How Does Himalayan Salt Lamp work is a very common question comes in our mind when we study the benefits of using them. There are possibly two ways:
Pull in Particles: These Lamps supposedly attract allergens, toxins and air pollutants to their surface.
Possible Release Negative ions: Negative ions in the air (known as ionization) are supposed to have health benefits.
Himalayan salt lamps supposedly produce negatively charged ions while water molecules from the air attract to — and then evaporate from — the warmth of its surface. Those who believe in the health benefits of these lamps give negative ions much of the credit.
