Many people say that wearing silver ornaments is good for your health. According to research, silver does have a little more health benefits than other metals. However, many people will say that the reason why silver ornaments wear for a long time is due to poor health. Is there any scientific basis for this statement?
1. All silver is a silvery white metal with good ductility and the highest conductivity and thermal conductivity of all metals. Because of this characteristic, silver can quickly dissipate the heat of blood vessels, can quickly reduce the body's heat, is conducive to the prevention of various diseases.
2. At a very early time, people knew that silver had the effect of sterilization and disinfection, which could accelerate the healing of wounds, and could also be antiseptic and fresh-keeping. Common antibiotics only work on a few viruses, but silver ions can kill hundreds of bacteria.
Silver has a great effect, so wearing silver is good for your body. But some people say that if you wear silver jewelry, if you are not in good health, silver will easily turn black. Is there any scientific basis for this?
What is the reason for the discoloration of silver ornaments?
1. Silver has a better ability to absorb toxicity, so it will discolor the surface. However, this is only a superficial phenomenon, which can be eliminated with toothpaste or special drugs.
2. The silver ornaments of pure silver are also easy to be oxidized, react with sulfur, and then turn black, and sulfur exists in many places. So it's easy for silver jewelry to react when it's worn on the hand. Different times will also show different colors, not because of the toxins in the body.
3. According to experts, there is no necessary connection between silver blackening and health.
Some people's silver jewelry will be brighter and brighter, because some substance secreted by the skin when the human body perspires has a protective effect on the silver, and there is no sulfur element in the sweat, so it doesn't react much.
If some people wear silver ornaments, the more black they wear, it may be that the sulfur content in their sweat is relatively high, which is easy to react with silver jewelry and make silver jewelry black. However, this does not mean that they are not healthy.
4. In addition to the reaction with sulfur, the blackening of silver ornaments is also related to the pH value of human body. If the sweat is acidic, the higher the acidity, the faster the silverware will turn black.
Therefore, the reason why the silver ornaments become black is that the body is not healthy. There is no scientific basis for it. Don't believe it blindly. There are also some things that will turn black when they encounter silver. For example:
1. Eggs.
Cook the eggs and cut them in half. Then put the silver on the eggs. After five minutes, the silver will turn black, like a fire.
2. Kiwi fruit.
Cut the silver into two and a half layers, and you'll find that there's a black substance on the top.
3. Water.
Usually do not take a bath or swim with food, easy to turn black, do not bring silver jewelry with other metal objects, so as not to scratch silver ornaments and make silver blacker.
