Is gold better than silver?
Silver is a precious metal jewelry loved by people. It can not only be used as jewelry of a single material, but also match with ring face and pendant to form jewelry inlay. At present, people are more and more favored to wear silver jewelry. Silver jewelry is not only beautiful and generous, but also economical and practical. The most important thing is that it will be good for the human body. Compared with gold and other precious metals, it has higher efficiency for human health.
1、 Release silver ions
Pure silver products can generate a magnetic field within a certain range and release silver ions according to the environment. This silver ion can stimulate energy. Therefore, wearing silver jewelry also has the effect of health care on the human body. The surface of silver plated jewelry, as well as jewelry with insufficient silver purity, will not have this effect.
2、 Suck out the damp and hot gas in the human body
People living in humid areas are prone to rheumatism. Close fitting silver jewelry can absorb damp and hot gas in the human body. Therefore, wearing silver jewelry for a long time can prevent or reduce rheumatism. The needle used in acupuncture and moxibustion of traditional Chinese medicine in China is a silver needle. Because bacteria are difficult to reproduce on silver needles, silver is known as "biological metal". Silver needles have no irritation to the human body, which can not be compared with any other metal.
3、 Adsorb lead on the human surface
Silver ornaments can absorb the lead attached to the surface of the human body. Silver water cups and tableware will absorb the lead in water and food. Long-term use of silver tableware can reduce lead intake and prevent chronic lead poisoning.
Silver ions have a particularly strong bactericidal ability. As long as each liter of water contains 2 milligrams of silver ions, it can kill most bacteria in the water.
Silver can inhibit almost all known bacteria and extracellular viruses, and will never produce any drug resistance. As early as a few years ago, there were all kinds of silver ion bactericides in the domestic and foreign markets. They not only have remarkable bactericidal effects, but also do no harm to the human body.
It is said that herdsmen on the grasslands of Inner Mongolia use silver bowls to hold horse milk wine, which will not turn sour after a few days. Similarly, holding water in a silver bowl can ensure that the water does not deteriorate. It is also said that some scientists have done experiments to treat sewage (including more than 7000 E. coli per ml) with a silver electrode for three hours, resulting in a large number of E. coli deaths. For example, skin ulcers can also be coated with a silver ion solution, which can kill most bacteria. In addition, it is said that many international airlines are using silver water filters. Some swimming pools also use silver to purify the water in the pool. The water purified by silver will not stimulate the swimmer's skin.
Although there are so many benefits of wearing silver jewelry, everything has two sides, and silver jewelry can't be perfect. It also has these disadvantages:
1. Silver jewelry is easy to react to with sulfur in the air and sweat. The black substance is generated, which makes the silver jewelry lose its original luster.
2. The higher the purity of silver jewelry, the softer it is, which is easy to cause certain scratches.
3. Based on the above two points, silver jewelry needs more time to maintain.
But compared with these shortcomings, the most afraid thing is to buy fake silver jewelry! You know what? Fake silver is equivalent to poison!
At present, because the price of silver jewelry is generally low, many consumers are not very concerned about the purity of silver jewelry, so they often buy fake and shoddy silver jewelry. Some consumers will buy silver jewelry for babies and the elderly, but the baby's skin is delicate and the elderly's skin immunity is low. Once they buy fake silver jewelry, it may cause harm to the body.
Experts said that inferior silver jewelry contains lead and chromium. Such heavy metals accumulate in the body for a long time, which will induce skin allergy, damage the heart, liver and even endanger life.
At present, the fake silver ornaments on the market are generally as follows:
1. Wrapping silver, wrapping silver on the surface of other metal products by mechanical or other methods to pretend to be silver jewelry.
2. Silver plating, the main material of this kind of jewelry, is generally an alloy material dominated by metals such as copper, but a layer of silver is plated on its surface to change its luster and make its shape similar to that of silver jewelry.
3. Although the surface layer of "sandwich" silver is also silver, its interior is other harmful metals, such as cadmium. Long term wear will affect the health of consumers.
When choosing silver jewelry, please try to choose products with brand and guarantee.
