A good boyfriend
Go to work refreshed during the day
Sweat smells like smoke in the evening to return home
The same is crowding the bus
Stand in the middle of a bunch of men and stand in the middle of a bunch of women
Men's Sweat vs Women's Sweat
Is it really different?
Sweat stinks, is there a solution?
perspire
It is an important means for the human body to regulate body temperature
Whether it's a man or a woman
99% of the sweat is actually water
Sweating of the human body
Thanks to the two great heroes[1]
● Exosome sweat glands (small sweat glands)
There are millions of them, all over the skin of the body
Most on the palms and feet
● Parietal sweat glands (large sweat glands)
It is mainly distributed in the armpits, areola, anus and perineum
Close damp areas
And sweat mixed with odor
Mainly the flora in the sweat glands is messing around
In particular, it is mainly in places with large sweat glands
There are a large number of fungal communities growing here
When encountering sweat, it is rancid by bacterial enzyme acids
Produces carboxylic acid and sulfide gases
It stinks so badly that it makes people head-on....
look at! A swarm of bacteria is bouncing around the grave
(Source: BBC documentary Life on the Human Body)
And the hands, face and other parts
No matter how much sweat you sweat, it generally doesn't stink
Because they are exposed
It is not easy to breed bacteria
generally
The smell of sweating "stinky men"
Mainly armpits, chest, feet, etc
Sites with many bacteria are emitted
People with strong oil secretion
It is also more susceptible to sweat odor
Especially parts such as the scalp
This stinky smell of sweat! who! accept! get! finish!

In fact
The smell on the human body is similar, and the ingredients are similar
It's just that there is a difference in concentration
So why do we always feel that men stink more?
Currently, scientists have proposed these possibilities [2-4]
1, the woman's "specific" function
Women are not only better at detecting odors
It is also more sensitive to odors on the opposite sex
2, men's sweat glands are more developed than women's
The human body odor is mainly emitted by the large sweat glands
Large sweat glands are greatly affected by androgen stimulation[8]
And from adolescence
Men have higher androgen levels than women
So the man's body odor is naturally heavier
3. Disturbed by dietary factors
Some men prefer to smoke and drink
It also has a greater impact on body odor
The study also found that meat intake
Changes the composition and secretion of fatty acids in the axillary[5]
Carnivorous man, leisurely oh ~
Foods like chili peppers, onions, garlic and so on eat too much
It also affects body odor
Men and women should pay attention to Oh~
4. Problems with living habits
Girls love to be clean and take a shower and change clothes frequently
Naturally, bacteria multiply slowly
Girls like to spray perfume and apply skin care products
To some extent, it masks the body odor
Sensitivity to "smell"
At the end of the day, it's a more personal experience
It carries pheromones of human emotions
It is affected by emotions and subjective feelings
A girl on the Internet once shared one of her own experiences
Oh, fickle woman
Many in the animal kingdom choose their spouses by smelling
Smell is an exchange of pheromones[6]
So
Maybe the "stinky" smell of your boyfriend's body
It belongs to his unique manly taste

In order to reduce the number of times the "stinky sweaters" are rejected
In line with the principle of saving money and effort
Please put away this "Sweat Removal Guide"
1. Rinse carefully
Remember to focus on cleaning these areas
Scalp, armpits, genitals (especially for women)
2. Penetrate the clothes that absorb sweat
In summer, you can choose cotton material clothes
Boys play and wear a tank top
It is easier to dissipate heat and sweat
3, anti-odor focus - armpits and feet: bacteriostatic + antiperspirant
Bacteriostatic soap can be used
Spray antiperspirant (especially the armpits) in advance
It is also possible to use desiccants and talking powders containing zinc oxide powder
Sweaty feet change socks frequently
4. Eat less foods that stimulate sweat secretion
Put down the wine glasses and cigarette butts
Stay away from spicy, irritating, and heavy-smelling foods
Of course, if the sweat stinks badly
On an adequate budget
You can also go to the dermatology department of the hospital
Doctors may recommend medication
For example, the underarm injection of botulinum toxin inhibits the secretion of sweat glands
However, this therapy can only be maintained for a short period of 2 to 8 months
If the drug therapy is ineffective in severe patients
Doctors may recommend surgery to remove the large sweat glands
Achieve the purpose of radical cure
Finally, we have summarized several sweating problems that both men and women are concerned about, let's take a look at the answers!
1. Can sweating detoxify?
There is actually no poison in the sweat. Remember, the only physiological meaning of sweating is "heat dissipation", keeping the person's body temperature constant at about 37 ° C. What sweating, sweat steaming can detoxify the saying, don't believe it!
2. Is it good for the skin to sweat during exercise?
Many people sweat a lot of exercise, they feel that their face is smooth, the skin is smooth, this is because a large amount of sweat excretion makes the surface of the skin hydration increased, only a short-term effect. After a while, the skin should still look like it.
Of course, exercise is a good thing, and it is naturally better to sweat during exercise. However, deliberately seeking to sweat and wearing sweating clothes may lead to hypokalemia and quadriplegia due to excessive perspiration [9].
3. After sweating during exercise, can I take a bath immediately?
It is recommended to rest for half an hour before taking a shower after exercise. At the end of the exercise, the blood vessels of the human skin are dilated, and if you take a bath immediately, it will cause the skin blood vessels to contract, but the heat dissipation will be blocked and the body temperature will rise.
It is best to take a gentle bath, preferably with warm water, about 39°C in summer (at 25°C in the bathroom) and around 42°C in winter (at 14°C in the bathroom).
4. Sweating a lot, does it mean that the body is "weak"?
In fact, most people are "physiological sweating increase", such as exams, sweating more when dating is stressful, sweating a lot when eating, sweating more on the hands and feet, most of them are normal and have nothing to do with disease.
However, beware of diabetics, as 50% of patients with type 1 diabetes have dysphoria and need to monitor blood glucose if sweating becomes significantly higher [7].
If at normal room temperature, sweating is so much that the sheets and bedding must be wet and must be replaced, it may be the so-called "night sweats", also called drenched sweating, it is recommended to go to the hospital for further examination. Because this may be related to infectious diseases (most commonly tuberculosis), neurological diseases, tumors, hyperthyroidism, etc.
So, today, have you been "stinked" by men?
