How does a Himalayan salt lamp work?
Salt is hygroscopic, which is a scientific word meaning that salt attracts water molecules from the surrounding environment.
Water molecules float around in every room in your home. However, water molecules aren’t the only invisible substance hiding all around you. Alongside these water molecules are dust, pollen, mold, and other allergens. Even bacteria and viruses can hitch a ride on these water molecules.
A large block of salt, like a pink Himalayan salt rock crystal, works by attracting the water molecules in your room. In so doing, it also pulls in all the pollutants and contaminants attached to these molecules. The salt rock lamp helps to detoxify your room by capturing and holding these particles so they aren’t left floating around for you to breathe in. Then, as the bulb heats the lamp, the water vapour is released back into the air, but the rock salt lamp retains the contaminants.
Along with the hygroscopic benefits, Himalayan natural salt lamps are also said to release negative ions into the surrounding environment. For those curious, negative ions are simply oxygen atoms with an extra electron.
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.
