Salt lamps are decorative light sources 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, they emit a warm, amber glow that can create a calming atmosphere in any room. Many people believe that salt lamps have health benefits, such as improving air quality and reducing allergens. The idea is that they release negative ions into the air, which can help counteract the positive ions produced by electronic devices. However, scientific evidence supporting these claims is limited.
