I know it sounds crazy but the more I dug into this question, the crazier it got. I have been obsessed with this topic for the past several weeks and I hope you'll agree the video reflects the incredible amount of passion that went into making it.

Please, if you like this video, share it with your friends. Share it with someone who has a salt lamp or really loves waterfalls. Or someone who is a super skeptic...

This is an unpaid post because of the significant sponsor.

Are Negative Ions Good For You?

Do negative air ions improve mood, anxiety, depression, alertness? Part of this video was sponsored by LastPass, click here to find out more: http://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: http://www.cce.caltech.edu/people/jesse-l-jack-beauchamp http://beckmaninstitute.caltech.edu/eac.shtml If you want to dig into the research on negative ions yourself, I suggest starting with the review studies: Air ions and mood outcomes: a review and meta-analysis.

Would be happy to pay for this one. Cheaper than going out and buying a useless lamp.

Thanks for this useful video. Maybe placebo effect helps the people who find any benefit from the salt lamp.

Well I was given one of these lamps, does create nice diffuse light quality which is nice at night.

Wonderful ... as usual. I was a little surprised you used the terms "alpha, beta, and gamma rays" which are more than a little archaic. I often also decry the use of atom graphics that are hopelessly out of scale and/or show orbiting electrons. This is a hundred year old model at this point which has been discredited, but the continued use of the image supports this inaccuracy.

Veritasium: these things are basically useless... No one: Me: *buys 4 salt lamps immediately*
