What are Anions?
Posted on July 26, 2007
All living things in the world are related to anions (or negative ions). Take a moment to learn about anions.
Under normal circumstances, the air molecules or atoms are neutral. Natural ionization caused by cosmic rays, ultraviolet rays, micro radiation, lightning and thunder etc, cause some air molecules to lose an electron that is orbiting around the nucleus and this free electron with a negative charge will combine with other neutral air molecules to make them negatively charged. These are negative ions in the air. They are colorless, odorless and have strong absorption capability to absorb micro particles in the air to remove dust and bacteria. Anions in the air are as important as vitamins in the food and are given such nice names as vitamins of the air, longevity element, air scavenger and others.
Anions have special significance to human health which should not be underestimated. They can have extraordinary absorption capability to gather dust particles, bacteria and viruses which are normally of positive charge and neutralize them. Anions enter the cells of the bacteria to kill it off. More anions in the air would mean fewer bacteria and when the concentration of anions reaches a certain level, the number of bacteria can be reduced to zero.
The number of anions in a cubic centimeter (cc) of air is 40 to 50 in the urban residential area, 100 to 200 above the urban area, 700 to 1,000 in the field and more than 5,000 in the valley. The number of anions in the air can have a big impact on human health. If the air has too high a content of positive ions and too few anions, the human body may develop symptoms such as fatigue, dizziness, migraine, depression and shortness of breath, but these could be rapidly relieved if air with 1,200 anions per cc is taken in by the body. If the anion content of indoor air is raised to 1,500 per cc, it can improve the mood of those in the room allowing them to work with higher efficiency. The negative ion / anion content of the air in which we live has a direct relationship to our health and longevity.
The World Health Organization (WHO) has specified that the anion content in the air should not be lower than 1,000 per cc. In certain environments (such as the mountainous area), the inhabitants are free from troubles of inflammation and generally live longer. This is obviously related to the fact that the air there contains abundant anions.
The positive effects of anions in the field of medical health care have in recent years attracted extensive attention worldwide.
