A new study reveals alarming levels of per- and polyfluoroalkyl substances (PFAS) in popular fitness tracker and smartwatch bands, raising concerns about potential health risks.
A recent study conducted by researchers at the University of Notre Dame has revealed alarming levels of a harmful man-made chemical in several popular fitness tracker and smartwatch bands . The study analyzed 22 wristbands across various price ranges and discovered that many contained high concentrations of perfluorohexanoic acid (PFHxA), a type of per- and polyfluoroalkyl substance ( PFAS ). PFAS are often referred to as “ forever chemicals ” due to their exceptional persistence in the environment.
They do not readily break down and can remain in soil and groundwater for extended periods. The presence of PFHxA in these wristbands raises serious concerns about potential health risks. PFAS have been linked to a variety of adverse health effects in humans, including reduced immune function, elevated cholesterol, thyroid dysfunction, liver damage, developmental delays in children, and an increased risk of certain cancers, particularly kidney and testicular cancers.The study authors emphasized the significance of their findings, noting the unusually high concentrations of PFHxA detected in some of the wristbands. They pointed out that these levels far exceeded those typically found in other consumer products. Furthermore, the researchers acknowledged the limited existing research on the dermal absorption of PFAS. While a previous European study indicated that certain types of PFAS could transfer through the skin, more investigations are needed to fully understand the extent to which PFAS can be absorbed through the skin during regular use of wristbands. The study recommended further research to assess the potential risks associated with PFAS exposure from these devices
