Negative Ions

Negative ions support oxygen uptake in the body. Pine forests generate and contain more negative ions than other forest types. Negative ions are electrically charged oxygen molecules. Water droplets passing through air generate negative ions. Negative ions form in environments where moisture, movement, and air circulation coincide. Greater responsiveness to air movement in pine needles is the reason pine forests have higher negative ion levels. Negative ions occur naturally in thunderstorms, waterfalls, and the ocean. Naturally occurring phenomena that combine moisture, movement, and air circulation are significant sources of negative ion exposure. Pine forests are particularly rich sources of negative ions. The presence of negative ions can be detected by a characteristic fresh, clean scent even without visual or auditory cues. Moisture, movement, and air quality are key indicators of environments with high negative ion concentrations.
