A Himalayan salt lamp is a decorative lighting fixture crafted from a solid block of Himalayan pink salt. These lamps are known for their soothing, warm glow and are believed by some to have potential health benefits due to the release of negative ions when the lamp is lit. Typically, they come in various sizes and shapes, with a small bulb or candle placed inside. Himalayan salt lamps are often used for ambiance, relaxation, and as natural air purifiers in homes and offices.
