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.
Mmmmm.
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.
Do you use a Fitbit? What are your reasons for doing so and do the potential health risks concern you?

I first bought my fitbit in December 2015. I immediately started wearing it all day, everyday, except to shower. In January 2016 i was laying in bed and started having severe pains on my left side right under my breast and where the heart is located. It felt like someone was stabbing me in the heart over and over. I couldn’t breathe the pain was so bad. My fiance rushed me to the hospital. They did a C.T scan, gave me some pain meds, and blood tests. The results of CT scan showed I had ONE gallstone. Blood test game back with some missing markers, whatever that means. But Dr. Said it was because I did have a gallstone. The next day I had an ultrasound of my abdomen and confirmed one gallstone. I went to the surgeon. After talking with him and him looking at the ultrasound he told me that gallstones pain is located on the right or middle part of the chest. And my symptoms were not matching up. He told me he was only 50% sure the pain I experienced was from the gallstone. We elected to wait on surgery. Since that time in January I have experienced some pain from the gallstones. Which is now identifiable to me and it is not the same pain i experienced that night. I have not worn my fitbit since because I associated with wearing my fitbit to that night of excruciating pain. I am writing this because I finally put my fitbit on, wore it for 3 days, all day long, and started feeling my heart feeling weird. Tonight I felt 2 sharp pains in my left chest area, which feels like my heart. I immediately took my fitbit off. I need and want to know if this fitbit is dangerous to my health
I have worn fitbits for years slept more and better than ever lost weight and reduced body fat putting me in the best shape i have ever been. I am 43 years old and been a mental health professional for over 20 years. Sure Sarah is well entitled to her opinion. One thing I would say is that human confirmation bias enables us to find evidence and information to support what we want it to. I accept that i am not immune to this. That said I also know that my health and fitness improvements are real and I “feel” my use of fitbits as assisted not hindered. I also consult a personal trainer, do self research and use my own common sense.
Hi Sarah, you mentioned that “Any device that is strapped to your body and uses wifi or cellular radiation to track biological activity is problematic to health over time.”
Do you have any reputable sources (preferably peer-reviewed) that genuinely support this claim? So many people will claim EMF radiation is dangerous, but will fail to distinguish between ionizing radiation (e.g. Gamma, X-ray, Ultraviolet) and non-ionizing (visible light, microwave, WiFi, radio, etc). To my knowledge, I have not found any reputable sources that can prove that non-ionizing radiation is carcinogenic or unhealthy, other than just the potential heating effects (which are almost negligible in devices like these).
If it were the case that non-ionizing radiation is unhealthy, then we might as well be living in dungeons because visible light is a non-ionizing radiation as well, just like WiFi or anything else below UV rays on the EMF spectrum.
Here’s an article on the CDC take on the issue articles.mercola.com/sites/articles/archive/2016/01/20/emf-controversy-exposed.aspx
I have been concerned about my fitbit. I’ve had it for approx 3 months and my body has been feeling really ache all over and not sleeping well. So I asked my husband if it could be the fitbit. I have worn it non stop for about 3 months except to shower. My body just doesn’t feel right. To me its like having a little computer attached to me 24 hours a day. I’m pretty sensitive to things too. I really like my fit bit…but I’m going to not wear it for awhile and see if things get better.
This is a rather terrible article. It’s full of conjecture and speculation. The reader who does not read closely at the ridiculous claims being made will be led to believe that there must be something harmful going on – when there is virtually no stated facts or evidence of these many allegation by the author. As articles go, this is highly misleading and borders on outright dishonesty. Be careful what you read online people – ‘advice’ is often dangerously unqualified and non-researched.
For me the fit bit is more like a tool that helps me keep good habits in the back of my mind. I don’t feel dedicated to court steps or calories. I walk a lot to begin with and am fairly active. It is more of a gentle reminder for me to pay attention rather than I must do this or that. I could quickly see in many ways it was not accurate. I believe how you use it is very important. Use it as a tool and very general guide, not a begin and end all.
I work in a naturopathic clinic and the doctor I work for has noticed a direct correlation between Fitbit use and the development of cardio problems where they were not present before starting to use Fitbit.
I use shielded clothing and for those who is suffering I can confirm that it really makes a difference! But make sure your protective garment has decent shielding level and it has a graph showing dB and GHz values like all products here emfclothing.com
30k steps is excessive. I don’t believe the problem is with the Fitbit, but more with the addiction to getting steps you formed on your own.
Just because you are unaware of the harmful energies swirling around you does not mean they do not exist. Many of us can feel it. Are you claiming mercury fillings are safe? Or that x-rays are not damaging? And what about the toxic fluoride? It is a wonder any dentist lives beyon age 50.
