Speaking of people’s most private and close-fitting clothing, it is undoubtedly underwear. Don't underestimate this little "piece of cloth". Its material, quality, and comfort are all very particular. Wearing suitable underwear when you start a day of study or work will make you feel much better.

But at the same time, underwear, as our close-fitting clothing, carries a lot of burdens. It is known as "the dirtiest clothing on the human body". So, how dirty can underwear be? We might as well find out.

How dirty can underwear be? Let’s take a look at the experimental results

" Chinese Journal of Mycology " once published an experiment in which a pair of normally worn underwear was brought to the laboratory to test the ingredients:

In addition to regular sweat stains , in addition to dead skin cells, feces are the main source of "dirty" underwear. Many friends may feel "embarrassed". As the clothing that is most closely in contact with our buttocks, it is normal for it to carry feces in a tight environment for a long time. There is no need to be too shy.

Speaking of research, according to statistics , a pair of personal underwear carries an average of about 100 mg of excrement . Although it still sounds "cold", this is indeed a common fact. Especially for those who don’t change their underwear frequently, the degree of dirt on their underwear will be higher. If things go on like this, bacteria and dirt will come into contact with the skin of the lower body, and the risk of infection and inflammatory diseases will be higher.

It can be seen from this that the underwear we usually wear should be far more dirty than most people imagine. But because of the different genders of men and women, most people subconsciously think that men's underwear is dirtier than women's underwear. Is this true?

Men VS women, whose underwear is "dirtier"?

If under the same sanitary conditions , In fact, women’s underwear is “dirtier” than men’s.

Professor Charles from the University of Arizona in the United States once led a comparison of the reproduction rates of bacteria on the body surfaces of men and women.

The results found that the bacterial reproduction rate on women’s body surfaces is actually faster than that of men, even dozens of times higher. In addition, women’s urethra is open and is more likely to become a breeding ground for bacteria. Therefore, women’s underwear has a higher degree of bacterial reproduction than men’s.

Not only that, women also have a special part every month, that is, the menstrual period, such as leucorrhea, menstrual blood, etc., more or less some will be stained on their underwear, and these secretions also carry a large number of bacteria. .

It can be seen from this that women’s underwear is actually dirtier. But generally speaking, men do not clean as frequently as women, so in fact, as long as underwear is a "concentration place" for dirt, regardless of gender. More importantly, you must learn to clean and change underwear to ensure that you are clean and tidy.

Underwear is so dirty, how often should I change it? How can I wash it cleaner?

If it is a daily change, changing it once a day is a better choice. If your underwear accidentally stains obvious stains or metabolites remain, don't hesitate to replace them in time.

If it is a "new for old" replacement, the decision depends on the condition of the underwear:

Underwear meets these three points, it is recommended to replace it with new one:

① The underwear is obviously damaged

When the underwear is damaged, many People may find it troublesome, but wearing it inside will make it easy. Many boys, especially, have had similar experiences.

However, damaged underwear means that some areas that should be protected are not protected. Outer pants are in direct contact with the body, which makes it easier for bacteria to breed.

② Yellow and hard underwear

Yellow and hard underwear means that bacterial growth has penetrated into the fiber At this time, even if you wash it hard, the cleaning effect is not too obvious. The underwear at this time can be thrown away. Wearing yellow and hard underwear for a long time will increase the probability of bacterial infection and is not good for health.

③ Wearing obviously uncomfortable underwear

The basic principle of underwear is to be comfortable. If you wear uncomfortable underwear, an environment that is too compact and airtight will aggravate the growth of bacteria . And it may cause skin damage due to excessive friction. It is detrimental to both health and comfort and needs to be replaced in time.

The cleaning of underwear is also divided into two schools:

"Hand washing school" and "Machine washing school".

In fact, hand washing is more recommended. After all, underwear is personal clothing. We must try our best to ensure that it is clean before putting it on to effectively reduce the risk of bacterial infection. There may be some hair, debris and other dirt hidden in the washing machine. If you use the machine for a long time, it will not be clean. It is a better choice to wash your underwear by hand, wash it carefully, and the bacteria isolation rate is high.

In summary, I believe everyone has a new understanding of underwear. Whether it is changing or cleaning, many people may maintain their own habits. You may wish to adjust them as a reference. Perhaps there will be considerable improvement in terms of personal neatness and hygiene. . The foundation of health will be more solid.
