Salt lamps add negatively charged ions into the air which improves the quality. Positively charged air, on the other hand, produced the opposite responses and tends to be associated with:
Headaches
Anxiety
Dizziness
Nausea
Depression
Breathing difficulties
Fatigue
Even though they are not a "medical device", Salt Crystal Lamps, by emitting negative ions, significantly reduce a myriad of indoor air pollutants and may provide relief from sinus, migraine headaches, allergies and hay fever, reduce the severity of asthma attacks, enhance the immune system, increase alertness, increase work productivity and concentration, increase lung capacity and reduce susceptibility to colds and flu.
