The purification effect of crystal salt lamp on air is realized by releasing vitamin anion in air: heated salt lamp absorbs water molecules in surrounding air to the surface. When salt and water molecules are mixed, sodium, as positive ion and chlorine, will return to the neutral state as negative ions, and ionized water is sent back to the environment. This unique ion generation process can only be achieved by crystal salt lamp, because the electric neutral atomic structure of crystal salt determines its ability to convert ions under thermal conditions. This unique crystal salt, known as rock salt, is a salt receiving type, which was formed in the end of Permian, 40 million years earlier than dinosaurs. The severe crustal movement of 280million years ago turned the ancient ocean into the Himalayas, which is now famous all over the world. The salt content in the sea water is deeply buried in the ground about 600 meters. After several billion years of compression and high temperature, the minerals at the bottom of the earth are combined with sea salt, thus forming rock salt deposits. It is said that the rock salt therefore contains 84 minerals needed by human body, and more abundant ionic mineralized substances. Crystal salt lights also relieve stress because of the natural orange red light that it emits. It is reported that crystal salt lamp can produce a prebiotic spectrum - Schumann light wave through translucent crystal structure, which is recognized as having a great effect in color therapy. In Germany, psychotherapists use light waves to conduct mental counseling. Gift for your Loved ones
