Does A Fitbit Emit EMF Radiation?

Many wearable fitness trackers claim that they don’t expose users to any harmful electromagnetic radiation (EMR).

However, a lot of studies have shown that the majority of smart wearables, including fitness trackers, emit electromagnetism. The World Health Organization (WHO) did its own study and found that wearable technology devices – including Fitbits – emit EMR that exceeds recommended levels.

The reason for this may be the lithium-polymer batteries included in most wearable fitness trackers. A study presented at the 2015 Annual International Conference of the IEEE suggests that some watches emit energy in waves that oscillate between 2.5 MHz and 20 MHz. These waves are in the microwave frequency range, which could be harmful when emitted in short bursts. It's suggested that there is a possibility of damage to internal organs.

There are other factors that are contributing to the EMR emitted by most fitness trackers – the number of LEDs on the device, the Bluetooth connection and the physical contact the tracker has with your body (such as not wearing it on your wrist). For example, the Apple Watch emits the highest percentage of EMR when it is attached to a user’s wrist. However, when it is placed on your lap, the EMR produced drops to a "negligible" amount.

How a Fitbit Works

If you are looking into the Fitbit activity monitor, you might have questions about how it works. This handy device monitors your daily activities and sleep patterns, and then syncs with the app on your smartphone to give you detailed feedback as to how you are progressing toward your goal.

If you are not sure about the Fitbit product line yet or you are not sure how the Fitbit device works, keep reading to learn more about this innovative technology.

One of the great things about Fitbit is the ability to track your steps and distance covered. The Fitbit monitors your movement and analyzes how many steps you make as well as how far you walked. You can identify your activity level and the number of steps you take in a single day. By doing this, you can become more aware of your activity level and how you can improve to meet your fitness goals.

As you progress, the Fitbit also becomes better at predicting your activity levels so it can be more accurate with its statistics. You can also set a goal and then track how you are doing towards that goal. This way, you can view how your activity levels are improving on a daily basis.

Fitbit Health Risks

Any electrical device that plugs in to an outlet or USB port can be considered dangerous or at least not safe by most standards. While you may not think of it this way, so-called “safe” watt usage can start to go over that limit when you’re using a Fitbit device.

And this assessment is based upon the Fitbit usage recommendations provided by the manufacturer.

The Fitbit platform is designed for users to develop a daily routine of walking 10,000 steps a day. Physical activity is a prescription for better health, and it’s considered safe most of the time. However, if you overdo it, your risk of physical injury increases. When you use a Fitbit, you’re considering it a “safe” workout. However, some reports suggest that use of the Fitbit can result in a possible high intensity, a dosage that’s not usually considered safe.

Using a Fitbit specifically can also reduce the amount of REM sleep you get at night. In some cases, it’s possible to reduce REM sleep to 40% lower than normal. This can have some serious health consequences as REM sleep is important for restoring your physical and mental health.

Does Fitbit EMF Radiation Affect Sleep?

The answer is generally yes. Ten minutes in front of a night-light, for example, will suppress melatonin by 72%. The repetitive pulses of electromagnetic radiation from your Fitbit also disrupt normal circadian rhythm, which has been linked to higher rates of cancer, depression, high blood pressure, and diabetes.

When it comes to improving sleep quality, wireless gadgets, including your Fitbit, are a distraction rather than a tool for good sleep. The Fitbit ones are known to give a lot of false positives and, if it senses a false positive, the Fitbit will vibrate and disturb you when you’re in deep sleep.

Generally, Fitbit EMF radiation doesn’t affect sleep quality, but when you’re wearing a Fitbit and you experience poor sleep quality, don’t give up! There are plenty of scientifically proven techniques you can use to improve your sleep quality. Try some of the sleep tips on this post or follow the guide in my book below.

Are Fitbit Rashes Caused By EMF Radiation?

Whether you have one or have had one, you might be wondering if a Fitbit rash is caused by exposure to EMF radiation. A Fitbit is a wearable device that tracks and records your activity level throughout the day. Fitbits mostly come in bracelet or clip designs, and they’re used to promote a healthier lifestyle and/or to assist in weight loss.

Fitbit Rashes versus Herpes

Since Fitbit rashes are so similar to herpes, you might be wondering if a Fitbit rash and herpes are the same thing. The truth is that even though your Fitbit rash is identical to a herpes outbreak, they are two different things.

The exact cause of Fitbit rashes is not known. It may be a cause of the way the Fitbit wire is cut so that it sits flush on the skin. It may be due to the material of the Fitbit or a sensitivity to the clip.

This is not common, and many people have worn their Fitbits without any problems. But if you’re getting a Fitbit rash or experience a Fitbit allergy, you may want to try the following things to treat it.

Do Fitbits Cause Cancer?

There’s been a lot of buzz in the news lately about Fitbit causing cancer. Fitbit lawsuits have popped up, stating that Fitbits cause a type of brain tumor called glioma and experts have claimed that the EMR (electromagnetic radiation) emitting from Fitbit wristbands could cause your brain cells to mutate or even become cancerous.

While we clearly don’t have any definitive proof that would rule out Fitbits as the cause of cancer, there is no actual evidence that the EMR emitted by Fitbit bands causes cancer. There are doctors who believe that EMR causes cancer but there are also many doctors, including the American Cancer Society, who think that EMR radiation is safe after a 15-year review of the evidence.

What Fitbit Has to Say About the EMF Radiation from Their Devices

Fitbit devices use radio frequency identification (RFID) technology to track activity, sleep, travel, heart rate, activity level, steps climbed and distance covered …. In some Fitbit models, the wireless syncing capability is built-in, so the device doesn’t need to be worn or carried to sync data.

Fitbit wristbands utilize Bluetooth to sync with your smartphone. Bluetooth short-range wireless communication technology was developed to replace cables and allow for wireless communication over short distances from fixed points. It was designed with a low-power form of radio wave-based wireless communications called Bluetooth.

In the case of Fitbit devices, the Bluetooth technology sends the activity information to your smartphone, which wirelessly transmits the information to the Fitbit servers.

In both the case of the syncing feature built-in to the Fitbit device, as well as the Bluetooth syncing, the device does not actively broadcast a signal when it is not syncing. When transmitting data, the Fitbit device uses the Bluetooth transmission protocol which transmits data to the smartphone at a maximum frequency of 2.4Ghz. All Fitbit devices that have Bluetooth functionality have a maximum power output of under 100 mw/cm – an extremely safe amount of power for short-range communication.

FCC Regulations on EMF Radiation: Can They Be Trusted?

Today’s technology is capable of measuring just about anything. We are now underwater in a murky pool of electromagnetic frequency (EMF) radiation. The Food and Drug Administration (FDA), the Federal Communications Commission (FCC), and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) have all done studies on the safety of EMF radiation. But these organizations have failed to take into account several things that are of a greater concern.

The reason why your phone produces EMF radiation is because it’s on the phone line. It has to use this energy to accurately send and receive signals. However, your body is a conductor better than any phone line could ever be. The reason why current EMF radiation standards allow for a much higher amount of radiation to be emitted from your body than from the phone is because you have 100 trillion times more cells than your average cell phone. Each cell is a mini antenna that holds the charge from the EMF radiation.

Minimize Exposure for a Healthier Life

There are so many tools available today to help you with your fitness goals. You can use fitness bands, apps on your phone, or even track your progress in online programs. These tools can help you reach your goals, but they aren’t without risk. One of the biggest concerns with the use of these fitness tracker tools is EMF radiation exposure.

EMF radiation exposure can be reduced, when you know where to focus. When you’re purchasing a fitness tracker, the most important thing you can do is to choose a model that’s least, not most, radiative when it’s on. Highly radiative fitness watches use wireless technology, like Bluetooth, to pair with other devices and transmit information. Also, the battery in the device produces a stronger signal than wristbands without a battery.

EMF radiation exposure can also be reduced if you disable the wireless technology. If you’re using an app on your phone or a browser on your PC to monitor your progress, you can choose to disable the radio frequency (RF). You can lose access to your data if you do this, but since you can easily access your data when you want to, it’s a good idea to shut off the wireless when you don’t need it.

Some Last Thoughts On Fitbit EMF Radiation:

There is no scientific evidence that suggests that EMF radiation harms humans. Yes, many scientists believe that there’s a correlation between cell phone and wi-fi radiation and negative health effects, but this only means that they think there’s a strong reason to push for further research. The fact that Fitbits are legally considered “safe” under the guidelines of relevant consumer safety laws means that Fitbits are considered to meet the standards (which are not aimed at health concerns).

The good news, however, is that most people don’t ever notice anything unusual. Fitbit radiation is still a risk, but the lack of evidence indicates that it’s a small risk. There are a couple of things you can do to reduce the risk. First, it’s important to place your handset as high on your waist as possible. There is less "space" between your body and your spine so radiation is less likely to reach your brain. Second, wear a Faraday metal mesh that will reduce radiation by around 90%.

Low EMF Saunas

The heat generated by the sauna can be beneficial to many health conditions ranging from rheumatic pain to reducing blood pressure and relieving stress. But if you are worried about the EMFs in the sauna, there are a few Saunas that are certified EMF low.

The Lemax Sauna

The SFR-100 gives off a very minimal amount of EMF that is consistent with that of what is naturally emitted in the environment. It is certified mobile and finished cabinetry helps to block out the least amount of EMFs at 95% success.

The Lemax Sauna is available in two models, a 6 person cabin model that can heat to 160 degree Fahrenheit from a full load of 50 degree Fahrenheit in less than 60 minutes, and a 10 person cabin that heats to 160 degree Fahrenheit from a full load of 50 degree Fahrenheit in less than 45 minutes.

Low EMF Hair Dryer

Most of us rely on hair dryers to get dry, silky hair for work, school, parties, or any social occasion. We usually don’t give a passing thought to the EMFs (electromagnetic fields) emitted from these trip devices, but we should.

EMFs, in small amounts, are absolutely harmless, but there have been studies linking excessive exposure to biological damage.

Of course, those studies are difficult to pinpoint and measure. It’s difficult to measure the effect EMFs have on the body because its reactions to radiation vary from person to person, making establishing harmful amounts trickier.

Research has shown that too much EMF radiation can cause headaches, fatigue, and muscle and joint pain. Increased EMFs are also linked to insomnia, depression, and a weakened immune system. It’s not a death sentence, by any means, and prolonged exposure can lead to chronic illnesses.

The different types of radiation that EMF emits.

Radio Frequency, or RF.

RF waves are the same type of waves used in FM radio and TV.


Microwaves are emitted from cell phones (iPhones, Blackberries, etc.) and can be absorbed by tissue in the body. These waves heat tissue and may cause DNA damage, asbestos-like lung scarring, and cancer

WiFi and other Wireless (Wireless is any device that does not have an electrical cord attached.)

If you have a laptop or desktop that is not wired to Ethernet lines, it’s possible that they are connected with WiFi, which is essentially radio frequency radiation.

Magnetic Field

All electrical devices create a magnetic field, and cochlear implants and other devices that emit electrical pulses also create a magnetic field.

Other Radiation

Any device that uses electricity emits some other form of radiation. This includes cell phones that are held to the ear, microwaves, digital watches, computers, fluorescent lights, etc.
