Crazy! Why do girls' underwear turn yellow so easily?

I rubbed it with my hands every day, why did it turn yellow again?

Not only is it yellow, but you can see scabby secretions every day.

Is this normal?

Don't feel disgusted.

Even small underwear can reveal big problems↓

There is always yellow in the middle of my underwear, what’s going on?

Girls’ underwear is a little special. It encounters its old friend “leucorrhea” every day, and occasionally it will unexpectedly encounter “menstruation”.

Let's take a look at the ingredients of leucorrhea and menstruation:

"Leucorrhea" is mainly a mixture of vaginal mucosal exudate, cervical canal and endometrial gland secretions .

It's sticky and contains protein . Once it dries, it will form a scab and turn slightly yellow, which is normal , so don't worry too much!

There is no need to say much about menstruation. The blood also contains protein . If it is not washed clean, it will easily leave yellow marks on the underwear.

↓If you want to clean it, look here↓

√ Use cold water/warm water + wash in time

Here comes a piece of knowledge: When protein is exposed to heat or light, it will "denature and become inactivated ", and it will be more difficult to wash off if it sticks to your underwear!

If you wash your underwear in hot water, it's like boiling an egg . The protein itself is sticky, and when heated it solidifies and sticks to the fiber gaps of the clothes. No matter how hard you rub it, it's hard to clean it.

If you don't wash it in time, the light will slowly "denature and inactivate" the stains , firmly sticking to the underwear, and the longer it is, the tighter it will become. We should wash it as soon as possible.

The ultimate reason why underwear turns yellow is actually...

In addition to secretions that can turn underwear yellow, underwear itself cannot escape the fate of turning yellow ...

If you find that the whole underwear is a little yellow, or even a little hard, it means——

1️⃣This is a pair of underwear that has been worn for too long

The lifespan of underwear is not long. Under normal circumstances, they should be changed and washed every day and replaced every 3-6 months .

In addition, Yue Miaojun would like to remind you: sweat stains are also protein stains . If you always wear synthetic underwear , it is more likely to cause sweating and the underwear will turn yellow.

So when buying underwear, we should also pay attention to the fabric.

2️⃣ Don’t change or wash your clothes frequently

Stop hoarding dirty underwear!

The study found that there is at least 0.1 grams of feces on a pair of underwear, and up to 10 grams

Inadvertently, urine and feces can also turn your underwear yellow . If you don't wash them frequently, stubborn stains will merge with your underwear and it will be difficult to avoid turning them yellow.

When your underwear has changed color and cannot be washed out , even if it is only a little bit yellow, it's time to throw it away.

Otherwise, bacteria and mold are likely to grow, so be careful of inflammation.
