Salt lamps generate negative ions, which purify the air and create a number of health benefits, and they generally aren't known for creating a hazard in your living room or bedroom. Nevertheless, certain dangers are inherent with the use of salt lamps that you should be aware of before you buy one.
Electrical Hazards The dangers of using salt lamps also include electrical dangers and fire risk. Of late, 80,000 Himalayan salt lamps have been recalled by the Consumer Product Safety Commission due to overheating for a particular brand of salt lamps in the United States (which cut on costs and compromised the lamp quality).
To lump the original Himalayan Crystal Salt (which everyone is trying to claim is "theirs") into the same category as other "Himalayan Salt" (aka CRAP rock salt), is like comparing a Ferrari to a Volkswagen. There's no comparison. This article is so POORLY referenced, with a lot of inaccurate information.
