1. Environmental protection

The concentration of negative ions in the air is one of the signs of air quality, and the World Health Organization has also stipulated the standard concentration of negative ions in fresh air. China has also brought negative ions into meteorological monitoring system, which has been widely used in air environmental protection and other fields. Meteorological departments in Zhejiang, Guangdong, Chongqing and other provinces and regions in China have established atmospheric negative ion observation networks and atmospheric negative ion meteorological forecasting mechanisms.

through the automatic air negative ion measurement system, the changes of negative ion concentration in the atmosphere in different types of areas are monitored, and the distribution characteristics of negative ion concentration in different time and space scales, different underlying surfaces, different weather processes and different seasons are studied, so that the collection, transmission, processing and release of negative ion concentration data in the atmosphere are fully automatic and intelligent, which provides a basis for building an eco-city environment.

2. Air vitamins

Negative oxygen ions known as "air vitamins" are beneficial to human physical and mental health. It mainly affects human physiological activities through human nervous system and blood circulation. Negative oxygen ions can strengthen the inhibition process of human cerebral cortex and adjust the function of cerebral cortex, so they can play a role in sedation, hypnosis and blood pressure reduction;

After negative oxygen ions enter the human respiratory tract, the bronchial smooth muscle relaxes and relieves its spasm. When negative oxygen ions enter human blood, it can slow down the sedimentation rate of red blood cells, prolong the coagulation time, increase the content of red blood cells and blood calcium, decrease white blood cells, blood calcium and blood sugar, and reduce the content of lactic acid in tired muscles.

negative oxygen ions can strengthen the oxidation process of human kidney, liver, brain and other tissues, among which brain tissue is the most sensitive to negative oxygen ions.

3. Atmospheric vitamins

As soon as people enter the park, they will feel relaxed and happy. Apart from broadening their horizons, a very important reason is that the air here is fresh and rich in negative oxygen ions. "Everyone knows that vitamins are very important to the human body. In fact, there are vitamins in the air, which is negative oxygen ions." The places with high content of negative oxygen ions are generally places where there are many long-lived elderly people, such as Changxing Island and hengsha island.

4. Strengthen the oxidation process of brain tissue

Negative oxygen ions can effectively increase red blood cells, obviously improve children's brain working ability and prevent fatigue, which is of great significance for children to improve their hearing, IQ and emotional stability. Experiments show that negative oxygen ions can effectively improve the level of intelligence and physical strength. Negative oxygen ions can increase the content of zinc in the brain and promote the synthesis of protein in the brain, thus improving learning and memory.

5. Beauty effect of negative oxygen ions

Kitchen fumes, air dust, bedding mites and electromagnetic radiation are the main factors that damage women's skin. Women's long-term exposure to these harmful substances will cause skin diseases of different degrees, which will not only lead to aging, dark yellow, pigmentation, chloasma, acne and other skin problems.

The use of a large number of chemical skin care products has a certain effect, but at the same time, the side effects are more harmful to the health of women's skin, which leads to more fragile facial skin tissues and affects skin elasticity. Negative ions can inhibit the consumption of vitamin C and actively produce new collagen.

Supplementing enough negative ions can rejuvenate the collagen in the dermis, restore the original elasticity and moisture of the skin, rejuvenate the epidermis, develop vigorous metabolism again, solve skin problems, and achieve the effect of beauty and skin care.

Generation principle of negative ions

1. The atmosphere is ionized by ultraviolet rays, cosmic rays, radioactive substances, thunderstorms, storms, soil and air radiation, and the released electrons are absorbed by the earth, and then released quickly and combined with neutral molecules in the air to become negative ions, or called anions.

negative ions in nature (that is, negative ions that play a good role and reduce in the body) have great antioxidant effect and reducing power.

2. Waterfall impact? Water flows at a high speed under the action of gravity in natural processes such as small waves pushing and rolling heavy rain falling, and water molecules crack to produce negative ions. The process of molecular morphological transformation of matter.

3. The forest trees, the photoelectric effect formed by the tip discharge of leaves and branches and the photosynthesis of green plants ionize the air and generate negative ions.

4. Some crustal rocks can release some negative ions.

5. Air negative ions are generated by artificial negative ion generation technology. According to media reports such as Xinhuanet and Guangming Daily, the latest negative ion converter technology and ecological negative ion technology with pollutant collection function have produced negative ions that have reached ecological level, that is, negative ions with small particle size that are easy to enter the human body.
