Negative ion watch is a typical electronic watch. In addition to the normal time display function, the biggest difference is that the strap of this watch is a silicone strap with negative ion powder. The watch band is mainly made of imported environmentally friendly and healthy silica gel, which is composed of negative ion powder b] (tourmaline) and germanium powder, and has the health care functions of radiation protection, fatigue resistance and blood circulation promotion. According to the standard of similar high-quality products, the negative ion concentration reaches 1500-2200 ions /cc, which changes the negative ion content around an individual's body, thus generating a magnetic field and promoting human blood circulation. Long-term wearing can prevent ultraviolet radiation in the atmosphere, relieve fatigue and promote blood circulation.
2. Edit the main functions of negative ions
The main functions of negative ions: negative ions have sedative, hypnotic, analgesic, antitussive, antipruritic, diuretic, appetite stimulating and blood pressure lowering effects. For example, after a thunderstorm, negative ions in the air increase and people feel very comfortable. In an air-conditioned room, negative ions in the air almost disappear after a series of air-conditioning purification treatments and long ventilation pipes, and people will feel chest tightness, dizziness, fatigue, work efficiency and health level decline for a long time, which is called "air-conditioning syndrome".
What are negative ions?
The so-called negative ions refer to negatively charged particles. For example, positively charged particles in the air are called positive ions, and negatively charged particles are called negative ions. And ions refer to atoms floating in the air with electrons.
Experiments show that oxygen molecules in negatively charged air can combine with tiny water molecules to generate negative ions, which can enhance human metabolism after entering the blood through the lungs. This is why waterfalls and forests give people a refreshing feeling.
The importance of negative ions?
Ionized air exists widely in nature, and its existence constitutes a new discipline-electricity. Negative ion is an important part of ionized air, which plays an important role in human and biology. It is called vitamins and auxin in the air.
Influence of negative ions on human body
According to experts' observation and research, it mainly has the following functions: affecting the nervous system, strengthening the function and mental activity of the cerebral cortex, invigorating the spirit, improving work efficiency and improving sleep quality. Negative ions can also strengthen the oxidation process of brain tissue, so that brain tissue can get more oxygen. This is an effect on the cardiovascular system. According to scholars' observation, negative ions can obviously dilate blood vessels, relieve arterial vasospasm and achieve the purpose of lowering blood pressure. Negative ions are also beneficial to improve cardiac function and myocardial nutrition, and are beneficial to the rehabilitation of patients with hypertension and cardiovascular and cerebrovascular diseases. This is an effect on the blood system. Studies have confirmed that negative ions can slow blood, prolong coagulation time and increase oxygen content in blood, which is beneficial to the transportation, absorption and utilization of blood oxygen. Negative ions have the most obvious effect on the respiratory system. This is because negative ions enter the human body through the respiratory tract and can improve people's vital capacity. Some people have done experiments. Inhaling negative air ions in a glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 2%, while the amount of carbon dioxide discharged can increase by 14.5%, so negative air ions can improve and increase lung function.
Negative ions are the bane of cancer-causing active oxygen! Experiments show that negative ions are often used to freshen the air, and living in a room full of negative ions will make people feel happy. Professor Kenji Tanaka of Toyama Medical University in Japan and others found that negative ions can also increase antioxidants in the human body and reduce the harm of reactive oxygen species to the human body. According to a report in the evening issue of Yomiuri Shimbun on 24th, excessive reactive oxygen species in human body will damage protein cells, thus inducing cancer. Therefore, how to reduce the reactive oxygen species in the human body has always been a topic of concern to experts. Professor Tianze and others have done an experiment: installing an anion generator in a room, the number of anions per square centimeter can reach about 27 thousand in the area within 3 meters from the device, which is 27 times that of another room without the device. The researchers divided 1 1 athletes who did strenuous exercise and produced active oxygen in their bodies into two groups, let them sleep in these two rooms respectively, and then checked their blood and urine. The results showed that the antioxidant substance panthenol against reactive oxygen species increased by about 5 times and the substance promoting the regeneration of nucleus and cell membrane damaged by reactive oxygen species increased by 1/3. Researchers believe that negative ions can reduce or even resist the damage of reactive oxygen species to human cells.
5. A brief history of negative ion development
1.J .Thomson was the first to express the characteristics of ions by formula method, and at the same time established the model of positive and negative ions (negative oxygen ions);
Second, 1889, German scientists elster and Gaertel discovered the existence of negative air ions (negative oxygen ions);
Third, at the end of 19, German physicist Dr. Philip. Lionad first expounded the influence of negative oxygen ions on human body academically. He pointed out that negative oxygen ions in the natural environment are beneficial to human health, and pointed out that the place with the most negative oxygen ions is around the valley waterfall;
4. At the beginning of the 20th century, 1902 Asamas and others affirmed the biological significance of the existence of air ions through a large number of experiments;
5. 1903, Russian scholars first published a paper on the treatment of diseases with negative oxygen ions;
6. Langlin discovered the second ion in the atmosphere in 1905, which is called Langlin ion or large diameter charged particle, also called heavy ion;
7. 1909 A. Poole discovered the third ion, that is, the ion with medium diameter, which is called the middle ion;
8. In 1930s, Dissuader of Germany initiated the study of positive and negative ions (negative oxygen ions) in the atmosphere, which formed the first research climax of biological effects of negative ions (negative oxygen ions). Hundreds of papers, research and experimental reports have proved that negative ions (negative oxygen ions) have obvious beneficial effects on human body. Positive ions have obvious destructive effects on people's blood pressure and metabolism;
9. 1932, American RCA company Hamsen invented the world's first medical air negative ion (negative oxygen ion) generator, and these studies were terminated due to World War II;
It was not until the middle of the 20th century that Professor A.P.Kragan of the University of California and his research team began to conduct microscopic research and experiments on the biological effects of ions. The research of negative air ions (negative oxygen ions) has been pushed to the climax of secondary development and utilization. Professor Kragen has done a lot of experiments on animals, plants and people. It is found that negative oxygen ions can prolong the biological life 1/3. It also demonstrates how negative oxygen ions affect human body, animals and plants and produce various biological effects from the aspects of human endocrine, internal circulation and the reaction of various enzymes. Many researchers around the world have carried out the above experiments on the basis of their own research, and think that negative oxygen ions have obvious biological effects;
1978 an electronic instrument-biofilter, which is the predecessor of negative ion (negative oxygen ion) generator in China, was introduced by Dr. Shashawat of Iran.
12. 1985 In June, the Institute of High Energy Physics of Chinese Academy of Sciences and the Institute of Health Research of China Preventive Medicine Center developed a high-efficiency air negative ion (negative oxygen ion) generator, which was granted a patent with the patent number of 85202177;
13. In the 1980s, a group of experts and scholars from some domestic universities, research institutes and professional medical institutions began to set foot in negative ion (negative oxygen ion) medicine. They applied negative ion (negative oxygen ion) technology to clinic, and opened up a new way to treat diseases through exploratory treatment of various diseases. The Institute of High Energy Physics, Chinese Academy of Sciences, Xi Medical University, Beijing Research and Application Center for Air Negative Ions (Negative Oxygen Ions), Beijing Normal University and other scientific research institutions have carried out professional negative ion (negative oxygen ions) medical research, which has made remarkable achievements in negative ion (negative oxygen ions) medicine in China.
