If you don't change your underwear for a month, if a woman suffers from precancerous lesions, how many days should she change her underwear? how long to wear

Zhang Qian (pseudonym) has just graduated from university and shares a rent with a few girls. Due to the limited sanitation conditions, Zhang Qian herself is rather lazy. She often only changes her underwear once a month, and her underwear only once a few weeks .

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

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

This shows how important it is to keep underwear clean, so how often should underwear be washed? Did people not wear underwear before?

1. Before there was no underwear, what did people wear?

When you go out, you don't need to wear a hat or coat, but you must not lose your underwear. But in the beginning, underwear didn't even exist.

The so-called "fig leaf" first appeared in ancient China in the Han Dynasty. It was called Dubishi , and its shape was a curved triangle, similar to modern briefs. It was usually worn by farmers, servants or soldiers for the convenience of movement.

But the rich people in ancient times thought that the calf-nosed coat was the stuff of the poor. In order to show their noble status, the rich wore the hakama . There are two types of hakama. Similar to modern trousers, but with an open crotch.

Seeing here, do you feel that this is still very different from the briefs we wear in modern times.

Indeed, briefs are influenced by Western culture. In 1935, the famous underwear manufacturer Jockey sold the first pair of briefs in Chicago, and the real briefs finally appeared . Nowadays, whether it is briefs, boxers, boxers... Underpants have evolved into "variety".

2. Do you need to change and wash your underwear after wearing them for a few days?

Although it is just a piece of cloth, it can block the dirt and stimulation from the outside world, and can also reduce the friction between the genitals, vulva skin and outer pants.

However, a pair of underwear is "avoidable" to the inside. A small piece of 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 dirty.

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

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

1. Knead for 3-5 minutes

Some people wash their underwear, they always run it in hot water, then apply soap, and rub it a little bit, some don't even use soap, just flush 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 can fully 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 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, so as not to harden the underwear easily, which is not conducive to health.

3. Dry in the sun

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

What needs to be reminded is that underwear also has a "lifespan", generally 3-6 months, and the time is relatively flexible. When you find that the underwear has turned yellow, hardened, or deformed, it means that the underwear has aged and it is time to change it .

3. Can panties and socks be washed together?

For lazy people, underwear, panties and socks are the best "one pot", and some people say that socks are so smelly, it feels disgusting to wash them with underwear.

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

The peculiar smell 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 does not mean that they are harmful. Most of them are colonized bacteria on the body surface. Even if they are transferred to the skin, it is difficult to reproduce in large numbers.

However, there is one situation that needs vigilance, that is, beriberi patients.

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

Therefore , if the underwear and socks are mixed, there is a risk of cross-infection . If you use the traditional laundry method, using a mallet, you can't completely wash away the microorganisms, and some bacteria will remain on the clothes. Secondly, even if you use soap, washing powder, etc. to decontaminate, some bacteria are more resistant and usually need to be cleaned. Warm water above 60°C or even 90°C can kill it.

If you use a washing machine for machine washing, since the washing machine has its own hot water and drying function , most microorganisms on the body surface will perish if it exceeds 36°C. After washing the underwear, use the drying function to create a clean high-temperature environment and fully sterilize. For patients with beriberi, bleach can also be added during the process to kill the fungus.

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

4. How to choose the underwear that suits you best?

Underwear is the most intimate clothing for private parts. It is closely related to health. Different groups of people should focus on different choices of underwear:

·man

Pure cotton is preferred, with good air permeability and good water absorption . The underwear should not be too tight, otherwise it will increase the friction between the legs and "cover" the testicles. Studies have found that tight underwear reduces sperm motility in men compared to boxer briefs .

·woman

Like men, pure cotton is the best material for women's underwear, and modal material can also be used in summer, which has high water absorption and air permeability.

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

·elder

The elderly do not sweat a lot, but considering that they have been sitting or lying down for a long time, and their underwear is not changed frequently, it is recommended to buy silk fabrics and use pure cotton as the bottom for key parts.

Underwear for the elderly is suitable for high-waisted pants to help protect the abdomen. For the elderly with poor blood circulation, it is best to choose boxer briefs to avoid the briefs strangling the thighs.

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 an underwear washing machine or using qualified disposable underwear. Underpants, otherwise, change and wash them obediently.
