What you need to know about Fitbit Radiation

Given the amount of time that people typically wear these fitness trackers it is fair to ask.  Do Fitbits cause cancer?

Fitbit is one of the most popular fitness trackers out there. According to the US government guidelines for physical activity, the average adult should experience at least 150 minutes of moderate to vigorous physical activity every week. This requirement is probably what led to the invention of Fitbits. 


From the very simple Fitbit Zip to the Fitbit Versa smartwatch-style, millions of people use these devices to improve their health through heart rate monitoring, calorie tracking, and more.


In this article, we’re going to take a closer look at Fitbit's and discuss if they cause cancer. Also, we will go over some tips and tricks for protecting yourself from EMF radiation so that you can feel more secure when exposed.

What is a Fitbit?


What is a fitbit


Fitbits are wrist-worn health and fitness trackers that allow you to keep track of your every move. It offers users valuable information about their daily activities. 


Although its design mimics that of a traditional watch, it can do a lot more. Some of the built-in features include:

  • Keeping track of the number of hours you sleep
  • Monitoring the number of steps you take on a given day
  • Controlling your music player
  • Calculating the total calories burned
  • Caller ID display
  • Date and time display


This data is uploaded to individual user accounts on the Fitbit website. It connects wirelessly to other devices such as smartphones via Bluetooth.

How a Fitbit Works

Fitbits have sophisticated algorithms and built-in sensors that you can use to add and analyze various metrics. Users can view biostatistics such as the number of calories burned, heart rate, and the total amount of physical activity on a given day. 

For example, the altimeter sensor can indicate whether you are going up or downstairs. The three-axis accelerometer tracks the total number of steps you take in a day. Both can convert these movements into digital measurements as soon as the device is placed on the body. 

Fitbits use intelligent technology that can differentiate between various movements, e.g. running 8 km vs. driving for the same distance. This will give you an accurate record of how much time you spend on the go.


Can Fitbits Cause Cancer?


Do fitbits cause cancer?


Fitbits themselves don’t cause cancer, but the electromagnetic field radiation they give off can certainly pose a risk.

Studies have been conducted linking both non-ionizing radiation and cell phone usage to the development of cancerous tumors. Short-term exposure to electromagnetic radiation is unlikely to lead to cancer development. The danger arises when you are exposed to electromagnetic radiation for a long time.


Unfortunately, that’s how we interact with devices like Fitbits. We wear them on our wrists for long periods. Some users never want to remove them.


Long-term use and exposure to EMF radiation in this way can increase the risk of developing a particular type of cancer.

For example, cell phones, cell towers, and Wi-Fi routers emit much more electromagnetic radiation than Fitbits, which makes them more dangerous. However, a Fitbit is worn directly on the body for a long time. This direct contact increases the risk of cancer with Fitbit watches.


For instance, studies have shown that in certain cases cell phone use has been correlated with the development of cancer called glioma, which develops on the same side of the brain as the side where the user most frequently places their cell phone. 


This is because the radiation was concentrated in one area and the additional work led to the development of cancerous cells. Most people use their cell phones in direct contact with their heads when answering a call.



Prolonged use Equals Prolonged Exposure

Now imagine that you pick up your cell phone and hold it to your head all day and night for an extended period. This is obviously not practical or safe. Although the mobile phone can emit more radiation than the Fitbit, both present the same risk if they are left in contact with the body for long periods.

Is it Safe to Wear a Fitbit to Bed?

No! This is because wearing a Fitbit at night inadvertently reverses all of your gains during the day when you attempt to lose weight. 

Experts recommend turning off all wireless sources at night before bed. As we know, sleep is an essential part of our body’s renewal system. When we sleep well, we feel better on many levels. 

Now it is said that the average person sleeps around 230,000 hours of their life. This is an extensive amount of time and represents about a third of your total life. This only shows the extent of its importance.


Since we spend much of our life sleeping, we must get the best possible quality of sleep, as this is the nighttime opportunity for our body to repair and revitalize itself from our daily work and stress. 


A good night’s sleep can greatly improve your overall health and well-being. Our concentration, awareness, and productivity for the next day are determined by the time and quality of sleep we got the night before.

That is why, after a short or interrupted night’s sleep, we wake up dizzy, restless, and in some instances worse than before going to bed.


Wearing a Fitbit to sleep every night can increase the chances that you will wake up restless or lazy the next day due to the constant EMF radiation it emits. 



How Does EMF Exposure Affect Sleep? 


EMF exposure and sleep


Electromagnetic radiation has been proven to alter our natural sleep patterns. This occurs because the body actually reads the electrical nature of electromagnetic radiation as a type of light. When your pineal gland detects this light, it produces less melatonin (the hormone our body produces to regulate alertness and sleep), which ultimately leads to poor sleep.

In fact, the University of Melbourne, Australia, found exactly that in a research study and concluded that: “... the results show the importance of melatonin disruption due to exposure to low levels of electromagnetic fields has been shown to have a greater impact on sleep quality than daytime exposure”. 

This is probably because at night our body tries to go to rest, while the EMF radiation you are exposed to keeps the body more alert and in an inflamed state.

Are Fitbit Rashes Caused by EMF Radiation?

There have been many growing complaints from Fitbit users about developing a rash within a few weeks of using the device. 


This is no accident, as skin irritation is one of the common symptoms of electromagnetic hypersensitivity (EHS). 


In 2014, the company recalled Fitbit Force after thousands of users complained that the device caused rashes and other skin irritations. However, the company attributed it to an allergy to an alloy the bracelet was made from, a claim that users have categorically refuted. 

Also, many of them reported deep tissue pain that did not set in until after they started using the device. Even more surprising, similar complaints continue to be reported as new versions of Fitbit are released.

The company is unlikely to continue making devices that contain the same irritants that were responsible for the widespread allergic reactions that plagued its customers.

How to Protect Yourself from Fitbit EMF Radiation



Now that we’ve covered many issues with devices that emit electromagnetic radiation, including Fitbits, it is time to look into some ways you can protect yourself from some of the harmful effects. 

Nowadays, it is almost impossible to avoid exposure to at least some level of EMF radiation (which again, in small amounts, is usually not harmful).

However, there are ways to increase our protection if we are in an environment where the electromagnetic radiation may be slightly higher, or if we want to continue enjoying the comfort that Fitbits offer us.


  1. Limit usage

One of the easiest ways to reduce exposure to electromagnetic radiation is to simply limit the use of the devices that emit it – your Fitbit watch in this case. While Fitbit watch is meant to be worn for long periods, you don’t have to wear them all the time to get the same benefits of wearing one. 


Try to use your Fitbit only when you plan to exercise during the day. If you use yours to keep track of how many steps you’ve taken during the day, it is a good idea to remove your watch while relaxing at home or watching TV on the couch. 


Remember that prolonged exposure to electromagnetic radiation will cause problems. Therefore, wearing your Fitbit for a short period should not cause cumulative problems or damage.


  1. Use EMF Protection Devices

Believe it or not, certain minerals neutralize electromagnetic radiation. In other words, they create something called a paramagnetic field around them, which turns the structure of artificial EMF radiation into a form of radiation that is more natural and less harmful to the body. 


One of such is the Geoclense Orgone Negative Ion Generator. This EMF protection device consistently generates healthy beneficial Negative ions that work by harmoniously neutralizing your entire property and home all the way to its boundaries, counteracting each one of these destructive energies such as radiation and electromagnetic frequencies from your Fitbit.


  1. Consider a Digital Pedometer

Another step you can take to avoid exposure to electromagnetic radiation while tracking your steps is to use a digital pedometer to track your activity levels instead of a Fitbit. 


Sure, they might not have all the bells and whistles a Fitbit watch has, but they are a lot safer if that’s your main concern. They don’t give off Bluetooth or electromagnetic radiation, so you can leave them on anytime you want. 


Some people may need more drastic measures if they want to continue using devices that emit electromagnetic radiation. There is one disorder that has received more attention lately as electromagnetic hypersensitivity or EHS.



There is nothing wrong with wanting to track your daily activities in order to improve your health. If this can be done without the help of digital devices, then this is exactly what you need to do. 

Fitbits can help you lose weight and stay in shape, but they can also create a recipe for conditions that may be the least of your worries about being overweight.

 Unfortunately, the EMF radiation from a Fitbit is not safe for everyday use. Even at so-called “low” non-ionizing concentrations, prolonged exposure inevitably leads to cancer development.
