What are the reasons why women's underwear turns yellow?

1. The material of the briefs itself is not good enough

There are many kinds of materials for briefs. Among them, nylon material has poor sweat-absorbing ability, and in addition to being non-breathable, it is also not light-resistant. When a woman cleans this kind of briefs and hangs them up to dry in the sun, they tend to turn yellow little by little and age continuously if they are left in the sun for a long time. Therefore, when buying briefs, you should ask what material they are made of, and try to avoid this material when purchasing.

2. A woman’s urine accidentally got on her briefs

Everyone knows that the urethra and vagina are very close, so after a woman urinates, if she does not wipe the excess urine with a clean paper towel, when she puts on briefs, the residual urine will be left in the crotch for a long time. If urine soaks into the material of the briefs, it will gradually turn yellow.

3. Women suffer from gynecological inflammation

After a woman suffers from inflammation, the secretions discharged from the private triangle area will become more abundant and yellow in color every day. Such secretions stick to the crotch of the briefs and will soak into the interior over time, causing the briefs to turn yellow.

4. When a woman comes to visit her aunt, her menstrual blood accidentally gets on her briefs

Many people don’t understand, menstrual blood is obviously red, why does menstrual blood cause briefs to turn yellow? This is mainly because it is always difficult to completely clean briefs stained with menstrual blood when cleaning the crotch. Over time, some residual menstrual blood gets into the material, making it even more difficult to wash off. Over time, yellow marks will appear on the crotch of the briefs.

How to wash women's underwear?

1. Hand washing is best

Some women find it troublesome to wash their underwear by hand and often use a washing machine to wash their underwear. This approach is not advisable because there are a lot of bacteria in the washing machine itself. It is easy to bring these bacteria to the underwear during cleaning, causing secondary pollution. At the same time, the washing machine It won't be as clean as washing it with your own hands. Washing by hand can more effectively increase the friction density, achieve the purpose of local cleaning more effectively, and wash the underwear cleaner.

2. Clean separately

Some women are accustomed to mixing the underwear, socks, autumn clothes, etc. that they change every day and washing them in the washing machine. If washed together with outerwear, it is easy to transfer external pathogenic bacteria and pollution sources to underwear. Socks, in particular, are prone to mold. If they are washed with underwear, the mold will be transmitted to the underwear. Mixing clothes in the washing machine can easily lead to cross-infection among members living together. For the health of yourself and your family, underwear must not be washed together.

3. Rub hard

When some women wash their underwear, they often rub it twice in a hurry, and sometimes they don't even use soap. It is recommended to use your thumb and index finger to pinch and rub carefully so that you can wash it more cleanly and thoroughly. The best time for scrubbing is to apply soap and rub carefully for 3-5 minutes to allow full contact between bacteria and soap.

How should women choose underwear?

1. Be sure to choose something that is comfortable to wear

Try to choose pure cotton underwear, because pure cotton underwear is not only comfortable to wear, but also very breathable, and it also has antibacterial effect? Especially for those with allergies, it is best not to choose underwear made of other materials than pure cotton. In particular, be careful not to choose chemical fiber or silk underwear, because underwear made of chemical fiber materials can easily generate static electricity and damage the skin. In addition, they are not good at permeability and are not conducive to the tissue metabolism of the vagina.

2. Breathability must be good

Only with good ventilation can the sweat and secretions secreted by women be evaporated in a timely manner to avoid being wet every day and causing bacterial infections.

3. The flexibility must be good

Good elasticity allows women to wear them more fitted, and secondly, it can avoid the feeling of being too tight, which affects their health. I would like to remind you that if possible, try not to choose thongs. Studies have found that people who often wear thongs Women are more likely to cause vulva friction and gynecological diseases. In addition, women's vaginal opening, urethral opening, and anus are all very close together. If it is too tight, it will easily cause frequent friction between various parts, and it is easy for bacteria in each part to infect each other. , causing diseases of the urinary system or reproductive system.
