It is possible that the negative ions released by Himalayan salt lamps may protect against airborne germs. In addition to removing these contaminants from the air, the salt also allows the body to filter air more effectively in an attempt to block any foreign particles from making it into the lungs. This can prevent the advancement of coughing, sneezing, sore throats, and other minor symptoms of the common cold. 

Received 2 as a Christmas gift from my husband hoping to help with my sinuses. Can't speak for that as I've only had them on for 2 days. They are nice size. Love them and plan to purchase 2 more for my house. Love that they have a dimmer switch but wish it were closer to the lamp as you have to see the cord or reach behind other things to turn it on/off. I just leave mine on.
A few isolated studies have shown modest and equivocal effects from negative ionization. For instance, in 1981, researchers at the University of Surrey in England looked at the incidence of stuffiness, nausea, dizziness and headaches in people in an office environment. They found office air had fewer negative ions than is typical outside. So the team conducted a double-blind study and found that the reintroduction of ions reduced the incidence of these symptoms over a 12-week period. The findings were published in the Journal of Environmental Psychology. A 1993 study published in the Journal of Human Ergonomics found that negative ions could slightly affect people's circadian rhythms, although they had no impact on anxiety or exercise levels.
 This claim has existed sporadically in the scientific literature for decades, but ultimately is not supported by current science. A 2013 review of psychological effects attributed to air ions, which looked at 33 studies from 1957 to 2012 evaluating “the effects of air ionization on depression, anxiety, mood states, and subjective feelings of mental well-being”, concluded:
“The lady doth protest too much…” This article suggests to me that the writer or those who have paid to writer has a hidden agenda. And I’ll cite that science has made our world into a shit hole where we are now browbeaten into accepting and trusting conventional gangster snake oil medicine, pesticides, herbicides, fluoride, mercury laced vaccines, etc., and so on, all of which is touted to be good for us but which is poison to us while we are ridiculed and discouraged by science “experts” from using natural solutions. Science and scientists have betrayed us. And why? Because they are funded by those who want to continue to poison us. If the writer of this article is in earnest, then the writer has been thoroughly, successfully indoctrinated into serving on the wrong side of history.
We’ve had a salt lamp in the bedroom for many years, however we don’t know if it makes a significant difference or not. Shortly after purchasing it, the little “light” that was inside stopped working. I have never purchased anything that has this kind of light to last very long as the lights are very cheap and poor quality. So we always wonder if the salt lamp has any beneficial effects at all without the heat and light coming from the bulb inside.
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.
Hi Alex, Himalayan salt lamp is a type of rock salt lamp – they are made from salt crystals from the Himalayan mountain regions and come in variety of shades such as white or orange/pink. There are other rock salt lamps that come from a number of other locations throughout the world (although some claim that the finest quality comes from the Himalaya).

Said to improve sleep by increasing levels of serotonin in the brain and adding calming energy to the room, Himalayan salt lamps are a must-have for any bedroom. Take this one for example: made in Nepal, it features a circular wood base topped off by a natural 8" rock-shaped design that has been handcrafted from salt crystals with a pink hue. When you turn the light on inside, it casts a warm, amber-hued glow over your ensemble. Arrives in a set of two.
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.
