Smartwatch Straps: The Hidden Danger of Forever Chemicals

Smartwatches have become ubiquitous, a constant presence on our wrists. These sleek, tech-laden bands promise health tracking, communication, and convenience at our fingertips. But a recent study published in Environmental Science & Technology Letters by Notre Dame University reveals a concerning hidden danger lurking within these popular accessories: per- and polyfluoroalkyl substances, or PFAS, often dubbed “forever chemicals.”

In January 2025, researchers tested 22 smartwatch straps from various brands, including Apple, Casetimy, Fitbit, Google, and Samsung. The results were alarming. Fifteen of the tested samples contained elevated levels of Perfluorohexanoic (PFHXA) acid, a type of PFAS.This finding has sparked widespread worry, especially among Apple Watch users. “The most crucial finding of this research is how high the concentration is, only in one PFAS. There are several samples above 1,000 parts per billion of PFHXA which are higher than most PFAS we have seen in consumer products,” explained Graham Peaslee, Professor of Physics and Astronomy at Notre Dame University and one of the study’s authors.

While the researchers haven’t publicly disclosed which specific brands or models contain these harmful chemicals, this revelation has fueled a lawsuit against Apple in the United States brought by consumer representatives. Apple maintains that their Apple Watch products are safe.

But what exactly are these “forever chemicals,” and why are they so dangerous?

PFAS are a large group of man-made chemicals known for their persistence in the environment.As their name suggests, they don’t break down easily and can accumulate in our bodies over time. this accumulation has been linked to serious health problems, including cancer, liver disease, reduced fertility, and weakened immunity.

These “forever chemicals” are found in a surprisingly wide range of everyday products, from non-stick cookware and food packaging to clothing, carpets, fire extinguishers, and even cosmetics. This widespread use means exposure to PFAS can occur through drinking water, consuming contaminated food, or inhaling dust particles containing these chemicals.

The presence of PFAS in smartwatch straps raises serious concerns about the potential risks of prolonged exposure.It highlights the urgent need for greater openness from manufacturers and stricter regulations regarding the use of PFAS in consumer products. As conscious consumers, we need to be aware of these risks and make informed choices about the products we use.

Are PFAS detectable in other types of wearable devices besides smartwatches?

Hidden danger in Everyday Tech: “Forever Chemicals” Found in Smartwatch Straps

Smartwatches are increasingly ubiquitous, worn by millions who rely on them for fitness tracking, notifications, and more. But a recent study published in *Environmental Science & Technology letters* has cast a shadow over these convenient devices, revealing the presence of dangerous “forever chemicals” known as PFAS in a surprising number of smartwatch straps.

These findings have sparked concern among environmental health experts, prompting further inquiry into the potential risks posed by these persistent pollutants.

“The sheer concentration of PFHXA detected in some samples is alarming,” warns Dr. Emily Carter, a leading environmental toxicologist. “These levels exceed what we’ve typically seen in other consumer products.Smartwatches are worn directly against our skin, increasing the potential for absorption of these harmful chemicals.”

Dr. carter explains that PFAS, short for perfluoroalkyl and polyfluoroalkyl substances, are incredibly persistent in the environment. “They don’t break down easily, earning them the nickname ‘forever chemicals.’ Over time, they accumulate in our bodies and have been linked to serious health problems including cancer, liver disease, reduced fertility, and weakened immunity.”

What makes the finding in smartwatch straps particularly concerning is the direct contact these straps have with our skin. This raises the possibility of increased absorption of these harmful chemicals.

So, what can consumers do to protect themselves?

“Awareness is key,” Dr. Carter emphasizes. “Consumers should educate themselves about PFAS, read product labels carefully, and choose products made with safer alternatives. Supporting stricter regulations on PFAS use in consumer goods is also crucial.”

Dr. Carter also suggests that smartwatch users consider limiting their exposure by choosing option materials for their straps, wearing gloves, or regularly cleaning their straps.

This alarming discovery underscores the importance of scrutinizing everyday products for hidden dangers. As Dr. Carter puts it, “Manufacturers have a responsibility to prioritize consumer safety. They must prioritize research, transparency, and the development of safer alternatives.”

An Interview with Dr. Emily Carter, Environmental Toxicologist

Smartwatches have become more than just timepieces, evolving into essential tools for health tracking, dialogue, and daily life.However, a recent study published in *Environmental Science & Technology Letters* has revealed a concerning presence of harmful “forever chemicals” known as PFAS in a range of smartwatch straps. We spoke to Dr. Emily Carter, a leading environmental toxicologist, to gain further insights into this alarming discovery.

What exactly are PFAS, and why are they considered so hazardous?

PFAS stands for per- and polyfluoroalkyl substances.They’re a large group of man-made chemicals that have been used in countless products since the 1940s. Their unique chemical structure makes them highly resistant to degradation, earning them the nickname “forever chemicals.” As they don’t break down in the environment or our bodies, they accumulate over time, leading to potential health issues.

How have PFAS been detected in smartwatch straps? research

Recent studies have identified elevated levels of PFHXA, a specific type of PFAS, in a number of smartwatch straps from various brands. The presence of these chemicals raises serious concerns, especially given that smartwatches are often worn directly against the skin.

What are the potential health risks associated with prolonged exposure to PFAS through smartwatch straps?

PFAS have been linked to a range of adverse health effects, including cancer, liver disease, immune system suppression, reduced fertility, and developmental problems. The danger lies in the accumulation of these chemicals in our bodies over time. The amount of exposure from a smartwatch strap may seem small,but it’s significant to remember that we are exposed to PFAS through multiple sources in our daily lives.

What steps can consumers take to minimize their exposure to PFAS from smartwatch straps?

awareness is key. Purchase smartwatches with straps made from safer materials, such as silicone or leather, and prioritize brands that are obvious about their manufacturing processes. Regularly cleaning your smartwatch strap can also help reduce exposure. Consider wearing gloves while using your smartwatch, especially when handling food or cleaning substances that might contain PFAS.

What needs to be done to address this issue on a larger scale?

Manufacturers need to prioritize consumer safety by phasing out PFAS from their products and investing in research and advancement of safer alternatives. Government agencies must implement stricter regulations regarding the use of PFAS in consumer goods. Public awareness campaigns can definitely help educate consumers about the risks associated with PFAS and empower them to make informed choices.

The presence of PFAS in smartwatch straps highlights the critical need for greater transparency and duty from manufacturers. It underscores the importance of continuous research and stricter regulations to protect consumers from these harmful chemicals.
