Study Reveals Harmful 'Forever Chemicals' in Smartwatch Bands

Researchers found high levels of PFHxA in fluoroelastomer wristbands, raising concerns about prolonged skin exposure and potential health risks.

A study tested 22 smartwatch bands and found significant levels of PFHxA, a type of PFAS known as 'forever chemicals,' in nine bands.
Fluoroelastomer bands, often marketed as durable and sweat-resistant, were identified as the primary source of these chemicals.
Higher-priced bands (over $30) were more likely to contain PFHxA, with concentrations reaching up to 16,000 parts per billion in some cases.
Researchers warn that prolonged contact, such as wearing these bands for over 11 hours daily, may increase skin absorption of PFHxA.
Consumers are advised to avoid fluoroelastomer bands and opt for lower-cost silicone alternatives to reduce exposure risks.
