These studies, however, used high concentrations of negative ions generated by industrial scale ion generators. Seeing as we have uncovered no evidence to support the claim a salt lamp produces any ions, the notion that a $29.99 block of rock with a light bulb could rival the power of a specifically designed laboratory equipment seems dubious. Much of the pseudoscience written about the positive effects of negative ions similarly disregards scale in their analyses, equating negative ionization at any level as the same phenomenon.
Scientists have studied the psychological and biological effects of positive and negative ions in the air for over 80 years. However, there seems to be no consensus as to whether these ions can actually influence a person’s physical and mental health. Currently, there is no consistent data to support the effects of air ions (either positive or negative) on sleep, relaxation, anxiety or mood (Perez, et. al, 2013).
 There are two main arguments one could make to suggest negative ions increase oxygen flow to the brain or provide you with more energy. The first one is that negative ions increase respiratory function and, as a consequence, would allow your body to deliver more oxygen overall. This claim, though oft repeated, has very little evidence to support it. A 2013 systematic review of papers investigating a relationship between exposure to ions and respiratory health stated:
Manufacturers claim that salt lamps can provide a variety of health benefits by releasing negatively-charged ions into the air. These negatively charged particles are said to do wonders for a person’s health by increasing blood flow, improving a person’s mood, increasing energy levels and providing relief from the symptoms of seasonal affective disorder (SAD).

This lamp is beautiful and unique and remains classic with it's style making it a beautiful addition to the home. With over 6,688 customer reviews on Amazon, this is our top pick!

Where do you purchase one that can be left on for long periods of time? I want to be sure if my fiance leaves the thing on overnight, we won’t burn the entire house down! My friend told me about the base of your salt lamp really matters. Wood doesn’t do so good, but having a steel base helps to absorb moisture and its safe to use for long periods of time. There’s so many brands out there manufacturing these, so be sure to look out for a steel base!
Salt is hygroscopic, which means it attracts water molecules to itself. Being the big hunk of salt that it is, a Himalayan salt lamp is believed to work by attracting the water molecules. This water vapor can also carry indoor air pollutants like mold, bacteria and allergens. Once the water vapor comes in contact with the salt lamp, the pollutants are believed to remain trapped in the salt. Since the lamp is heated, the salt dries out and is able to continue the cycle of attracting water vapor and pollutants, releasing the water vapor back into the air but holding on to the health-hazardous pollutants.
I used this lamp as instructed, leaving on a few hours per day. Today I came home after the lamp had been completely off and it had turned on on its own (despite switch still being turned to off) and the lamp was leaking liquid onto the table. The dimmer switch was very hot to the touch. The lamp could not be turned off without unplugging it. I only had this lamp a couple of weeks.
