Himalayan salt lamps attract water molecules from the surrounding environment then absorb those molecules. As the lamp warms up, it attracts moisture which evaporates producing negative ions. Pollen, dust etc carry positive ions. The negative ions neutralize the positive. The trapped particles of dust etc get trapped in the salt purifying the air.
Himalayan salt lamps are well-known for their incredible power to remove dust, pollen, cigarette smoke, and other contaminants from the air.
How Himalayan salt lamps cleanse & purify the Air?
Himalayan pink salt lamps purify air through the power of hygroscopy, meaning that they attract water molecules from the surrounding environment then absorb those molecules – as well as any foreign particles they may be carrying – into the salt crystal.
As the lamp warms up from the heat produced by the light bulb inside, the salt lamp attract moisture from the air to the lamp surface, where, due to the warmth, the water evaporates quickly. The evaporation produces negative ions. Pollen, dust, dirt, pollutants, and allergens in the air all carry a positive charge, and that is how they can be suspended in the air. The negative ions neutralize these positive ions so they can no longer be airborne. That same water then evaporates back into the air and the trapped particles of dust, pollen, smoke, etc. remain locked in the salt.
Numerous studies show that negative ions boost mood, relieve seasonal affective disorder, and improve breathing problems such as asthma. Himalayan salt lamps provide an inexpensive solution with the same benefits.
Benefits of the Himalayan Pink Salt Lamp for a restful sleep
The side effect which results from over-exposure to positive ions in the air is that it deprives you of quality sleep. This happens because those positively-charged particles can reduce blood and oxygen supply to the brain resulting in irregular sleep patterns. Himalayan pink salt lamps are natural negative ion generators, thus they can help to reverse this problem. Keep one or two around your bedroom to improve the air quality so you can get a better night’s sleep.
