Expensive Smartwatch Wristbands Can Cause Skin Problems: Study

A recent study published in *Environmental Science & Technology Letters* reveals that smartwatch and fitness tracker wristbands may contain high levels of “forever chemicals,” specifically perfluorohexanoic acid (PFHxA). Researchers found that expensive wristbands made from fluorinated synthetic rubber exhibited particularly high concentrations of PFHxA, raising concerns about skin exposure.
