The lack of negative ions can cause headache, uneasiness or sudden nausea. People often experience these common problems in an overcrowded room or in an air-conditioned room. Never ever worry about the name, scientists found that there is no negative effect about negative ions. It’s positive ions to be harmful to human body. In contrast, negative ions are beneficial for human’s health.
In the air, there are many invisible charged particles called ions – either molecules or atoms. Some particles bring positively charge while others bring negative charge. More specifically, positive ions are molecules or atoms that have lost one or more electrons whereas negative ions are actual oxygen atoms with extra electrons.
So where can we find negative ions? We can find the highest concentrations of negative ions in natural and clean air. In nature, negative ions are abundant, and we can find them at many places, such as areas around waterfalls, on the ocean surf, at the beach and after a storm. Especially, negative ions are widespread in mountains and forests. Unfortunately, few people live in those areas. Most people live in polluted cities, crowded areas and in confined spaces such as offices, industrial areas, schools and cars, where you will find the highest concentration of unhealthy positive ions.
Negative ions can be found in the air we breathe in and they can also be found in our bodies. The fact about negative ions’ benefits to our overall well-being and health is scientifically proven:
* Negative ions neutralize free radicals which are harmful to our health.
* Negative ions revitalize cell metabolism.
* They enhance immune function, hence help us to prevent many health problems.
* They purify the blood.
* They balance the autonomic nervous system, promoting deep sleep and healthy digestion.
The most important benefit of negative ions is their ability to clear the air of health threats such as bacteria and viruses. Furthermore, they also clear the air of dust, pet dander and cigarette smoke. Negative ions perform this fantastic function by attaching themselves to positively charged particles in large numbers and negatively charging those particles. As a result, these viruses and bacteria become too heavy to remain hovering and are no longer able to enter our breathing passage where they can make us fall sick. For this reason, negative ions are believed to form a protective circle around our body.
