Cilia are the finite hairs that line the windpipe and act like microscopic breathing filters. According to studies, positive ions decrease cilial activity while, conversely, negative ions have a more increasing and positive effect. Himalayan salt lamps are therefore believed to improve breathing by releasing negative ions that filter foreign particles and keep the lungs cleaner in general.

Despite numerous experimental and analytical differences across studies, the literature does not clearly support a beneficial role in exposure to negative air ions and respiratory function or asthmatic symptom alleviation. Further, collectively, the human experimental studies do not indicate a significant detrimental effect of exposure to positive air ions on respiratory measures. Exposure to negative or positive air ions does not appear to play an appreciable role in respiratory function.
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.
Taking a drive through the countryside with the windows down, spending time at the beach or camping in the mountains, or simply taking a shower first thing in the morning are all things that many people find invigorating. It’s not a coincidence that these are all activities which expose us to increased concentrations of negative ions such as those generated by Himalayan salt lamps. The fact is, positive ions sap our bodies of energy. Unfortunately, it’s all too common for us to try to diagnose the problem as something else entirely.
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.
There are a lot of products out there that claim to make your home a healthier place. Light therapy alarm clocks are thought to improve your overall mood and help you wake up more naturally; weighted blankets are designed to help you fall asleep faster and sleep more soundly. And Himalayan salt lamps are said to improve your home's overall air quality, which may be why they've grown in popularity over the past few years.
This wonderful accent light features a crystal salt block that comes from a mine at the foot of the Himalayas. Placed over a light source, the stone shines with a warm and inviting glow. It makes a perfect room accent in home theater settings, or add visual interest to side tables and display shelves. The stone sits in a hardwood base. The shape of stone may vary slightly. Salt Crystal is a Natural Air Purifier. The Himalayan Natural Crystal Salt Lamp also works as an air purifier. When lit...
[…] While some dispute the health claims of this type of salt, saying the mineral content is too small to make any sort of recognizable difference, many others use Himalayan salt as a healthy addition to their diet. Some people even enjoy the soft glow of a Himalayan salt lamp in their house as it is said to reduce positive ions in the home environment, improving health and well-being. […]
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.
Beauchamp was skeptical that a heated block of sodium chloride would produce ions (any amount of them, positive or negative ones, let alone “boundless amounts”) but not so skeptical that he didn’t want to hook up the most popular salt lamp available from Amazon.com to his lab’s quadrupole ion trap mass spectrometer. This instrument, in essence, sucks in air from directly around the solid and analyzes the mass and charge of particles captured by the instrument. Here’s Beauchamp description of what he did in his own words:
WBM’s Pink Salt Basket Night Lamp is unique. The bamboo Style Basket is made from Original bamboo filled with 100% pure Himalayan Rock Salt Crystals. WBM makes the best quality of the Himalayan Salt Lamps - salt crystals are hand mined in the Himalayan Mountains, specially handcrafted for uniqueness.

I purchased this item from Amazon and a year or so later the dimmer switch stopped working. When I took it apart to inspect I found the transistor (which is severely undersized for this design) had overheated and burned up itself and the circuit board. I searched the part numbers online and discovered this is the *exact same* board that has been recalled by other manufacturers (i.e., Micheals). I do not understand why Amazon has not recalled their version of it yet. It is a fire waiting to happen. I would not recommend anyone using this product.
