Scientists reveal that smartwatch straps made of fluoroelastomer may contain chemicals that are harmful to health.
A study published in the scientific journal Environmental Science & Technology Letters revealed that the bracelets of many smartwatches and smartbands on the global market contain significant concentrations of substances known as “forever chemicals” or PFAS (per- and polyfluoroalkyl substances). These chemicals are highly resistant to age and degradation, which is why they are called “forever chemicals.” Although they are durable, these compounds can contaminate the skin and pose risks to human health and the environment as they accumulate in the body over time.
The chemicals present in the material of smartwatch straps
Those chemical are present in smartwatch straps produced with materials such as fluoroelastomer, a type of silicone widely used by the main manufacturers of wearable devices.
Although smartwatches are designed to make people's lives easier, the presence of chemicals in these products can affect the health of those who use them frequently, especially during physical activities, when sweat can further facilitate the absorption of these compounds through the skin.

The study looked at different smartwatch models, spanning a variety of brands and price ranges.
The common point between the models was the material used in the straps: fluoroelastomer.
This material is popular for its strength and flexibility, and is chosen by several major smartwatch manufacturers.
Fluoroelastomer is a type of silicone used to ensure comfort and durability in wristbands, but research has found that it contains a high concentration of perfluorohexanoic acid (PFHxA), a type of PFAS.
These chemicals are known to be difficult to remove from the environment and can build up in the body over time.
The researchers pointed out that, by using bracelets made of this material, users may be exposing themselves to risks.
These chemicals can be easily absorbed through the skin, especially during physical activity, when sweat can accelerate this absorption process.
This prolonged exposure can lead to contamination of the body and increase the risk of health problems such as cancer and high cholesterol.
Possible risks of contamination with Smartwatches
Although the researchers did not disclose the specific brands analyzed, they highlighted that smartwatch straps made with fluoroelastomer are common in products from popular brands.
These devices are available in various price ranges and are used by millions of people around the world.
The problem is that, even with the popularity of these devices, the chemicals present in the bracelets can be harmful to your health.
Perfluorohexanoic acid (PFHxA) found in wristbands is one of the main chemicals present in many smartwatches and smartbands, and its presence can pose a contamination risk.
Despite its durability, this material and the chemicals it contains are a growing concern, especially since the chemicals can build up in the body over time.
Safer alternatives to avoid contamination
To reduce the risks of exposure to chemical, manufacturers already offer safer alternatives.
Some of them have started to offer bracelets made from materials such as nylon fabric or natural rubber, which are more reliable options for those who practice physical activities and want to avoid exposure to fluoroelastomer.
These materials do not contain the everlasting chemicals found in traditional smartwatch straps.
Additionally, consumers can opt for bracelets made of safer materials and avoid exposure to potentially harmful chemicals.
Although most wristbands made with fluoroelastomer are durable and comfortable, the risks of contamination and health problems associated with the constant use of devices with these compounds make it important to consider these alternatives.
Consumers should pay attention to the material composition of their smartwatch straps.
The study reinforces that, if possible, it is recommended to avoid using bracelets made with fluoroelastomer, as they may contain chemicals that, over time, can contaminate the skin and body.
By opting for alternative materials, the risk of exposure to eternal chemicals can be minimized, promoting a safer choice for your health.
