According to a survey conducted by the Daily Mail, people often make these mistakes when wearing underwear: choosing the wrong material, the underwear is too loose or too tight, the style is inappropriate, it is not often changed, and a pair of underwear is worn for several years.
Life Times invites authoritative experts to tell you what a perfect pair of underwear looks like.

In the choice of color, generally speaking, light-colored underwear is better.
The Daily Mail pointed out that the risk of black underwear in particular is relatively high. Dark underwear uses more dyes and contains chemicals similar to "hodgepodge", which is more likely to cause contact allergies.
Women had better wear white cotton underwear. If you have gynecological diseases and abnormal secretions, you can see them at a glance. Other colors of underwear or patterns are too flowery, which may affect everyone's judgment on leucorrhea.
Some women like lace material and should choose pure cotton crotch when buying.
In fact, no matter what color underwear you buy, it is recommended to buy a reputable brand. Be sure to wash it before wearing it after buying it, so as to reduce the damage of chemical components to the skin.
Pure cotton is the healthiest material for both men and women.
In addition to pure cotton, modal underwear has good water absorption and breathability, and it is also very comfortable to wear.
The data shows that modal absorbs and releases water 50% faster than ordinary cotton, but people with sensitive skin may be allergic.
Underwear made of chemical fiber may rub the vulva skin, causing inflammation, allergy and itching.
It is suggested that underwear made of silk, lycra, nylon and chemical fiber (pure polyester) be removed from the wardrobe.
Man: Boxer pants.
Boxer underwear can provide a relatively suitable temperature for testicles and ensure the quality of sperm.
In 20 12, scientists from the University of Sheffield in England found that the sperm concentration of men wearing tight underwear was lower than that of men wearing boxer shorts.
There are also many kinds of boxers. In addition to the appropriate size, it is recommended to choose closed underwear, which is slightly one or two inches lower than the crotch.
Female: briefs
Women should choose briefs with good air permeability.
Women should wear less thongs, which are easy to hurt delicate skin, make blood circulation poor, lead to bacteria invading urethra and reproductive tract, and cause inflammation.
The elderly should choose high-waisted underwear with a height above the navel, which has a good warm effect.
Many people think that underwear, like clothes, can be worn for several years, especially for the elderly, who often throw it away when it is worn out and deformed.
Microbiologists all over the world have studied washing machines. A pair of dirty underwear contains an average of 0. 1 g of feces, which contains bacteria such as salmonella and Escherichia coli. Even if it is cleaned and dried correctly, it can't completely kill the bacteria on it.
Men and women, underwear should be replaced after 3~6 months. To prevent deformation, dry and hard materials, dirt, etc. , should be replaced in time.
Many people are used to putting their underwear in a pot for a few days, and then washing them after saving enough, or even wearing a pair of underwear for two or three days.
This will turn underwear into a "bacterial nest", which is more difficult to clean.
If you wear underwear that is not thoroughly cleaned, it will not only aggravate skin itching, but also easily cause bacterial and fungal infections. So, don't stay overnight, clean your underwear immediately.
Special tips
Special people are very picky about the choice of underwear;
Inadequate cleaning of underwear will bring diseases. If the cleaning method is wrong, even if it is changed every day, it may not be really clean.
Some people are used to washing underwear with washing machine, which will bring bacteria from washing machine to underwear.
There is only one best way: wash your hands. Hand washing can increase friction density, help local cleaning and make it cleaner.
1, a special soap
It is recommended to choose a special underwear cleaning soap, which is different from the soap used for ordinary clothes.
2. Knead for 3~5 minutes
Soak the soap in warm water, then soak the underwear in it and rub it gently. Crucial parts should be pinched with forefinger and thumb, carefully rubbed for 3~5 minutes, and finally rinsed with flowing water.
If your underwear is stained with menstrual blood, you can wash it with cold water first. If the blood stain is dry and hard, it can be decomposed with hydrogen peroxide.
Don't mix with other clothes.
If mixed with the coat, it is easy to infect the underwear with external germs and pollutants.
Socks, in particular, are prone to mildew. If mixed with underwear, it will be contaminated with mold.
The basin for washing underwear should be dedicated to avoid cross-infection.
4, bask in the sun for half an hour
Ultraviolet rays in sunlight can kill bacteria. You can put your underwear in the afternoon sun for half an hour, but don't dry it inside.
If there is no drying condition, try to dry it in a ventilated place, or directly treat it at high temperature, iron it with an electric iron or blow dry it with a hair dryer.
