Look how dirty this thing is

According to a new study by Imperial College London, three-fifths of British men are too lazy to change their underwear every day. The results of a survey by domestic medical experts also show that only about one-fifth of people change their underwear every day. Medical experts say: Men's laziness in changing underwear is a serious threat to men's health, and this is how men's health hazards arise. In this regard, experts provide men with some guiding principles in choosing and wearing underwear:

Underwear should be updated in time

A statistic shows that men only change their underwear once every eight years. Regardless of whether this number is accurate, once the underwear has small holes, small cracks, slight wear and tear, turns yellow and old, or emits a strange smell, it should be thrown away immediately and replaced at the latest every six months.

Men should have at least 10 pairs of underwear

That means one pair for each day of the week, two extra pairs for weekend nights, and one more pair for emergency use. Men who exercise more, often need to work outdoors, and sweat more need to prepare more spare underwear.

Choose the underwear that suits you. The underwear should not be too tight (the testicles will be squeezed and high temperature will affect fertility) nor too loose (not enough support). Boxer briefs are suitable for wearing in various occasions, and they can provide sufficient support for men's private parts, but when sleeping at night, you need to change into loose boxer briefs to allow them to breathe. You can also choose boxer tights, which can provide the best support for men's private parts and are suitable for various sports exercises.

Don't wash several at the same time

Dirty underwear will carry a small amount of feces and cause disease. Underwear should be washed immediately after each wear, even if it is only worn for one night. Microbiologists from all over the world have conducted research on washing machines. A pair of dirty underwear carries an average of 0.1 grams of bacteria, including salmonella, E. coli and other pathogens. Even if it is washed and dried correctly, the bacteria on it cannot be completely killed. If you wash multiple pairs of dirty underwear at the same time, it may bring tens of millions of E. coli into the drum of the washing machine and contaminate other clothes through the water quality, which may cause the user's eyes to be congested, skin itching, breathing difficulties, etc.

The other half should urge and remind

The survey shows that single men are less willing to change their underwear than married men. Richard Cairns, a senior expert in British consumer behavior analysis, said: "The underwear worn by lazy men will give off a unique unpleasant odor. Having a spouse will play a positive role in promoting their habit of changing clothes. Men who are husbands will maintain the good habit of changing their underwear frequently."

In addition, do not wear only outer pants without underwear. Although people wearing this way will feel that their lower body is very loose, especially in the hot summer, many men only wear a pair of loose beach pants outside, but it not only greatly increases the possibility of exposure, but also makes vulnerable parts more susceptible to friction from the fabric.
