Fitbit wearables have become a popular choice for people looking to track their daily activities, exercise routines, and overall health. However, with the growing concern over the potential health risks associated with radiation exposure from electronic devices, many are questioning the safety of using Fitbit devices regularly. In this article, we will take an in-depth look at Fitbit radiation, its potential health risks, and ways to minimize exposure.

Electromagnetic Fields and Wearables

Radiation is a form of energy emitted by various sources, including the sun, electronic devices, and even some natural substances. There are two primary types of radiation: ionizing and non-ionizing. Ionizing radiation, such as that from X-rays or nuclear materials, can be harmful due to its ability to penetrate and damage tissues. Non-ionizing radiation, emitted by devices like Fitbit wearables, is generally considered less harmful, but it can still pose risks with long-term exposure. Health risks associated with radiation exposure can range from minor skin irritation to more serious concerns like cancer and reproductive issues.

Electromagnetic Fields and Wearables

Wearable devices like Fitbit generate electromagnetic fields (EMFs) through their use of wireless communication technology, such as Bluetooth or Wi-Fi. These EMFs emit radiofrequency (RF) radiation, which is a form of non-ionizing radiation. While Fitbit’s RF radiation levels are generally lower than those emitted by cell phones or Wi-Fi routers, it’s important to consider the cumulative exposure from all devices and the proximity to the body when assessing potential risks.

SAR Levels

While Fitbit does not publish the SAR levels of its devices, they claim that the SAR values are significantly below the maximum limit set by the FCC for cell phones, which is 1.6W/kg.

TriField TF2

For those who still want to know how much radiation their Fitbit produces, using an EMF meter is the best option. If you don’t already own one, I highly recommend the TriField TF2 meter. It can detect all three forms of EMF radiation and is known for its fast and reliable readings. For a comprehensive overview of other EMF meters, please refer to my guide to the Best EMF Meters for Any Budget.

Once you’ve obtained your EMF meter, you can measure the radiation output from your Fitbit device. To do this, take two measurements – one with the device powered off, and another with the device powered on. Place the EMF meter near the device to mimic its placement against your wrist and take a reading with the device off. This reading serves as your base measurement for comparison.

Now, power the device on and continue holding the meter near the Fitbit. Observe the values as they change and spike. The readings are likely to be fluid and will increase whenever the Fitbit sends out a Bluetooth signal. The highest value is the one to note.

By comparing the two measurements, you can find out how much radiation your Fitbit is exposing you to. This is an important step to take if you’re concerned about the potential health effects of EMF radiation exposure. For an example of how to do this, I recommend checking out the following video.

Overall, measuring the radiation output of your Fitbit is a crucial step in reducing your exposure to EMF radiation. By using an EMF meter and taking proactive measures to reduce exposure, you can help promote a healthier living environment for yourself and your loved ones.

Health Risks of Fitbit Radiation Exposure

The World Health Organization’s International Association for Research on Cancer recognizes RF-EMF radiation as “possibly carcinogenic to humans” based on a study in which rats exposed to radiofrequency signals developed heart and brain tumors. For a comprehensive overview of research into EMF radiation, please refer to my guide to the Top 30 Studies on EMF Radiation.

In addition to cancer, exposure to RF-EMF radiation has been linked to issues with sperm motility and quality in men, as well as an increased risk of miscarriage in women. Furthermore, some individuals experience a range of uncomfortable symptoms when exposed to even small amounts of RF-EMF radiation. This condition is known as Electromagnetic Hypersensitivity or EHS, and it can cause headaches, insomnia, fatigue, depression, itchiness, and rashes when wearing a Fitbit.

While the rashes some Fitbit users have complained of could be due to EHS, this has not been studied or proven. If you experience a rash, it’s best to discontinue use of your device and consult with a medical professional.

Overall, it’s important to be aware of the potential health risks associated with exposure to RF-EMF radiation. By taking proactive measures to reduce exposure, such as using lower-EMF devices and practicing whole-house protection, you can help minimize the risks to your health and well-being. Additionally, if you experience any symptoms or health concerns related to EMF radiation exposure, it’s always best to seek medical advice.

Protecting Yourself

Fitbit - Protecting Yourself

If you’re someone who has already invested in a Fitbit or is considering doing so, you may be wondering if there are ways to wear the device safely. While Fitbit does not allow you to disable Bluetooth on their fitness trackers, there are steps you can take to help lower the risk to your health.

  • Take the device off at night while you sleep. One simple step you can take is to take the device off at night while you sleep. Although the sleep tracking feature may be attractive, if you’re concerned about EMF exposure, it’s probably best to limit your use of this function. Sleep is a crucial time for the body to rest and regenerate, so anything you can do to minimize EMF exposure at night, including taking off your watch and storing it away from your bed, can be beneficial. If you still want to track your sleep, you can do so for a limited time and then return to the routine of taking off the watch before bed.
  • Opt for a lower EMF alternative. Another option is to opt for a lower EMF alternative. Several lower-EMF options are available on the market that allow you to disable WiFi and Bluetooth, resulting in a much lower-EMF experience. One such option is the Garmin Vivosmart HR, which allows users to track their steps, altitude, and heart rate while syncing with your phone at a later time. For other lower-EMF fitness trackers, check out our guide to Fitness Trackers Without Bluetooth.
  • Minimize your exposure elsewhere. In addition to taking these steps, minimizing your exposure elsewhere can also help reduce the risk of EMF radiation. Consider switching your home over to wired internet from WiFi, installing a smart meter cover, and taking other whole-house protection measures. For more information, check out our guide to Whole-House Protection.
  • Take supplements. Lastly, taking supplements, herbs, and vitamins can also be beneficial in protecting against radiation. One supplement in particular, Ginkgo Biloba, has been found to protect against RF-EMF radiation produced by devices like Fitbits. In a study on RF-EMF exposure and rats, those that received Ginkgo Biloba experienced less cell phone-induced oxidative stress. Taking a Ginkgo Biloba supplement may help reduce the risk of cancer and other health problems from RF-EMF exposure.
