As early as 1958, an American newspaper said that "90% American youth wear jeans everywhere except in bed and church". Nowadays, jeans have become a classic clothing that is popular all over the world.
According to statistics, nearly 90% people in the world have at least one pair of jeans. Americans own eight pairs of jeans on average, and the number of young people is as high as 1 1. /kloc-young people aged 0/6-24 wear jeans more than four times a week on average.
According to the "2007 Global Cowboy Summit" held in Shanghai on June 165438+ 10/3, 2003, China people have an average of four pairs of jeans. A survey of 3,700 women shows that 45% women actually own 10 pairs of jeans.
However, it is this popular pair of jeans that has been questioned in terms of health. Ningxia Institute of Health Education recently published a "Reading Book of Health Education for Urban and Rural Residents", which is even called "Jeans Syndrome" to remind people to pay attention.
A few days ago, the Canadian Medical Journal reported that Dr. Palma of Ontario, Canada, believed that low-waisted tight jeans would squeeze the sciatic sensory nerve and cause abnormal tingling in the thigh skin.
Mott, a neuroscientist at the University of Kansas, said that he had seen more than 65,438+0,000 such cases in the past 20 years. "It's nothing serious. 95% people don't need treatment. As long as they put on loose pants, the symptoms will disappear on their own. "
In addition, tight jeans are also related to some gynecological diseases. Professor Zhu Lan from the Department of Obstetrics and Gynecology of Peking Union Medical College Hospital told the reporter that because jeans fabrics are airtight, it may make it difficult for women to excrete endocrine and cause gynecological diseases such as vulvitis and vaginitis. In addition, in midsummer, the metal buttons of jeans are in contact with the abdominal skin for a long time, which is easy to induce contact dermatitis.
For men, jeans are more "evil". Urology experts at the University of Iowa in the United States believe that wearing tight jeans may lead to a decrease in sperm count.
Yang Dazhong from the Department of Sexual Medicine in Tsinghua University told reporters that wearing tight jeans for a long time may lead to scrotal eczema. This is because the optimum temperature for testicular spermatogenesis is 35.5 to 36. Jeans tightly bind scrotum and testis, which reduces local heat dissipation, increases testicular temperature and hinders sperm production.
Of course, as long as you choose the right jeans and pay a little attention in your life, the above terrible diseases will not come to you easily. The first thing to consider is layout. The appropriate version should be placed on the back, and there is no discomfort in the whole body, but it is very close to the body. When trying it on, you can raise your knees to your chest after buttoning them to see if they are comfortable.
Secondly, the fabric. Jeans are elastic and breathable, so choose Caleb's. Elastic fabric fits the body and is more comfortable. Again, the model.
When trying it on, squat down and look at your back in the mirror. If most of your hips are exposed or there are more than three pieces of belly meat, it means that the waistband of jeans is too low or the size is too small. Finally, don't wear it often. You should prepare more loose cotton trousers.
In addition, experts also give people advice from the perspective of environmental protection: the latest research in France points out that each pair of jeans is made of 600g denim and 38g polyester, with 6 copper nails and 1 button.
If you use the washing machine to wash clothes, dry and iron every day, it is equivalent to wasting 240kW/h of energy every year, which is equivalent to lighting 4000 60-watt light bulbs. So the best way is to buy a pair of cotton jeans, then wear them for two days a week, wash them once every five days, and dry them naturally.
Some experts also point out that people buy too many clothes now, which wastes raw materials and causes global warming to some extent. Therefore, if we can control our desire to buy clothes, change the way we dress and rearrange our closets, we can make contributions to environmental protection.
