A salt lamp is a decorative light source made from large chunks of Himalayan salt. These lamps are often carved into various shapes, such as blocks or spheres, and are typically hollowed out to hold a light bulb inside. When lit, the lamp emits a warm, amber glow, creating a cozy atmosphere in any room. Many people believe that salt lamps can improve air quality by releasing negative ions, which may help reduce allergens and pollutants. However, scientific evidence supporting these claims is limited. Despite this, salt lamps remain popular for their aesthetic appeal and potential health benefits.
