What is EMF and should you actually worry about it?
Issue 01. By Yarden and Jessica, co-founders of BioHarmonize.
Welcome to The BioHarmonize Blog. This is the first issue, and we wanted to start with the question we get more than any other.
What is EMF, and should you actually worry about it?
The honest answer is somewhere between "no" and "yes, a little." This post is here to help you understand what electromagnetic fields actually are, where they live in your home, what the science says today, and how a few small choices can lower your everyday exposure without changing your life.
We are not here to alarm you. We are here to help you feel grounded and clear-headed in the digital age.
A short answer up front
EMF stands for electromagnetic field. Every device that uses electricity produces one. Your phone, your wifi router, your laptop, your microwave, and the power lines outside your house all emit some form of EMF.
Most everyday exposures sit well below the limits set by the U.S. Federal Communications Commission (FCC) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP). At the same time, the World Health Organization's International Agency for Research on Cancer (IARC) classified radiofrequency electromagnetic fields as Group 2B, meaning "possibly carcinogenic to humans," in 2011. That classification has not been changed.
Both of those facts are true at the same time. The point of this post is not to push you in either direction. It is to give you a calm, real-world framework for thinking about a topic that is too often discussed in extremes.
What EMF actually is
There are two broad categories.
Non-ionizing radiation includes radio waves, microwaves, visible light, and the magnetic and electric fields around power lines and household wiring. This is the kind of EMF that comes from your phone, your wifi router, and your appliances.
Ionizing radiation includes X-rays, gamma rays, and ultraviolet light. This kind carries enough energy to break chemical bonds and damage DNA directly.
When people talk about EMF in the context of phones, routers, and homes, they are almost always talking about non-ionizing radiation. The science here is more nuanced than headlines suggest. Non-ionizing radiation does not break chemical bonds, but research is ongoing into whether long-term, low-level exposure has biological effects beyond the simple heating of tissue. The U.S. National Toxicology Program's 2018 studies on rats found "clear evidence" of certain tumors at high exposure levels, while public health agencies generally maintain that current limits are protective for typical human use.
Reasonable scientists disagree on what to do with that information. We think the most honest framing is this: the science is not settled, and small precautionary choices in the rooms where you spend the most time are worth making.
Where EMF lives in a typical home
If you walk through a modern home with an EMF meter, the highest readings tend to come from a few predictable places. We use the Trifield TF2, which measures magnetic, electric, and radio frequency fields in one device, but any reputable meter will surface the same patterns.
Your wifi router. Most home routers broadcast continuously at 2.4 GHz and 5 GHz. The closer you sit, the higher your radio frequency exposure.
Your phone, especially when streaming, uploading, or in low-signal areas. A phone working hard to find a tower transmits at higher power than a phone with full bars.
Smart meters on the outside of the house, which transmit usage data to the utility company in regular bursts.
Bluetooth devices, including wireless headphones, earbuds, smartwatches, and speakers.
Power strips and chargers, which create localized electric fields, especially when bundled under a desk or behind a nightstand.
Microwave ovens, which leak small amounts of radiation through the door seal even when working as designed.
None of these are individually alarming. The conversation worth having is about cumulative exposure, especially in the two rooms where most people spend the most uninterrupted hours: the bedroom and the workspace.
The story behind BioHarmonize
I am Yarden. My wife Jessica and I co-founded BioHarmonize after I developed persistent tinnitus that no doctor could explain. I tried everything. Sleep changes. Diet. Supplements. Therapy. Nothing moved the needle for long.
A friend mentioned EMF as a long shot. I bought a meter to humor him. The first time I started taking readings around my home, the numbers were higher than I expected. The strongest signals were not the ones inside the house. They were coming from the smart meter mounted on our exterior wall and from the power lines running close to the property. Those two sources, more than anything else, are what I now believe were driving the exposure I had been living with.
I started making changes. I added shielding where I could. I moved devices and chargers around. I rethought the bedroom and the spaces where I spent the most uninterrupted hours. I made a habit of putting my phone in another room at night. The shift was not fast. Over the next few years, the tinnitus gradually quieted. It has not disappeared. I still live with it to some degree, but it is significantly better than it was.
I cannot prove EMF was the cause. I can tell you what changed. This is an ongoing journey, not a finished story.
Jessica came to this through her own door. Before we got married, she lived on her own in a small apartment. Her wifi router sat under her nightstand, a few feet from her head. As she puts it:
"I never thought about it. It was just where the cable came in. When Yarden showed me the readings in that room, I moved the router into the living room the same day. Within a couple of weeks I was sleeping more deeply. I had no idea I was sleeping that lightly until I wasn't anymore."
Her experience was different from mine, but it pointed in the same direction. The spaces where we sleep matter.
That shared conviction kicked off four years of research and seven prototypes. BioHarmonize was born out of the belief that you should not have to choose between modern life and feeling grounded in your own body. We are family-owned, mission-driven, and based in Santa Monica.
A simple framework for thinking about exposure
You do not need to become an EMF expert. You only need to remember three principles.
Distance matters most. Radio frequency exposure drops sharply as you move away from a source. Doubling your distance from a router or phone cuts your exposure by roughly a factor of four. Moving your router three feet farther from your desk does more than any product on the market.
Time matters next. The longer you spend near a source, the higher your cumulative exposure. The bedroom and the desk are the two highest-leverage rooms in any home, because that is where most people spend the most uninterrupted hours.
Source strength matters last. Some devices emit more than others. A wifi router on the kitchen counter is a stronger signal than a smart thermostat down the hall. A phone uploading a video is a stronger signal than a phone sitting idle.
Distance, time, and source strength. That is the whole framework. Everything else is detail.
What to do this week
If you want to take one small, intentional step before next week's issue, this is the one we recommend.
Move your wifi router. Find a location that is at least six feet from where you sit at your desk, and at least ten feet from your bed. If your router currently lives in your bedroom, consider moving it out of the room entirely. Use a longer ethernet cable if needed. This single change tends to produce the biggest measurable difference for most households.

What is coming next
The BioHarmonize Blog is a place for the slower, longer conversation about modern life and the human body. Future issues will cover:
The bedroom audit. How to set up your sleep environment to support deeper rest in a wifi-saturated world.
Phones and pockets. What current research says about long-term phone proximity, and the small habits that lower exposure without giving up your phone.
Children and EMF. What we know, what we do not know, and the precautionary choices many families are making.
Real-world product reviews. Honest assessments of meters, shielding products, and tools we use ourselves, including ours.
We are a small, family-owned company. We will tell you when we do not know something. We will keep showing up here, and the goal is always the same: to help you optimize your environment and unlock your potential.
Thank you for being here.

Frequently asked questions
Is EMF radiation the same as nuclear radiation?
No. EMF from phones, routers, and appliances is non-ionizing, meaning it does not carry enough energy to break chemical bonds or damage DNA directly. Nuclear radiation is ionizing and operates by a different mechanism.
Has the World Health Organization classified EMF as carcinogenic?
The IARC, which is part of the WHO, classified radiofrequency electromagnetic fields as Group 2B in 2011, meaning "possibly carcinogenic to humans." That category also includes substances like aloe vera extract and pickled vegetables, so the classification reflects uncertainty rather than confirmed harm.
What is the safest distance to keep from a wifi router?
There is no single official "safe distance," but radio frequency exposure drops sharply with distance. A common precautionary recommendation is at least six feet from where you sit and at least ten feet from where you sleep.
What EMF meter do you recommend for beginners?
We use the Trifield TF2 because it measures magnetic, electric, and radio frequency fields in one device. It is widely considered a reliable starting meter for households.
Does BioHarmonize sell EMF protection products?
Yes. We make EMF Protection Harmonizer Stickers, an EMF Shield Privacy Phone Sleeve, and a Complete System bundle. Our products are designed to complement, not replace, the distance-and-time principles described above.
