Why do women's underwear turn yellow?

Women's underwear is the clothing that comes into closest contact with the private parts. In daily life, many women have encountered the phenomenon of yellowing underwear. Why do women's underwear turn yellow? There are many reasons why underwear turns yellow, which can be mainly divided into physiological and pathological reasons. In particular, some inflammations have such characteristics. We must have a comprehensive understanding of the general factors and make judgments based on our own situation. Let’s look at the main reasons below.

1. The problem with the material of the underwear. Nylon underwear has low sweat absorption ability, is not breathable, and has poor light resistance. It will easily turn yellow and age after being exposed to the sun for a long time.

2. Any cause that leads to increased blood bilirubin can cause an increase in the yellow pigment content in secretions and sweat, leaving yellow marks on underwear.

3. Most women will accidentally get menstrual blood on their crotch during menstruation. Underwear stained with menstrual blood is generally not easy to wash off, and there will always be a yellow mark left on the crotch.

4. Senile vaginitis is caused by a decrease in estrogen levels, which leads to thinning of the vaginal mucosa and increased secretions. Among them, yellow watery vaginal discharge can make underwear yellow. If the gynecological anti-cancer scraping is normal and there is no obvious discomfort, no treatment is required.

5. Urine contamination. The weakening of pelvic support tissue after menopause and unstable bladder function may lead to urinary incontinence. In addition, if women do not use paper towels to wipe their private parts after going to the toilet, urine residue will form in their underwear, and the underwear will gradually turn yellow.

1. During inflammation, underwear should be scalded with boiling water

Experts recommend that women with fungal or Trichomonas vaginitis wear cotton underwear. After washing, blanch it in boiling water or boil it directly to completely eliminate the germs.

2. Dry in the sun

Drying underwear in the sun is very important. Experts all emphasize that washed underwear must be dried in the sun. Ultraviolet rays can kill the germs on the underwear, which is very beneficial to health. If it really cannot be exposed to the sun, do not leave it in a humid bathroom to dry. It should be hung in a ventilated place such as a balcony to dry naturally.

3. Rinse thoroughly

After rubbing, be sure to rinse thoroughly in running water to wash off the soap bubbles thoroughly. The doctor explained that the female vagina is an acidic environment and the secretions are also acidic, while soap is alkaline. When washing, the acid and base come into contact to form salt. If it is not rinsed clean in time, the underwear will become hard over time, which is not good for health.

4. Don’t wash with socks

Some women are accustomed to mixing their underwear, socks, autumn clothes, etc. that they take off every day together and wash them in the washing machine. In this regard, experts believe that underwear should definitely be washed separately. Various germs, such as mold, can grow on human feet. If socks and underwear are washed together, the mold may be transferred to the underwear. In addition, the underwear of family members should be washed separately and not mixed together.

Working women have busy schedules and heavy housework. In order to save time, many of them buy more than a dozen pairs of underwear at a time. When they don’t have time to wash them every day, they save them up and wash them together on the weekend. This practice is not advisable. Although you change into new underwear every day, if you do not wash it in time, the secretions on the underwear will continue to breed bacteria at room temperature, and it will be more difficult to clean over time. Experts recommend that underwear should be changed and washed on the same day.
