“Dirty Electricity”

Cross-posted from Startled Disbelief.

I’ll begin by quoting in full a letter to the editor that I recently submitted to the Winnipeg Free Press. (Links added for citation of sources.)

On Friday, the Free Press ran an article entitled “Dirty electricity is making us sick”. In it W. Gifford-Jones argues that “dirty electricity” and “electrosensitivity” are responsible for a laundry-list of symptoms, which included “irritability”, “aches and pains”, and “foggy brain”. Academic clinical neurologist Dr. Steven Novella calls these “common symptoms of life”.

I was appalled and astounded by the poor scholarship evinced by this article. The author’s obvious disdain for the rigours of science and evidence does a disservice to science journalists everywhere.

First of all, electrosensitivity almost certainly doesn’t exist. Award-winning journalist and medical doctor Ben Goldacre sums it up nicely: “There have now been 37 such double blind ‘provocation studies’ published in the peer reviewed academic literature, and they are almost all negative, although you could argue that the evidence is unanimous. There are, to be clear, seven studies that did find some statistically significant effect for electromagnetic signals: but for two of those, even the original authors have been unable to replicate the results; for the next three, the results seem to be statistical artefacts… and for the final two, the positive results are mutually inconsistent…”

The scientific literature is rife with studies showing no adverse biological effect from low-level EMF radiation.

The author’s primary source (a Ph.D. who was instrumental in the Ontario WiFi scare a few weeks back) cherry-picks studies that confirm her biases rather than relying on systematic reviews. Her personal website directs visitors to EMF Solutions for information regarding Stetzer filters, which will “reduce the dirty electricity” in your home. The EMF Solutions site is a den of pseudoscientific nonsense, proposing that Stetzer filters are effective treatments for diabetes, asthma, multiple sclerosis, and autism. Any potential conflicts of interest between Havas and EMF Solutions remain undisclosed.

Health Canada has investigated Stetzer filters in the past. A 2006 report found that they “increas[ed] ambient magnetic field levels “, and concluded that Stetzer filters “add to the level of ‘dirty electricity’ in the house.” Note the quotation marks: “dirty electricity” is not a scientifically meaningful term.

At the end of the Free Press article the author states that all information presented “correlates to the recent World Health Organization study on cellphones that identified a need for more research into teen phone use and deadly malignant brain tumours.”

But what is not mentioned is that according to the WHO, “animal studies consistently show no increased cancer risk for long-term exposure to radiofrequency fields” and human epidemiological studies show “no consistent evidence of a causal relationship between radiofrequency exposure and any adverse health effect”. Not only that, but the exact same INTERPHONE study that Gifford-Jones quotes found “no consistent trend of increasing risk with greater duration of use”—in other words, no dose-response relationship. To use the WHO to link teen phone use with “deadly malignant brain tumours” in this way, without providing the appropriate context for the study, is not only irresponsible scaremongering, it is dishonest.

All in all, the article was a credulous, scare-mongering fluff-piece, and its publication without even token skepticism tarnishes the reputation of the Winnipeg Free Press.

This was actually the second draft that I submitted, as the letters editor requested that I cut it by 250 words. I felt that this was fair, and had condensed several of my points. But this is print media we’re talking about. I received a reply the next day, informing me that when she had said “by at most 250 words”, she had meant “to at most 250 words”.

In any event, this is what they are planning to print:

I was appalled by the poor scholarship in Friday’s “Dirty electricity is making us sick”. The scientific literature is rife with studies showing no adverse biological effect from low-level electromagnetic fields (EMF). “Dirty electricity” is a scientifically meaningless term.

Electrosensitivity almost certainly doesn’t exist. Thirty-seven double blind studies published in the peer reviewed literature have been nearly unanimously negative. Of the seven that did find some statistically significant effect for electromagnetic signals, two could not be replicated, even by the original authors; the results of three are regarded as statistical artefacts, and in the final two the positive results are mutually inconsistent.

Magda Havas cherry-picks studies that confirm her biases rather than relying on systematic reviews. She endorses EMF Solutions, which sells Stetzer filters, asserting they can be used to treat diabetes, asthma, multiple sclerosis, and autism. (Source: magdahavas.com, emfsolutions.ca) Health Canada found that Stetzer filters “increas[ed] ambient magnetic field levels ” and that they “add to the level of ‘dirty electricity’ in the house.” (Source: Health Canada CCRPB)

The article states that the WHO “identified a need for more research into teen phone use and deadly malignant brain tumours.” This is irresponsible scaremongering. The article does not mention that the WHO states “no adverse health effects have been established for mobile phone use”. (Source: WHO)

The article was a credulous fluff-piece, and its publication without even token skepticism tarnishes the reputation of the Winnipeg Free Press.

Terse, isn’t it?

I managed to squeeze most of what I wanted to say into the first letter, but in case you’re curious, here are some links to additional articles published on the subject:

Award-winning Podcaster and Science Enthusiast Brian Dunning:
Electromagnetic Hypersensitivity: Real or Imagined?

Academic Clinical Neurologist Dr. Steven Novella:
Banning WiFi from Schools

The author of the Free Press article, W. Gifford-Jones (apparently an M.D.), tells us that he “discovered it’s easy to get fooled by dirty energy if you’re not an electrical engineer.” Irony notwithstanding, it occurred to me that I’m not an electrical engineer, so perhaps I’d been fooled. I turned to Magda Havas’ website for clarification. Here’s what she had to say:

The term “Dirty Electricity” is often used to describe the type of power that originates from our generation stations. Hydro electric and solar are considered to be “Green” sources of power where coal is considered to be “dirty” because of the air pollution that is created.

Okay, I’m with her so far—although hydroelectric dams aren’t exactly environmentally neutral. But that doesn’t really seem to correspond to the article’s description. Let’s see if there’s any more…

“Dirty Electricity” can also be used to describe electric power that has become corrupted by our use of modern appliances.

Oh. Well that makes sense.

Items such as CFL bulbs, cellphone transmission antennas, power supplies for portable computers, cell phone chargers, dimmer switches, variable speed fans and many other electronic devises that require a transformer to convert the voltage will “dirty” the electricity that enters our home. This form of dirty electro-magnetic fields (EMF), is invisible to the eye, but has a biological effect on the human body and has been associated with a wide variety of illnesses.

And that’s the end of her explanation. Variable-speed fans make the electricity dirty. It’s all the transformers’ fault. (Presumably it’s the Decepticons that are the problem—the Autobots wouldn’t do that to us.)

On a side note, I was curious as to the source of Gifford-Jones’ contention that “during the height of the Cold War, they [Soviet scientists] secretly bombarded the U.S. embassy in Moscow with microwave radiation, causing radiation sickness in American staff.” Although no source was cited, Google is your friend: I traced it to a news article hosted on educate-yourself.org, a fairly disreputable conspiracy-mongering site, and from there to a paper entitled PRACTICAL GUIDELINES To Protect Human Health Against Electromagnetic Radiation Emitted In Mobile Telephony on getpurepower.ca. It seems that this bombardment did actually occur, however I find the contention that it caused radiation sickness puzzling, as radiation sickness is caused by ionizing radiation. Microwaves are non-ionizing, and are found on the opposite end of the electromagnetic spectrum. If anyone more familiar with the subject is interested in chiming in, please feel free.

A friend of mine remarked that the article reminded him of some of the crazy things Thomas Edison said during the War of Currents.

I’ll conclude by quoting, in its entirety, the first (and currently only) comment found on the digital version of this news story.

It has now become political to whether or not Cell Phones, Power Lines etc are or are not responsible for Health related problems.

First off, every one who thinks they do, will all agree that these emit a HARMFUL energy. “WRONG”

Okay, I’m with you so far. Bring it home!

It is NOT the energy emitting that is the problem and “there is a problem”.
It IS, IS, IS the ENERGY that these absorb, robbing cells of the body of this needed energy!

Hat tip to Robert McGregor, who directed me to this story (and who apparently reads the newspaper).


Edit: The Register (a UK technology news source) has recently published an excellent and tangentially-related article on the subject of Belly Armor. You can check it out here! Thanks to Grant Rogerson for the link!

  1. Electrical sensitivity is recognized by the governements of Sweden and England. it is indeed real.
    I’m electrically sensitive, and so is at least 3% of the general population. In my case, symptoms included life-threatening cardiac irregularities as well as numbess on left side of body, pain in left side of head and extreme insomnia. $18,00 worth of medical tests found no cause for any of these symptoms. All the symptoms disappeared after we installed Stetzer filters. Health Canada, I am sorry to say, is too closely associated with industries that create the harfmul frequencies.
    After I recoverd my health I created a Web site to educate the public about both the health and political issues involved. I invite o to do some reading there: http://www.LifeEnergies.com.
    Dr. Havas and Dave Stetze both have my greatest respect. They each work countless hours to help mankind. Magda makes not a penny associated with the Stetzer products and it will be some time before Dave Stetzer recoups the money he had to spend to make these available to the public. I know him pesonally, and the story of how he came to help ceate the filters when he discovered the health damage being done by “dirty electicity.” He is definitely not in it for the money.
    If not for the Stetzer filters, I would not be writing this letter. I’d be dead.

    1. Electrical sensitivity…

      This is a testable claim, and it hasn’t met the burden of proof.

      …is recognized by the governements of Sweden and England.

      That is somewhat irrelevant, a government recognizing something as a handicap does not say anything about the scientific merit of a claim.

      Health Canada, I am sorry to say, is too closely associated with industries that create the harfmul frequencies.

      Again, that does not address the science of whether this is a real phenomenon.

    2. “If not for the Stetzer filters, I would not be writing this letter. I’d be dead.”

      It is very sad that you believe this.

      “He is definitely not in it for the money.”

      It is also very sad that you believe this. Of course he’s in it for the money. This filter is a simple capacitive reactance filter. You could get the same effect (none) by connecting a 20 micfoFarad motor start capacitor to your household outlet.
      Did this filter cost more than $10?

  2. If you have any evidence to present, Shivani, I would be happy to examine it. (Within reason—I have a job and a family, so I’m not going to spend days on end poring through PDFs.) What I’m interested in is peer-reviewed research that is double- or triple-blind and is properly controlled. Unfortunately, your personal experience (while distressing) doesn’t qualify. I’m sorry that you have had such a rough time of it, and that doctors were apparently unable to help you, but sometimes in science the answer is genuinely “I don’t know”.

    Your dismissal of Health Canada as “too closely associated with industries that create the harfmul frequencies” to be trusted sounds suspiciously like conspiracy-mongering. I would recommend examining research based on its merits.

    I’m also interested in a citation for your claim that 3% of the population (of the planet? the country?) is electrosensitive.

  3. The government of England also recognizes the concepts of Sovereignty by Divine Right and the medical benefits of homeopathy, so…yah.

  4. not to burst any bubbles…. but I personally know Dave Stetzer and he IS in this for the money and quite frankly from what I have seen he is a CROOK…. Price out any capacitor and resistor (which is all his “filter” is in a case) and the parts are practically nothing (couple dollars) but he charges $35+ for a supposed “filter” and ships his crap in from communist China! Can anyone say Snake oil? Capacitors can clean up some transients on the voltage and have been used on electric motors for years….. but with the proper equipment one can see how these transients go from the voltage wave form on to the current waveform (with his “filters”)…. AND, with wiring issues or errors in a home can add insult to injury….. !!!
    Then, take the supposed GS meter ….. plug more than one in at the exact same time on the exact same power strip and watch all the numbers go all over the page -they don’t even read accurately when referencing to themselves! Good quality control. Can anyone say Snake oil? But, of course, one must use HIS meter to determine if your house is “fixed”. Someone is laughing all the way to the bank!!!! And, it’s not the consumer! Claiming it takes at least 20 “filters” to clean up a house, when some houses only take 4-5 -what a SCAM! How can he have such blind followers???
    Havas not making a penny???… prove it! She knows all about surface body voltage and refuses to discuss this…. Along with how cheap and inexpensive the parts are to ground to earth along with the benefits…. All she does is push the Stetzer crap claiming in her studies that they are the cats meow….

    There are differing views on emf, magnetic fields, electric fields etc. etc….. time will only tell. Maybe some folks get help, and others don’t. But either way, selling crap like this to innocent caring folks without telling the whole story and facts is way worse than what any Utility or Power company is supposedly doing to the end consumer!

    The article above by Mr. Newman puts this into a much better perspective!
