A new study from researchers at the University of Notre Dame reveals a hidden concern: wristbands on fitness trackers and smartwatches might expose you to harmful “forever chemicals” (PFAS).
Many high-end bands are made with fluoroelastomer, a material prized for its strength, flexibility and resistance to sweat. However, products made with this material contain toxic PFAS linked to health risks like cancer, immune system suppression and developmental harm. What’s worse, PFAS are found in almost every product tested, even in bands that don’t advertise fluoroelastomers.
If you’re concerned about exposure to PFAS in smartwatch and fitness tracker bands, here are steps you can take to reduce your risk:
> Choose silicone bands. Researchers suggest opting for silicone bands instead of fluoroelastomers, since silicone bands were found to have little to no detectable PFAS.
> Read product descriptions carefully. When shopping for higher-end bands, check the product labels. Avoid bands made with fluoroelastomers, which are more likely to contain PFAS.
> Limit wear time. If you’re worried about exposure, consider taking off your smartwatch during sleep or long periods of inactivity.
> Push for safer alternatives. Support efforts to hold manufacturers accountable by advocating for more transparency and the use of safer, well-regulated alternatives to PFAS in products.
