A recent study reveals that many smartwatch bands contain perfluorohexanoic acid (PFAS), a chemical linked to potential health risks. The study, testing 22 bands from various brands, found that 15 contained over 1% fluorine, often due to their material—fluoroelastomer or FKM rubber. PFAS, known as “forever chemicals,” may be absorbed through the skin and linked to conditions like reduced fertility, cancer risks, and developmental issues in children.
The study’s lead researcher, Graham Peaslee, notes that while exposure levels are unclear, higher amounts have been associated with health problems. However, consumers should remain cautious due to limited research on PFAS’ effects.
When shopping for smartwatch bands, consider these tips:
1. **Avoid labels** mentioning fluoroelastomer or FKM rubber.
2. **Check materials**: Look for alternatives like silicone, nylon, or leather.
3. **Price point**: Bands under $30 are more likely to be made of fluoropolymer; aim for cheaper options if possible.
Consumers and manufacturers alike are urging brands to reduce PFAS exposure. With ongoing efforts to ban PFOA and PFOS, but many other PFAS remaining, staying informed is key for making safe choices.
