Positive ions in the atmosphere have harmful effects on health while negative ions are beneficial. Our bodies make extensive use of irons such as Calcium (Ca++), Potassium (K+), Sodium (Na+) for Transmitting electric signals between the brain and the nerves. Ions interfere with the body's own internal communication system. The arteries and the red blood cells are slighty negatively charged. Since they repel each against each other, blood cells do not get attached to the artery walls or to each other ensuring smooth flow along the narrow channels.
However when we inhale the positive ions, they enter the lungs and then the blood stream, where they lessen the negative charge on the blood cells.Thus the adhesion on the arterial walls is increased and circulation efficiency decreases. In contrast, negative ions increase circulation efficiency.
