Himalayan salt lamps can be used as an aid in color therapy (chromotherapy), an alternative method of diagnosing and treating a large number of illnesses. They produce a soft light in hues of ambient orange, yellow and red that helps with stress, attention deficit disorder, and general relaxation, among others. The serene light is thought to balance physical, spiritual and emotional energies. 
At any rate, we plugged the unit into an electrical outlet, dimmed the light to a very pleasing dim orange color and placed the lamp on a table. The lamp has been turned on 24/7 for a couple of weeks now. The dimmer is cold to the touch and we have experienced no issues whatsoever with the product. We are very pleased with the lamp, its appearance, and the nice pinking-orange dimmable warm glow it casts.
The structure aspect is important, says Beauchamp. One way to get crystals to generate ions is to alter the shape of its crystal structure via temperature, something that can happen if a crystal structure is asymmetric. He points to a crystal called lithium tantalate, which changes its crystal structure when heated up in such a way as to create areas of high and low electrical potential when heated or cooled. This property allows it to generate an electric field that could, in theory, ionize the air around it. Sodium chloride’s chemical structure is a symmetrical cube that does not have the capability to generate high electric fields in the vicinity of a crystal.
The unique large salt lamp is made from salt crystals gathered at the foothills of the Himalayas; thus ensuring their deep and mineral-rich scarlet glow. Heating the salt with the included bulb releases negative ions into the air, creating an effect similar to an ionizer. The outside surface of the lamp stays cool to the touch, as the heat of the light is dissipated within the salt. Due to the natural variation in rock salt, weight, size, color, and shape may vary. The shape of stone may vary...
That doesn’t mean the lamps are totally harmless. The retailer Michaels had to recall several due to shock and fire hazards in January 2017, and Kogan says it’s possible the lamp could pose problems for people who are already struggling with lung issues. “Some people with interstitial lung disease, such as pulmonary fibrosis for example, or cystic fibrosis, they may be sensitive to the salt particles themselves,” Kogan acknowledged.
BHandari foods offers you Himalayan salt which is Himalayan crystal salt is far superior to traditional iodized salt. Himalayan salt is millions of years old and pure, untouched by many of the toxins and pollutants that pervade other forms of ocean salt.The health benefits of using natural Himalayan Crystal Salt may include,Controlling the water levels within the body, regulating them for proper functioning,Promoting stable pH balance in the cells, including the brain.Encouraging excellent blood sugar health.
When it comes to buying Himalayan pink salt lamps, coverage is determined by the size of the crystal. Smaller lamps (like this 5-8 lbs lamp) are good for the average bedroom, while larger lamps (like this 11-15 lbs lamp) are better for spaces like the living room or den. On average, calculate that 1 lb of Himalayan salt crystal will cleanse the air in approximately a 4′ x 4′ area.
Rose McClintick, a QXCI Practitioner and Biofeedback Analyst, who has been working in the holistic health field for seven years, tested our salt lamps and offered an enthusiastic endorsement in regard to their generation of negative ions: “Regarding the salt lamps, I can tell you that my test shows that it has improved the negative ions. (They) will be recommended to have in the bedrooms. You get both working for you, improved neg. ions and a better night’s sleep.” Zykoff Bodywork
Even though they don’t make a huge difference in negative ions and they aren’t going to be as effective as an air purifier, they make a great addition to a space and definitely have a positive impact in some way. The aesthetic alone makes the lamp worth keeping around, and if it has an effect on the air and helps to calm our minds even in the slightest, then it’s even more worth it!
Like several comments above, I also smelled something burning one night in my office and couldn’t figure out what was the culprit for awhile. When I located the source of the problem and tried to turn off the salt lamp, I almost burned my hand by touching the dimmer/switch. As you can see from the photo, part of it was melted. Glad I was there that night. Or my office would have been on fire!
