Himalayan Pink Crystal Salt contains the full spectrum of 84 minerals and trace elements just like Mother Earth intended. It is an unrefined , unprocessed "raw" salt that is hand mined from abundant salt caves that were formed 250 million years ago as ocean salt settled in certain geologic pockets around the earth. Salt lamps are blocks of pure Himalayan salt, so they come from the same region of the world. Also known as the ‘Vitamins of the Air’, they are made from the salt that came from ancient oceans, and serve as a perfect air ionizer. The lamp has a small bulb inside and is shaped in a sophisticated way to create a beautiful decorative object of an exceptional health value. Salt lamps emit negative ions. The bulb inside of the lamp heats the crystal and supports the ionizing effect. Salt itself is hygroscopic and attracts the water from the surroundings. You can often see that the lamp is damp or even wet, especially in more humid environments. Due to the gentle heat of the lamp, the water quickly evaporates and during the evaporation process the beneficial negative ions get created. They go on to bind with excessive positive ions (bacteria, molds and allergens all carry a positive charge) and neutralize the electronic smog in your home. Moreover, the lamp is a very pure source of light and its multi-colored glow has a soothing effect and relaxes you. Scientifically speaking, the Himalayan salt lamp achieves the following things: It ionizes the room. It balances artificial frequencies and unnatural electromagnetic wavelengths that originate from electronic appliances. It produces the light waves of the rainbow spectrum which protect your body.
