Science-backed reasons to question the safety of digital fitness trackers like the Fitbit and how to protect yourself if you choose to use one.
A Fitbit is a type of electronic device used for personal activity tracking. These wireless-enabled, wearable devices measure data such as the number of steps walked, quality of sleep, and other personal metrics.
The Fitbit was developed by the company of the same name founded and managed by James Park and Eric Friedman.
Since then, a proliferation of various styles and models have taken the workout world by storm. There are now similar knock-off devices crafted for every personality and need.
The very simple Fitbit Zip, which is about the size of a quarter, tracks only steps taken, distance traveled, and calories burned. The sophisticated Fitbit Flex, which is worn 24 hours a day even while showering and swimming, tracks all its wearer’s movement including sleep patterns.
There are Fitbit apps for the iPhone and Android too which allow fans to log their food, activities, water intake, and weight, as well as track their fitness goals throughout the day even while offline.
While these types of devices may seem like a very helpful tool to keep people motivated and moving toward exercise goals, I don’t personally use one. I also don’t recommend them to people who ask me about them (by the way, a fascia blaster isn’t healthy either).
Here are my science-backed reasons.
Exercise is About Relaxation, Movement and Stress Reduction
For me, exercise is primarily about movement, relaxation, and stress reduction. It frees the mind from the cares of the day for a short period of time.
Adding a lot of data and personal activity tracking to the mix is decidedly un-relaxing to me. I don’t want my every breath, step and heartbeat chronicled, tracked, and categorized as I go through my workout whether it be a leisurely stroll around the neighborhood or a high-intensity rebounding session on our outdoor trampoline.
Tracking my steps around the house as I do laundry, cook, and wash dishes seems very over the top and rather invasive too. Can’t we just enjoy our exercise and daily activities without having to micromanage and examine every aspect under a microscope?
This takes much of the joy, relaxation and ultimately, health benefits out of it, in my opinion!
Exercise is not primarily about weight loss either at least to me. It’s about getting the blood pumping to facilitate the body’s detoxification mechanisms and to build and maintain muscle, fitness, and balance. Simple burning of calories may help you lose weight but this alone never got anyone healthy, so why bother tracking exercise at such an elementary, two-dimensional level?
While some may find Fitbits helpful to the exercise process, to me, they detract from the psychological benefits of exercise enjoyment by micromanaging what should be experienced in an expansive manner.
Fitbit: Unnecessary Exposure to EMF Radiation
There are pictures available that show actual wireless radiation surrounding a person using a wireless-enabled device. You can see photographer Luis Hernan’s incredible photos here.
While it is basically impossible to get away from the constant bathing of the body in wireless radiation while at work or in a public place, exercise particularly in the outdoors offers a prime opportunity for rest and release from the onslaught of electromagnetic fields (EMF) for a brief period of time.
It makes no sense, at least to me, to be hooked up to a device like a Fitbit that emits any sort of EMF radiation while exercising which is already putting the body under physical stress from sweating and detoxification.
A Fitbit that people wear while sleeping seems most dangerous of all. There is absolutely no data proving the safety of these devices during sleep even though the user manuals claim that “This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.”
Quality sleep is very important for maintaining a healthy weight. Research has shown that poor quality sleep causes weight problems. Even just a few nights of poor sleep can lead to almost immediate weight gain. (1)
Are Fitbit night wearers undoing daytime weight loss efforts?
In fact, sleep and good health are so inextricably linked that many holistic medical practitioners recommend turning all wireless sources off at night with some going so far as to recommend flipping the entire house breaker until morning! The reason? The EMF radiation swirling around you may negatively affect sleep in a very profound way over the long term.
I’ve written before about how wireless baby monitors aren’t a good idea for sleeping babies. Fitbits worn during sleep transmitting data via wireless are a bad idea for similar reasons.
According to PowerWatch, a wireless baby monitor at less than 1 meter away from the baby’s crib was roughly equivalent to cell tower radiation standing only 150 meters (about one-tenth of a mile) away. (2)
How much worse would a wireless-enabled Fitbit be that is worn on your physical person as you exercise or sleep?
Metal in Your Mouth Can Make the Problem Worse
Interestingly, if you have dental amalgams (silver fillings) or titanium implants, this may make the wireless radiation from constantly wearing a digital fitness device even more problematic. According to Lina Garcia, DDS, DMD:
When considering the numerous reasons for the increasing prevalence of chronic illness in our society, I think that we should not overlook the possibility that metal-containing dental work, especially titanium implants, could be acting like antennas for the microwave [which includes wireless] transmissions going on between our cell phones and all of the cell phone towers in our 21st century environment.
… it is important to be aware that metal dental restorations and implants have already been shown to cause galvanic and electromagnetic stress for the human body. Galvanic and electromagnetic stress occurs when an unnatural electric current is generated by metal ions interacting with the electrolyte-rich fluid known as saliva. (3)
If you doubt that you are surrounded by very strong wireless radiation while wearing a wireless-enabled device be it a cell phone or a Fitbit, you can now download an app that will give you a colorful visual on those waves invisibly surrounding you with blue indicating the strongest wireless radiation down to red which indicates the weakest signal.
Heavy Metal Exposure?
In March 2014, the Consumer Product Safety Commission officially recalled the Fitbit Force due to injuries to an estimated 9,900 people. These customers suffered from skin irritations such as blisters, rashes, and peeling skin after the continual wearing of the Fitbit Force for a period of time. Fitbit stated that after consulting with medical professionals, the general assessment is that the skin problems were likely allergic reactions to nickel, an alloy in the stainless steel or adhesives used to assemble the Fitbit Force.
While it is well known that ingesting heavy metals like nickel can cause health problems, what is less well known is that the skin can absorb heavy metals too. (4, 5)
Cooking acidic foods in stainless steel is known to leech alloys like nickel into the food, but could stainless steel placed on the skin which is normally acidic at a pH of 4.5-5.5 leech metals too? Even minute amounts of heavy metals in the body can have negative health consequences so this is far from a trivial concern. (6)
Until there are more research and definitive answers to this question, it seems prudent to be wary of products like the Fitbit Force that expose the skin to heavy metals for extended periods of time.
Must Have a Fitbit?
If you find that despite any health concerns, you simply must have a digital fitness device to track personal activities, my suggestion would be to seek one of the older models that work mechanically rather than digitally.
For example, a basic mechanical pedometer counts steps by measuring how much the body shakes. An internal object moves up and down with the motion of the person wearing the pedometer, which senses the vibrations of feet hitting the floor. As the ball moves, it activates a switch that clicks the counter forward.
You can tell that you have a mechanical pedometer as it will work simply by shaking it even without any walking involved.
My Experience Using a Fitbit Scale
While I don’t wear a Fitbit like device for the reasons cited above, I did use a Fitbit scale once a few months back. These devices measure BMI, body fat and other health statistics by sending an electrical signal through the body.
While the companies making these scales insist the signal shot through the body to gather the data is safe, the scale isn’t recommended for pregnant women, children under 10, or anyone with an implanted medical device.
While I do not consider myself EMF sensitive in any way, I felt immediately light-headed and fatigued after having my health statistics gathered by the Fitbit scale. The experience really surprised me, as I didn’t expect a single-use to produce such a reaction. I didn’t feel right until a number of hours later.
Needless to say, I won’t be using a Fitbit type of scale again in the future!
Electronic Weight Loss Device Use is a Personal Decision
While choosing to use products like the Fitbit ultimately is a personal decision like whether or not to put a cellphone up to your head, in my book, it seems important to learn to switch off from our constant exposure to electronic devices and EMF radiation.
Exercise and sleep are the most obvious times to give yourself both a mental and physical break from EMF exposure.

How to Protect Yourself from a Smart Meter
I received the Fitbit as a gift last October. I didn’t connect the things happening. Went to the emergency room for chest pains in late October. The EKG was abnormal. I’ve never had that before. Sleep hadn’t been the best but I just attributed that to my lifestyle. This year around February I started feeling palpitations. I see my doctors on a regular basis due to undiagnosed sleep apnea. Fast forward to my echocardiogram in July, I wasn’t good and showed some things were worse. I was then scheduled for a trans-echocardiogram. Two weeks before, I was looking at my wrist and noticed the break out on my wrist and I decided to take off the FitBit. I had my trans-echocardiogram and the doctor, during the test told me that my condition is mild and did not require anything to be done. I think GOD had been speaking to me about this FitBit but I wasn’t listening until I saw the rash.
I’m never putting that thing back on. I feel so much better!
To top it off, I do have braces.
Total BS article, there are countless studies on the safety of WiFi, you just ignore those…

Mmmmm. And, WHO, might you think, paid for those psy-op articles? Wake up.
If we really want to keep it simple – use a manual odometer (powered by a battery) and keep moving until you reach 10,000 steps. I don’t recall why 10,000 steps is the desired goal yet that is the figure I’ve seen in articles. Even if it’s not accurate to the nth degree – it’s one less radiation source to contend with.
you can downlload any health related apps in Apkness
Wow. This is ignorance and wokeness combined in one… seriously. You are obviously writing for pretentious people who don’t train for any other reason than social constraints… as opposed to the person on the street, who perhaps midlife decides they need to do better and wants a device to help them along. I bought one last night, it’s my first day with it, and I was motivated to get up and walk 5km before breakfast because I could then access data. It’s good to see BP, heart rate, steps, joules, etc etc. it shows me my sleep hours. The EMF does exist, but making one phone call on a mobile is worth a year or wearing a Fitbit (look it up). Unfortunately it’s an emf world. For the person that needs it, perfect. For the poseur… it’s disposable, and for yourself it’s something else to complain about and ban because you don’t like it…
Nope I dont. As I read first part I thought get the pedometer that shakes. I still have mine from 20 years ago if I want to track step. I tried app on phone a while ago. Turn on only when i walked. All those water reminders and such were well…. it didnt work well anyway. Just use pedometer if I want to track. Sending to others to awaken them.
The Whoop (wrist band) that monitors heart rate variability has really been taking off. Sara, would love your thoughts on that vs the Fit bit. Fascinating company taking the sporting world by storm. It’s Bluetooth (I believe) but no idea what they say in terms if it being any less risky/EMF harmful than others. Would love your/anyone’s thoughts.
Sarah Pope MGA
Bluetooth is a no-no from an EMF safety perspective.
I bought an Apple Watch for heart, sleep and steps data. I developed a lump on my wrist and was worried so I stopped wearing the watch for over a month or more and the lump finally disappeared. To be sure I started wearing my watch again, within a month my lump came back and kept getting bigger. I took off my watch for good and it took even longer for my lump to shrink again. Don’t guess I will be able to ever wear one again.
I always thought Fitbit is good to track our health. Never thought it would have such negative effects too. Thank you for guiding us with your research. You are doing great work. Hoping to get more knowledge from you about health measures.
This is VERY interesting. For about a year and a half I have gained weight that I can NOT get off and I still eat my normal (pretty healthy) diet. But here’s the biggy. While sleeping at night I will have INTERNAL vibrations so strong they will wake me. And other nights not so strong but still aware of them. I told multiple doctors as it scared me at first. I thought I was rolling over maybe on something pressing a nerve. BTW, I wear my FITBIT to bed and have for about this same period. OMGosh.. I hope this is the reason as it will be an easy fix. I woke last night with MAJOR vibrations and was AWARE of my FITBIT which I never felt. So I took it off. Do you think this could cause vibration sensations inside the body. You can’t feel or see them outside of my body. Please tell me yes and the FITBIT will be history. Btw never in the daytime that I’m aware of this feeling so could be when I lay on it in a certain way at night. I was going to make an appointment with a neurologist!!!
Sarah Pope MGA
EMF symptoms vary widely among those that are sensitive. I know for me, I wouldn’t sleep a wink wearing a fitbit. I am quite sensitive … we have to turn off the wifi in our home too else I find it disruptive. Hopefully, removing the fitbit will help resolve these problems for you.
Hi. Would you say it’s still unhealthy even if you turn off the Bluetooth/wireless on the Fitbit? Thank you!
Sarah Pope MGA
That would be much better of course! The safest is a mechanical/analog fitness tracker.
Very interesting – Recently I purchased a fitbit versa (still in its’ box); a friend suggested for me; possibly to encourage me to start walking again. Now I really do not know what to do. I am healthy, just thought it would be fun-not unhealthy.
Sarah Pope MGA
My suggestion would be to get a mechanical pedometer.
