From Have you tried a Salt Lamp? : Dr. Leonard Coldwell.com
The air is filled with negative and positive ions. To maintain a healthy atmosphere, these negative and positive ions must remain in balance. However, technology today, like electronic devices, motor vehicles and our heating & cooling systems produce so many positive ions that our air is thrown off balance; resulting in stress, sleep disorders, migraine headaches and allergies to name a few. For example, most of our televisions run on a frequency of about 100-160 Hz. However, our brainwaves only vibrate at around 8 Hz. The television vibrates at a rate of more than twenty times faster than our brainwaves! Is it any wonder why we have so many diagnosed with ADHD, nervousness, and insomnia? It also causes the body to produce free radicals that can cause cancer, among other things. Placing a salt lamp besides the television and other electronics will help increase the amount of negative ions (which are the good ones). I remember when I first put salt lamps throughout the house, my mom came to visit and asked if I had drugged the kids! She couldnāt believe that the lamps had made that much of a difference. Trust me, in a house full of eight kids, you notice when they calm down. Three of them had a diagnosis of ADHD and it really did make a difference in their behaviors and their ability to concentrate.
Will soon visit Khewra salt mine with my children and plan to buy salt lamps from there for ADHD and Allergy IA
