If a woman does not change her underwear for a month, if a woman suffers from precancerous lesions, should she change her underwear every few days? how long to wear

Zhang Qian (pseudonym) has just graduated from college and is sharing an apartment with several girls. Due to the limited sanitary conditions, Zhang Qian is also lazy. She often changes her underwear only once a month , and only once a few weeks . Even when her menstrual period comes, she just needs to put some paper on it.

Last month , Zhang Qian found a faint feeling of discomfort in her lower abdomen. Because she often stayed up late, smoked, and ate late-night snacks, her life was irregular. She thought that her period was coming, so she didn't care. until ten days later,Zhang Qian was so in pain that she couldn't get out of bed . Seeing this, her roommate quickly dialed 120 and sent her to the hospital for emergency examination.

After a preliminary examination, the doctor found that Zhang Qian 's vulva had vegetations , and further tests confirmed that it was a precancerous lesion of the vulva . According to Zhang Qian 's daily habits, the doctor is likely to be caused by some kind of virus. Because she often does not change her underwear, and her work and rest are irregular, the chance of infection is increased.

This shows how important it is to keep your underwear clean, so how often should you wash your underwear? Before there were no panties, did people not wear them?

1. What did people wear before they didn't have underwear?

When you go out, you may not wear a hat or a jacket, but you must not be short of underwear. But in the beginning, panties didn't exist at all.

The so-called "fig cloth" first appeared in ancient China in the Han Dynasty .

However, in ancient times, the rich thought that the dubi was the stuff of the poor. In order to show their noble status, the rich wore hakama . There are two kinds of hakama. Close to modern pants, but with an open crotch.

Seeing this, do you think that this is still very different from the briefs we wear today.

Indeed, briefs are influenced by Western culture. In 1935, the famous underwear manufacturer Jockey sold the first briefs in Chicago, and the real briefs finally appeared . Today, whether it is briefs, boxer pants, boxer pants... Underwear has evolved into "variety".

Second, the underwear should be changed and washed for a few days?

Don't look at it as just a piece of cloth, but it can block external dirt and irritation, and can also reduce the friction between the genitals, vulva skin and outer pants.

However, a pair of underwear "cannot be avoided" inside. A small piece of fabric in the underwear is likely to be contaminated with urine, feces, genital secretions, sweat, etc., and may even be parasitic with various germs. It can be said that the underwear is really very dirty.

A study analysis found that an average pair of underwear will carry 0.1 grams of feces . If the replaced underwear is not cleaned in time, under unfavorable environment, it is likely to multiply in large numbers and become a "bacteria based pants".

So it is best not to wash underwear overnight , so how to properly wash underwear?

1. Knead for 3-5 minutes

Some people wash their underwear, they always run it with hot water, then apply soap and knead it a little, and some don't even use soap, just rinse it with water.

If you want the soap to work, it is best to rub it carefully for 3-5 minutes, so that the bacteria and the soap are in full contact.The alkaline environment of the soap can kill mold and trichomoniasis.

2. Rinse with running water

In order to save water, some people like to use a small basin to wash their underwear, change the water before soaping, and change the water after soaping. It is best to use running water to wash underwear, and rinse the soap thoroughly to prevent the underwear from becoming hard, which is not conducive to health.

3. Dry in the sun

It is very important to dry underwear. Under full sunlight, ultraviolet rays can help eliminate some germs. If there is insufficient sunlight in the drying place, try to put it in a ventilated and dry place. Do not put it in a damp bathroom, as it is conducive to the growth of bacteria.

It should be reminded that underwear also has a "life", generally 3-6 months, and the time is relatively flexible. When the underwear is found to be yellow, hard and deformed, it means that the underwear has aged and it is time to change .

3. Can panties and socks be washed together?

For the lazy family, underwear, panties and socks are best "in a pot". Some people also said that socks are so smelly that they feel disgusting when they are washed together with their underwear.

First of all, what are the bacteria on the socks?

The odor of socks mainly comes from the large amount of sweat secreted by the feet. After sweating, the products will be decomposed by bacteria , resulting in the smell. But the bacteria on the feet do not mean harmful, most of which are colonized bacteria on the body surface , even if transferred to the skin, it is difficult to multiply.

However, there is a situation that needs to be vigilant, that is, patients with beriberi.

According to statistics, a sock of athlete's foot patients may have more than 100,000 fungi . If these pathogenic fungi are mixed with underwear, it is easy to cause athlete's foot transfer, which can cause femoral moss and itching all over the body. In the event of a severe foot fungal infection, the propagules of the fungus may also be passed on to towels, slippers, and bed sheets.

Therefore , if the panties and socks are mixed, there is a risk of cross infection . If the traditional laundry method is used with mallet clothes, the microorganisms cannot be completely washed away, and some bacteria will remain on the clothes. Secondly, even if soap, washing powder, etc. are used for strong decontamination, some bacteria are more resistant, usually need to Warm water above 60°C or even 90°C can kill it.

If you use a washing machine for machine washing, because the washing machine has its own hot water and drying functions , most of the microorganisms on the body surface will perish when it exceeds 36 °C. After the underwear is washed, using the drying function can create a clean high temperature environment and play a full sterilization effect. For patients with beriberi, bleach solution can also be added to kill the fungus during the process.

If you can't accept it psychologically, then wash it separately.

Fourth, how to choose the most suitable underwear?

Underwear is the most intimate clothing in the private area. It is closely related to health. Different groups of people should focus on different selection of underwear:

·man

Pure cotton is preferred, underwear with good air permeability and good water absorption , it is best not to be too tight, otherwise the friction between the legs will increase, and it will also "cover" the testicles. A study found that, compared to boxer briefs, tight underwear reduced the activity of men's sperm.

·woman

Like men, the material of women's underwear is also preferably pure cotton. In summer, modal can also be selected, which has high water absorption and breathability.

Women's vaginal opening, urethral opening, and anus are relatively close, and underwear is not suitable for wearing too tight, otherwise it is easy to rub and cross infection. Women's underwear should be light-colored as much as possible , which can facilitate the observation of women's vaginal health.

·elder

Because the elderly do not sweat much, but consider their long-term sedentary or long-term lying, and the underwear is not changed frequently, it is recommended to choose silk fabrics, and use pure cotton bottoms for key parts.

The elderly's underwear is suitable for high-waisted pants to help protect the abdomen and the elderly with poor blood circulation. It is best to choose boxer underwear to avoid the bottom of the thigh.

Summary: Although the underwear is close to the body, it is actually not very "clean". Therefore, both men and women should change and wash their underwear every day from the perspective of health. If you are really lazy, you can also consider buying a underwear washing machine to do it for you, or use a qualified disposable Underpants, or else you should change and wash them obediently.
