There have been many claims made over the years about himalayan pink salt lamps (negative ion generator). Properties of these lamps are supposed to range from purifying the air to preventing cancer.
These lamps supposedly boost health by releasing negatively-charged particles into the air.
But are they truly beneficial, or is this all a bunch of hyped up talk in order to boost sales of the pinkish-orange illuminated rock.
What is said to happen
Natural living proponents and other fans of Himalayan pinksalt lamps (HPS lamps) claim that the negative salt ions released by heating can boost blood flow, improve sleep, increase levels of serotonin in the brain, and calm allergy or asthma symptoms.
These negative ions are said to neutralize electromagnetic radiation from household electronics, and even prevent the build-up of static electricity.
Is it true though?
How salt lamps work
Salt is hygroscopic, so the lamps attract water molecules from the air; this means the lamps trap dirt, pollen, and smoke particles which are carried in water vapor.
Once these airborne contaminants have been locked in the salt, clean water is re-released and thus it has a purifying effect on the air. Supposedly. of course.
The heat from the bulb inside that warms up the lamp releases negative ions. And there are the health-boosting effects of salt itself too.
