A recent study published in the American Chemical Society’s Environmental Science and Technology Letters has raised significant concerns regarding the presence of “forever chemicals,” or PFAS (per- and polyfluoroalkyl substances), in everyday items used by triathletes, particularly watch bands. This revelation underscores the need for increased awareness regarding the materials we frequently wear and their potential health effects.
PFAS are a group of synthetic chemicals recognized for their severe environmental persistence and notable presence in the human body. With a composition of over 14,000 individual compounds, these substances are commonly found in a wide variety of consumer products, such as stain-resistant fabrics, food packaging, cosmetics, and non-stick cookware, making them ubiquitous in modern life. However, research has consistently linked PFAS exposure to serious health concerns like multiple cancers, immune system suppression, and liver damage.
Study on PFAS in Watch Bands
The recent study examined 22 watch bands from various brands, including popular models from Apple and Fitbit. Researchers sourced these bands from Amazon, Best Buy, and donations. Alarmingly, 15 of the bands were found to contain PFAS, often at very high concentrations. Notably, researchers detected [PFHxA](https://pubmed.ncbi.nlm.nih.gov/33221613/), a specific PFAS compound, at levels significantly higher than those recorded in other consumer products like cosmetics or food packaging.
Health Risks of Wearing PFAS-Containing Watch Bands
Triathletes and fitness enthusiasts frequently wear these bands for extended durations, which presents a concern for skin absorption. The study indicates that wearing these bands for over 12 hours daily can provide ample opportunity for PFAS to penetrate the skin, especially during physical activities that lead to sweating. Graham Peaslee, a professor emeritus at the University of Notre Dame and a corresponding author of the study, asserts that prolonged exposure is a likely outcome for those who wear these products regularly.
The Reality of PFAS Exposure
It is important to note that almost everyone in North America already has PFAS in their bloodstream, a legacy of decades of widespread use since the 1950s. Peaslee emphasizes that while the discovery of PFAS in watch bands may be alarming, individuals are continually exposed to various chemicals in their daily lives. The key takeaway for consumers is to be informed and proactive when purchasing new products.
How to Assess Your Watch Band for PFAS
If you own a smartwatch or fitness tracker, it’s essential to check the materials of your watch band. Look for mentions of fluoroelastomers, fluorine, or abbreviations like FKM, FEK, FEKK, and FEKM, which indicate the presence of PFAS. Brands like Garmin have committed to eliminating specific PFAS from their products, but this does not guarantee that all their bands are free from these chemicals. For safer options, look for bands made from silicone, nylon, or leather, which are less likely to be treated with PFAS.
Choosing PFAS-Free Alternatives
As awareness of PFAS in consumer goods grows, it’s wise to replace any questionable watch bands with options known to be PFAS-free. The recent research indicates a correlation between band price and the presence of PFAS; lower-priced bands (under $15) tend to be safer as they usually don’t contain fluoroelastomers. Opting for bands made from silicone or nylon is a smart choice, and consumers should look for emerging labels indicating “PFAS-free” or “fluorine-free” products.
The Future of Consumer Awareness and PFAS Regulations
The prospect of increased regulation surrounding PFAS is on the horizon, with proposals for bans on certain compounds already being discussed internationally. As consumers, staying educated and making informed purchasing decisions can significantly impact personal health and public policy regarding the use of harmful chemicals in everyday products. Consider researching and advocating for greater transparency on ingredients in all consumer goods, including watch bands, to promote a healthier future.
