Nano germanium, some companies introduce a metallic germanium solution with a particle size of about 20nm, but germanium is insoluble in water... Nano materials have almost no practical applications yet, and their safety It has not been confirmed by any authority. When doing carbon nanotube experiments, gas masks must be worn.
As for the health-care effects of biomagnetism, it is completely pseudoscience. The magnetic field generated by the human body is very small, on the order of 10^10 Tesla. In modern science, the effect of magnetic fields on the human body is still in the process of being studied, but there are research results from the outside world that can be put into practical use, which is a big joke in the world.
As for negative ions, they are negatively charged ions formed by the ionization of molecules in the air. Generally refers to negative oxygen ions and hydroxide ions.
The causes of negative ions in nature include ultraviolet rays, lightning, photosynthesis, etc.
(When humans confirmed that negative ions have an effective effect on people, in order to improve the environment and promote health, a large number of negative ion generators were invented, mainly using two methods, one is to use high-voltage electricity to generate ionization It makes the air produce negative ions. Another kind uses natural minerals and is processed by Keyuan. There are many materials on the earth that can release negative ions. They usually refer to energy stones, including various ores, seaweed sea stones and light shale containing protein. This material is processed into fine powder using high-tech technology, which is fully compatible with polymer materials. Many products can be developed and used in the textile industry, plastic products, paper products, etc. to form various negative ion functional products. These products release negative ions. The number can reach 1200-5000 per cubic centimeter, which is no less than that of humans in the natural environment of the countryside and fields.)
However, here, the negative ions released by these products are completely different from what we mentioned before. of negative oxygen ions! ! In fact, it does not have the same effect.
