An awesome way to increase exposure to negative ions is to spend more time in nature, especially around water. Himalayan salt lamps are said to emit negative ions in small amounts and cancel out positive ones. By neutralizing electromagnetic radiation, they may help reduce the negative health effects of harmful electrosmog. Balancing positive and negative ions also may help reduce airborne infections. (4)
Beauchamp was skeptical that a heated block of sodium chloride would produce ions (any amount of them, positive or negative ones, let alone “boundless amounts”) but not so skeptical that he didn’t want to hook up the most popular salt lamp available from Amazon.com to his lab’s quadrupole ion trap mass spectrometer. This instrument, in essence, sucks in air from directly around the solid and analyzes the mass and charge of particles captured by the instrument. Here’s Beauchamp description of what he did in his own words:
First of all, salts are compounds which are made from combinations of elements that form ionic bonds. Ionic bonds are chemical bonds where the valence electron(s) which participate in bonding are not shared equally by the two atoms. Ionic compounds form in nature with a nearly perfect balance of charge so that there are just as many positive ions as negative ions in the compound. Because of this if a big block of salt were to release lots of negative ions into the air it would develop a net positive charge which would not allow more negative ions to be released. One way that negative ions could be released is if the block of salt released both negative and positive ions into the air in equal proportions. This, however, would have just as much of a negative effect, from the positive, “free radical” ions, as a positive effect from the negative ions.
