Remember the beautiful air close to waterfalls? Or on a dewy, fresh-air morning? Or after a thunderstorm? Or in the rain forest? Or the mountain top?
These are all places rich in negative oxygen ions and our body just loves breathing them. It feels nourishing and energising. We move on, feeling regenerated and fresh. Cleaned of dust and allergens, such air is nourishment to our bodies.
Indoor air easily becomes dusty and gets depleted of the essential negative oxygen ions by electrostatic surfaces, heating and air conditioning, see research in Information pages.
