Salt lamps are decorative light sources made from large chunks of Himalayan salt. They are often carved into various shapes, such as blocks or bowls, and contain a light bulb inside. When lit, these lamps emit a warm, amber glow, creating a cozy atmosphere in homes and offices. 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 calming effects.
