In our homes, offices, vehicles and city streets the atmosphere is overloaded with positively-charged ions that are depleted of negatively-charged ions, this is due to electrical interference and various pollutants. Decades of scientific research has shown beyond doubt that this imbalance in the air results in fatigue, headaches, irritability and exacerbation of respiratory ailments (Felix G Sulman, 1970).
Ordinarily, ions immobilise airborne germs, dust and mould spores. However there is a significant difference made by the smallest negative ions. These are tiny enough to be breathed into the lungs and circulate through the bloodstream, all while boosting the immune system - as research at La Trobe University in Melbourne has demonstrated.
That 'feel-good' sensation we experience at the seaside or in the mountains is hard to replicate in a modern urban environment.
Not all ions are the same size. There are small, medium and large ions.
Small (ingestible) ions are highly mobile and are biologically active.
Large ions are sluggish and slow-moving and merely clean the air of heavy pollutants.
