Negative Ions are generated upon distortion caused by heating the chakra gemstones in the layers of your Zenergy Healing Mat. This increases the amount of oxygen flowing to the brain and body which boosts the immune system, mental acuteness and reduces the toxins in the body. Naturally creating fast-moving ion particles that cleanse and purify the air as well. This facilitates reduction in stress and fatigue, improved sleep, and improves body mineral uptake. Negative Ions can be found in natural settings such as waterfalls, ocean surf, evaporating water, and minerals like tourmaline.
