Interesting comments regarding salt lamps and your interview with a lamp seller with no clue (as are 99% of the others methinks). The correct answer about salt lamps is as follows:\n\nThe myths floating around are originally based on a book titled "Water and Salt: The Essence of Life". This book states that salt lamps will fill a room with negative ions being ejected from the salt in copious amounts. Not true.\n\nSalt lamps attract water molecules from the air by hygroscopy. The evaporation of water, and reaction with sodium chloride, create negative ions, however they are short-lived and don't make it far beyond the lamp.\n\nImproved indoor air quality is achieved because attached to airborne water molecules are all the airborne irritants like viruses, bacteria, mold, and fungi; with a long list of asthma and allergy triggers as well. Moisture is REQUIRED for these things to remain in the air and viable; otherwise they fall to the floor...leaving surrounding air healthier.\n\nWhat extends the effect a salt lamp has in a given room is directly related to humidity, along with a lamp's salt surface area and the warmth of the lamp. Warmth creates a rising convection of air from the lamp and adds circulation to some degree. Existing conditions and individual sensitivities dictate the overall benefits realized. For some a little, for many a great deal. More about salt lamps here.
\n\nI've worked with salt lamps exclusively for over 6 years. I've researched, handled, and lived around Himalayan salt lamps enough to understand that they are NOT pseudoscience, quackery, new-age nonsense. I've only touched on salt lamps here, there is still the use of edible Himalayan crystal salt vs ANY other salt. Which way to that debate?\n\nThanks for reading.\nDarrin Wright\nIonicsalts.com\n\n
