Himalayan crystal salt lamps aren’t just an attractive addition to your living space, they could be good for your health too.
Chiselled from solid blocks of crystal salt with a hollowed out centre for an electric bulb, these pinkish-orange lamps work by removing contaminants from the air and converting harmful positive ions to beneficial negative ions – all while producing a soothing light.
There is always water vapour present in the air in any room, containing dust, pollen and dirt particulates, which the salt lamp is able to remove by the power of hygroscopy. As the lamp warms up due to the heat produced by the bulb, water molecules are mopped up from the surrounding atmosphere. The contaminants are absorbed by the salt and the purified water evaporates back into the air. So you can see how this could help people suffering from allergies or asthma.
The salt lamps also change the charge of the molecules released. Positive ions released by electronic devices, for example, can cause microscopic hairs (filia) in the trachea to preform sluggishly, while negative ions are beneficial for energy, mood and general wellness.
