Air is a mixture of many gases, the main components of which are nitrogen, oxygen, carbon dioxide and water vapor. Normally, the various gas molecules in the air are stable and neutral, i.e., they are not electrically charged. However, due to natural cosmic rays, ultraviolet rays, as well as lightning, wind and waves, plants, etc., they can cause the surrounding air to ionize and produce negative ions, also called negative air ions. Negative air ions are essentially negatively charged air particles. The negative air ions that people usually refer to are negative oxygen ions, which are formed when oxygen molecules in the air combine free electrons. The natural discharge (lightning) phenomenon, photoelectric effect, combustion process, fountains, waves, waterfalls, etc. can make the surrounding air ionization, the formation of positive and negative ions.
2. What are the factors related to the amount of negative ions in the air?
In the natural air, the amount of negative ions and climate, geographic conditions and atmospheric pollution, etc., it is determined that: 6-,September, the highest concentration of negative ions, 1-3 months is the lowest, the rest of the month is between the two.
On the earth's surface, the negative ion concentration is generally a few thousand / cubic centimeter. Big city theater, only 10-30 / cubic centimeters, big city room is generally 40-50 / cubic centimeters, the street green area for 100-200 / cubic centimeters, the park for 400-600 / cubic centimeters, the suburbs up to 700-1000 / cubic centimeters, and in the seaside, valley, waterfalls, etc. can be as high as 20,000 / cubic centimeters or more.
3. How much negative air ions on the human body what effect?
Negative air ions, like vitamins in food, have a very important impact on human life activities, so also known as air vitamins. It can promote human growth and development and prevent a variety of diseases, mainly in:
(1) On the respiratory system: improve lung function. Inhalation of negative ions after 30 minutes, the lungs absorb 20% more oxygen, carbon dioxide exclusion increased by about 14.5%.
(2) To the cardiovascular system: it has obvious antihypertensive effect, improves myocardial function, increases myocardial nutrition, expands peripheral capillaries, and increases skin temperature.
(3)To the nervous system: it can make people refreshed, improve sleep, and has obvious sedative and analgesic effects.
(4)To metabolism: it can activate many kinds of enzymes in the organism, and after absorbing negative ions, it can reduce blood sugar, cholesterol, increase blood calcium, urine volume, nitrogen and creatinine in the urine, accelerate the growth of bones, and prevent scurvy, rickets and vitamin deficiency.
(5) For blood: it can increase white blood cells, red blood cells, hemoglobin, reticulocytes and platelets, slow down blood sedimentation, increase globulin, increase PH, and shorten blood clotting time.
(6) On immune ability: it can improve the reactivity of the body, activate the function of reticuloendothelial system, and increase the body's ability to resist diseases.
4. What are the applications of negative air ionization in healthcare?
Commonly, negative air ions are inhaled to treat respiratory diseases. Overseas 1300 cases of bronchial asthma patients, after the responsible system of ion therapy, control of the attack of 55% of patients, the condition of 35% reduction, no effect of 10%.
Some respiratory infectious diseases, negative ions also have a good therapeutic effect. Such as children's whooping cough, 25% of the patients, treatment 3-5 times can heal, some patients have to 10-15 times to heal.
Chronic rhinitis, chronic pharyngitis, each inhalation of 20,-30 times, has a good therapeutic effect.
Air negative ion treatment of diseases and: neurosis, insomnia, migraine, hypertension, dysmenorrhea, menstrual dermatitis, trauma, burns, etc..
Negative ions are non-toxic and have no side effects. Generally speaking, it is ideal to use negative air ions as an adjunctive treatment.
5. What is a negative ion generator?
Negative air ions, like sunlight, are essential human substances. However, negative ions have a very short lifespan, only a few minutes in clean air, and only a few seconds, or even less, in a dirty environment.
In the wilderness, seaside, mountain villages, waterfalls, fountains and other places, due to low atmospheric pressure, less dust, high temperature, the air ionized negative ions, their life expectancy can reach more than 20 minutes; in the city, especially in industrial and mining areas, densely populated, chimney stacks, smoke and soot, and automobile emissions, the air is contaminated, the number of negative ions is greatly reduced, disrupting the ecological balance, the people's health is threatened.
The natural phenomenon of revelation, people began to use artificial methods to generate negative ions, released into the surrounding air, purify the air, improve people's living environment. This artificial generation of negative air ions in the device is called negative air ion generator or negative ion generator.
