Toxic Timepieces: High Levels of Forever Chemicals Found in Smartwatch Bands
Your smartwatch or fitness tracker might be more than just a health companion—it could be a source of harmful chemicals. Recent research has revealed that bands used for these devices contain synthetic rubber made with PFAS, also known as “forever chemicals”, which might potentially be absorbed into the skin.
A study conducted by researchers from the University of Notre Dame tested 22 bands from various price points commonly available in the U.S. The findings, published in Environmental science and Technology, showed that the most expensive bands—those retailing for more than $15—contained the highest concentrations of these chemicals.
“The most remarkable thing we found in this study was the very high concentrations of just one PFAS—there were some samples above 1,000 parts per billion of PFHxA, which is much higher than most PFAS we have seen in consumer products,” said Graham peaslee, co-author of the study and professor emeritus in the Department of Physics and Astronomy, in a statement from the university.
What Are PFAS?
PFAS (Per- and polyfluoroalkyl substances) are a group of synthetic chemicals known for their water and oil-repelling properties. They are often used in consumer products for their durability and resistance to discoloration and dirt.However,their environmental persistence and potential health risks have raised notable concerns.
The Risks of PFAS in Wearable Devices
Smartwatches and fitness trackers are worn for extended periods, often during exercise when the skin is more absorbent. this increases the likelihood of PFAS penetrating the skin and entering the bloodstream. A 2024 study confirmed that some PFAS can indeed pass through the skin, raising red flags for daily users of these devices.
Key Findings from the Study
| Key Insight | Details |
|————————————-|—————————————————————————–|
| Highest PFAS Concentrations | Found in bands retailing for more than $15 |
| PFHxA Levels | some samples exceeded 1,000 parts per billion |
| Absorption Risk | PFAS can penetrate the skin and enter the bloodstream |
What This Means for Consumers
The presence of PFAS in smartwatch bands highlights a growing public health concern. These chemicals are toxic at extremely low levels, and their widespread use in consumer products has led to calls for stricter regulations.
As the demand for wearable technology continues to rise, so does the need for safer materials. Consumers are encouraged to stay informed and consider the potential risks associated with the products they use daily.

High fluorine concentrations indicate the presence of PFAS, a group of chemicals linked to serious health concerns.Earlier research, as reported by the Guardian, suggests that up to 60% of PFAS may be topically absorbed into the skin, with sweat potentially increasing the absorption rate. This is notably alarming since these devices are designed to be worn during exercise.As Wicks noted,there can be “significant transfer through the skin.”
The National Institute of Environmental Health Sciences highlights that “multiple health effects associated with PFAS exposure have been identified,” including an increased risk of cancer, childhood obesity, metabolism disruption, and immune system impairment.| Key Findings | Details |

Toxic Timepieces: High Levels of Forever Chemicals Found in Smartwatch Bands
Your smartwatch or fitness tracker might be more than just a health companion—it could be a source of harmful chemicals. Recent research has revealed that bands used for thes devices contain synthetic rubber made with PFAS, also known as “forever chemicals”, which might possibly be absorbed into the skin. To better understand the implications of this study, Senior Editor of world-today-news.com, Sarah Mitchell, sat down with Dr. Emily Carter, a renowned environmental chemist and expert on PFAS, to discuss the findings and their meaning for consumers.
Understanding PFAS: What Are They and Why Are They Concerning?
Sarah Mitchell: Dr. carter, could you start by explaining what PFAS are and why they’ve become such a hot topic in environmental and health discussions?
Dr.Emily Carter: Absolutely, Sarah. PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals known for their water- and oil-repelling properties. They’re ofen used in consumer products like non-stick cookware, waterproof clothing, and, as we now know, smartwatch bands. The concern lies in their persistence—they don’t break down easily in the environment or the human body, earning them the nickname “forever chemicals.” They’ve been linked to serious health issues, including cancer, immune system disruption, and metabolic disorders.
The Study’s Findings: PFAS in Smartwatch Bands
Sarah Mitchell: A recent study by the University of Notre Dame found high levels of PFAS in smartwatch bands. What were the key takeaways from this research?
Dr. emily Carter: The study tested 22 smartwatch bands and found that 15 of them contained high levels of total fluorine, indicating the presence of PFAS.Nine of these bands specifically contained PFHxA, a type of PFAS, at concentrations exceeding 1,000 parts per billion in certain specific cases. What’s particularly alarming is that these chemicals were found in bands retailing for more than $15, suggesting that even higher-end products may not be free of these toxins. The study also highlighted the potential for PFAS to penetrate the skin, especially during exercise when the skin is more absorbent.
The Risks of PFAS in wearable Devices
Sarah Mitchell: Why are wearable devices like smartwatches particularly concerning when it comes to PFAS exposure?
Dr. Emily Carter: Wearable devices are designed to be worn for extended periods, frequently enough during physical activities where the skin is more permeable due to sweat.This increases the likelihood of PFAS being absorbed into the bloodstream. Earlier research suggests that up to 60% of PFAS can be absorbed through the skin,and sweat may accelerate this process. Given that these devices are in direct contact with the skin for hours each day, the potential for chronic exposure is important.
Health Implications and Regulatory Concerns
Sarah Mitchell: What are the potential health risks associated with PFAS exposure, and should consumers be worried about their smartwatch bands?
dr. Emily Carter: The health risks are serious and well-documented. PFAS exposure has been linked to an increased risk of cancer, childhood obesity, metabolic disorders, and immune system dysfunction. these chemicals are toxic even at extremely low levels, which is why their presence in consumer products is so concerning. While more research is needed to fully understand the extent of PFAS absorption from smartwatch bands, the findings certainly warrant caution. This also highlights the need for stricter regulations and safer materials in the manufacturing of wearable technology.
What Can Consumers Do?
Sarah Mitchell: What steps can consumers take to protect themselves from PFAS exposure in wearable devices?
Dr. Emily Carter: First and foremost, consumers should stay informed. Look for brands that are transparent about the materials they use and avoid products with fluoroelastomers,which are a common source of PFAS in smartwatch bands. Consider replacing bands with those made from natural materials like leather or silicone, which are less likely to contain these chemicals. Additionally, advocating for stronger regulations and supporting research into safer alternatives can help drive industry change.
Looking Ahead: The Future of Wearable Technology
sarah Mitchell: What does this study mean for the future of wearable technology and consumer safety?
Dr. Emily Carter: This study serves as a wake-up call for both manufacturers and consumers. As the demand for wearable technology continues to grow, so does the responsibility to ensure these products are safe. I hope this research will encourage companies to prioritize the use of non-toxic materials and invest in safer alternatives.For consumers, it’s a reminder to be mindful of the products we use and their potential health impacts.Informed choices and advocacy can drive positive change in the industry.
