Recent studies have raised concerns about the presence of per- and polyfluoroalkyl substances (PFAS), often called “forever chemicals,” in Apple Watch wristbands. These findings have sparked discussions about everyday exposure to these potentially harmful substances and their long-term health effects.
PFAS in Apple Watch Wristbands
A recent study conducted by the University of Notre Dame in 2025 examined smartwatch and fitness tracker wristbands from various brands, including Apple Watch bands. The research revealed that 15 out of 22 wristbands tested contained high levels of PFAS, particularly in those made from fluoroelastomers—a synthetic rubber known for its durability and resistance to sweat and oils.
Because wristbands come into direct contact with the skin for prolonged periods, there is concern that PFAS could be absorbed dermally. Long-term exposure to these chemicals has been linked to serious health issues, including liver damage, thyroid disorders, and reproductive problems. If you’re concerned about PFAS exposure from your Apple Watch band, opting for alternative materials like silicone, fabric, or leather may be a safer choice.
Apple’s Response and Future Considerations
As a tech giant, Apple has a strong commitment to sustainability and reducing harmful materials in its products. While the presence of PFAS in Apple Watch bands raises concerns, the company may take steps to address these findings in future product designs. Apple has previously made significant efforts to remove toxic substances from its devices, such as eliminating mercury and lead from displays.
Customers can look forward to potential innovations in Apple’s product lineup that may include PFAS-free materials in future smartwatch bands. Meanwhile, consumers who are concerned about exposure can choose third-party bands made from natural or PFAS-free synthetic materials.
How to Reduce Your Exposure
Given the growing body of evidence surrounding PFAS exposure, here are some steps you can take to minimize risk:
Consider switching your smartwatch band to materials like silicone, leather, or fabric if you’re concerned about potential PFAS absorption through the skin.
Stay informed about Apple’s environmental initiatives and potential product updates regarding material safety.
Choose third-party accessories carefully, ensuring that they are made from PFAS-free materials.
As awareness of PFAS contamination continues to grow, consumers can make more informed decisions about the products they use daily. Understanding potential risks and making small changes can help reduce exposure to these persistent chemicals.
