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

maybe negative ions are indirectly linked to some well-being, as ions bind to dust and pollution particles and the production of ozonize sterilizes the air, and breathing better quality air is good for the body.

talvez os íons negativos estejam indiretamente ligados a algum bem estar, pois os íons se ligam a partículas de poeira e poluição e a produção de ozonizo esteriliza o ar, e respirar um ar com melhor qualidade faz bem ao corpo.

Generally speaking positive ions are rather oxidising; negative ions are rather reducing agents. Could the negative effect of positive ions be due to their producing of oxidative stress?

I have a question about the difference about the humidity in the air when negatively charged ions are created in waterfalls and waves and thunderstorms I wonder if the ions plus humidity cause the uptick in reactions. also as a side note I worked in hotels and they use Ozone to descent the rooms after hockey teams and smokers have been in rooms over a weekend. I cannot go into the rooms when these 'ionizers' are on because they cause almost instant dizziness. weird I know.

Thanks alot. Your videos definitely help me to find answers. I never believed in astrology but now am realizing that it could be possible and scientific. The stone for ring 💍 , emitting ions, blown my mind, quite impressive. Thanks Still I have few more query. 1) does this negative ions has any impact on negative energies in house (I mean there are several story of haunted house and ghost....). Am sorry but in several means it also make me belive that this thing exists. 2) Do you think what the soul energy would be. Am curious.. Since you are more scientific and reasonable, kindly make a video or kindly make study on that. Thanks for those awesome videos, which I feel I would have never gathered knowledge without your help. Thanks. Kindly relate paranormal with science.

Why this video is focused on refuting the myths about negative ions improving mood and mental health? I think air purifier/ionizer manufacturers don't even claim that, I think they only claim that negative ions remove particulate matter including pathogens, such as bacteria and viruses, from the air. They are without any doubt very efficient in that function, that's why they are used in the hospitals. If you are to choose between the reduction of nosocomial infections vs not having 0.08 ppm ozone in the air, I think there's no question about the choice, it should be the former.

Himalayan salt lamps emit virtually NO negative ions. We have conducted tests in our lab with a salt lamp heated by a candle inside and a digital ion meter. The tiny level of negative ions have zero effect on humans standing nearby to the lamp.

You can generate negative ions with a quality generator.. byproduct small amount of ozone. Couple with earthing so you get a neutral charge in your body and more readily attract them. Egyptians knew this.. It is the meaning of Ankh energy

Maybe some of the "nay-sayers" should read, "book published during 2011 by Nobel Memorial Prize in Economic Sciences laureate Daniel Kahneman. It was the 2012 winner of the National Academies Communication Award for best creative work that helps the public understanding of topics of behavioral science stagnate instead of moving past where they are now.

This is why you need to be careful when you hear people that tell you there is studies that say something.

Hello Veritasium. If you browse thru electronic hobby magazines from the '60, you will find a staple project of the period. The name: "Negative Ion generator". There is an Americium capsule (poached from smoke detectors), affixed to a fine metal grid. The metal grid is connected to a -3,000 V power supply (made by a bunch of diodes and capacitors connected as a series of voltage doubler from main AC). A fan blows air thru the metal grid. The power supply attracts the positive ions generated by the Americium, and the fan blows out the negative ions. Electricity alone can't produce the good negative ions, but only ozone, as you also experienced. The salt lamps are a scam. The lamps made with sea salt will emit some needed iodine salt. Thanks for the great video.

if western medicine doesn't really understand what makes us alive.. and I have been a long time member of the AAAS.. science magazine once a week.. with newly published work for peer review.. and feedback from other scientists.. my father was a member so I have been reading all types of science, outside chemistry, geology and physics that I have been working on for.. 64 of my 67 years.. my father taught me the laws of motion and simple calculus when I was 3.. by describing the arc of a ball thrown from the hand.. then he threw the ball and it was exactly like he described.. I had asked what the numbers on the beautiful chart on his desk meant.. I had my sister teach me to read so I could figure it out.. my father was at the Naval postgraduate school in Monterey.. his describing of sliding scales was so clear and easy to understand.. because he understood.. very clearly.. Einstein said if you can't describe it simply.. you don't understand it well enough.. he was right.. the chart was the periodic table.. reading the letters didn't make understanding at all.... I asked.. he took me outside in the morning fog of the Monterey peninsula.. I was born in Albuquerque, so fog was new to me.. seals barking.. and my dad threw the ball and the arc was as described.. whether I used sliding contiguous values or broke the time into separate increments.. and he dropped another ball at the same time.. both hit the ground at the same time.. far out man.. . so I have been thinking about chemistry for 64 years. my brother was in bio medical engineering at UCSD.. and his group was one of two that figured out hardening of the arteries that eventually leads to myocardial infarction.. the leading cause of death among We the People.. when your heart stops, so does everything else.. but the spark of life remains.. unknown.. at least in western medicine.. the flow of energy through the body is called Qi in Chinese medicine.. it's tied up with the "magic lipids" my brother was looking for until his death in 93.. RIP Thomas.. I found them.. but .. it's unpublished information.. I have been sick.. and I had to figure out this stuff to get better.. it's very very pleasant to NOT hurt all the goddamned time.. and it is directly tied up with neurotransmitters and magic lipids.. it's not magic at all.. it's pretty simple chemistry and physics.. but if you don't know what makes our body work.. it's really just speculation.. and trying different things.. like cooking spaghetti.. throw a bit on the wall see if it sticks, kinda.. ;;☆》.. I have been reading Dr Thomas E Carew's research after his initial research on hardening of the arteries etc.. that's exactly what he was doing.. using vitamin E..or C... and trying different lipids and fatty acids.. to prevent the buildup of scar tissue in the arterial walls.... I didn't know enough organic chemistry at first.. my focus has been physical chemistry and physics.. I was a computer programmer for Raytheon Engineers and Construtors.. as a hobby, sorta.. my occupation has always been physics, chemistry and geology.. I work to support my habit.. buy equipment and pay for field work.. I didn't need a better job.. so.. no degrees.. and not one branch of knowledge.. I read to find out new things.. read everything else on the search.. so.. I am pretty good at a bunch of different disciplines.. that's exactly why I am autodidactic ... it's way more fun.. and that's why I do it.. I am a fuggin hedonist.. ;;☆》.. it's late.. I am going to bed.. not sick.. but easily tired.. it's been about 5 days.. I walked the 3rd day.. and it is finally over.. after 22 years.. good science allows accurate predictions about the real world.. the neurotransmitters that bridge the gap between nerve cells called the synapses are the foundation of Life itself.. they can be found in hempseed oil and blue poppy seeds.. gotta say blue.. the stuff in grocery stores is GMO.. with backwards proteins our body cannot see.. left hand instead of right hand.. or the reverse.. depending on how you look at it.. and each part of our body and brain has a full time, permanent pathway to and from the brain.. through the 4th opiod noceceptin.. noceceptin cells are the vaunted blood brain barrier.. and the receptors are located within the blood vessels where the nerves travel between body and brain.. the alkaloids utilize the alkalai metals in our blood to create the standing magnetic field.. cannabinoids send and opiods catch.. but what happens on one side of a magnet happens to the other at the same time.. this allows our brain to control the body in real time.. no light speed lag.. it bypasses A Einstein's assumption that simultaneous phenomenon are not possible.. north and south magnetic poles are the original entangled particles.. so we pull the finger from the hot stove before we burn.. because each pathway is permanent.. the staggered sending and receiving allows the same cells to carry both signals at the same time.. and the entire pathway is a single thing.. not dynamic.. and separate from all the others.. through the noceceptin cells.. now you know a little bit more about how our body works.. neurotransmitters are the foundation of Life itself
