People need a balance of positive and negative ions concentration to keep healthy. Balance, generally refers to the balance of hydrogen ions in the body of hydrogen ion concentration changes in body, can make the body acidic or alkaline. Rapid changes in hydrogen ion concentration, will affect the cells and tissues balance of cells and tissues of ions out of balance, will change its normal activity functions.
Positive ions (cations) generally has a negative effect to the body, whereas negative ions (anions) was found to have a positive effect to the human body. Cation is seen as the change of blood pressure, heart beat faster, slow recovery rate and causes of action affects the heart and nervous system. We found that the body's response to excess positive ions, and the sympathetic nervous system, the response to stimulation.
Instead of the negative ions were found to have a positive effect to the human body. Negative ions can stable heart, lung and blood vessel function. What's more, it also to the person's emotional memory, the function and behavior produce a positive result. The effect of negative ions and parasympathetic activity effect.
The balance of positive and negative ions, the function of keeping to the human body is necessary, any obvious the change of ion concentration, bad influence on health.
