Can wearing a Fitbit or Garmin activity tracker cause burns?

While Fitbit products are ubiquitous, and others like Garmin, Fitbit also has a good track record for providing quality products that don’t suffer from the same pitfalls as other brands. Personally I also love the Fitbit activity tracker, which tracks some of your daily activity without requiring you to take a separate step counter. The one drawback is that Fitbit products are currently limited to communicating with only one other Fitbit device, so there is no way to track activity from more than one device, unless you purchase an additional one. This can be a drawback if you own a Fitbit activity tracker, but also potentially a benefit if you are looking to track activity from multiple Fitbit devices at the same time.

The majority of Fitbit and Garmin users will know that many different types of sensors can be worn to monitor things like sleep and movement. These devices are often worn on the body, but some can also be worn on the wrist. Some people use these devices to monitor their sleep patterns, and to ensure they are not getting too much sleep. Others will use them to monitor their steps taken, calories burned and even their heart rate.

It is thought that friction between the band (like a Fitbit or a Garmin) and your skin can generate heat, causing skin damage. However it’s not clear whether the heat from the band is enough to cause burns. This is because Fitbit and Garmin use a sensor that generates a small amount of heat when it is used in a certain way. It’s thought this is enough to cause a burn if it is used for extended periods of time.

Health and safety are two priority for every electronic equipment, and they are often subjected to rigorous internal and external testing, but there are always situations that may go wrong. Because activity trackers and smartwatches are intended to be worn on the wrist and are battery-powered and heat up naturally owing to internal components, physical injury is a distinct risk.

Can a Fitbit or Garmin activity tracker cause skin burns as a result of this?

The majority of skin irritation experienced by Fitbit or Garmin activity trackers is caused by contact dermatitis, a dermatological disease produced by foreign objects rubbing on the skin for extended periods of time. If the battery of an activity tracker starts to overheat, it may cause burns.

Outright burns are not as frequent as skin irritation, which is the real cause of irritation. However, for a number of reasons, burns are conceivable with an activity tracker. This article will go through the many kinds of irritations and even burns that may occur while wearing a Fitbit or Garmin activity tracker. Continue reading to learn why these irritations arise and how you may avoid them in the future.

Is it possible for a Fitbit to cause burns?

A complaint emerged in 2019 from a guy who said he awoke in the middle of the night with severe burning and tingling pain in his wrist. Early the next morning, he reported that his Fitbit activity tracker was burning his skin, which was verified by emergency care personnel. The user has third-degree burns and will need a skin transplant to repair the harm caused by the activity tracker.

This is clearly frightening and sad, but batteries in smart gadgets such as the Fitbit activity tracker may pose hazards. Not only can activity trackers produce radiation that may be detrimental to your health in the long run, but a faulty activity tracker battery can also have some very severe repercussions.

Bluetooth radiation, which is a result of low-frequency EMF radiation, is emitted by both Fitbit and Garmin activity trackers. However, with an activity tracker, burns are caused by the active battery overheating, which is needed to power the tracker’s smart functions.

Because the above-mentioned incident happened while a user was sleeping, many people are asking whether sleeping with a Fitbit is safe. This is completely dependent on the quality of the battery that you keep in your Fitbit gadget. An overworked and continuously operating battery may create problems with the internal components of the battery that power the smart features.

Furthermore, most Fitbit and even some Garmin activity trackers contain nickel, which may cause severe skin irritation and even burns when worn on the wrist for long periods of time. When nickel irritation on the skin is combined with radiation from the gadget, the result may be wrist burns.

Why is my Fitbit making me sweat?

Although a Fitbit radiation burn may seem unlikely, it is completely feasible. It’s also essential to realize that the word “burning” may mean different things depending on who you ask. Fitbit tingling or irritation to the skin on the wrist might be the real issue. Nickel, which makes up a significant part of the device’s chemical composition, has been known to produce rashes and blisters, which some users may mistake for burns.

However, if your Fitbit is burning your arm, as the guy in the linked story said, it’s most likely due to a defective battery or a collision of nickel and radiation that’s actively burning into the flesh.

Is it Possible for a Garmin Activity Tracker to Cause Burns?

Garmin’s watches and fitness trackers have also been known to cause skin irritation and even mild burns in the past. Garmin has made aggressive efforts to solve some of the issues that may lead to skin burns, in my opinion.

If you’re worried about potential burns or have a nickel allergy, the Garmin Vivosmart 4 with its nickel-free construction and improved band comfort is a fantastic option.


Is it possible for a Fitbit battery to cause skin burns?

When compared to non-smart device batteries, smart device batteries have an exponentially higher potential to overheat. An activity tracker is in charge of detecting and collecting large quantities of data, as well as transmitting the information through Bluetooth to other devices. Batteries are responsible for supplying power, and just like any other electronic equipment, a battery is only as powerful as the device it powers.

If a battery is kept on for too long or isn’t properly charged and let to rest, it may overheat and cause burns on the skin surrounding the wrist. Furthermore, even while using the activity tracker during typical activities, the battery may cause skin to burn. This is similar to what would happen if you placed your palm on a car’s hood after a lengthy drive through the city.

The primary function of a battery is to provide the life of the item it is entrusted with powering, because power and velocity generate heat. When you are not actively using your Fitbit gadget, switch it off to avoid potential battery burn. Also, make sure the battery is as completely charged as possible.

Why does Fitbit irritate my skin?

A Fitbit fitness tracker may irritate your skin in a variety of ways. The most apparent method is by pushing the device against the skin, which may irritate the skin more due to perspiration. When using an activity tracker, nickel reactions and battery burns are also possible.


In conclusion, a Fitbit activity tracker, as well as certain Garmin activity tracker devices, may cause skin burns. Before you buy anything, be sure you don’t have a nickel allergy. Additionally, make sure to look after your battery and allow your gadget some downtime to avoid battery problems in the future.

Activity trackers may be absolutely safe gadgets to use if you keep this in mind.

Wearing any activity tracker or Fitbit to bed for extended periods of time can be dangerous, as the activity tracker can cause friction between the tracker and your skin that can increase the risk of burns. According to the American Academy of Dermatology (AAD), the risk of a Fitbit or other activity tracker burn is greater for southerners, individuals who have a history of skin cancer , and those who tend to sleep on their side or stomach. Avoid putting your Fitbit or other tracker on your hip or the bottom of your foot, as the area is less likely to get friction burns..
