About 15 years ago, a new kind of home electric meter with special capabilities came onto the scene, promising consumers savings on their electric bills, and convenient access to information about their electricity usage. These new meters were named smart meters (technically called advanced metering infrastructure - AMI), and were considered to be an economical and functional upgrade to the digital and analog meters that were previously used on all residences and buildings. Unlike older digital and analog meters, which required being manually read once a month by a utility company employee, smart meters transmit this information wirelessly, in the form of radio frequency electromagnetic fields.

If the creators of smart meters simply allowed the 6-millisecond pulse of an information carrying radio wave to be sent from the meter on each residence to the power company once a month, to eliminate the cost of having to physically send a worker to each residence to take meter readings, they could have stopped right there and potentially avoided the myriad of problems associated with smart meters we are seeing today. However, visions of the smart grid of the future, and of automated homes, compelled them to reach much further.

Of course, just like 5G, smart meters are advertised to mainly benefit the end user, but the truth is that the user is ultimately put at risk in several ways, and the biggest benefits are reaped by the power companies and the government.

Smart meters boast the recording of “real time information on power usage”, so that the customer can monitor their own electricity usage and see the costs in real time, to adjust power usage and save money. The truth is, people’s electricity costs have uniformly gone up, not down, since the installation of smart meters. The verdict from electricity consumers after more than a decade of smart meter use is that there have been no benefits to them, and that the majority of people do not have any interest in seeing a breakdown of their energy usage. It seems that people are generally already aware of how they are using electricity, will choose to continue using electricity the same way they were before, and are more than happy to pay for it.

Besides having no significant benefits to the end user, smart meters have brought widespread concerns over health, safety and privacy.

Health concerns revolve around the pulsed radio frequency radiation that smart meters rely on to transmit wireless information between each meter and the utility company’s headquarters. This is a similar type of non-ionizing radiation used by cell phones, cell towers and Wifi routers, all of which have been extensively studied and found to be dangerous to human health. However, smart meters in particular have a unique exposure risk, due to several factors:

  • close proximity to the living areas in a home (sometimes just several feet from a sleeping area)
  • the sharp, spiked radio frequency pulsations used to transmit the signal
  • how frequently the signal is transmitted (up to 190,000 times per day!)
  • dirty electricity created by the smart meter communicating with in-home appliances

Smart meters are often installed on the outside of the wall of a main living area or bedroom, where residents spend a lot of time. In addition to the omnidirectional, pulsed radio frequency field that’s often emitted many times per minute, the meter also produces a strong magnetic field that can radiate several feet into the house. To send data to and from the power company, this sharply pulsed RF wave is often produced every 3 to 7 seconds, and even up to 190,000 times per day.

Although utility companies claim that smart meters are within FCC guidelines regarding safe levels of RF exposure, this is not true, because what is being measured is the average reading, not the peak reading. This means that the incredibly strong RF spikes you are actually exposed to are being statistically averaged down to much lower levels by factoring in every single second where there is no RF output at all. If one were to measure the strength of the actual RF spikes, they are often 200 times the strength of the documented “average”.

Daniel Hirsch, Professor of Nuclear Policy at the University of California-Santa Cruz, calculated that the whole-body cumulative radiation exposure from wireless meters is 100–150 times higher than cell phone exposure. The graph below, from Professor Hirsch’s report, shows the cumulative bodily RF exposure of smart meters (at a distance of 3 feet), compared to cell phones, microwave ovens, Wifi routers, radio/TV broadcasts, and a smart meter from a further distance.

This graph shows why close proximity to a smart meter can be devastating to health. Cecelia Doucette, a technology safety educator and the director of Massachusetts for Safe Technology, states that, “These meters are installed directly on our homes and elsewhere with no informed consent, and people unwittingly sleep or spend time on the other side of the wall and get very, very ill.”

However, the risks of health harm from a smart meter on your home are not negated much by staying further away from it. This is because the smart meter actually communicates with your in-home electrical appliances every couple of seconds, to record specific appliance usage. This happens through the electrical wiring of your house. The meter uses something called a switched mode power supply to change the voltage every time it moves between the meter and the electrical line, and since it does this every couple of seconds, it generates an enormous amount of what is known as “voltage transients” or “line noise”, now more popularly known as dirty electricity.

Dirty electricity is a spiky, pulsed, highly variable electrical current that rides through all the circuitry of a building, and radiates a few feet into every room, near where the electrical lines run behind the wall, as well as behind each electrical outlet. It can have devastating health effects.

Unfortunately, this means that if you are lucky and persuasive enough to convince the power company to shut off the RF signal emission to and from your smart meter, or to replace it with what’s being called an “Opt-Out meter” in some places, you are not eliminating the dirty electricity problem at all. The smart meter is still actively collecting detailed data from all your appliances; it’s just not sending it via RF to the power company anymore, so only one part of your problem is solved.

This survey and report on the health effects of smart meters compiles data from a questionnaire filled out by 201 people who claim that smart meters have damaged their health. Some of these people already considered themselves electro hypersensitive (EHS) before their smart meter was installed, but the smart meter made it much worse. Others did not consider themselves EHS before the smart meter, but state that the meter exposure has made them hypersensitive to all EMF sources, including their cell phone and computer, which many did not have issues with previously.

The report also summarizes the most common symptoms the survey participants experienced from smart meter exposure. The most commonly reported symptoms that were either new or worsened from exposure were ear ringing, headaches, difficulty concentrating, insomnia, fatigue and heart arrhythmias. 42% of the survey participants actually developed their symptoms prior to the knowledge of the presence of smart meters, and before they had any awareness of RF radiation danger, which rules out psychosomatic factors.

Safety and privacy issues of smart meters

These high-tech meters are not just a risk to your health, they also come with safety and privacy issues. They have become notorious for exploding and causing house fires. EMF electrical consultant Cindy Sage explains that smart meters can create an over-current condition on the wiring and produce heat that the neutral cannot properly handle, which can lead to fires. This stress on the wiring is caused by the short, intense bursts of very high intensity radio frequency emissions, which can spike the voltage too high.

Other potential causes of smart meter explosions are incompatibilities between the old meter base and the new meter, loose connections, and defective equipment. So far, hundreds of thousands of meters have been replaced either because of an actual explosion or fire caused by the meter, or meters that were suspected to be defective and potentially unsafe. In 2015 in Stockton, California, a truck crashed into a utility pole, which caused a power surge that resulted in about 50-60 smart meters exploding and catching on fire at residential homes. Although power companies publicly deny that smart meters carry a risk of explosion and fires, they have installed voltage and heat sensors on the meters as a precautionary measure, for monitoring purposes. Actions speak louder than words.

Another major issue with smart meters is related to privacy and security. The meters collect extremely detailed data about your in-home electricity usage, including which appliances are used, how often, and when. Then this data is transmitted wirelessly, and wireless data is much easier to intercept and hack than a secure wired connection. This means that anyone with some tech know-how and bad intentions can discover what you’re doing and when you’re doing it, and may be able to use that information to harm you.

Also, it’s becoming widely known that utility providers can collect and sell your power usage data to third-party companies, as long as they withhold identifiable personal information like your name and social security number from these companies. Of course, they tell you this is for your benefit, so that they can “serve you better”. They make a lot of money selling this information, so it makes sense that we should be seeing considerable reductions in our electricity bills if we have smart meters, since the utility providers are making money from our personal usage data. Then why have electricity costs only gone up?

One of the most concerning aspects of the two-way data transmission of smart meters is the fact that our meters are now remotely controlled from the utility headquarters. This means they can turn our power off anytime, for any reason they deem necessary. If we miss our bill payment due date, they can shut off our power instantly right from the source, instead of having to send a service technician to our house to do it manually. They also have the power to control our usage, and it’s not unrealistic to imagine a so-called energy crisis moment where they decide that it’s best for the collective that our thermostats stay within a narrower range on an exceptionally cold or hot day, when the power grid is extra busy.

Can you get rid of your smart meter?

Utility companies have been busy for more than a decade replacing as many older analog and digital meters with smart meters as possible, so chances are high that you currently have a smart meter installed on your house. Can you get rid of it? If so, how do you do this, and what are the potential downsides and complications of doing so?

It depends on where you live. Since the initial rollout of smart meters, due to widespread opposition from individuals, several states have enacted statewide opt-out policies. Other states have unique policies, or case-by-case opt-out programs. State legislatures are being confronted with this issue more and more frequently, so even more opt-out policies are being considered.

You can look up the details of the smart meter opt-out policies of your state here:https://www.ncsl.org/energy/smart-meter-opt-out-policies

Unfortunately, most states that do allow opt-outs charge a one-time fee, as well as a monthly fee, to complain that you not having a smart meter is inconvenient for them. The fees vary considerably by state, ranging from single digit monthly fees to hundreds of dollars in one-time fees. Iowa now allows residents to opt-out and keep their analog meters at no charge.

New Hampshire, as usual, sets the precedent as the state to look up to: not only is there no charge to keep your old meter, but they actually have an ‘opt-in’ policy instead of opt-out, where utility companies must obtain written consent before they can install a smart meter on a home or business.

Pennsylvania, however, has a statewide requirement that utility companies deploy smart meters across their entire service area, and customers are not allowed to opt out for any reason.

The main issues with these fees concerns electro hypersensitive (EHS) individuals, and the considerable threat that smart meters pose to their health, functionality and well being. Ed Friedman, a Maine resident who filed a disability/discrimination lawsuit against a Maine power company for not agreeing to waive fees to accommodate his disability, states that his doctor recommends that he should not be exposed to any RF radiation in his home. The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities from accessing government programs and services. Because of his debilitating sensitivity to RF radiation, he is being forced to pay monthly fees to use an analog electric meter that doesn’t aggravate his condition. Disabled people often have budget constraints, because they are often not able to work, so these monthly fees can be the breaking point for many of them.

Children’s Health Defense has been working towards establishing more freedom of choice when it comes to smart meter exposure. They wrote up a template letter that you can easily send to your state legislators in support of utility meter choice, and are urging everyone concerned about this issue to take this simple step towards more awareness and choice:

Tell Your State Legislators to Introduce/Support Utility Meter Choice

Some states, like Texas, allow you to request to have two-way meter communication turned off, which will solve the issue of RF radiation exposure, and will minimize the privacy and security concerns of wireless data transmission. However, as mentioned earlier, it may not affect dirty electricity exposure or meter safety issues at all.

The Smart Meter Education Network is an excellent resource for Michigan residents, but also has information that should be very useful for anyone wanting to learn more about the dangers of smart meters, and how to replace yours with a safer alternative.

Can you protect yourself from smart meter radiation?

If you currently have a smart meter, and are not able to get rid of it because of the expense involved, or limitations in your state laws, are there ways to protect yourself from its harmful radio frequency radiation and dirty electricity?

Yes! There are a few things you can do. First, make sure your smart meter is as far as possible from your main living area, and especially your bed. If your bed is on the opposite wall of your smart meter, it would be a good idea to move it somewhere else. Some people like to use a metal mesh smart meter cover to create a Faraday cage around their meter, which will block most of the measurable RF radiation emitted by the meter, but will still allow enough signal to get through to send data to the power company. You could also use dirty electricity filters on your home electrical outlets to reduce the intensity of the line noise/voltage transients caused by the meter.

Those options will likely offer some relief by reducing exposure, but if you have a smart meter on your home, we strongly recommend that you use an appropriate strength home Blushield device, which will create a stronger, biologically coherent scalar field that protects your body at the cell level. This is an effective way to internally mitigate any EMFs that are not possible or practical to remove from your space. The chaotic, stressful field produced by the smart meter’s pulsed RF, magnetic field and dirty electricity can trigger the body to mount an immune response, like it’s attacking an invader that’s never defeated. Adding a Blushield field to that space acts like a bubble of protection for your cells, calming the overactive immune response and surrounding you with a nature-based frequency field.

The home Blushield device you choose should depend on your overall EMF exposure, considering all sources like smart meters (yours and your neighbors’), Wifi routers, cell phones, smart devices, nearby cell towers, dirty electricity and more. For a straightforward and easy way to determine the best home and portable Blushield models for your needs, please read our Blushield Product Guide.

The Science of Stability: Why Powered EMF Protection Outperforms Passive Devices

In our increasingly hyper-connected world, the conversation around Electromagnetic Fields (EMF) has shifted from "if" we should protect ourselves to "how" we should do it. As we surround ourselves with 5G towers, Wi-Fi routers, and smart appliances, the market has been flooded with solutions ranging from stickers and crystals to sophisticated electronic resonators.

However, not all protection is created equal. To understand why some methods fail where others succeed, we have to look at the physics of signal dominance and the biological need for a coherent reference.

The Passive Problem: The Limitation of "No Power"

Passive EMF protection products such as shungite, specialized stickers, or unpowered pendants operate on the principle of attenuation or local field alteration. While these materials may have unique molecular structures that interact with frequencies, they face a fundamental "physics wall": they lack an internal energy source.

Without power, a device is purely reactive. It cannot create a signal; it can only respond to the signals already present in the room. This leads to three critical failures in a modern environment:

01. Lack of Signal Dominance

For the body to prioritize a "healing" or "balancing" frequency over the chaotic noise of a Wi-Fi router, that frequency must be dominant. Passive devices are essentially "whispering" in a room where the EMF environment is "shouting." Because they cannot project a field, their influence is limited to the near field usually just a few millimeters or inches from the object.

02. The Trap of Ambient Fluctuations

Passive devices are at the mercy of their environment. If the ambient EMF levels spike (like when you take a call or download a large file), the passive device has no way to scale its interaction. It cannot maintain a structured reference signal because it is constantly being "pushed around" by the very frequencies it is meant to harmonize.

03. No Timing or Pulse Control

Biological systems are highly sensitive to rhythm and timing. Active EMF protection often uses specific pulse-width modulation to mimic natural Earth frequencies (like the Schumann Resonance). Passive devices have no "heartbeat"; they lack the circuitry required for timing control, meaning they cannot provide the rhythmic consistency the body needs to stay grounded.

The Active Advantage: Establishing a Coherent Reference

Powered, dynamic signaling systems represent a different paradigm of protection. Instead of trying to block or absorb radiation which is nearly impossible in a modern home these devices focus on Active Resonance.

Building a "Safety Bubble"

A powered device uses a dedicated power source to emit a consistent, coherent, and structured electromagnetic field. Because this signal is generated internally, it is not dependent on the noise of the room. It creates a stable "reference point" that remains constant regardless of how many devices are active in the house.

Conclusion: Why Power Matters

In the quest for wellness in a high-tech world, we must choose tools that match the scale of the challenge. Passive materials certainly have their place in history and personal practice, but they lack the "active voice" required to compete with the high-output infrastructure of modern telecommunications.

If the goal is to create a true sanctuary a space where biology can rest independent of the changing electromagnetic tide a powered, dynamic system is not just an upgrade; it is a necessity. By establishing a dominant, coherent reference signal, we provide our bodies with the stability they need to thrive in the digital noise.

Did you know that your smart phone settings include a section that advises usage habits to reduce RF (radiofrequency) exposure?

This advice is included even though all smart phones proclaim that they are in compliance with the government’s SAR (Specific Absorption Rate) safety limits.

If the radiation emitted by cell phones was truly safe, why would they bother to tell you ways to reduce radiation exposure? Could it be because the SAR limits are outdated, and only address thermal (heating) effects of non-ionizing radiation exposure, and ignore the mounting evidence of harm from non-thermal mechanisms?

Let’s dive into this revealing topic that most people are unaware of, even though the majority of us are smart phone users.

You can check your own smart phone now. If you have an iPhone, just go into the Settings, then click General, and there should be a section called Legal and Regulatory. If you click that, and scroll all the way down, there should be a section titled RF Exposure. This may look slightly different on Android phones (like Samsung and Google Pixel), but you will find something similar if you investigate.

This section should display the results of the SAR test for your phone model, which of course will be within the “safe limits” for radiofrequency radiation exposure. If you have an iPhone, you may see something like this:

"To reduce exposure to RF energy, use a hands-free option, such as the built-in speakerphone, headphones or other similar accessories. Cases with metal parts may change the RF performance of the device, including its compliance with RF exposure guidelines, in a manner that has not been tested or certified."

Why advise reducing exposure, if the exposure level is already safe?

A Google Pixel phone we looked at, which tested at well within the SAR safety limits, even included this statement: “Keep the device away from your body to meet the distance requirement.”

What distance requirement? The SAR tests state that when the phone is placed directly against the head, or within 5mm of the torso of the body (to simulate the phone being in a pocket with a thin layer of clothing in between the phone and your skin), that you are “safe”, according to standard tests.

The Samsung S21 smart phone fine print informs that their SAR distance for safety is 15 millimeters, which is equivalent to more than half an inch. Most people place their cell phones directly against their head when making calls, as they have never been informed to do otherwise. If a Samsung S21 phone user is making calls in this way habitually, the company’s own recommendation implies that the user may be exposed to unsafe levels of RF radiation on a regular basis. Yet, this is not widespread knowledge, and is only in the fine print that most people don’t know exists!

Samsung also states, “Specific Absorption Rate (SAR) certification establishes a minimum recommended distance from a person’s body for safe operation of RF-emitting devices. Body-worn operations are restricted to belt-clips, holsters or similar accessories that have no metallic component in the assembly and must provide at least 1.5 cm (3/4 in.) separation between the device and the user's body.”

Did you ever hear any of this from a cell phone TV commercial or online advertisement? We certainly haven’t.

Pharmaceutical drugs are legally required to list their “fine print” of potential side effects, even on TV commercials. Why aren’t cell phone companies required to at least give you a brief warning about RF radiation exposure before you purchase their products, and suggest ways to reduce exposure?

It’s also important to note that having Wifi and Bluetooth enabled on your smart phone will significantly increase the RF radiation output of the device. Many people keep both of these turned on continuously or at least periodically, and do not consider the additional radiation exposure they may be getting, which may often be higher than the SAR safety limits.

The Specific Absorption Rate (SAR) limits are too high, and not healthy

Cell phone companies and the FCC seem to enjoy splitting hairs about the details of the SAR limits, and are quick to point out that the SAR test scores that phones list are at their maximum radiation output, implying that most usage is going to fall at far lower levels than the output listed on the test results.

If we’re going to argue at this level, it’s good to know that many phones may not actually be compliant at all, according to independent tests performed in 2019. If the cell phone company itself performs the tests, and the results can’t be replicated independently, then can we trust them in the first place?

However, let’s move past this type of nitpicking for now, and talk about why the SAR limits are inherently flawed and dangerous in the first place.

As stated earlier, the Specific Absorption Rate is only testing the thermal effects of cell phone radiation, meaning how much it heats localized tissue. That is the only mechanism of harm that the telecoms and FCC are willing to admit to. For a minute, let’s pretend that this is the only mechanism of harm. Even if that were true, there are significant flaws with the SAR safety limits.

The SAR safety limit was originally set in 1996 – 30 years ago. They modeled the body proportions of Army personnel, who are generally large, fully grown men, often around 6 feet tall and 200 pounds. This model does not come close to representing smaller and more developmentally vulnerable populations like children, teenagers and pregnant women. Grown men are generally the most resilient category of humans to toxic exposures of all types, whereas babies, children and developing embryos and fetuses are the most fragile. Babies and children have smaller heads, thinner skulls and rapidly developing brains that are highly vulnerable to harmful environmental influences, including wireless radiation.

The SAR rate that was set in 1996 has not been updated at all over the past 30 years, even as new cell phone technology and usage habits have evolved seemingly at light speed. The maximum distance that a phone could be tested at to achieve compliance was up to 25 millimeters, which is much further from the body than where today’s phone users keep their phones. The 25mm distance was set because in the ‘90s, people often carried their flip phones on belt clips, which were about an inch away from their body. Almost no one uses belt clips anymore, and most often, the phone is carried in a regular pocket, which is generally only 2mm away from body tissue, especially vulnerable reproductive organs like the ovaries and prostate. Guidelines have not been updated to reflect changing habits of users, nor have users been adequately warned of the potential harm of keeping their phone that close to the body.

There is also no consideration for long term exposure. Regulations are set based on immediate effects, with no thought for the many decades of consistent cell phone and other wireless radiation exposure that most modern people, especially young people, will experience in their lifetimes.

Regulations also do not acknowledge the fact that people generally no longer carry just one wireless device with them, but use multiple RF emitting devices regularly: cell phones, tablets, Bluetooth speakers and headphones, vehicle GPS devices that connect to Bluetooth, smart devices that connect to your smart phone, and much more. All of these sources multiply our RF exposure to levels that are currently unknown, and unacknowledged by official government and telecom industry sources.

We are stuck with the ancient 1996 SAR guidelines, which were created in a vastly different technological world than the one we live in today.

Thermal effects are not the only concern with wireless radiation

Lastly and most importantly, the SAR safety standards are based on the (proven erroneous) assumption that the thermal effect is the only way that cell phones can cause harm.

In the early 2000s, the National Toxicology Program, an arm of the U.S. Government’s National Institutes of Health, performed the largest, longest study on the health effects of cell phone radiation that had ever been done up to that point. Their stated intention for the study was to find out whether there were non-thermal health risks to cell phone use, since the only safety guidelines that existed at that point were the SAR safety limits, which were only based on thermal exposure risks.

This is an entire story in itself, but suffice to say that considerable harm related to cancer and DNA damage were found – results that were surprising to everyone involved in the study. After a brief period where a peer review panel of experts declared that the study was well performed and showed clear evidence of cancer and DNA damage, the government agencies involved subsequently pivoted in their opinion and decided that the study was NOT relevant to human exposure. If you haven’t yet read this whole story, you will want to, as it shows beyond any doubt how egregiously biased the United States government is towards siding with the telecom industry.

$30M National Toxicology Program Study Shows Cell Phone Radiation is Carcinogenic (full story)

The most important thing to realize is that science shows that non-ionizing radiofrequency radiation, at below-thermal levels, can be harmful to health. Whether or not a mechanism has been definitively recognized that accounts for this non-thermal harm, the harm itself has been documented in hundreds to thousands of studies, many of which you can read about here.

If you’re interested in purported mechanisms of non-thermal harm, the most probable theory at this time involves the voltage-gated ion channels of the body, and how external electrical signals trigger these highly sensitive voltage-mediated channels to flood various minerals (especially calcium) into the cells, triggering a cascade of unintended and unwanted effects. This mechanism has been extensively studied by Dr. Martin Pall, and has been discussed in at least a dozen of our other articles.

Don’t fall into the trap of blind trust – protect yourself

Ignorance of the truth won’t protect you. It is the fault of the government and telecom companies that it isn’t common knowledge that your daily wireless device usage may cause health issues over time. However, it is your responsibility to educate yourself, and to protect yourself as well as you can. Most people are not going to give up their cell phones entirely, but there are things you can do to significantly reduce your exposure:

  • Never carry your cell phone in your pocket, or anywhere against your body, unless it’s turned off, or set to airplane mode.

  • Never sleep with your cell phone near you, unless on airplane mode with Bluetooth and Wifi disabled, and even then be sure it’s at least a few feet away – definitely not under your pillow or near your head.

  • Never hold your phone up to your head when you talk. Instead, use speaker phone or an AirTube headset (which has a tube of air instead of wires all the way to your ears) to make calls.

  • Limit your children’s cell phone and tablet exposure, and be cautious during pregnancy and around babies.


To protect your body from any remaining radiation exposure, since you can’t control a lot of the RF exposure sources around you, be sure to protect your home with a stationary Blushield device of the appropriate strength for your overall EMF exposure levels, and carry a Blushield portable device with you anytime you’re on the go.

Blushield devices were demonstrated in a 2023 clinical study to calm overactivation of the voltage-gated calcium channels back to normal levels – VGCC overactivation is widely thought to be the primary mechanism of harm from EMFs, as we touched on earlier. A variety of other statistically significant health improvements were recorded, as well, showing that even if the mechanism of harm from non-thermal EMFs is more complex and nuanced than we currently know, that our EMF protection technology is broadly beneficial in regulating physiology back to a healthier state.

Why I ultimately chose active and dynamic field signalingMy name is Brandon Amalani and I have been running Blushield.com for nearly ten years.People regularly ask me about passive EMF protection devices and whether they are reliable or effective at protecting biology from man made electromagnetic exposure. That question comes up more now than ever, especially as passive devices have become extremely popular in recent years. I want to be very clear from the beginning that this article is not an attack on anyone or any company. It is an honest attempt to explain what I have learned about physics, biology, and signal behavior after a decade of working directly in this space.I originally got involved with Blushield after personally exploring many of the options available at the time. Most of what existed were passive EMF devices such as stickers, pendants, resonator chips, cards, and other non powered products. There were also shielding materials, grounding strategies, and constant single frequency generators. I tested all of these myself and spent a lot of time learning where each approach worked and where it clearly did not.That was about ten years ago. Since then I have worked closely with inventors and researchers in the electro therapy space and continued my education across multiple disciplines including cold plasma technology, photobiomodulation, PEMF system design, cellular biology, nutrition, and herbalism. Having this cross-disciplinary perspective has been critical in helping me understand how the human body functions as an electromagnetic system and how it interfaces with both natural and man made fields.Over the years I have noticed a shift in how passive EMF devices are discussed and marketed. Many educators and companies have moved away from older language like depolarizing EMF or harmonizing waves, and are beginning to use more nuanced terminology around coherence and biological signaling. That shift is a step in the right direction. However, based on what people share with me and what I continue to observe, there is still a great deal of confusion around the actual physics and biology involved.There are really three categories worth discussing. The first category is passive EMF devices. These devices have no power source. They claim to harvest ambient electromagnetic radiation and reorganize or modify those fields in a way that reduces biological stress. They often rely on geometry, fractal patterns, holograms, microchips embedded in pendants, or specific material combinations. The second category is active EMF signaling devices. These devices are powered systems that intentionally emit weak structured signals. They do not claim to overpower ambient EMF. Instead they claim to bias biological systems toward more coherent endogenous signaling and improved physiological resilience. The third category is what I would call active and dynamic signaling systems. Blushield falls into this category. It is active because it generates a field using an internal power source. It is dynamic because the signaling changes over time in a coherent way, more closely resembling the constantly shifting electromagnetic environment found in nature.To be clear, many of the concepts used to justify passive devices are not crazy or unscientific. Electromagnetic fields do have polarization. Geometry can influence how fields interact with materials. Fractal antennas exist in real engineering applications. Metals can couple to radiofrequency energy and act as grounds. Passive objects can scatter or redirect fields locally in the near field. All of that is true. This is why claims like an intentionally designed resonator can reorganize harmful EMFs and make them less biologically stressful sound persuasive on the surface.The issue is not the concepts themselves. The issue is scale, control, and guarantees.A passive resonator may produce higher local field intensity at specific frequencies by storing energy temporarily, much like a tuned antenna. However, this is concentration, not amplification in the engineering sense. Without an internal power source and maintained oscillation, a passive device cannot generate a dominant reference signal or enforce coherent structure across a room-scale environment.Without power, a device cannot control timing, phase, modulation, or coherence. It is entirely dependent on whatever ambient electromagnetic environment happens to be present at that moment, which is constantly changing. Geometry without power has no authority over signal behavior. Passive devices can respond to fields, but they cannot impose order on them.Over the years I have had many conversations with inventors working in active electromagnetic systems, including plasma based technologies. One important distinction that comes up repeatedly is that plasma can behave like a fractal antenna because it is an active medium with mobile charge carriers and energy input. That is fundamentally different from static geometry, etched holograms, or water/copper coil circuits which do not maintain oscillation, timing, or coherence on their own.Fractal antennas are real in engineering. However, they require specific parameters such as tuning to defined frequency ranges, feed points, impedance control, and known boundary conditions. A static hologram etched onto a pendant or card does not dynamically store electromagnetic information, adapt to changing environments, or enforce coherent signaling. It is a constraint, not a reference. Plasma systems can act like fractal antennas because they are active. They contain mobile charge carriers, dynamic oscillation, and energy input. That is a fundamentally different physical system than a static etched interference pattern. Calling both of these fractal antennas is a category error.One question that always stood out to me was how passive devices claim to cover large areas with no internal power source. Passive devices may slightly alter local coupling when worn on the body. That is plausible. What is not clear is how they could control room-scale fields or guarantee uniform effects across space. If a device truly created a dominant room-scale field, orientation, placement, and surrounding electromagnetic conditions would not matter. In reality, indoor EMF environments are dominated by near field sources such as laptops, phones, routers, and wiring. These signals reflect off walls and floors, creating standing waves and nulls. The result is a highly patchy and inconsistent field landscape. A small passive device only interacts with the local field where it is placed. It cannot average or reorganize an entire room. Its behavior will change depending on proximity to sources, wiring, and the body itself. That tells us the environment is in control, not the device.Passive devices have no internal timing reference, no phase authority, and no feedback mechanism. A passive microchip or circuit does not qualify as an internal reference because it does not actively maintain timing, state, or phase. Geometry and materials can constrain how a device responds to incoming signals, but they cannot enforce or stabilize a desired signal state. A reference requires actively maintained timing or coherence. Passive systems do not have that capability.Depolarization is another concept that has been widely misunderstood. Polarization refers to the orientation of the electric field. Coherence refers to phase stability and predictability over time. These are not the same thing. Modern radiofrequency environments are already spectrally complex, weakly polarized, and highly incoherent. Further depolarizing these fields simply adds randomness. It does not restore order. You cannot fix incoherence by adding more noise.In recent years many companies have used portable EEG devices to demonstrate before and after changes in brain activity. EEG can certainly reflect changes in mental state such as relaxation, attention, novelty, or expectation. It is extremely sensitive to posture, breathing, emotional framing, and context. What EEG cannot demonstrate is environmental EMF control, room-scale field effects, or mechanism of action. EEG does not measure cellular health, gene expression, calcium channel behavior, oxidative stress, or electromagnetic exposure levels. It tells you that a brain state changed, not why it changed. A device worn on the body could plausibly induce a local coupling effect. That does not mean the surrounding environment was altered. Small numerical changes can also appear dramatic depending on visualization choices and color scaling when creating before and after images.After evaluating many testing approaches, we chose to pursue the most rigorous path available to us. Rather than relying on internal or externally sourced white papers or theoretical models, we conducted an independent review board certified clinical trial in the United States. The results were published in a peer reviewed medical journal. We demonstrated significant changes in VGCC gene expression along with other physiological markers. This type of research is expensive and time consuming, but it aligns with the actual biological mechanisms being discussed.Biological systems are oscillatory, nonlinear, phase sensitive, timing dependent, and reference driven. This is why natural light cycles, geomagnetic fields, and environmental rhythms are so important to health. Biology does not simply respond to less stimulation. It responds to better organized information. The real question is not whether we can remove all EMF. It is whether we can provide a stable coherent reference that biology can lock onto.Active and dynamic signaling systems can do this. Passive systems cannot. Powered systems introduce a reference signal with internal timing and structure. That signal behaves consistently across environments. It improves signal to noise at the organism level. Passive systems have no phase authority, no internal timing, and no ability to resist environmental variability. They react to chaos, scatter chaos, and depend on chaos for their function. That is the opposite of what biology needs.Even mainstream EMF literature points to mechanisms such as VGCC activation, calcium influx, oxidative stress, and redox imbalance. An active coherent field can plausibly bias ion channel behavior, reduce stochastic noise, and support mitochondrial coupling. A passive scatterer cannot target these mechanisms or maintain biological reference states. Passive devices attempt to reorganize biology by harvesting incoherent ambient radiation. Active devices introduce order.We have been recommending Blushield for years as ones primary source of protection. Recently we introduced another technology that we found to pair perfectly with Blushield as the ultimate EMF protection stack.First, let’s look at the environment a bit closer.Modern EMF exposure isn’t just coming from wireless signals in the air. It also comes from the wiring inside our walls. Digital devices, switching power supplies, and LED drivers inject high-frequency transients and sharp voltage edges onto the 50/60 Hz electrical sine wave. That noise doesn’t just stay in the wires, it turns the wiring itself into a secondary source of electromagnetic variability.Blushield operates in the radiated domain by introducing a low-power, internally timed reference signal that remains stable even as the surrounding RF environment changes. It does not attempt to overpower external sources. Instead, it provides a consistent signal structure that biology can bias toward.SineTamer works at the electrical layer by reducing high-frequency transients and rapid voltage fluctuations on the building’s wiring. By lowering broadband electrical noise, it reduces the background variability that wiring can radiate into living spaces.Together, these two approaches address different layers of the same problem: one introduces structured reference signaling, the other reduces injected electrical noise. The result is not “shielding,” but a shift in signal organization and environmental stability.I genuinely want passive devices to be highly effective. I also want Nikola Tesla’s dream of a small portable device that produces clean energy from ambient energy to be real. But wanting something to be true does not make it physically possible yet. After ten years of experimentation, education, and direct testing, active and dynamic field signaling remains the most plausible approach I have seen for supporting biological resilience in modern electromagnetic environments.

Frequently asked questions

Invisible forces are part of modern life, but their impact doesn’t have to define you. Blushield works quietly in the background, supporting a more stable, balanced internal state so you can focus, rest, and perform at your best.

What does a Blushield device actually do?

It doesn't block or shield EMF. Instead, Blushield is designed to support the body's natural response to everyday electromagnetic exposure. By focusing on biological support rather than altering environmental signals, it takes a different approach to EMF protection.

Which device is right for me?

Plug-in units (Premium, Ultimate, Phi) cover your home. Portables cover you when you leave it. Most people start with one of each: a plug-in for the house and a portable for travel, work, and the car. If you're not sure, use our Find Your Device tool or message us.

What's your return and warranty policy?

30-day limited money-back guarantee on every device (restocking fee applies - see our full return policy). Stationary and portable units carry a 1-year warranty. If anything extends past that, contact us.

Do I still need it if I have low EMF readings at home?

Yes. EMF meters measure intensity, not biological impact. Even low-level exposure from Wi-Fi, Bluetooth, smart meters, cell towers, and nearby homes accumulates 24/7. Blushield works on the body's response, so it helps regardless of what a meter reads.

How long until I feel a difference?

Some people feel calmer or sleep better within the first night. For others it's a few weeks of gradual change - better focus, deeper sleep, and less fatigue. A small number notice a short adjustment period as the body recalibrates. Everyone responds differently, so give it time to become part of your daily environment and let the benefits build naturally.

Is there science behind this?

Yes. Blushield is built on decades of research into how the body responds to coherent vs. incoherent electromagnetic signals. We have independent studies, HRV data, and live-blood analyses on our Science page. We don't make medical claims. We point you to the data and let you decide.
