromosomes of vertebrates called MHC (major histocompatibility
complex, the gene product of which plays an important role in immune regulation. MHC is inherited from both parents. If we inherit a gene from one parent that recognizes disease A and a gene from the other that recognizes disease B, then our immune system can fight both diseases.

The experiment found that female mice would choose the one with the biggest difference in MHC from their own suitors, and the greater the difference in MHC, the more likely it is to bring healthier offspring. However, the way female mice choose is not very elegant - by smelling the urine of male mice, the smell of male mouse urine can represent its MHC to some extent.

Although we humans are rarely interested in the urine of the opposite sex, we may use the same principle to interact with the opposite sex through body odor.

This theory was confirmed by Swiss researchers. They found that women are indeed most attracted to the smell of men whose MHC is very different from their own. Moreover, when women smell the body odor of men with a large difference in MHC, they are more likely to recall their ex- or current partners, indicating that body odor determines to some extent who we will date and fall in love with.

Even if the difference in MHC is large, if the body odor is strong enough, women will still evaluate it as "unsexy" and "unpleasant." Because strong body odor is often a manifestation of a certain disease, women are warned: stay away from this man, his genes will affect the health of my children.

Smell a man

Researchers suggest that perhaps you can smell whether this man can give you healthy offspring by the following methods.

1. Pick a "no-scent day" and have him bathe with no-scent soap, wear a clean cotton T-shirt, and stay away from smokers and any perfume. Make sure you don't have a cold, haven't been in contact with smokers for a few days, and have a normal sense of smell.

2. After he wears the T-shirt for a day and a night, hug him from behind and smell his breath. How does it feel? Very sexy? Congratulations! He is qualified to be the father of your child!

3. Does his body odor seem unusually strong? If his body odor is sweet, it may be a sign of diabetes. You should consult a doctor in detail before deciding to have a baby.

4. If you feel that you two are not as harmonious and intimate as before, check his diet to see if he has added any spicy food or a lot of garlic recently. These foods will affect body odor. In addition, some laundry detergents will also produce unpleasant odors when mixed with body odors. Try changing his brand.

5. You are the most qualified person to choose perfume for him, and you know best which fragrance best matches his body odor.

When a man smells bad

If a man's scent changes and turns into body odor, he will have no sexual appeal at all.

Most people think that body odor is caused by sweating, but the secretions of sweat glands themselves have no smell. The unsaturated fatty acids produced by the interaction between the organic substances contained in them and the bacteria are the source of the odor. Smoking, drinking, spicy food, constipation caused by an unbalanced diet, or a lack of magnesium and zinc in the diet may cause body odor. In addition, hypoglycemia, diabetes, liver disease, parasitic diseases, metabolic dysfunction, and mental stress may also cause body odor.

Long-term use of certain Western medicines or vitamins can also cause the body to emit a special odor. Here are some recommended ways to help him prevent and treat body odor:

1. Encourage him to take more showers and change clothes frequently. After washing his body thoroughly with soap, wipe it dry and apply antiperspirant to his armpits immediately. Armpit sweating accounts for less than 1% of the body's sweat, but it is the source of more than 90% of sweat odor.

2. Wear breathable socks, change socks frequently, and try not to wear the same shoes for several days.

3. Use a cloth dipped in hydrogen peroxide solution to wipe the areas prone to body odor such as the armpits, feet or groin to kill bacteria and eliminate body odor.

4. Remind him to quit smoking and drinking, avoid eating a lot of meat, seafood or high-fat and greasy food, and avoid foods with strong odors, such as garlic, fennel, curry and onions. These foods are easy to produce protein and fat decomposition products, which seep out of the body through the pores.

5. Keep your mood stable. When you are nervous and distressed, the sweat glands in the nose, armpits, groin and around the genitals become active, the decomposition of staphylococci is accelerated, and the production of short-chain fatty acids increases, which is the main producer of sweat odor.

6. Insist on detoxification. Foods that help detoxify include: various vegetables, kelp, mung beans, mushrooms, livestock and poultry blood, papaya, apples and tea. Drink more water to increase urine volume, so that more metabolic products can be discharged from the urinary tract, thereby reducing excretion from the skin.

7. Seek professional help: If the body odor is very stubborn, it is best to accompany him to see a doctor. The doctor will recommend more treatment methods. For example, underarm odor can be treated with superficial X-rays, carbon dioxide laser spot-on therapy to burn the hair follicles to destroy the sweat glands, etc.
