The air all around you is made up of molecules, all of which have an electrical charge to them. Negative ions are good for you. They encourage optimal oxygen supply to the brain, boost immune responses and help lift low moods. Studies show they may even help lessen depression. Tested and researched to produce negative ions, salt lamps are well known in Europe and most people will feel the difference in the air quality right away. The emission of ions is primarily caused by the alternating actions of the salt’s ability to first absorb water then evaporate it. The unique ion emission salt lamps possess is due to the transformational ability of the electrically-neutral mineral salt molecule. It has also been reported to help relieve hay fever and migraine symptoms and post-operative pain. Once you experience how good you feel with lots of negative ions around, you will want to have them around all the time.
