BEWARE the toxic trap: Is your sports watch band leaking harmful chemicals?

(NaturalHealth365)  Sports watch bands are a popular accessory for fitness enthusiasts and smartwatch users alike, offering both style and functionality.  However, a hidden downside may come with wearing these everyday (wireless) devices.

A recent study published in ACS Publications reveals that the very band wrapped around your wrist could contain harmful substances, raising concerns about potential health risks.

The growing alarm surrounding sports watch bands

The more we learn about sports watch bands, the less appealing they become.  Growing evidence suggests that these everyday accessories may leak harmful chemicals, with smartwatches posing a greater PFAS risk than previously assumed.  Of course, we should not ignore the risk of wireless radiation that is produced by many of these products, as well.

PFAS, often called “forever chemicals,” are particularly concerning because they absorb into the skin at higher rates when the body perspires.  This is especially problematic for individuals who wear sports watches during exercise – the group most likely to monitor their health and fitness with these devices.

Smartwatches have become quite popular for tracking heart rate, steps, and sleep while also serving as reminders for elderly and sedentary individuals to stay active.  These benefits have fueled the industry’s growth, with smartwatch sales surpassing half a billion in 2024.

Despite their rising popularity, the public should know that most sports watch bands contain PFAS at levels high enough to warrant concern.  Given the links between PFAS exposure and serious health issues – including cancer, infertility, and autoimmune diseases – manufacturers must take action to address this hidden risk.

Avoid sports watch bands with fluoroelastomers and PFHxA

A recent study analyzed 22 sport watch bands from various brands, revealing a concerning trend 15 of the 22 bands contained more than 1% fluorine.  This suggests that fluoroelastomers, a specialized synthetic rubber, are present in nearly all sports watch bands on the market.

Researchers used advanced particle-induced gamma-ray emission spectroscopy to scan the bands’ surfaces for PFAS.  While fluoroelastomers are prized for their durability and resistance to sweat and skin oils, their harmful chemical components can leach into the skin over time.

The risk increases during exercise when sweat pores open, allowing PFAS to penetrate deeper into the skin and potentially enter the bloodstream.  As a result, these watch bands may pose a greater health risk when worn during physical activity.

The study also found high concentrations of perfluorohexanoic acid (PFHxA) in many smartwatch bands.  While PFHxA is regulated in Europe, it remains legal in products sold in the United States.  This chemical is particularly alarming because it disrupts the endocrine system, affects liver function, and compromises blood cells by binding directly to red blood cells.

How to reduce your exposure

Interestingly, the study found that higher-priced smartwatches were more likely to contain harmful chemicals.  Watches priced under $15 had fewer contaminants, while those in the mid-range ($15–$30) were also less likely to contain PFAS than watches over $30.

To minimize exposure:

• Carefully check product labels before purchasing a smartwatch band.  If PFAS-related chemicals are listed, consider a safer alternative.
• Opt for more affordable bands that may contain fewer harmful substances.

As smartwatches continue to grow in popularity, consumers must be aware of the potential risks associated with PFAS-laden watch bands.  With mounting evidence of their harmful effects, manufacturers must take responsibility and seek safer materials for wearable technology.

As a safer alternative, select a watch band that is made from nylon or leather.
