With the improvement of people's material living standards, the sleep economy has also quietly emerged. All kinds of healthy mattresses emerge in an endless stream, all under the banner of high-tech ergonomics and the name of hospital experts of health associations. This kind of mattress is often expensive, often tens of thousands. The experience store was opened near the community, with free experience+family offensive+curative effect publicity, and a must-buy mattress was born in the mouth of the store clerk. Generally speaking, the experience stores of this kind of health care products are located near the community, and so-called health talks are held regularly, and many elderly customers come to experience them regularly every day. The staff in the store are warm and friendly. There seems to be nothing unusual in the store, but they have various functions in their mouths, such as regulating endocrine, improving sleep, promoting microcirculation, and also having special effects on cerebrovascular diseases, arteriosclerosis and other diseases. A customer service staff selling jade mattresses in Beijing told the author that jade mattresses are mainly aimed at middle-aged and elderly people and can alleviate and improve the chronic diseases of the elderly. As for the main functions of the jade mattress, he gave the author a link to Baidu Encyclopedia, indicating that the basic functions of the jade mattress are similar. Indeed, the propaganda slogans posted by jade mattress dealers on their websites are similar, and collectively moved out of the records in Compendium of Materia Medica to prove the medicinal efficacy of jade; It is emphasized that jade contains a variety of trace elements, and long-term contact can supplement the missing trace elements in the human body, so that various physiological activities in the human body can be carried out more normally. Emerald absorbs light during the day and glows at night. If its light spot is aimed at a certain acupoint on the human body, it will stimulate the meridians like acupuncture. Moreover, jade mattress also has certain preventive and health care effects on hypertension and arteriosclerosis, and can even tonify kidney and strengthen yang, nourish yin and nourish blood after long-term use. Is it furniture or medical equipment? If the jade mattress has all these functions, is it furniture or medical equipment? The customer service staff told the author that their products belong to the national second-class medical devices and can be inquired online. Immediately, he sent the author a certificate of quality management system certification of jade mattress through the network. However, the certificate only shows that the jade electric mattress and electric mattress of this mattress product factory meet the ISO900 1 standard. Under the author's questioning, the customer service staff changed their minds and said: our national second-class medical device license is being processed. Then ended the conversation with the author. According to China's "Measures for the Administration of Medical Device Registration", an enterprise applying for medical device registration shall obtain a license for medical device manufacturing enterprise, and its product range includes products applying for registration. Xiuyan Yushi Mattress Products Factory, a manufacturer of jade mattresses, has not obtained the license of the manufacturer, let alone applied for the second-class medical device license. After searching the official website of the US Food and Drug Administration under the category of medical devices with jade as the key word, the author found that the only jade bed that can be searched is a warm physiotherapy instrument produced by a medical device company in Guangzhou. Its products are suitable for the auxiliary treatment of lumbar muscle strain, lumbar disc herniation, shoulder and back myofascitis, lumbar facet joint disorder and cervical spondylosis, which is far from the curative effect of the jade bed advertised on the Internet. As for other kinds of jade mattresses, none can be found. The health care effect is more likely to be psychological. Bao Deqing, an associate professor at the Jewelry College of China Geo University, told the author that Xu Shen of the Han Dynasty once said that the beauty of jade has five virtues; The strict definition of jade is given, and the difference between jade and stone is explained in detail. Modern people regard almost all beautiful stones as jade, and the concept is already very confusing. For example, Xiuyu in Liaoning is only jade in a broad sense, and white marble is just fine-grained marble. Used to make health mattresses on the market? Jade? Most of them are these two kinds, no different from stones. What about medical care? Merchants claim that jade can reduce oxygen consumption in blood and strengthen human metabolism; It can emit far-infrared electromagnetic waves absorbed by human body, and even nourish stomach, strengthen yang, nourish yin and nourish blood. In response to these propaganda words, Professor Bao said that there is no scientific basis. However, jade may indeed contain trace elements. When jade comes into contact with human body, it may exchange elements with human body when the temperature changes, but this is only speculation. He believes that the health care function of jade is more psychological. If you believe, there will be, if you don't believe, there will be. Even though jade is rich in trace elements, can people absorb these elements when they come into contact with jade? Xú Zhēng, a professor at West China College of Pharmacy, Sichuan University, explained that from a pharmacological point of view, drugs can only play a role if they are absorbed into the body. Topical transdermal preparations or traditional plasters can also be absorbed by the human body. But skin contact is not enough to absorb mineral elements just by wearing it. There is no experimental basis for saying that this mineral is absorbed or excreted through the skin.
