Some Apple Watch bands pose a risk to your health

Connected watch bracelets are part of our daily lives. We wear them on our wrists all day, sometimes even at night. But did you know that some of these bracelets could contain substances harmful to your health ? This is what a study published in the journal Environmental Science & Technology Letters reveals.

Researchers from the University of Notre Dame analyzed 22 different bracelets brands and price ranges. The results are disturbing: several bracelets, including those of Apple Watches, contain high levels of perfluorohexanoic acid (PFHxA). This compound is part of the PFAS family, also known as “perennial pollutants”.

Alarming levels of PFHxA in premium bracelets

The study shows that high-end bracelets, often made from fluoroelastomer, are the most affected. Nine of the 22 bracelets tested contained PFHxA, with a median concentration of 800 parts per billion (ppb). One sample even exceeded 16,000 ppb!

For comparison, a previous study found PFAS levels around 200 ppb in cosmetics. Researchers had never observed such concentrations in products worn directly on the skin.

What are the health risks?

PFHxA is part of PFAS, a group of chemical compounds used in industry since the 1940s. Their almost indestructible molecular structure earned them the nickname “eternal pollutants”. Once released into the environment, they degrade very slowly and can accumulate in living organisms.

Several studies have linked exposure to PFAS to various health problems such as cancer, diabetes, obesity and even reproductive disorders. While the precise effects of PFHxA remain to be determined, experts agree on the need to limit our exposure to these substances.

What should you do if you have an affected bracelet?

If you own an Apple Watch or another smartwatch with a fluoroelastomer strap, don’t panic. The scientists point out that it is unlikely that a significant amount of PFHxA is absorbed through the skin.

However, it always seems good to be aware of our cumulative exposure to these pollutants. If you wish change braceletopt for materials like silicone, metal or fabric. You can also find a selection of premium Apple Watch bracelets by following this link.
