How Do Himalayan Salt Lamp Works?
Those who believe that Himalayan salt lamps provide several different health benefits point to two possible mechanisms: hygroscopy (dehydration) and air ionization.
The first potential mechanism is that rock salt has a strong affinity for moisture in the air. What that means is that the salt lamp attracts water vapor in the living environment, and the toxins, allergens, dust, and a plethora of other pollutants embedded in the air.
This process is also known as hygroscopy.
In other words, Himalayan salt lamps may help pull in harmful particles and pollutants from the surrounding environment, possibly acting as a natural air cleaner and purifier for your living space.
The magic of the salt lamp does not end there. Once the particle-rich moisture reaches the surface of the lamp, the heat causes it to evaporate, leaving toxins, dust, and allergens on the rock.
The clean water vapor goes back into the air, and the cleaning cycle starts again. As you can see, your salt lamp can work tirelessly 24/7 getting rid of bad particles from your room, so you can breathe easier, all while enjoying the fabulous glow given off by the rock.
Air ionization is another mechanism that Himalayan pink salt lamps are also thought to offer, with its potential health and therapeutic benefits.
More specifically, the salt lamps are believed by some to act as a natural air ionizer, which suggests that they release negative ions into the surrounding air.
