Can Fitbit Cause Cancer: Get The Fact!

Do Fitbit Cause Cancer?

Fitbit users ask if Fitbits can cause cancer. Well, the rumors are lies because Fitbits are approved and safe to use.

Very little EMF Radiation from Bluetooth is emitted. Also, the power output of Fitbits ranges from 0.5% to 1%.

Radiations emitted by the Bluetooth feature in Fitbits like Charge 3, Fitbit Flex, Fitbit Sense, Fitbit Blaze e.tc, range from 800MHz to 2GHz.

Is Bluetooth Connection Bad For My Health?

The range of radiation from Bluetooth as mentioned above does not cause the body any harm. The radiation emitted by Bluetooth enables Fitbits to be non-ionizing.

This means the radiation cannot alter the bond between molecules and atoms forming your DNA. If it were to break the bond then diseases like cancer and tumor could be part of you.

Although scientists say the frequencies are low and hence safe for use, Healthcare persons are still not convinced that non-ionizing radiation is safe for your health and that’s why they are still researching the matter.

How to Turn Off Bluetooth On Fitbit

Switching off Bluetooth on Fitbit can’t happen. Fitbit connects to phones and PC through Bluetooth and that’s why disabling it on Fitbit is entirely impossible.

Fitbits can work independently but when it comes to downloading activity metrics they must be connected to either the smartphone or PC and the connection is only via Bluetooth.

Are There Any Other Side Effects Of Using My Fitbit?

Acquiring cancer as a result of using Fitbit is not true. On the other hand, the Electromagnetic Field, EMF from Fitbits causes wrist pain and skin irritation.

Users who are affected say they feel as if their skin around the wrist burns. But when they remove the Fitbit tracker from the wrist the sensation fades away after a while.

Other health complications that may happen as a result of electromagnetic radiation include swift mood swings, problems sleeping, not being able to pay attention, and feeling nauseous.

In case you are surely suffering from the above conditions then it would be best if you consider Fitness trackers without Bluetooth.

One of the best fitness trackers without Bluetooth is the Garmin Vivosmart HR Activity Tracker.

Best Fitness Tracker Without Bluetooth

Garmin Vivosmart HR Activity Tracker

Like Fitbit, Garmin Vivosmart HR Activity Tracker will keep track of the heart rate, sleep, calorie burn, count steps, elevation, and much more giving you results in real-time.

What differentiates the two is the need for Bluetooth. Fitbit must constantly emit radiation to stay connected to your phone or PC while Garmin Vivosmart HR Activity Tracker can sync with smartphones and PCs without constant radiation emission.

Get this right! The tracker has Bluetooth and which unlike Fitbit can be disabled. Although Vivosmart can track your workout without Bluetooth, the feature needs to be on when syncing information to your phone or PC.

Once the sync is complete, Bluetooth can be turned off and data viewed from the tracker with no issues.

The tracker can track activities without the radiation frequencies for up to 24 hours after which you will want to sync data to a phone or PC.

Garmin Vivosmart ensures the amount of EMF penetrating through the skin is reduced with the ON/OFF Bluetooth feature.

Here are two steps that will guide you to switch ON/OFF Bluetooth on Garmin Vivosmart HR:

  • Using your finger, tap, and long-hold the display and wait until the menu shows.
  • Choose the Bluetooth option and tap Turn Off. (Bluetooth is set to on by default).

The two sets are enough because by now your Bluetooth is off. To turn it back on, repeat the above steps.


Monitoring your daily workout to improve your health is not wrong. Fitness lovers will tell you, there is nothing as important as monitoring your workouts and that is true.

Being able to monitor your activities keeps you motivated. And when motivated you will want to even do more to beat the previous score and set up new goals.

By now you know Fitbits do not cause cancer but can be a recipe for other conditions. Lastly, using Fitbit each day is not safe for anyone because of the EMF.
