A recent study has revealed that popular smartwatch bands, especially those made from fluoroelastomers, contain high levels of PFAS (per- and polyfluoroalkyl substances), commonly known as forever chemicals.
These toxic substances are known for their persistence in the environment and the human body, accumulating over time and causing potential health risks.
What Are Forever Chemicals?
PFAS are synthetic chemicals used in a wide range of consumer products, including non-stick cookware, water-resistant clothing, carpets, and even food packaging.
They are notorious for their inability to break down in nature, leading to their nickname, “forever chemicals.”
Exposure to PFAS has been linked to several health issues, including an increased risk of cancer, hormone disruption, weakened immune systems, and developmental delays in children.
Shocking Findings in Smartwatch Bands
The study, published in Environmental Science & Technology Letters, focused on 22 smartwatch bands across different brands and price points.
Researchers found that these bands, particularly those marketed for sports and fitness, contained high concentrations of PFHxA, a type of PFAS.
The chemicals can easily be absorbed into the skin, especially during physical activities like exercise, when sweat and open pores can increase absorption.
Health Risks and Concerns
The study’s lead author, Graham F. Peaslee, a physicist at the University of Notre Dame, expressed surprise at the high levels of PFHxA found in the bands.
The researchers initially didn’t set out to investigate PFAS in smartwatch bands, but upon discovering the chemical, they were alarmed by its concentration, which was much higher than typically found in consumer products.
The full health risks of prolonged exposure to these chemicals through smartwatch bands are still under investigation.
However, experts are concerned about the potential long-term effects of skin contact with such high levels of PFAS, particularly for individuals who wear these bands during physical activities.
What Can Consumers Do?
Given the potential risks, experts recommend that users avoid smartwatch bands made from fluoroelastomers and opt for safer alternatives.
Many brands disclose the materials used in their bands, so consumers can check product details before making a purchase.
However, fluoroelastomer bands are popular for their water and sweat resistance, which may make them a preferred choice for some users, creating a challenge for those who prioritize durability.
In the meantime, further research into the health implications of PFAS in consumer products is needed to better understand the risks and guide safer alternatives.
