Many of us live and work in surroundings dominated by computers, televisions, microwave ovens, air conditioners and heaters to name but a few. These conveniences emit excessive amounts of positive ions into the air. This can result in mental and physical exhaustion and affect our health. The most dangerous levels of positive ions occur in polluted cities. Exhaust fumes from vehicles, cigarette smoke, dust and electromagnetic pollution combine to create a potent mixture of positive ions and ozone that gradually affects our health.
Negative ions are odourless, tasteless and invisible molecules that we inhale in abundance in certain environments such as mountains, waterfalls and beaches. Once they are in our bloodstream, negative ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress and boost our energy.
