1, what's in your underwear?
Underwear, an extremely private personal item, is closely related to health. Although many people can often wash and change their underwear, they don't know the service life, especially the elderly, who often wear it out and throw it away after deformation. As everyone knows, some invisible health hazards have emerged.
A pair of dirty underwear has an average of 0. 1 gram of feces.
Microbiologists all over the world have studied washing machines. A pair of dirty underwear contains an average of 0. 1 g of feces, and there are bacteria such as salmonella and Escherichia coli in the feces. Even if it is cleaned and dried correctly, it can't completely kill the bacteria on it.
One gram of feces contains 6.5438+million viruses.
One gram of feces contains 100000 viruses,100000 bacteria,10000 parasite cysts and1000 eggs. Although some bacteria and viruses are beneficial to people, most bacteria and viruses are harmful to people. Especially when feces pollute water, food, tableware and clothes, most harmful microorganisms will enter the human body and cause harm to people.
As early as 1964, Dr. Cameron of the United Kingdom inspected the underwear of 940 men in Oxfordshire, England, and found that their underwear was contaminated by feces to varying degrees, ranging from "wasp color" to "a lot of feces", so that Dr. Cameron greatly lamented: "There are so many people in our country complaining about such trivial things as traces of ketchup on restaurant tablecloths, but at the same time they are sitting in luxurious chairs in underwear covered with feces.
2. It is best to change underwear once every six months.
Qujing, deputy secretary general of China Knitting Association, said in an interview with Life Times that under normal circumstances, underwear with high frequency of use should be replaced once every six months. If the underwear is deformed, the material becomes dry and hard, and the stain cannot be washed clean, it must be replaced in time.
Change underwear: no more than 2-3 days.
We must form the habit of washing and changing underwear frequently in our life. It is recommended to change underwear every day, especially in summer, no more than 2-3 days. Separate from the coat when cleaning, and wash it by hand with soap as much as possible. Don't directly expose yourself to the sun after washing. Let it dry in the shade first, and then disinfect it in the sun. Otherwise, underwear will be hard and easily deformed. In addition, it is best to separate underwear. You can buy some special storage bags or put them in clean plastic bags to avoid dust and bacteria and affect your health.

Underwear worn during menstruation must be special.
Professor He Xiaohong, director of gynecology department of Hangzhou Hospital of Zhejiang Armed Police Corps, said: The adhesive on the back of sanitary napkins can make sanitary napkins stick to underwear firmly, but this adhesive will not be completely removed from underwear because of washing. Some sanitary napkins with poor quality have too much viscose, which can be felt by hands when they are stained on underwear. Director He said that it is impossible to judge whether this glue is a harmful chemical substance or not, and it is impossible to prove whether it belongs to the food safety category. No matter what substance it is, if it cannot be completely removed, it will directly threaten women's health.
Although there is no conclusive epidemiological survey data to prove that this adhesive is the reason for the increase of diseases in young women's private parts in recent years, Director He is confident that as an expert who has been engaged in clinical work for more than 20 years, she can make such a prompt from the perspective of women's health science.
Not only that, nine times out of ten, the girls in the clinic use rubber pads when there is no menstrual period. Because the position of the pad will move every time, the glue that is not cleaned in time will directly contact the female private parts. And these girls are all patients with female genital inflammation and vulvitis!
Do not wear underwear during menstruation; The use of small pads with adhesive is usually abandoned.
Moldy female private parts should wear disposable underwear.
Ren, the chief gynecologist, said: 80% of women may suffer from fungal inflammation of female genitalia, especially those who have sex.
During the onset of female genital fungal inflammation, you should throw away your underwear or boil it for disinfection, and don't dry it in the shade. It is recommended to wear disposable underwear during the attack, which can be discarded at any time.
If it happens after sex, you should go to the hospital with your sexual partner to see if there are related germs on his foreskin.

Chemical fiber underwear can inhibit sperm production.
The fabric of underwear is very important. After 20 years' research, an Egyptian doctor of medicine named shafiq found that chemical fiber underwear may lead to male oligozoospermia and cast a shadow on fertility. His research data showed that the sperm count of men wearing pure polyester underwear decreased significantly from 40% to 14 months, and that of men wearing semi-cotton and semi-polyester blended underwear decreased from 9% to 10 months, while the semen of men wearing pure cotton underwear remained unchanged. In addition, most men with semen changes return to normal after replacing chemical fiber underwear for 4 ~ 8 months.
This study confirmed that polyester underwear can temporarily inhibit sperm production. It will increase the testicular temperature and decrease the plasma hormone level, thus inducing oligozoospermia.
This is one of the consequences of wearing underwear by mistake: it leads to infertility and makes you lose the right to be a father. However, it is not only unmarried men who need to pay attention to underwear. Dr. Shafik also specifically warned men who have become fathers that polyester chemical fiber fabrics will generate electrostatic fields in Tintin's tissues, weaken men's sexual function, and even make you attached to sexual apathy.
Loose underwear is more in line with health needs.
Wang Rui, chief physician of urology department of the First Affiliated Hospital of Zhengzhou University, said that generally speaking, promoting loose underwear is more in line with the normal physiological needs of men.
Wang Rui said that if you wear underwear too tightly for a long time, the temperature of the scrotum itself will rise, resulting in abnormal sperm, necrosis and decreased mobility. He especially reminded that teenagers, in particular, are developing and must choose underwear with good quality and suitable pants.
In addition, urologists in the hospital found that many men, Tintin, were deformed and bent to varying degrees. The reason is that people often wear tight underwear. Tintin was oppressed for a long time under the bondage of tight underwear. How can he not bend over?
5. What color underwear is the best?
The color of underwear should also be treated with caution. Some people like dark underwear, but forget that the color is dyed by dyes, which are a hodgepodge of various chemicals and contain certain toxicity. As for white underwear, there may be some hidden dangers due to excessive bleaching, which will increase your risk of becoming attached to allergies.
Now you should understand that underwear is not a trivial matter, it carries multiple functions, such as protecting sexual organs, reducing the friction between thighs and trousers, and preventing odor from leaking out. Therefore, we must choose carefully and put health first, followed by comfort and fashion. Remember, wearing the right underwear is a sign that men care about themselves.

7. How to wash women's underwear?
Many details in life are closely related to health. Women's physiological structure makes them more vulnerable to external bacteria, so it is very important to pay more attention to the details of life and learn to clean underwear scientifically. Zhao, director of obstetrics and gynecology of PLA General Hospital, Zhu Lan, chief physician of gynecology of Peking Union Medical College Hospital, and Li, associate researcher of Tianjin Medical Research Institute, suggested that women should pay attention to five details when washing underwear.
1, change every day, don't accumulate.
Professional women are nervous at work and have heavy housework. In order to save time, many people buy back a dozen pairs of underwear at a time. They save it every day when they don't have time to wash it, and wash it together on weekends. "This is not desirable. Although underwear is changed every day, if it is not cleaned in time, the secretions on underwear will continue to breed bacteria at room temperature, and it will be more difficult to clean after a long time. " Li Jianyi's underwear must be washed the same day.
2. Rub the soap for 3-5 minutes.
Some women often rub their underwear in a hurry, sometimes even without soap. In this regard, Zhu Lan believes that underwear should be washed with soap, and two common pathogens in gynecology, mold and trichomonas, can be killed by the alkaline environment of soap solution. Zhu Lan reminded that ordinary soap can achieve this effect, and there is no need to use "underwear cleaning liquid" for cleaning. As for the scrubbing time, Li believes that it is best to scrub the soap carefully for 3-5 minutes after it is laid, so that bacteria can fully contact the soap.
3, rinse clean
After wiping, be sure to rinse thoroughly with running water and thoroughly wash the soap foam. Li explained that women's private parts are in an acidic environment, and secretions are also acidic, while soap is alkaline. When cleaning, acid-base contact generates salt. If you don't wash it in time, after a long time, underwear will harden, which is not conducive to health.
4. Don't wash with socks.
Some women are used to washing underwear, socks and autumn clothes with washing machines. In this regard, Zhao believes that underwear should definitely be washed separately. People's feet will breed a variety of germs such as mold. If socks and underwear are washed together, they may be contaminated with mold. In addition, family underwear should be washed separately, not together.
During the inflammatory period, underwear should be scalded with boiling water.
Zhao suggested that women with mold or trichomoniasis should wear cotton underwear. After washing, you should scald it with boiling water, or cook it directly, which can completely eliminate germs.
Step 5 dry in the sun
The drying of underwear is very important. Experts have emphasized that washed underwear must be dried in the sun. Ultraviolet rays can kill the bacteria on it, which is very beneficial to health. If you really can't get the sun, don't put it in a wet bathroom to dry. It should be hung on the balcony and other ventilated places to dry naturally.
