Himalayan Salt Lamps are made from Himalayan salt crystals and can help to purify indoor air, reduce allergens and improve mood.
They are natural negative ion generators. At any given time, there are both positive and negative ions in the air. Negative ions occur more often in nature and they are often created by things like lightning storms, sunlight, waterfalls, and ocean waves. This is one of the reasons people often report feeling renewed or refreshed after a storm or at the beach.
Positive ions are often created by electronic devices like computers, TVs, microwaves, and even vacuum cleaners and can often exacerbate problems like allergies, stress and sleep trouble. Negative ions can neutralize positive ions and help cleanse the air.
The unique combination of salt and a light source in salt lamps are what cause the negative ions. Salt is hygroscopic, meaning that it attracts water to its surface and this water evaporates quickly due to the small amount of heat from the light source which is why salt lamps tend to sweat and appear wet. The negative ions are generated during the evaporation process.
Since things like airborne mold, bacteria, and allergens often carry a positive charge, they can be neutralized by negative ions.
WebMD explains some of the benefits of negative ions in the air: Generally speaking, negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy,” says Pierce J. Howard, PhD, author of The Owners Manual for the Brain: Everyday Applications from Mind Brain Research and director of research at the Center for Applied Cognitive Sciences in Charlotte, N.C.“They also may protect against germs in the air, resulting in decreased irritation due to inhaling various particles that make you sneeze, cough, or have a throat irritation.” And for a whopping one in three of us who are sensitive to their effects, negative ions can make us feel like we are walking on air. You are one of them if you feel instantly refreshed the moment you open a window and breathe in fresh, humid air.
