Are There High Amounts of Forever Chemicals in Your Apple Watch Band?

A recent study by the University of Notre Dame sounded the alarm on the existence of high concentrations of “forever chemicals” in smartwatch bands. Forever chemicals, otherwise known as PFAS (per- and poly-fluoroalkyl substances), are synthetic compounds commonly used in consumer products due to their resistance to heat, water, and oil.
These are often used in non-stick cookware, water and stain-resistant fabrics, food packaging, and even cosmetics. These chemicals don’t break down easily and can accumulate over time in your body. PFAS contribute to health problems like cancer, child development issues, liver and kidney damage, and hormone disruption, among others. Here’s what we know so far, along with some tips on minimizing your exposure to forever chemicals.
The study found PFAS at higher levels than other consumer products in 15 of the 22 bands tested. While the study does not specify the exact bands or which brands tested positive, it did note that Apple, Nike, Fitbit, and Google were included. The study concluded there’s a need for more comprehensive exposure studies, given the limited knowledge of how these chemicals are absorbed through the skin. Perhaps surprisingly, bands that tested positive for PFAS often came with a higher price tag.
Interestingly, there’s sometimes a way to tell if a band includes these forever chemicals. The term “fluoroelastomer band” indicates the use of PFAS. For example, Apple’s Ocean Band notes “Fluoroelastomer” in the product’s technical specifications. Fluoroelastomers are the synthetic rubbers we’re talking about. On the other hand, Apple’s “carbon neutral” Trail Loop band does not make the same reference in its specs. However, the study noted that not all bands use PFAS in their marketing materials.
A safer alternative to a fluoroelastomer band would be a silicone band. We’re not saying you should rush out and replace your Apple Watch band, but we do want to help our readers become more conscientious shoppers. Next time you’re in the market for a band, it certainly won’t hurt to intentionally avoid these chemicals. This is especially true if you’re shopping for “sport” bands to wear during your workouts. It’s possible that sweating increases the rate at which PFAS are absorbed through your skin. If you want to take things a step further, use a water filter designed to remove PFAS, use cast iron or stainless steel cookware instead of anything non-stick, and check product labels for PFAS-free certifications.
