    Salt lamps with Himalayan salt (it's pink because it's contaminated!) also contains toxic chemicals that can be released into the air and hurt you and your pets.
    Please do not let your pets lick the salt lamp! Pets are smaller than you and should not injest too much salt!

    I can't believe we live in a country that allows products on the market that don't do what they say they are supposed to do, and especially if they cause harm by releasing pollutants. This is why we need to get the money out of government and especially get the anti-science neanderthals out of office.

    I love that science can so easily explain things that people pulling stuff out of their ass or repeating what someone else pulled out of their ass cannot. It's rare that there is ever even a grain of truth to woo woo ideas, but it's good to know what is and isn't true if there is some truth there.

      The ozone layer is self-repairing from the UV-induced reaction of oxygen into ozone. Human intervention would not be needed.

    The NIOSH recommended exposure limit for ozone is 0.1 ppm, so not the level that the ionizer reaches.

    I appreciated that you distinguished between clarifying low anion density effects, high density anion density, the issue with the anion studies itself, the salt lamp, potential tourmaline, and natural sources, maybe effect on pollutants etc. Teasing apart what part could be plausible vs probably not vs kind of speculation Well done. More helpful than bashing with little explanation

    I have never assumed they work by ionisation but by reducing the blue spectrum light that suppresses melatonin. Either that or they are simply less bright. In the search for what works, its often better to not throw the baby out with the bath water but instead, understand perhaps why something works and how powerful that effect is. I remember when I was a child yoga, massage and meditation were all considered the placebo effect. 30 years later the research has finally caught up.

    I have an Ionizer in my car and I can say it confirms what they said at the end - The Ions cling to any chemicals or big particles and stick to the surface. I found that when I have it on, my car feels clean and the air inside has no particles flying around, so at the very least I am not breathing them in.

    So, is it always just the exercise, the walk to a specific location? - Asking because I read a while ago that higher places above plains have a relaxing effect on people; reasoning was that our ancestors prefered them as they offered a way to see far and unobstructed, making it easier to see enemies, so they felt safer. - Another time it was natural bodies of water that had an inherant relaxing effect supposedly. - Any insights?

  • solokat1980
    solokat1980 27 days ago

    Very misleading video! Truth is that a salt lamp will oxidize the air, not ionize, which still can be beneficial. Also... when a small amount of ozone is created by high voltage negative ionization of the air, the ozone can also be beneficial, as it oxidizes the air. Ozone is not a pollutant! Ozone neutralizes pollutants. Too much ozone would be harmful though, just as too strong of a hydrogen peroxide solution would be harmful.

    Yikes! This video debunked quite a few conventional wisdoms. Salt lamps failed because they literally don't produce ANY negative ions at all, and air purifiers failed because they fill the air with potentially harmful ozone. The air purifier revelation is particularly alarming, since such products may be harming peoples' health, not helping it. Regulators seriously need to look into that.

    The electronic lab in which I am working uses air ioniser fans to make the air more conductive to prevent buildup of electricity charges which would cause ESD damage in electronics.
    Sitting next to these fans, I noticed that I get headaches and tired. Suspected it could be the ozone, but now I know it's definitely not the ions
