SOUTH BEND, Ind. — A startling revelation has emerged from recent research: high-end smartwatch wristbands may contain harmful chemicals known as PFAS, or “forever chemicals,” which pose significant health risks. The University of Notre Dame has spearheaded this discovery, urging consumers to reconsider thier purchases.
PFAS, or polyfluoroalkyl substances, are synthetic compounds used extensively in products ranging from cosmetics to firefighter gear. These chemicals, numbering around 14,000 variants, are notorious for their persistence in the habitat and human body, earning the moniker “forever chemicals.” The specific variant found in smartwatch wristbands, fluoroelastomer, is commonly used in premium brands for its durability, flexibility, and sweat resistance.
Professor Graham Peaslee, leading the study at Notre Dame, highlights the alarming health implications. “These chemicals are linked to increased risks of cancer, liver and thyroid disorders, and immunosuppression,” he warns. Despite mounting evidence of their dangers, regulations in North America remain sparse, leaving consumer awareness and choice as the primary defense.
“We don’t have funding to go and measure everybody’s wristband, but we do have enough to measure enough of them to say, hey look this is an issue. Manufacturers shouldn’t be doing that, and they’ll swing away from it the next year or two. But until that’s done, we should try to alert consumers and the consumers have a really powerful voice. If they stop buying fluoro elastomers, then they’ll stop making them,” said Peaslee.
The research began after Peaslee and his team noticed advertisements for smartwatch wristbands boasting sweat-resistant properties due to fluoroelastomers. They purchased 22 bands for analysis, revealing a troubling pattern. “So if you buy a $30 or more watch band, not the watch, just the band, then you’re much more likely to have a fluoro elastomer in it,” Peaslee explains.
These chemicals don’t just affect wearers—they linger in the environment for centuries. “But if they all end up in the garbage eventually, and they will end up in our local landfill. These forever chemicals will last for hundreds of years. they’ll pass out of the landfill leachate into the drinking water or irrigate our food,” Peaslee emphasizes, underscoring the long-term ecological impact.
What makes this PFAS variant particularly hazardous is its elusive nature in the bloodstream. “That one particular PFAS has escaped scrutiny for a very odd reason. When it gets into your blood,it doesn’t stay in the blood’s serum,which is what everybody measures,” Peaslee notes,highlighting the challenge in detecting and regulating it.
While Europe is moving toward stricter regulations, North america lags behind. Peaslee advises consumers to opt for safer alternatives.”I would suggest that you look at a manufacturer’s website to see what type of watchband, if it’s an expensive one, if it’s a cheap one, if it says silicone or it says it’s leather or it says it’s a type of fabric, you’re probably quite safe,” he recommends. Budget-pleasant options,particularly those under $15,were largely found to be free of the chemical.
This discovery underscores the importance of informed consumer choices. By avoiding high-end wristbands made with fluoroelastomers, individuals can protect their health and contribute to reducing the environmental burden of these persistent chemicals.
Given that PFAS can leach from smartwatch wristbands, what are the potential health risks associated with prolonged exposure to these chemicals through skin contact?
Interview with Dr. Emily Carter, Environmental Health Expert
Topic: PFAS in Smartwatch Wristbands and Consumer Safety
Host: Archyde News Editor
Archyde News Editor: Dr. Carter, thank you for joining us today. Your expertise in environmental health is invaluable, especially given the recent findings from the University of notre Dame regarding PFAS in smartwatch wristbands. Can you start by explaining what PFAS are and why they’re called “forever chemicals”?
dr.Emily Carter: Thank you for having me.PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals designed for durability. They’re used in a wide range of products, from cosmetics to industrial gear, because of their resistance to water, oil, and heat. The term ”forever chemicals” comes from their persistence—they don’t break down easily in the surroundings or the human body, leading to long-term exposure and potential health risks.
Archyde News Editor: The research suggests that high-end smartwatch wristbands contain elevated levels of leachable PFAS. What does this mean for consumers who wear these devices daily?
Dr. Emily Carter: It’s concerning. PFAS can leach from materials like wristbands, especially under conditions of sweat or friction, and enter the body through the skin. Chronic exposure to PFAS has been linked to health issues such as hormonal disruptions, immune system suppression, and even certain cancers. The fact that these chemicals are present in wearable tech, which is in constant contact with the skin, raises significant alarms.
Archyde News Editor: The University of Notre Dame is urging consumers to reconsider their purchases. Do you think this is a call for immediate action, or is more research needed before we draw conclusions?
Dr. emily carter: Both. The findings are robust enough to warrant immediate consumer awareness and caution. However, we also need more research to understand the exact levels of PFAS leaching, the specific health risks posed by smartwatch wristbands, and safer alternatives. In the meantime, consumers should be informed and consider products labeled as PFAS-free, or those made with natural materials.
Archyde News Editor: With around 14,000 variants of PFAS, how do we regulate or manage exposure to these chemicals in everyday products?
Dr. Emily Carter: It’s a complex challenge. Regulation has been slow because of the sheer number of PFAS variants and their widespread use. Though, agencies like the EPA are increasingly prioritizing PFAS restrictions. Consumers can also play a role by demanding openness from manufacturers and supporting brands that prioritize safety over convenience.
Archyde News Editor: What steps should consumers take to minimize their exposure to PFAS in wearable tech and other products?
Dr. emily Carter: Frist, educate yourself. Look for products explicitly marketed as PFAS-free. Second, consider alternatives—natural materials like leather or silicone are often safer. Third, advocate for change by supporting policies and companies that aim to reduce PFAS use. Lastly,if you’re concerned about exposure,consult your healthcare provider for personalized advice.
Archyde News Editor: Thank you, Dr. Carter,for shedding light on this critical issue. It’s clear that awareness and informed choices are key to safeguarding our health against PFAS exposure.
Dr. Emily Carter: Indeed, staying informed and proactive is the best way forward. Thank you for the possibility to discuss this important topic.
