The most stable situation for a negative ion is when the very small size of moisture in the atmosphere (water cluster) attaches electrons.
That means if the air was extremely dry, you could not expect negative ions to be there.
However, if it was raining heavily, the water became positive-ionized big particles.
To stabilize negative ions in the atmosphere, it is ideal to keep the humidity between 40 to 60 %. A typical example of a fully negative-ionized environment would be inside a forest or near a waterfall. Both are endowed with moderate humidity.
?The rain in the forest is sucked up from the roots of plants and evaporates from the pores of the leaves. Wind tears up the water cluster, dividing it into the positive and negative-ionized particles.
The soil in the forest becomes cushy sponge-like dirt due to mulching and uncountable holes by the micro-organism, and after absorbing rain, if it was a nice weather, it produces both negative and positive ions.
Then, while the bigger particles would immediately fall to the ground, the smaller ones get carried away further like bubbles and create a negative-ionized environment.
Depending on the area, but in general windy weather, makes water particles in the atmosphere break more easily, there are 5,000 to 6,000 negative ionized particles.
In a place like this, the proportion of negative ions and positive ions is four to one, extensively more negative ions than positive ions.
On the other hand, in the forest like around Mount Fuji or a jungle where the humidity is more than 80 %, there are more positive ions speeding the rate of decay.
Ten to 300m away from the basin of a waterfall there are 3,000 to 5,000 negative ions, five times more than their positive counterparts.
It is often said that there are more negative ions at a waterfall, but research shows that if closer than ten meters, there are more positive ions.
That is because while the big positive-ionized water clusters immediately falls on the ground, the small negative ?ionized water clusters have the tendency to get carried away by the wind as bubbles do.
The reason why you feel good in a place like this, it is not only the mental effect of being surrounded by green.
Absorbing a fair amount of negative ions helps the body to be alkalescent, to save electrons within the cells and (TAIEKI) working to activate each cell, and those results in refreshing the body and the mind.
There are plenty of negative ions in nature, which explains why people always working in a greener environment with cleaner air unintentionally have a more stable mood and positive attitude.
It should be clear why the negative ion is called “the energizing ion”.
