"ions" are charged particles. they are floating in the air around us all of the time and have either negative or positive charges. ions that are negatively charged are called "negative ions" or "anions". ions that are positively charged are called "positive ions" or "cations".  for example, oxygen occupies larger proportion in the air, resulting in formation of oxygen anions as the free electrons are captured by oxygen molecules. ions can be generated when a large amount of energy is applied to an atom or a molecule. negative ions are created in nature with air molecules broken apart by uv radiation from sunlight, cosmic radiation, radioactive substances, thunderstorm, waterfalls and sea waves.  negative ion has been recognized as "the vitamin of the air ", confirming its health effect on human, ionic research from leading institutions, along with worldwide clinical studies have proven its therapeutic effect. the concentration of negative ions in our living environment has been along observed to be correlated closely to the hunman health. negative ion also have been used as an important indicator for air and environment quality.   how is negative ion produced?   negative ions have been proven to have a positive impact on health, mood, and energy, affecting serotonin levels in the brain. negative ions also bond with impurities in the air, adhering to suspended particles and removing them.  how are they produced?  negative ions may be produced in several ways. the ions we are concerned with, oxygen ions, are most commonly produced through disturbance of water molecules, such as in fast flowing rivers or indoor waterfalls. the disturbance of water molecules occasionally displaces an electron, causing it to break off from its host. this spare electron then seeks out another oxygen molecule as a host, giving this molecule an extra electron, and therefore a negative charge.   3. benefit of negative ion correlation betwwen concentrations of negative ions in different environment and human health                   the number of anions in the air can impact on human health. if the air has too high a content of positive ions and too few anions, then 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 the body.  if the anion content of indoor air is raised to 1,500 per cc, it can improve the mood of those who stay in the room so that they can work better with higher efficiency. therefore, anion content is an essential factor for human 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 types of environment (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 healthcare have in recent years attracted extensive attention worldwide  in the air, tiny water molecules and oxygen molecules with negative electricity can combine to generate negative ions that can promote the metabolism when coming into human blood through lung.that's why people will feel better when they are in forest or close to waterfall. what factors does the concentration of negative ions in the air have relation with? in the natural air, the concentration of negative ions depends on the climate, geographical conditions and atmosphere pollutions, etc.   negative ion in the air is absolutely necessary to human being just like sunshine. the life of negative ion is very short, it's about a few minutes in clean air and only a few seconds in dirty environment or even shorter. in the open fields, seashores, country, water and spring areas its life can reach to more than 20 minutes, because in these areas the air pressure is smaller and the dust is fewer, so more negative ions can be generated from the air.  4. benefits for human body  negative ions are exceedingly beneficial for a person's metabolism as a means of enhancing human behavior. they act in a complex mechanism to bring about hormone and biochemical reactions in the body and brain. it is impossible to get an overdose of negative ions, which act like pure water in washing away dirty poisons. generally, the more negative ions you are exposed to, the better and more uplifted you feel.   the human body consists of billions of cells, and each is enclosed by a cell wall. this cell wall performs many necessary roles like absorbing nutrition and eliminatin
