Scientists have tested the level of PFAS in some consumer smartwatch bands They found elevated levels of "forever chemicals" in some models These chemicals are potentially toxic and have been linked to diseases such as cancer Scientists from the University of Notre Dame have called for more comprehensive studies and greater transparency from manufacturers after a study found elevated levels of so-called "forever chemicals" in some consumer smartwatch and fitness tracker bands.

Smartwatches and fitness trackers have become ubiquitous forms of wearable tech, accompanying many people throughout their days (and nights). But they may expose the skin to so-called forever chemicals in the process.

Smartwatches and fitness trackers might pose health risks due to high levels of PFHxA, a chemical found in the fluorinated rubber used in premium wristbands. These findings highlight potential skin exposure concerns from daily wearable tech.

Lead author of the study, Alyssa Wicks, recommends purchasing lower-cost wristbands made from silicone and advises consumers to err on the side of caution.

A study finds significant levels of PFHxA in smartwatch bands, prompting concerns about prolonged skin exposure to these 'forever chemicals.'
