Yesterday somebody was telling how rain affects us - our mood, energy level, spirit... - since it brings negative ions. And of course, and excess of these causes different effects on people too, most usually feeling downhearted or overactive or in rage.
According to a quick research this is because:
"Inside every cell there are more negative than positive ions. However, positive ions are needed so the cell can fulfill its specific function.
Conversely, outside the cell we find more positive ions.
When our level of positive ions occur, our levels of prana (lit.: "always moving", energy, flow of life...) decrease."
And this would also explain the existence of air ionizers
Electrical appliances and devices, phone and wi-fi waves, etc. generate, and give us, positive ions.
Feng shui and other theories recommend not to have tv, etc. in the bedroom...
In case of need for negative ions and lack of rain, we also have beaches and coastlines (specially where waves break), natural spaces (specially moderately high mountains), any places with water....
Hope you may find this helpful.
