Smartwatch and Fitness Tracker Bands Contain Harmful Chemicals
New Study Reveals High Concentrations of PFAS in Popular Wearable Technology
A new study finds that several brands of fitness tracker and smartwatch bands contain “very high concentrations” of a man-made chemical that can harm our health.
High Levels of PFHxA Found in Nine Bands
Nine of the 22 wristbands tested had elevated levels of perfluorohexanoic acid (PFHxA), a type of per- and polyfluoroalkyl substances (PFAS). These compounds are known as “forever chemicals” — and they’ve been linked to a host of health problems, including an increased risk of certain cancers.
“The most remarkable thing we found in this study was the very high concentrations of just one PFAS — there were some samples above 1,000 parts per billion of PFHxA, which is much higher than most PFAS we have seen in consumer products,” said Graham Peaslee, study co-author and professor emeritus in the Department of Physics and Astronomy.
PFAS Linked to Health Issues
PFAS have been detected in fast food containers, non-stick cookware, stain- and water-resistant fabrics, shampoo, cosmetics, paints, and adhesives, among other products. Exposure to high doses of PFHxA may harm the liver, thyroid, red blood cell count, and the developing fetus.
Most Watchbands Contained High Fluorine Levels
Three of the bands included in the analysis were deemed expensive because they cost over $30 — all three contained considerably high amounts of fluorine. Elevated fluorine levels are a strong indicator of PFAS contamination, the researchers said, because all PFAS molecules contain fluorine atoms.
Call for Further Research
Peaslee said the results warrant a more comprehensive study on PFAS in watchbands. “Few studies so far have been published regarding the dermal absorption of PFAS,” said Alyssa Wicks, a graduate student in Peaslee’s lab and lead study author.
Conclusion
The findings of this study highlight the need for further research on the potential health risks associated with the use of PFAS-containing watchbands. As wearable technology becomes increasingly popular, it is essential that manufacturers prioritize the safety and well-being of their customers by exploring alternative materials and production methods.
FAQs
What are PFAS? PFAS are a class of synthetic chemicals that have been linked to various health problems, including an increased risk of certain cancers.
What is PFHxA? PFHxA is a type of PFAS that has been detected in a range of consumer products, including fast food containers, non-stick cookware, and stain- and water-resistant fabrics.
How do PFAS enter the body? PFAS can enter the body through dermal absorption, inhalation, or ingestion. In the case of watchbands, PFAS can be absorbed through the skin.
What are the potential health effects of PFAS exposure? Exposure to PFAS has been linked to a range of health problems, including reduced immune function, elevated cholesterol, thyroid dysfunction, liver damage, developmental delays in children, and an increased risk of certain cancers.
