A Himalayan salt lamp is a decorative light source made from large chunks of pink salt mined from the Himalayan Mountains. These lamps are often hollowed out to accommodate a light bulb, which warms the salt and emits a soft, warm glow. They are popular for their unique appearance and are believed to enhance the ambiance of a room. Many people claim that Himalayan salt lamps can improve air quality by releasing negative ions when heated. However, scientific evidence supporting these health benefits is limited. Despite this, they remain a popular choice for home decor and relaxation.
