Recent research from the University of Notre Dame has revealed alarming levels of per- and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals,” in smartwatch and fitness tracker bands, raising significant health concerns for users.

The study, published in Environmental Science & Technology Letters on December 18, 2024, tested 22 different wristbands purchased in the U.S. and found that nine of them contained elevated levels of perfluorohexanoic acid (PFHxA), a specific type of PFAS.

Key Findings

The researchers discovered that many of the tested bands were made from fluoroelastomers, synthetic materials prized for their durability, flexibility, and resistance to sweat and skin oils.

However, these same properties have led to concerns regarding potential health risks associated with prolonged skin contact.

Notably, higher-priced bands—those costing more than $15—were more likely to contain significant amounts of PFHxA. Some samples even exceeded 1,000 parts per billion (ppb), with one band showing concentrations above 16,000 ppb.

Health Implications of High PFAS Levels in Smartwatch Bands

PFAS are notorious for their persistence in the environment and human body, earning them the nickname “forever chemicals.” Exposure to these substances has been linked to various health issues, including hormonal disruption, developmental delays, immune system suppression, and increased cancer risk.

Given that approximately 21% of Americans wear smartwatches or fitness trackers for over 11 hours a day, the potential for skin absorption raises serious concerns about long-term health effects.

Graham Peaslee, a professor emeritus at Notre Dame and co-author of the study, emphasized the unprecedented concentrations found in wearable technology.

“We have never seen extractable concentrations in the part-per-million range for any wearable consumer product applied to the skin,”

he stated.

This discovery highlights the need for increased scrutiny regarding materials used in consumer products.

Expert Recommendations for Using Low PFAS Smartwatch Bands

In light of these findings, experts recommend that consumers consider opting for lower-cost silicone bands as a safer alternative to fluoroelastomer bands. The study’s lead author, Alyssa Wicks, urged consumers to be cautious about their choices when purchasing fitness trackers and smartwatches.

Consumer Awareness and Industry Response

The implications of this research extend beyond individual health concerns; they also call for greater transparency from manufacturers regarding the materials used in their products.

As awareness grows about the presence of PFAS in consumer goods, there is an urgent need for comprehensive testing and regulation within the industry.

The study included popular brands such as Apple, Samsung, Fitbit, and Google.

While a complete list of tested watchbands is not publicly available, it underscores the importance of scrutiny across all brands and price ranges.

As consumers increasingly rely on wearable technology for fitness tracking and health monitoring, understanding the potential risks associated with these devices becomes crucial.

The findings from this study serve as a wake-up call for both consumers and manufacturers alike. With ongoing discussions about environmental safety and personal health risks linked to PFAS exposure, it is essential for individuals to make informed decisions about their wearables while advocating for regulatory changes that prioritize safety in consumer products.
