An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a positive or negative electrical charge. All ions are charged, meaning like all charged objects they are "attracted to positive to negative or vice verse", "repelled by like charges", "travel in trajectories that are deflected by a magnetic field".
If atoms or molecules loses electrons due energy impact then it is a positive charged ion known as cat ion. Potent positive ion generators are decay of radio active minerals, ultra violet rays, electro-magnetic radiation from electricity, cell phones, computers, pollution from exhaust and smog, radiation from chemicals and toxic gases in the atmosphere. Positively charged ions induce negative effect on the body when you're exposed to them. Thereby harming and impairing the immune system of the body.
If atoms or molecules gain the electron then it is a negative charged ion known as anion. Potent negative ion sources are dense forest, lake area, beach area, near flowing water source like waterfall.Negative ion therapy is an alternate form of treatment using electrons to remove elements that have an adverse effect on the physical and emotional well-being of the individual. Negative enhances the flow of oxygen reserve in the body creating positive vibes. It gives a boosting thrust on the immune system. These negative ions heal our body as they uplift us mentally, physically and emotionally. With the right balance of negative ion within every cell of your body, it helps to accelerate healing, pain relief, mental focus, pH balance, tones skin and much more. It has high therapeutic effects. It restores and balances the body's energy, while facilitating and aiding the body's natural detoxification process. Negative potential energy balances the function of both sides of the cell membrane. This promotes a faster metabolism and assists to strengthen the body immune system and resistance to disease.
