Do negative air ions improve mood, anxiety, depression, alertness?
Part of this video was sponsored by LastPass, click here to find out more: bit.ly/2RZZTZk

Special thanks to Prof. Jack Beauchamp and Dr. Nathan Dalleska from Caltech for all their help running these experiments and discussing the research. For more, check out the links below:

If you want to dig into the research on negative ions yourself, I suggest starting with the review studies:

8:51 "So, your conclusion is that it's not producing any negative ions?" "We certainly aren't able to detect any ions." I love his response. It's such a humble, carefully worded, and scientific response. He doesn't say definitively that the salt lamp is not producing ions, just that they simply are not detecting any ions from the salt lamp. It is a subtle but important distinction, and a great example of how easy it is to develop hubris from literally anything if you're not paying attention to yourself. The scientific community ⁠- no, the _world_ needs more of this.

These salt lamps are great, I've had one for many years. Even when I bought it I didn't truly believe it was going to cleanse the particles in the air or something, I wanted it because it has very similar light and mood to a candle. It's a soft calming light and that's why peoople buy them.

@I Z "it's literally in the definition" So in your mind the "scientific community" are people who perfectly apply the scientific method? So no one? "What are the "appointed authorities" saying that you disagree with and on what basis are you disagreeing? Your intuition?"

I'm so glad you put a logical and scientific explanation to this craze that gets so misused by certain people.. no offense. The things are still awesome, I collect rocks so I appreciate minerals, crystals but I don't think they heal me in anyway other than the benefit I get mentally and physically by going out and gathering them in Nature, exercising as I collect and gather rocks and hike my dogs. That alone. That experience, the act of exploring, hunting, finding. Is so beneficial to my soul and mind. Then just being out in the woods here in Oregon and exploring the woods is the best type of therapeutic experience for me. It's like active meditation because even tho I am not sitting in one place - I am in a state of hyper awareness and I get in tune with my observation skills more and more each time I go exploring in the woods. There is just something magical about going on a walk in the wilderness by yourself and with your dog. Or, just by yourself if you don't have any dogs. The experience of hiking alone innately teaches you a lot, even if it's subconsciously. Nature is a amazing teacher, and you can learn how to be more connected to yourself, just by practicing going on solo hikes in the woods. (The one thing I am facinated about, is the effects scientist's have found Magnetic field waves are showing medicinal benefits and I'm curious to see where that field of science is going to go and evolve to...? 🧲🧠👍🏻)

Not wanting to waste electricity 24/7, I removed the power cord. The salt blocks work really well for absorbing humidity in my kitchen when we have rainy/ sultry weather. Just remember to place a dish under the lamp to hold the accumulated water if you leave it turned off.

Not having watched this video as yet, I have issues with these lamps as a chemist for a few reasons. One, the salt is held together by ionic bonds... you need temperatures much hotter than a lamp to ionize the salt crystals. Secondly, a chemical "salt" consists of both positive and negative ions... any temperatures high enough to break apart the saly into component ions will generate both types, which will recombine as very tiny salt crystals the moment the heat is removed and the positive and negative charges are drawn back together.

Love this! I have a whole Himilayan Mountain range of these lamps in my house, but have only ever purchased them for their aesthetic qualities, a.k.a their moody pink and orange glow. Everytime anyone comes over and comments on them, I feel I have to give them the disclaimer that I don't actually believe the new-age-woo associated with them, and that they're just for decorative purposes.

Like others have said, I had no idea salt lamps were meant to be a woo generator. I have also never had a salt lamp that didn't act as a dehumidifier and leak everywhere/rust to bits (underneath) so after the second one went bad I've never gotten another one. I know that ionisation is not woo. I am referring to the practice of attributing shaky science to something intended to increase one's wellbeing. Here's looking at you Body Mind Spirit expo!

Basically someone who is entirely unqualified to speak on the topic, but somehow has the authority to dictate public response. Absurdity at the highest levels. Yet the people just drink up the coolaid and never question actual the actual expertise of those reporting. Because....... they're experts right.

Given the makeup of a salt lamp, wouldn't the only negative ions it could release be chloride ions? Seems like that would probably not be the best thing to breathe.

@Xenophilius It's also the flipside of the more well-known Dunning-Kruger effect, where people who have a small level of knowledge in a topic greatly overestimate their expertise because they know a little bit about a subject but they don't know enough to grasp just how much they don't know. Truly, a little knowledge can be a dangerous thing, and Socrates famously said that true knowledge begins with knowing what you don't know. But true experts have such a deep understanding of the subject and all its nuances & complexities that they tend not to make oversimplified or black-or-white claims; they even tend to rate their subjective expertise lower than the overconfident people who have a low level of knowledge. It makes sense, they spend so much of their time learning about the bleeding edge of a subject and wrestling with the difficult to answer questions that are the current focus of research in a subject, as well as understanding the deeper intricacies that often underlie simple facts or the different ways of conceptualizing a single topic. I tend to look for that fuzziness of certainty as a hint that someone really might know what they're talking about, especially since on the other hand the quack & the snake-oil salesman will often make bold, sweeping statements involving claims of "absolute proof!" or perfect confidence in simple answers to difficult questions.

I have the lump of salt left, it's pretty, natural and looks good with indoor plants. The bulb fitting rusted years ago, so that's well gone. Not surprising with all that salt.

Salt lamps are great at looking pretty and providing mild illumination. Sure is a shame people insist on making all kinds of wild made-up claims about them in order to sell more of them. Would be nice if we could just appreciate salts and crystals etc simply for what they are.

Scientists rarely say "this doesn't do that". If you noticed, they never said that the salt lamp produced no negative ions. Instead, they said "we cannot detect any". Few scientists will deal in absolutes.

I thought the purpose of these lamps was to give off microscopic salt particles. Didn't ever hear they were for generating ions. Breathing salt particles from the air is supposed to be the beneficial effect. Salt water in a neti pot, salt gargles, saline eye rinses are all standard. Dry salt particles should also be useful.

@hzuiel Maybe not necessarily placebo. Placebo suggests using a control to help an ailment. Warm light being soothing is a different phenomena than a control, but it is distinctly a different thing that tones down mental arousal and relaxes people that does actually have some degree of scientific merit behind it.

I always chalked the atmosphere after a thunderstorm up to the ozone that is produced by the lightning. You can smell it. I don't know anything about this ion business. The lamps do look cool though, and I think they have value purely as a decoration item. I don't think I would buy one, but I don't mind the sight of them even if they are likely to be in the home of a crystal worshipper.

Apparently rainfall and waterfalls ionise the air, usually negative ions as far as I recall. People generally like the feeling of breathing the air after a rainstorm or near a waterfall. Also, burning Bees Wax is said to create negative ions instead of burning parafin based wax. Is it negative ions that make us feel better or is it that ionised air can attract dust etc? Still, it is interesting to know that over 100 years it is still being looked into

Did you do a double-blind comparison of the salt lamp versus a small chalkboard? I think the daily use of a small chalkboard at your desk for notes or a To Do List, could match the chalky deposits of the salt lamp.

the salt lamp makes the air smell amazing in the close vicinity of the salt rock, as long as the bulb is a heated bulb. i changed the bulb to a heatless LED bulb and the salt no longer makes the air smell any differently.

I always figured the ions part was bs but felt other than a glowing chunk of salt being cool to have, that a warm big chunk of salt kind of dehumidified the air. Idk might just be a mental/placebo effect type of thing.

There are always ions they’re generally ambient but alway react to relative charge. So if your not detecting them it means they’re chilling positive with negative. I get your point though and like the silk over electrical sockets as a concept. Imagine that movie pulse but the ghost is blocked by thin black silk over the electrical sockets, the exploitation practically writes itself!

@Felis Super The mechanisms are not hidden. It is just so that, otherwise, nobody had a look at them. This "old" paper did open the way of killing pathogens and cancer cells irradiating them with their own frequency. But I'm not going to do your job, Felis. Wrap yourself up and look into these topics. Someone who can show you how much you don't know about human physiology, related to electric and EM influence, is the late Harold Aspden. first do your home work and call back later.

@O. Kyklop Even if there were these receptors that were meant to pick up certain wavelengths, then that doesn't mean that all other wavelengths are harmful to the cell. It just means that the cells can't pick up those wavelengths. For example, we have receptors at the back of our eyes that detect visible light (perhaps these are the receptors the paper was talking about?), but that doesn't mean that all other wavelengths hurt those receptors. "Besides, to claim that certain waves are "harmless" it presupposes that you have a complete knowledge of the human physiology". First of all, my claim was that radio- and microwaves are as harmless as radiation can be, not that I know for 100% certainty that they can do no harm at all. Second of all, I am simply asking a question: why would our cells be significantly damaged by an extra background of radio- and microwaves (which are the waves with lowest frequency and would consequently be expected to do the least damage) when we are always bathed in higher frequencies of light (most notably IR radiation and visible light), and much with bigger intensities of them too (you can often even feel the heat that they carry). Not to mention that these long wavelength waves are not as well absorbed as other wavelengths (which is why we use them in telecommunication). If you claim that the cells are somehow harmed by these wavelengths due to some hidden mechanism that nobody has seen yet, then it's up to you to present the proof for that, not me (using a single 100 year old paper which doesn't even necessarily give the conclusion that radio- and microwaves are harmful is certainly not enough).
O. Kyklop
O. Kyklop Yıl önce
@Felis Super If you read my comments why are you insisting with things that are there explained? Whats your problem with discoveries made 100ys ago? They found those receptors. It doesn't change with time. This means, we're designed for a certain range of waves. Anything different is like hitting a pan in the middle of a Bach symphony. Besides, to claim certain waves are "harmless" it presupposes that you have a complete knowledge of the human physiology. Well. I doubt that.
