In a 12-week, independent review board (IRB) certified, PubMed-indexed clinical pilot study of 25 relatively healthy adults, Blushield devices were found to be feasible, safe, and associated with statistically significant improvements in cognitive function, deep sleep, heart rate variability, blood glucose, immune markers, voltage-gated ion channel gene expression, and overall self-reported health. No adverse events were reported, and 100% of participants complied with device usage. Here's the full story of how the study came together and what it found.
How the Study Began
Back in September of 2020, we were contacted by Tom Blue, the owner of a research company and Executive Director of the American Academy of Private Physicians. Tom is connected with a large network of doctors. He had recently discovered Blushield EMF protection devices and noticed significant positive results from using them on himself, his wife, and their son. All three regularly track various health markers using the Oura Ring device, and the improvements they saw in sleep quality and heart rate variability were impressive enough to inspire Tom to reach out to us.
Tom proposed studying the health effects of our devices on humans, on a larger scale than we had attempted previously. Tom and his partners, Helen Messier, MD, PhD, and DeAunne Denmark, MD, PhD, had great ideas about the structure and focus of the study, a variety of health markers to track, and how to recruit participants within their network of doctors. They also had connections with independent labs that could perform the study for us.
Many months were spent ironing out seemingly infinite details, signing contracts, recruiting participants, and navigating the biggest worldwide slowdown of many of our lifetimes - the Covid lockdowns - which kept pushing back our ideal timeline. Finally, in March of 2022, test kits were made and sent to all participants, along with a Premium Ultra home device for each participant, plus a Plugin and/or Premium Portable for those who worked away from home or traveled often, to ensure they were within the Blushield field as often as possible during the 12-week study.
Study Design and Participants
The focus of this pilot study was to assess the feasibility and preliminary signs of efficacy of our devices on a small sample group within a fairly short time frame, to determine whether a full-scale research project would be worth planning in the future.
All 25 participants worked in the health and wellness industry, including general practitioners and physical therapists, and all self-reported being in relatively good health at the start. This was a single-arm study - in this case, a "before and after" study - in which all participants were tested before using Blushield, then again during and after 12 weeks within the influence of the Blushield device.
100% of participants reported compliance with device usage for the study duration, meaning they remained within the Blushield field. This increases both the validity of the results and the feasibility (ease and practicality) of using the devices, even for the busy professionals in our sample. No adverse events were reported during the 12 weeks.
A variety of health markers were tested using several methods, including:
- Laboratory panels assessing overall physiological health
- A panel of blood markers related to inflammation, oxidative stress, DNA damage, and cellular senescence
- A genome-wide assessment of DNA methylation (including the voltage-gated calcium channel sites)
- A full neurocognitive assessment every 4 weeks of the study
- A wearable health tracker (the Oura Ring) to analyze changes in sleep quality, heart rate variability, and related markers
- Self-reported health questionnaires
Analyzing and Interpreting the Results
Our study paper was written by Christopher D'Adamo, PhD, an epidemiologist who has served as Principal Investigator on a wide variety of observational and interventional studies of nutrition and other healthy lifestyle modalities. His findings have been published in several well-known peer-reviewed scientific and medical journals and publicized through several popular media outlets.
The study co-authors include the researchers involved in compiling and interpreting the data: researchers from TruDiagnostic (the epigenetic data analysis company that provided the genome-wide DNA methylation assessment); doctors Helen Messier and DeAunne Denmark, who organized the study; and Tom Blue, who got the ball rolling initially.
In the study paper, it is stated:
"Preliminary data from in vitro and agricultural animal studies suggest changes in biomarkers of health and functional status may be detectable after a period of continuous BluShield device usage."
This refers to our prior Blushield studies from several years ago - the grassroots-style testing where we initially found impressive positive results in animals and humans, including live blood cell analysis, human urine analysis, and health improvements in chickens and cows.
We knew it was time for a more thorough study on a greater number of human health markers, using a newer, more powerful Blushield device - and we're thrilled the study is now complete. So, what improvements were found in this IRB-certified pilot study?
Cognitive Function Improvements
The CNS Vital Signs test is a full neurocognitive assessment that each participant completed once before introducing the Blushield device, then again every 4 weeks of the 12-week study, for a total of 4 times. The test records performance across areas of cognitive function, including memory, executive function, and processing speed.
Statistically significant positive results were found in composite memory, cognitive flexibility, executive function, and processing speed. There were several areas where no changes were noted (visual memory and simple and complex attention), but the areas of positive change are quite notable.
Electromagnetic field exposure has been definitively linked to impairments in cognitive function, with the mechanism of harm theorized as overactivation of the voltage-gated calcium channels, as described in our previous article: Memory, Learning & Attention Impairment From EMF Exposure.

Voltage-Gated Calcium Channel Improvements
Could our positive cognitive results be linked to the voltage-gated calcium channels (VGCCs)? The study paper states this is a valid hypothesis that warrants further exploration. The reason a link is suspected: in the genome-wide DNA methylation assessment, researchers identified a key VGCC gene (CACNA1G) that was hypermethylated, indicating a likely under-expression of that gene - essentially a quieting of the voltage-gated calcium channels that are chronically overactive and overstimulated in the constant presence of modern EMF levels. Hypermethylation is most often associated with downregulation of a gene's expression, placing it in a "locked" state, whereas hypomethylation usually refers to active expression and transcription.
204 total CpG sites were found to be differentially methylated between the before and after measurements, and 94% of those genes were hypermethylated. A considerable number of these sites were connected with the ATP-sensitive potassium channels, which are known to be influenced by EMFs. Besides the one key VGCC gene that was hypermethylated at a level of statistical significance, 4 other VGCC-related genes were very near the threshold of significance.
CpG is short for Cytosine-phosphate-Guanine, the most common methylation pathway in DNA. DNA methylation is an incredibly important epigenetic health marker. Epigenetics is the study of genes activating or silencing (commonly through methylation) in response to changing environmental factors, and it can explain why family members - even identical twins - with nearly or exactly the same genome can experience widely different health outcomes. It calls upon the "nature versus nurture" question, where "nature" is the static state of the genome you were born with, and "nurture" refers to the outside influences you encounter throughout life that actually switch genes on and off, dynamically altering the trajectory of your health.
Another fascinating purpose of DNA methylation is to silence intragenomic parasites. It's hard to believe, but at least 35% of our genome is made up of parasite DNA. These parasites are called transposons, and include endogenous retroviruses that have inserted themselves into human DNA over a very long period, long before our lifetimes. When functioning optimally, DNA methylation should keep this parasitic DNA quiet and dormant for our entire lives. When environmental influences such as toxic heavy metals and electromagnetic fields disrupt our bodies' ability to methylate properly, dormant retroviruses can become active, often wreaking havoc throughout the body.
Meaningful Improvements in Sleep Quality and Heart Rate Variability
All participants wore an Oura Ring throughout the entire study, from the pre-Blushield "before" period through the 12 weeks of use. This wearable continuously records a variety of relevant health markers, making it easy to track the effects of lifestyle changes in real time.
The device tracks the full sleep cycle and provides detailed data on minutes of deep sleep, REM sleep, light sleep, and awake time. It also records heart rate variability (HRV) on an ongoing basis - a key marker of vitality, resilience, and adaptability. "Variability" refers to the heart's ability to respond immediately to environmental demands by speeding up or slowing down as needed; the body's ease in changing heart speed instantaneously is strongly linked to overall health and vitality. You can learn more in our article: Heart Rate Variability (HRV) as an Advanced Biomarker is Affected by EMFs.
Our participants saw impressive improvements in heart rate variability, average and lowest resting heart rate, body temperature, and deep sleep - all reaching statistical significance. Average deep sleep time increased by 9 minutes, from 90 minutes before to 99 minutes after. There was also an increase in average awake time (by 5 minutes), which in some cases wouldn't be desirable - but it's a logical assumption that if you're getting 9 extra minutes of deep sleep (the most restorative type) per night, you may not need quite as much sleep overall.
Reduction in Blood Glucose
EMF exposure has been shown to be linked to elevated blood glucose, and in some cases even prediabetes and diabetes. This is thought to be related to the voltage-gated calcium channels, as our previous article elaborates: Blood Glucose & Insulin Negatively Affected By EMFs.
All participants had glucose levels within a healthy range at the start, and we still found a statistically significant reduction in blood glucose during the study. The results may have been even more dramatic if diabetics and prediabetics had been included - a topic of particular interest for a potential future study.
Glucose and insulin are also strongly affected by the ATP-sensitive potassium channels, so it's possible the positive effects on blood glucose are linked to the hypermethylated ATP-sensitive potassium channel complex our study recorded, as well as the VGCCs.
Changes in Immune Markers & Self-Reported Health Improvements
The study also found an increase in monocytes and a decrease in natural killer (NK) cells, both within a healthy range. Monocytes remain in their basic form in the bloodstream and organs when there are no active threats, but as soon as a threat is perceived, they differentiate into either macrophages or dendritic cells. NK cells, however, remain in their original form while fighting infection. When monocytes differentiate into dendritic cells, this alerts other cells (including NK cells) to the presence of an imminent threat.
There is a hypothesis that electromagnetic field exposure triggers the immune system, as our bodies perceive the foreign frequency patterns as invaders to attack and defeat. Since there is nothing physically present to attack and destroy, this can result in a chronically elevated immune response, which eventually depletes the immune system's power and steals vital resources from other essential processes. Our long-held theory, based on previous studies, is that being within the influence of a Blushield gives the body a healthy field to preferentially resonate with, calming and subduing the futile immune response against the perceived invasion of harmful fields.
An increase in circulating monocytes could indicate they are now "ready and waiting" in their natural form, rather than actively fighting infection by differentiating into other forms. A decrease in NK cells could signify the immune system calming down from a previously chronically overactive state, as the monocytes are not actively signaling a threat that would tell the NK cells to get to work. More targeted and larger-scale studies will be needed to confirm this hypothesis.
Each participant also completed a self-reported health questionnaire at various times throughout the study, and there was a statistically significant improvement in participants' subjective experience of overall health and well-being.
Understanding P-Values and Confounding Factors
To fully understand the study paper, it helps to understand p-values, the calculations used in clinical studies to determine whether a result is statistically significant or more likely random and insignificant.
P-value stands for probability value and is directly connected to a concept called the "null hypothesis." This refers to the potential - present in every scientific study - that the intervention being studied (the device, drug, or other influence) is having no positive or negative effect, and therefore the results are due to random chance. To achieve statistically significant positive results, you want the p-value as low as possible. The lower the value, the less likely the results are due to chance; if it's low enough, it's almost certain the intervention is truly affecting the subject. Even when the value is extremely low, there's always a tiny possibility it's due to chance, which is why the number can never reach zero.
Depending on the parameter being studied, the significance threshold is set at a certain number. P<0.05 is a common one, which most of our study parameters used. 0.05 means 5%, so P<0.05 means "the probability that this result is due to random chance is less than 5%." Any result below that threshold is considered statistically significant.
So a study result with a p-value of p=0.01 means there's only a 1% chance the result was random and a 99% chance the intervention (in our case, the Blushield device) directly affected the result - as we saw with resting heart rate. Some of our other results had even lower p-values, like p=0.0007 (our cognitive flexibility result), meaning only a tiny fraction of a percent chance of being random.
Later in the paper, there is a discussion of confounding factors - uncontrollable factors in the study design that may have influenced results, which are essential to consider in any study lacking a control group. Some confounding factors are external influences from daily life; in this case, they may include changes in physical activity or diet due to changes in season. Another factor is a lack of diversity in the health status, education level, and race of the subjects. All subjects self-reported as relatively healthy; if more chronic-illness sufferers had been studied, there may have been even more room for improvement from baseline.
Accuracy Score of Our Methylation Results Was Very Close to Perfect
Observing changes at the DNA level is a very complex process, as you can imagine. Those performing the measurements must have specific, extensive training, and they must create a model that factors in all the variables (age, sex, immune markers, and an infinite number of other potential variables) so the result is as accurate as possible. The theoretical goal is a model that shows pure cause and effect, where variables applicable to this particular study group (called covariates) are factored in as a "perfect fit." Pure cause and effect, in our case, would be results measuring exactly how Blushield use affected methylation of the CpG sites, with the model already adjusted to erase the impact of covariates.
There are ways to assess the accuracy of the model, although a perfect fit is impossible. The perfect score is a "1" - anything less than 1 means there are too many covariates and the results aren't as significant as they would be in a pure model; a number higher than 1 means there aren't enough covariates and the results are more significant than they should have been. Our study's model was mapped on a Q-Q plot, which gave a score of 1.05. This score is almost perfect, and we were told it isn't easy to achieve. This means the methylation results we saw on the CpG sites, including the voltage-gated calcium channel genes, were almost as pure and accurate as they possibly could have been.

Final Thoughts
This study was a long time in the making, involving extraordinary levels of hard work and patience. Almost daily here at Blushield, we hear reports directly from customers - and in the reviews they post voluntarily on our website - that these devices have affected their lives in positive ways, with some calling them life-changing. Honest customer reports help inform new potential customers of what others have experienced, clarifying their decision to invest in our EMF protection devices.
Now, with our first IRB-certified clinical study results under our belt, customers can be even more fully informed of the potential benefits this technology may have on their lives. Although it was a fairly small-scale pilot study, in some ways it is genuinely groundbreaking: we are the first EMF protection company we're aware of to test the effects of our devices on the voltage-gated calcium channel genes and find notable improvements. This is something we will certainly test more extensively in future, larger-scale studies.
The study paper concludes that Blushield devices appear to be feasible, safe, and associated with improvements in cognitive function, sleep, heart rate variability, voltage-gated ion channel gene normalization, blood glucose, immune response, and overall self-reported health among relatively healthy adults. It also emphasizes that the devices "appear to be a reasonable component of a comprehensive EMF mitigation strategy to minimize RF exposure" - which is always how we encourage people to use our devices.
You're welcome to share this with anyone in your life who is concerned about the harmful effects of EMFs and is looking for sound, research-backed solutions.

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.

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.
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.
Yes. Blushield is built on decades of research into how the body responds to coherent vs. incoherent electromagnetic signals.
