How Air Ions Affect Us

The effect of negative ion depletion (or an excess of positive ions) varies from person to person. The least fortunate can suffer migraine, asthma and even severe depression.

Most authorities on the subject agree that ions act on our capacity to absorb and utilize oxygen. Negative ions in the bloodstream accelerate the delivery of oxygen to our cells and tissues, whereas positive ions slow down this delivery of oxygen, producing symptoms markedly like those in anoxia (or oxygen starvation).

The body chemical serotonin, which scientists have identified to be linked with stress and changes in mood, is also influenced by air ion levels. Too many positive ions alter the levels, causing stress and discomfort whereas increasing the negative ion concentration helps bring relief.

Researchers believe that negative ions may stimulate the reticulo-endothelial system, a group of defence cells in our bodies which marshal our resistance to disease. Organizations that have installed negative air ionization equipment have found that their employees are less likely to get colds, report absent less frequently and are generally more cheerful and alert.

Scientists have also recommended the use of negative air ionizers in the closed and artificial atmospheres of submarines and spacecraft.

Our modern vehicles have their problems too! Basically they are a plastic-lined metal shell, with air supplied through ducting. All these factors dramatically increase levels of positive ions. Opening a window can cause further problems by letting in polluted, ion deficient city air.

Many drivers, (long-distance drivers in particular) find that using an ionizer in their vehicle improves their alertness and concentration along with the usual benefits of removing pollen and smoke. Passengers that suffer travel sickness, often report a significant improvement too!
