Salt Crystal Lamps

I just bought a Himalayan Salt Crystal Lamp which, when heated, becomes a natural negative ion generator. Negative ions clean the air of dust, pollen, dust mites, animal dander and mold spores.

These lights work by supposedly lower the electric fields radiated by appliances such as computers and televisions. Increased electricity in one's living space results in lack of concentration and insomnia so I think that these lamps might help me sleep better. They say that in Europe and Russia ionization of the air in hospitals and work places has become mandatory and helps people with respiratory problems, chronic fatigue, allergies, sleep disorders, migraine headaches, asthma and depression.

Even if none of this is true (and I'm not saying it is untrue but it is difficult to measure), these lamps are very beautiful and look very neat in a den or living room:

Here is the website for these lamps.
