We should note that an atmosphere of open natural spaces (rural areas, meadows, pastures with little tree coverage, etc.) with a total absence of pollution may have between 1,500 and 4,000 ions per cubic centimeter, with a slight predominance (12 to 20 percent greater) of positive ions.

In typical forest areas in our latitudes the volume may be similar, but the relationship is reversed in favor of negative ions. In large rainforests the total ionic content in the atmosphere can be considerably higher, but the predominance of negative ions over positive remains the same.

For hundreds of thousands of years, human evolution took place primarily in these environments with similar levels of air ionization. Negative ions in particular were always abundant and readily available. Unfortunately, however, urban and indoor environments do not even come close to the ionization levels typical of more natural surroundings. We need to ask ourselves what the consequences may be for our health when we find ourselves living in places so poor in atmospheric ions, especially negative ions.
