What is the effect of negative oxygen ions on the human body?

Air negative oxygen ion is a negative charge of air particles, it is like the vitamin in food, has a very important impact on human life activities, so some people call it "air vitamin", some even think that the air negative oxygen ion and longevity, called it "longevity factor ".

In nature, the atmosphere ion although invisible, but people can feel the presence of negative oxygen ions. Nature in the air positive and negative oxygen ions is in ultraviolet light, cosmic rays, radioactive substances, lightning, storms, waterfalls, waves impact generated, both constantly generated, and constantly disappear, maintaining a certain dynamic equilibrium state. At the same time, because the ground for the formation of atmospheric ionosphere electrostatic field, the ground for the negative pole, the result of negative air oxygen ions by the ground repulsion, positive air ions are attracted by the ground, so, in general, the ground surface positive ions more than negative ions, positive and negative ion concentration ratio is often greater than 1, the concentration of 400 ~ 700 / cm3 or so.

Mountain forests, tree crowns, the tip of the leaf end of the discharge, and lightning, waterfalls, waves, the impact of the formation of higher concentrations of small air negative ions, so that the air is fresh and refreshing. And densely populated metropolis, industrial pollution areas, closed air conditioning room, the resulting pollutants and pollutants of liquid, solid and various organisms and air formed aerosols, so that a large number of small air ions combined into large ions and sink, lose activity, so that the small air negative ion concentration is reduced, and positive and negative oxygen Ions very unbalanced state, and people feel uncomfortable, and even dizziness, headache, nausea, vomiting, emotional distress.

Respiratory difficulties, reduced work efficiency, resulting in some symptoms of unknown pathology. Similarly, the level of negative ion concentration is closely related to people's health, people always need negative ions, especially in today's increasingly serious pollution.

According to environmentalist research, the concentration of negative oxygen ions in the air per cubic centimeter in the following 20, people will feel tired, dizzy; when the number of negative oxygen ions per cubic centimeter of air in the 1000-10000 between, people will feel calm, calm and stable; when the number of negative oxygen ions per cubic centimeter of air in the 10000 above, people will feel refreshed, comfortable and comfortable; And when the number of negative oxygen ions per cubic centimeter of air up to 100,000 or more, it can play a sedative, asthma, eliminate fatigue, regulate nerves and other preventive and curative effects. Therefore, many attractions use negative oxygen ion detector to monitor its concentration.
