Salt lamp glowing pink

Himalayan salt lamps, carved from pink salt crystals, are cherished for their warm glow and alleged air-purifying properties.

About this subject

The pink salt lamp, commonly called a Himalayan salt lamp, is crafted from blocks of halite salt mined primarily from the Khewra Salt Mine in Pakistan. This salt, estimated to be over 250 million years old, contains minerals like potassium, magnesium, and iron, which give it the characteristic pink hue. The lamp is hollowed out and houses an incandescent or LED bulb; when heated, the salt emits a soft amber glow. Due to its hygroscopic nature, the salt attracts water molecules from the air, and when warmed, it is thought to release negative ions, potentially improving air quality, though scientific studies question the actual efficacy. Culturally, these lamps gained popularity in the West in the early 2000s, linked to wellness trends and minimalist decor. As of 2026, they remain a global trend, often used in relaxation spaces such as spas and bedrooms. The color variation, from pale pink to deep orange, depends on iron content and crystallization temperature. Larger, more translucent pieces are considered higher quality.

Frequently Asked Questions

Do Himalayan salt lamps actually purify the air?

There is no solid scientific evidence proving significant air purification. The negative ion release is too small to affect air quality in real-world settings, though many users report subjective wellness benefits.

Why does the salt lamp attract water?

Salt is hygroscopic, meaning it attracts water molecules from the air. In humid conditions, the surface may become damp or even form puddles. It is recommended to keep the lamp on for extended periods to evaporate moisture and prevent damage.

Where does the pink salt used in these lamps come from?

Most pink salt comes from the Khewra Salt Mine in Pakistan, one of the world's largest salt mines. The salt is extracted from deposits formed by the evaporation of ancient oceans, and its color comes from trace minerals like iron oxide.
