Experts from the American "Men's Advice" website provide some guiding principles for men in choosing and wearing underwear:

Underwear should be updated in a timely manner. A statistic shows that men only change their underwear once every eight years. Regardless of whether this number is accurate, once there are holes, small cracks, minor wear, yellowing, oldness, or odor in the underwear, they should be replaced immediately. Throw it away and replace it every six months at most.

Men should have at least 10 pairs of underwear. That is, one for each day of the week, seven days a week, two extra on weekend nights, and one as emergency backup. Men who exercise more, often work outdoors, and men who sweat more need to prepare more spare underwear.

Choose underwear that suits you. Underwear should neither be too tight (the testicles will be squeezed and high temperatures will affect fertility), nor too loose (not enough support). Boxer briefs are suitable for wearing on various occasions. They can give men's private parts enough support, but when sleeping at night, they need to change into loose boxer briefs to allow them to breathe. You can also choose boxer briefs, which can provide the best support for male private parts and are suitable for various physical exercises.

Do not wash several items at the same time. Dirty underwear can carry small amounts of feces and cause disease. Underwear should be washed immediately after each wear, even if worn only for one night. Microbiologists from all over the world have studied washing machines and found that a pair of dirty underwear contains an average of 0.1 grams of bacteria, including Salmonella, E. coli and other germs. 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, you may bring tens of millions of E. coli to the washing machine drum and contaminate other clothes through water quality, which may cause bloodshot eyes, itchy skin, difficulty breathing, etc. in the user.

The other half should supervise and remind. Surveys show that single men are less willing to change their underwear than married men. Richard Cairns, a senior expert in consumer behavior analysis in the UK, said: "The underwear worn by lazy men will emit a unique unpleasant smell, and having a spouse will actively promote their habit of changing clothes. As a husband, men You will also keep the good habit of changing your underwear frequently.

In addition, don’t wear only outer pants without underwear. Although many people wear it in this way, their lower body will feel loose, especially in hot summer. Men only wear a pair of baggy beach shorts, but this not only greatly increases the possibility of exposure, but also makes vulnerable parts more susceptible to friction from the fabric.
