Practicability of titanium ring

Liar, don't buy a titanium collar: Yang Wei is a little annoyed recently! Girlfriend's birthday is coming? Yang Wei doesn't know what kind of birthday present he can give. I have been in contact with my girlfriend for 6 years and have already sent flowers, chocolates, electronic products and other conventional items. Last year, because there was no good choice, the gift I gave failed to please beautiful women. Just when Yang Wei was at a loss about this gift, he was excited by a suggestion from his friend Song Jia. It turns out that Song Jia told him that a product containing titanium-titanium ring or titanium ring-is popular in many places now. Wearing this product is not only beautiful, but also has health care function, which can relieve muscle fatigue. Yang Wei was overjoyed: What gift is more irresistible than health and beauty now? Is titanium's function of environmental protection and health really that powerful? Under the guidance of a friend, Yang Wei came to the titanium ring sales counter of a shopping mall in Hangzhou, Zhejiang Province, and saw various titanium ring collars hanging in front of the display cabinet, as well as titanium ring bracelets, titanium ring belts and titanium ring insoles. From the price tag of these expensive titanium rings, Yang Wei saw that a titanium ring costs more than 300 yuan, the cheapest titanium ring is near 200 yuan, and the expensive one costs more than 1000 yuan. When the salesman saw Yang Wei wandering around the counter, he immediately told him enthusiastically that the titanium ring has a good health care function, which can treat cervical spondylosis, relieve fatigue and relieve muscle pressure, especially for people who sit in front of the computer for a long time. Yang Wei found that the words on the outer packaging of the titanium ring were all in foreign languages, and there was a label translated into Chinese, and the word "titanium" was not marked in the composition. The salesperson explained: "The titanium in the titanium ring is embedded in the plant fiber, and it is a titanium product processed by a special process, so the composition is not indicated." Seeing Yang Wei with a grain of salt, the sales staff enthusiastically suggested that a small experiment could be done to feel the effect of "titanium ring". Then, she conveniently took out a kettle full of water from the counter and asked Yang Wei to stretch out his arm to carry water. After the first lift of water, the salesperson tied two titanium rings to Yang Wei's hand and asked him to lift the kettle again. "Is it easier to carry water for the second time than for the first time? In principle, the second time should be easier than the first time. " The salesperson said with a smile. After listening to the salesperson, Yang Wei recalled: "It seems that the last time was really easier than the last time." "It is right to feel this way." The shop assistant followed Yang Wei's words. In a Korean titanium ring counter, the shopping guide told Yang Wei that many customers patronize their counter every day, and most of them are recommended by friends for consultation and purchase. At the same time, the shopping guide said: "Titanium ring products are made of tourmaline and titanium germanium mixed silica gel, which can emit negative ions and far infrared rays beneficial to human health. Tourmaline is famous for its ability to release the highest level of negative ions in many minerals to maintain health. Titanium and germanium are considered as ideal partners for maintaining oxygen supply, which can emit negative ions and far infrared rays beneficial to human health. Most customers buy for this reason. " In order to let Yang Wei have a more direct understanding, the shopping guide tested the product with a negative ion content detector: the titanium ring just taken out of the container showed that there were 358 negative ions in the air per cubic centimeter, while the titanium ring just put on by the shopping guide contained 1475 negative ions in the air per cubic centimeter. In this regard, the shopping guide explained that the product must be in contact with the human body to emit more negative ions. The psychological effect is greater than the actual effect. "Titanium ring products are health care products or decorations? Is its effect really so magical? " Doubts swirled in Yang Wei's mind, making him undecided whether to buy this gift for his girlfriend or not. So, he decided to go online first to see the curative effect after others used it. Enter the keyword "titanium ring" in a website, click to enter, and a lot of discussion about titanium ring products will pop up on the webpage. There are basically two opinions on the evaluation of titanium ring: some people hold a positive attitude towards titanium ring and think its effect is good. A netizen named "Big Apple" wrote in his blog: "Recently, there is a kind of' Dongdong' circulating in the office, called titanium ring, which is a new thing from Japan. Kelly is a patient with severe cervical spondylosis. Her sister brought her one from Shanghai last year. She said that her cervical spine would be fine after wearing it. I usually have a little pain in my cervical spine and want to buy myself a titanium ring. " Some netizens hold a negative attitude and think that there is no practical effect, and the seller just grasps the psychological effect of the customer. A netizen named "Mercury in Tears" posted: "I was going to buy it, but later I saw an expert on TV specially made a program about titanium rings, saying it was psychological, but it was not used." After reading the comments of netizens, Yang Wei finally decided to give up buying titanium rings. "I learned about titanium rings from online forums. The netizens played very well. Just because I didn't sleep well, I bought one with a try. " Mr. Zhang, a Beijing citizen, seems to be less determined than Yang Wei. "When I first put it on, the effect was not bad and it was easy to fall asleep." So, Mr. Zhang immediately introduced this thing to those who are in the same boat around him. "But in a few days, my sleep returned to its original state." Mr. Zhang said gloomily, "I'm not sure whether this thing will work or not." There is a letter, but there is no letter. "Finally, Mr. Zhang summed up his feelings after using titanium rings with ambiguous answers. Ms. Wu is a full-time wife. She spends more than 8 hours on the mahjong table almost every day, and her cervical vertebrae and lumbar vertebrae are sore. Ms. Wu's daughter is clever and sensible, and gave her mother a titanium ring as a New Year gift. Since then, Ms. Wu's "Ma You" seems to have been infected, and many of them have been bought and worn. " It's better to use it than to use it. There are no side effects anyway. I don't feel anything special after wearing it, but it may be worse without it. Everyone can't say for sure about this thing, but it feels good. "Ms. Wu commented on her daughter's gift. In the interview, the reporter found that when users of titanium rings introduce the effects of products, the words that appear most frequently are: maybe, probably, it feels like … "In the field of scientific research in China, there is no evidence that titanium has a direct health care effect on human body. "Wang Jian, a professor at the Department of Physical Education of Zhejiang University and director of the Institute of Sports Science and Technology of Zhejiang University, believes that the" magical effect "of titanium rings circulating in the market is purely a psychological function of consumers and a psychological sustenance of consumers. Due to the people's thirst for health and the relative lack of medical information, this phenomenon of blind obedience has appeared. Experts believe that the academic circles have never mentioned that "titanium collar can relieve cervical spondylosis", saying that "titanium-containing products can treat cervical vertebrae, relieve fatigue and help sleep" and there is no medical literature to support it. Even if titanium products can really regulate human current, the effect is minimal. The classification of health care products is still inconclusive. Not only ordinary people are keen on titanium rings, titanium rings and other products, but also some movie stars and sports stars seem to be loyal supporters of this product. I saw many big-name stars on TV, such as Liu Xiang, Dānlín, nakata hidetoshi and Tian Liang ... Sports stars have great appeal, and their every move has a great influence on us. Moreover, it is said that such necklaces and bracelets can relieve muscle aches, promote blood circulation and eliminate fatigue. "A heptathlete who bought a titanium bracelet commented on the titanium ring. A person in charge of the Shanghai Sports Bureau said in a telephone interview: "I have never heard that athletes wearing titanium rings are helpful for training. If Liu Xiang wears a titanium ring, it should have nothing to do with training and performance. "Professor Wang Jian said that it is understandable to sell titanium rings as ordinary decorations, but as a health care product, especially with therapeutic effects, he believes that there is no scientific basis. An orthopedic expert surnamed Li in beijing jishuitan hospital said that cervical spondylosis is caused by the injury and degeneration of the joints, intervertebral discs and surrounding soft tissues of the cervical spine, which leads to the stimulation of the cervical nerve roots. At present, the reasonable methods to treat cervical spondylosis include cervical traction physiotherapy, acupuncture and massage, medicine and surgical treatment. To prevent cervical spondylosis, it is necessary to change the long-term bad working posture. " Titanium is commonly used in medicine to make steel nails, steel plates and other tools for fixing bones in plastic surgery. If titanium can relieve fatigue and muscle stress, people who have undergone orthopedic surgery cannot directly experience this effect. But this is not the case. "Professor Li said. At the same time, a professor in the chemistry department of Lanzhou University also pointed out: "Titanium is not a radioactive substance. If titanium is added to other metals, the metal structure can be changed, but it has never been heard that titanium has health care function. "It is reported that there is no relevant standard to define the quality of titanium products in China at present, and there is no relevant testing standard. Whether this kind of products belong to health care products has not been recognized authoritatively in China.
