According to a new study by Imperial College London, three fifths of British men are too lazy to change their underwear every day. According to the survey results of domestic medical experts, only about one fifth of them change their underwear every day. According to one statistic, men change their underwear only once every eight years. Whether the number is accurate or not, it's unbelievable.

How often do men change their underwear?

Men are more lazy, in the matter of changing underwear, but also lazy. Some male compatriots can wear a pair of underpants for a week. What's more, they carry forward the spirit of "new three years, old three years, sewing and mending three years" to the issue of changing underpants. So, how often should men change their underwear? How often do you change your underwear to help men's health?

In fact, men's underwear is better to wear one in the morning, take it off at night, clean it, and change into a new pair the next day. In this way, it is more reasonable.

In general, the underwear with a high frequency of use should be replaced after losing the old one in three months. However, it can not exceed half a year at most. Of course, during this period, if you find that the underwear is deformed, the material becomes dry and hard, and the stain is not clean, you have to replace it in time.

What should men pay attention to when choosing cleaning underwear?

1. Choose the color of underwear carefully. There are many men who want to look good, and they will buy underwear of various colors, even dark ones. Such a choice actually ignores the fact that colors are dyed by dyes. Dyes are a hodgepodge of a variety of chemicals, which contain some toxicity. As for the underwear that is too white, there may be some hidden dangers because of over bleaching, which increases the risk of associating with allergies.

2. Men should have at least 10 pairs of underpants. That is, one for each day, seven days a week, two for the weekend night, and one for emergency use.

3. Men who exercise a lot, often need to work outdoors, and men who sweat a lot need to prepare more spare underwear.

4. Underwear should be cleaned immediately after each wearing, even if it is only for one night. It is recommended that you change your underwear every day, especially in summer, and the maximum time should not exceed 2-3 days.

5. When cleaning, it should be separated from the outerwear, and hand wash with soap as much as possible.

6. After washing, don't directly expose to the sun, first put it in the shade to dry, then put it in the sun to disinfect, otherwise the underwear will be hard and deformed easily.

7. Underwear should be placed separately. You can buy some special storage bags, or put them in clean plastic bags to get dust and bacteria and affect your health.

8. Underpants should not be too tight (testes will be squeezed, high temperature will affect fertility), nor too loose (not enough support).

9. Flat angle underwear is suitable for all kinds of occasions. It can make men's private areas get enough support. But when they sleep at night, they need to change into loose four angle underwear to let them breathe. Also can choose four corner tight underwear, it can give the best support to the male privacy part, and it is suitable for all kinds of physical exercises.

A dirty underpants contains 0.1g bacteria on average, including Salmonella, Escherichia coli and other bacteria. Even if they are properly cleaned and dried, the bacteria on them cannot be completely killed. If you wash several dirty underpants at the same time, it may bring tens of millions of E.coli to the washing machine drum, and pollute other clothes through water quality, which may lead to congestion of the user's eyes, itching of the skin, dyspnea, etc.

11. Don't just wear pants instead of underwear. Although the wearer will feel his lower body is very loose, especially in the hot summer, many men only wear a loose beach pants outside, but it not only greatly improves the possibility of light, but also makes vulnerable parts more vulnerable to the friction of cloth.

12. Once the underpants have small holes, small cracks and slight wear, turn yellow and old, or send out peculiar smell, they should be thrown away immediately and replaced once every six months at most.
