Silver is one of the most popular precious metals nowadays, and there are a number of reasons why it tops the list of preferences of millions of women and men around the world. The aesthetic shapes it takes after processing as well as its affordable price are the most obvious, but only a few of them. Not so well known are all the properties that silver possesses, and our goal today is to introduce you to the most important of them. For example, did you know that silver is one of the few active antimicrobial metals? If you're also one of those silver jewellery lovers, continue reading to find out what other positives they bring, besides being a flawless finishing touch to any look.
The antimicrobial properties of silver
You may be aware that similar antibacterial and antimicrobial properties can be found in metals such as copper and brass, but scientific studies prove that they are not the only ones. Silver also has the ability to fight microorganisms and bacteria that could be harmful to the human body. The antiseptic processes of silver were discovered by a Swiss botanist around the end of the 19th century, when he noticed how silver ions attacked the microorganisms they made contact with. A team of scientists from the University of Arkansas decided to study in detail the effects of silver ions on bacteria and their activity, using an extremely high-quality technique to image this process. They found that just a few minutes after contact with the ions, bacteria and other microorganisms died and no longer posed a threat to the body. In addition to their effective protection against parasites, silver ions aid in the healing processes of the body.
A number of research activities are aimed at creating new and better antibiotics based on silver nanoparticles. Other experiments have shown that if we put a silver particle into the culture medium of a particular bacterial culture, the bacteria there are also killed. This antiseptic action of silver is the reason why it has a great application in pharmaceutics. It is used to make many preparations that are used in medicine.
The benefits of silver in fighting COVID-19
Over the past almost two years, public authorities globally have taken drastic measures to strengthen public health as well as mitigate the socio-economic impact in response to the COVID-19 pandemic, also known as the "coronavirus". Wondering how silver could be of use in such a situation? While companies for the various modes of public transport around the world are considering which is the best option for disinfection, the Tokyo subway authority is using the antimicrobial properties of silver. The Japanese capital's subways are among the busiest in the world. It consists of 85 lines, around 900 stops and nearly 3,000 trains, which are sprayed with a spray containing a silver solution. Officials say antimicrobial compounds have been proven effective against viruses, which is why they decided to take this innovative approach.
"Standard carriage disinfection has a short-lasting effect, which is why we sought an antimicrobial application to reassure passengers that our trains are safe." Masaru Sugiyama tells Reuters.
Natural external regulator of heat and circulation in the body
Have you heard that silver can help regulate our body temperature? By coming into direct contact with our skin, it has the ability to improve our internal heat regulation. This property of it can be extremely beneficial, especially during the hot summer months when we are constantly battling the heat. In addition, silver also plays a role in blood circulation within the body. It helps to supply oxygen and other important substances to all the extremities of the body. The reason for this are its thermal and electrical conductivities.
Interesting use of silver jewelry
For thousands of years, silver jewelry has been used as protection against infection in many different cultures. In addition to the healing properties that were attributed to silver in ancient times, people also believed that it had magical ones. It is considered a precious metal that is directly linked to the cult of the moon and the feminine. Based on this, it was believed that a woman who wore silver jewelry received a new source to recharge her feminine energy. Another interesting thesis is that the precious metal can even boost your immune system, protecting you from flu and colds. This is due to the positively charged ions that bind to the negatively charged surface of bacterial cages and neutralize them. Although not scientifically proven at this time, a large number of people also share a sense of relaxation, increased energy and mood after prolonged wear of the silver jewellery.
