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:

You have one of the kindest energies in addressing these topics I've seen. That, in itself, is quite admirable. We always need more civil discussions about the wonderful reality we all inhabit. The sum total of our present knowledge is still the tip of the proverbial iceberg! Human curiosity is so great that the exploration will really never cease.

My salt stone's bulb broke and I replaced it with an LED bulb, which doesn't get hot. Good to know that it doesn't matter.

We've all been lamp scammed!

Now I need to look for more things studying these salt lamps..

"Are you an Ion experct"
"I've been studing them for 55 years"

That's a real expert. Doesn't want to say yes because there's always more to learn. Just tells you his credentials and lets you decide if you think he's an expert.

#lastpass thank you guys! I will sign up now.

I like salt lamps because of the orange-ish color they have when turned on. They're just neat, in my opinion. Not because of the 'negative ions' they apparently are supposed to (but don't) create.
You should take a walk outside haha

Why dose it sound like u are playing halo reach music over the video

That scientist person sounds creepy as hell when talking about the ozone lol.

It's funny, you said "Are negative ions good for you? Normally I'd dismiss such a question", which is literally the reason I dismissed this video whenever it showed up on my recommended page. I've seen videos like these, I always thought annoyedly, it's just gonna be some spiritual dude trying to convince me to buy magic stones or something like that. Cuz that's what the video looked like.
It was framed as a "let's talk about healing stones and air energy" type of video, when really it was "yeah so people keep talking about these ions and stuff, and so I decided to bite and see what all the fuzz is REALLY all about so you don't have to bother doing that"

Now... What about Ion Cannons launched into space? :D

Well the salt lamps may not work as intended, but they sure look cool. Maybe the ambiance they add to your abode will improve your mood/feeling of happiness.

Thank you for the video! I have two questions though. If you have a fountain at home, that would increase somehow the level of negatively charged ions right? My second question is about the air purifier that creates negative ions and ozone at the same time. Is this true for all air purifiers with an ionazer?
Steve Frayne
This is a great video. Good job!
I thought these lamps we for aesthetics.
There are infinitely more positive benefits going to the waterfall, just by the fact that you are removing yourself from all of the bombardment of frequencies from all of our technology. Which is documented science. No matter how much the big corporations want to say it's all fine and go about your business.
I didn't even know that I missed veritasium video untill I watched "how video becomes viral" and I looked for this.

Fascinating! Thanks for making my salt lamp worthless...
The LastPass link doesn't work.

This indeed is a good video.
