If you struggle with asthma or allergies, you may also benefit from an air purification system or machine, according to the American Academy of Allergy, Asthma & Immunology Indoor Allergen Committee. Air purifiers with high-efficiency particulate air (HEPA) filters can reduce the amount of particulate in the air and improve asthma symptoms. You can also install a high-efficiency filter on your forced air system to help remove particulates.
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.
Himalayan Glow 11" Salt Lamp is made of natural salt crystal from the Himalayan mountains. Each lamp is individually handcrafted and unique sits on a beautiful neem wood base. Comes with 25-Watt light bulb, the unique patented dimmer switch (fire resistant) 6' electric cord. Every component made according to UL standards including salt rock by itself. Complete lamp ETL certified.
 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:
World renowned Dr. Albert P Krueger, microbiologist and experimental pathologist, “worked with bacteria of the kind that float in the air and spread diseases “ mostly colds, influenza, and other respiratory ills “ and found that an astonishingly small quantity of neg-ions could kill them and quickly take them out of the air so they were less likely to infect people.” The Ion Effect, by Fred Soyka, p. 57, 1991.
Thanks to sites like this one,I bought 3 salt lamps. One that’s about a foot,and a half tall,with 2 smaller ones for: the master bedroom, living room,and home office. It’s been over 3 months now,and I feel they are keeping the air fresher/cleaner than my air purifier ever did. As for affecting our mood.I would say to some extent, yes due to the salt lamo’s warm glow. I always prefer,and use a dimmer for low light anyways. Trying to be “greener” by reducing emissions as much as possible. Drive a plugin car. At some point,I would love to install a battery wall, powered by solar.

Very simply, an ion is an atom or molecule that has gained or lost an electron. Both positive and negative ions exist in the air: positive air ions are generally molecules of carbon dioxide that have lost an electron, whereas a negative air ion is generally a molecule of oxygen that has gained an electron. Negative ions in the air attract particles of pollution and give them a negative charge, making them seek an electrical “ground,” and causing them to fall harmlessly to the floor. It stands to reason that we want to be surrounded by negative ions as a way of protecting our health.
These negative ions occur in nature via the effects of water, air, and sunlight. Have you ever gone for a hike through the mountains or near a waterfall only to feel rejuvenated? Negative ions are partly to thank for that wonderful feeling. Nature has the ability to heal, and proponents of Himalayan salt lamps argue these pink salt rocks can mimic, to an extent, the feeling you get from being outside.
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!
A Himalayan salt lamp will clean, deodorize and ionize the air, getting rid of unwanted pollutants and allergens. A salt lamp will help you say goodbye to dust, pollen, pollutants and smoke! Himalayan salt lamps are also known to increase your energy levels, remove negative ions, neutralize electromagnetic radiation, and provoke better sleep habits. The lamps improve mood and concentration, reduce static electricity and provide you with an environmental-friendly glow by a dim light bulb.
For smaller rooms, or simply for added variety, consider adding some Himalayan Salt Lamp Candle Holders to your collection. Alternatively, this Samgreho Wall Plug Himalayan Salt Lamp makes another great portable salt lamp. On the opposite end of the scale, if you are looking to make a big statement (or you just really love salt lamps), then this absolutely giant Indus Classic Salt Lamp is for you – but only if you have very deep pockets!
Negative ions bind to positive ions in the environment, neutralizing them before they have a chance to get into our bodies and wreak havoc. Studies have shown negative ions to help increase serotonin and oxygen levels in the brain, which can decrease drowsiness, alleviate stress, and boost energy. In fact, some studies suggest they’re as effective as antidepressants for people experiencing chronic depression or seasonal affective disorder.

 As discussed above, “boundless amounts” of negative ions would be a bit of a stretch, given the total and complete lack of any ions generated by our lamp. Ignoring that fact, however, brings us to the claim that positive ions make us feel bad and negative ions make us feel great. In terms of effects on mood, there is some research that suggests that negative ions can play a role in the treatment of seasonal affective disorder. A 1998 study in JAMA psychiatry found, for example, that:

Deep underground mines in Khewra, Pakistan, are the only source of true Himalayan pink salt. If you’re questioning whether you have a real Himalayan salt lamp, look for mention of Pakistan as the salt crystal’s country of origin. You can also ask the lamp’s maker about the salt’s origin, keeping in mind that it may list the country of origin as the location of the lamp’s assembly.
Also, your citation of an EPA website is useless. It just links to the EPA’s IAQ site, which isn’t helpful in trying to figure out what you actually were using from the site. I don’t think I’d use WebMD as a source either if you want to appear reputable to the more intelligent people who can spot bullshit. (Not say WebMD doesn’t have valuable info. Kinda like Wikipedia, a lot is useful and valid, but I would never use it as a source.)
Mauritane Salt Lamp is not only visually stunning but provides innumerable health benefits. It is natural negative ion generators. Simply put, salt attracts moisture. The interaction of humid air with the surface of the salt crystal releases negative ions. The negative ions bind to the position ions that are created by electronic devices known as “electronic smog” (computers, television screens, telephones, microwaves, etc.). The positively charged ions lose their damaging...
To get the full benefits of Himalayan Salt Lamps its generally recommended to leave the salt lamp turned on all the time, as the more you leave it on, the greater air ionizing and purifying effect it will have. The lamps are generally safe to leave on at all times, but if you plan on to leave your home for an extended period of time, for example if you go on vacation, then it’s best to unplug it until you return.
Ideally, you should place a lamp prominently in each room to feel the maximum benefit. Bedrooms and living areas are the best place to start as these are where you will spend the most time. Make sure that any lamp you choose is a genuine Himalayan Salt Lamp and not a cheap fake alternative as lamps made from rock salt will not produce the same health benefits.

Crystal salt comes from many places in the world. Many resources online will have you believe that only Himalayan salt is “real” and “authentic” but this is false information and most of the “sources” don’t actually own salt lamps or sell them. We have imported salt lamps from Poland (the birth place of salt lamps) and even Iran and have tested them with countless devices all proven to work the way salt lamps work.
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. 
Himalayan Salt Lamps are made from pieces of Himalayan salt crystals. They serve as beautiful interior decorations and act as natural sources of light. However, the many diverse functions of Himalayan salt extend far beyond aesthetics. Combined with a light source inside the lamps, the chunks of salt produce negative ions, which yield positive effects on indoor air. Placing a Himalayan salt lamp in every room of the home can reap several health and environmental benefits. Among other things, they can: 

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.
I think people should just try them for their selves and make up their own minds. I know a someone that has been a teacher for 30 plus years and she swears by them. She has used these salt lights in her class room for the past 5yrs and like she said it’s just her opinion but her class rooms have been a lot calmer since she’s been using them. SHE has even gone as dark as to have themy off for months just to see if they were truly working. Oh ya she is a elementary teacher.

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).

I have purchased six of these salt lamps. 2 for me and 4 for friends and relatives. They make a great gift. I have one on in my livingroom during the day and one in my bedroom at night. It may just be in my head but I actually do believe I sleep better. I love the beautiful glow and the dimmer switch is great. It can be very bright, very dim or many degrees of either. It makes a great conversation piece, nd gets lots of compliments.
