Smartwatches and fitness trackers are everywhere, but recent research has raised some red flags about their potential health risks. A study published in Environmental Science & Technology Letters found that some smartwatch wristbands contain high levels of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals.”
The study found that wristbands made from fluorinated synthetic rubber had particularly high levels of PFHxA, a type of PFAS. This chemical is known to stick around in the environment and resist things like water, sweat, and oil. Of the 22 wristbands tested, nine had PFHxA, with some containing more than 16,000 parts per billion (ppb). Interestingly, pricier wristbands (over $30) had higher levels of PFHxA than cheaper ones.
While we don’t fully know how PFHxA affects our health, it’s believed that the chemicals can seep through the skin. PFAS have been linked to serious issues like cancer.
If you’re concerned, experts suggest sticking with silicone bands, which don’t contain PFAS. If you prefer the fancier options, make sure to check the product descriptions carefully to avoid bands made with fluoroelastomers.
This study is a wake-up call for more transparency from manufacturers. As more research is done, it’s crucial for consumers to make informed choices when picking out wearable tech.
