Negative ions themselves have excellent effects of purifying and removing dust, reducing the harm of second-hand smoke, improving the prevention of respiratory diseases, improving sleep, resisting oxidation, preventing aging, scavenging free radicals in the body, reducing blood viscosity, etc., and enjoy the reputation of "vitamin", "air vitamin" and "air vitamin" in the medical field.

However, the negative ion magnet pillow currently sold in the market is only a conceptual product, because negative ions can not be detected at all and can not be generated. First of all, we need to know how negative ions are produced. Among them, the three mechanisms of negative ions in nature are: 1. The atmosphere is ionized by ultraviolet rays, cosmic rays, radioactive substances, thunderstorms, storms, soil and air radiation, and the released electrons quickly combine with neutral molecules in the air to become negative ions, or called negative ions. 2. In the natural process, water flows at high speed under the action of gravity, such as waterfall impact, small waves pushing, rainstorm falling, and water molecules cracking to produce negative ions. 3. The photoelectric effect formed by the tip discharge of forest trees, leaves and branches and the photosynthesis of green plants ionizes the air and produces negative ions. Therefore, where there are mountains, water and trees, the concentration of negative ions will be even stronger.

Artificial generation of negative ions requires a negative ion generator, which generates negative ions and then releases them into the air through a releaser. The book Environmental Health and Negative Oxygen Ions written by Professor Lin Jinming, a doctor in Tsinghua University, defines that air negative ions can be divided into large, medium and small ions according to their mobility, and only small ions or small ion groups can enter the living body. Small negative oxygen ions or small negative oxygen ion groups have good biological activity. Small ions are small particle size negative ions, which are equivalent to air negative ions in nature. Some data call them ecological negative ions, which have the characteristics of long migration distance and high activity. At present, only by adopting the world-leading ecological negative ion generation chip technology and nano-fullerene negative ion releaser technology can we generate ecological small particle negative ions equivalent to nature.
