Environmental protection function
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 incorporated negative ions into meteorological monitoring system, which has been widely used in air environmental protection and other fields. At present, meteorological departments in Zhejiang, Guangdong, Chongqing and other provinces have established an atmospheric negative ion observation network and an atmospheric negative ion meteorological forecast mechanism. Through the automatic air negative ion measurement system, the changes of negative ion concentration in different types of regions 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 all automated and intelligent, which provides a basis for building an eco-city environment. Air negative ions are known as "air vitamins" and are regarded as the first factor to support livable cities and livable communities. In 2009, Asia-Pacific Environmental Protection Association APEPA, China Urban Competitiveness Research Association and China West magazine jointly published "China City with High Negative Ions" in Hongkong and Chengdu respectively. Nearly 100 people from Chengdu news media such as Sichuan Academy of Social Sciences and Provincial Press and Publication Bureau attended the meeting. On 20 1 1 year, Xi World Expo will set up an exhibition hall in Bashang People's Area of the park to show the negative ion technology and human health, and establish a meteorological station of the Expo to monitor negative ions, analyze and track the air quality in the park.
air vitamin
Negative oxygen ions are called "air vitamins", which are beneficial to human physical and mental health. It mainly affects people's physiological activities through their nervous system and blood circulation. Negative oxygen ions can strengthen the inhibition process of human cerebral cortex and regulate 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 is relaxed and its spasm is relieved. When negative oxygen ions enter human blood, it can slow down erythrocyte sedimentation rate, prolong coagulation time, increase erythrocyte and blood calcium content, reduce leukocyte, blood calcium and blood sugar, and reduce lactic acid content 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.
Atmospheric vitamins
People will feel relaxed and happy as soon as they enter the park. In addition to broadening our 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 are negative oxygen ions. " Fan Jiping, vice president of Chinese Academy of Traditional Chinese Medicine and doctoral supervisor, introduced at the forum on environment and healthy development (Yichun) that places with high negative oxygen ion content are generally places with many long-lived elderly people, such as Changxing Island and hengsha island. But for city people, it is easy to take a few vitamin tablets, but it is difficult to breathe air rich in negative oxygen ions.
Wang, deputy director of the Economic Development Research Center of the State Forestry Administration, quoted a set of data as saying that the indoor concentration of negative oxygen ions in cities where people stay the most is 0/00 per cubic centimeter, and the concentration in building offices is even as low as 40-50 per cubic centimeter (according to the standards formulated by the World Health Organization, the content of negative oxygen ions in fresh air is not lower than 0/000-65438 per cubic centimeter of air). This air is often easy to induce headaches, insomnia and other discomfort. Many urban white-collar workers will feel dizzy after a day's work, which is related to the lack of "nutrition" in the air. The contents of "atmospheric vitamins" in forests, waterfalls, alpine coasts and parks are very rich, reaching respectively per cubic centimeter 10000 ~20000, 5000 ~ 10000 and 400 ~ 1000. Fan Jiping said: "Negative oxygen ions can promote human metabolism, prevent influenza and enhance human disease resistance."
People who live in cities for a long time should go outdoors as much as possible and go near places with running water and forests (especially coniferous forests such as pine trees) to supplement "atmospheric vitamins". I really don't have time, at least stay in the shopping mall near my home, because there can be 200 ~400 negative oxygen ions here, which is several times higher than that in the room.
Strengthen the oxidation process of brain tissue.
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.
treat a disease
(1), smoke and dust removal: negative ions can quickly neutralize coke smoke, "second-hand smoke", oil fume and floating dust in the air that belong to positive ions.
(2) Improve the air structure: people need 65.438+0.3 billion negative ions every day, but our living room, office and entertainment places can only provide about 200-200 million negative ions, which often leads to respiratory diseases such as pneumonia and tracheitis.
(3) Improve lung function: After inhaling negative ions for 30 minutes, the lung can increase the oxygen intake by 20% and expel 14.5% more carbon dioxide.
(4) Improve myocardial function: It has obvious antihypertensive effect and can make people feel refreshed. Improve work efficiency.
(5) Promote metabolism: Negative ions can activate various enzymes in the body, promote metabolism and improve sleep.
(6), enhance the body's disease resistance: negative ions can improve the body's responsiveness and enhance the body's disease resistance.
(7) Air negative ions can relieve or cure allergic hay fever, bronchial asthma and upper respiratory mucositis.
