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 
  
  All lamps come:
• With a bulb (appropriate to size of lamp)
• With a unique stainless steel GAMA Quick-Change Light Bulb assembly
• Mounted on a Wood Stand
