Imagine finishing a workout, sweat soaking into your watch band—unaware that the soft strap clinging to your skin may quietly release tiny amounts of “forever chemicals” into your body. A new class action lawsuit claims that some Apple Watch wristbands contain dangerous levels of PFAS, or “forever chemicals.” These man-made substances are found in items like nonstick cookware, waterproof clothing, and drinking water. PFAS have been linked to health problems such as cancer, pregnancy complications, and possible mental health issues like anxiety and depression.
The Allegations Against Apple
The lawsuit, filed in the United States District Court for the Northern District of California, claims that three Apple Watch bands—the Sport Band, Ocean Band, and Nike Sport Band—contain high levels of PFAS to enhance durability and resistance to sweat and skin oils. According to the lawsuit, tests cited from a recent University of Notre Dame study found that some Apple Watch bands contained up to 250 micrograms of extractable organic fluorine per gram of material. For context, 1 microgram per gram is equal to 1 part per million (ppm), so 250 micrograms per gram amounts to 250 ppm of fluorine. This is far above the 100 ppm screening threshold for fluorine that is often used to flag potential PFAS contamination in consumer products.
For comparison, typical background levels of PFAS in everyday objects or the environment can be much lower, sometimes under 10 ppm, although these numbers vary depending on the product and regulations in different regions.
However, there are currently no standardized legal limits on PFAS in wearable products like watch bands—regulations mainly focus on PFAS levels in drinking water or food packaging. By naming these specific numbers, the lawsuit argues that the levels present in Apple Watch bands are not only elevated but could rise to the level of regulatory or legal concern, raising questions about the safety of prolonged skin exposure.
The complaint says Apple knew about the possible risks but chose not to use safer materials like silicone to save money. It also claims Apple misled customers by promoting the Apple Watch as a health product without revealing the use of harmful chemicals.
New Study Raises Concerns About PFAS in Watch Bands
A December 2024 study analyzed 22 smartwatch bands from multiple brands and found that 15 contained more than 1% fluorine, indicating the widespread use of fluoroelastomers—synthetic rubbers that are a polymeric form of PFAS. Researchers also detected perfluorohexanoic acid (PFHxA), a type of PFAS, in some bands.
According to the study, “The very high concentrations of PFHxA readily extractable from the surfaces of fluoroelastomer watch bands, together with the current limited knowledge on the dermal absorption of PFHxA, demonstrate the need for more comprehensive exposure studies.”
This shows that scientists do not yet know how much of these chemicals can actually get through your skin when you wear a watch band all day. There is still a lot we do not know about whether, or how much, these chemicals are absorbed with everyday use. In the meantime, if you want to be cautious while research continues, you can take practical steps to minimize potential risks.
For example, try rotating between different bands rather than wearing the same one constantly, wash your bands regularly according to the manufacturer’s instructions, and make sure your skin is clean and dry before putting on your watch. Taking these small precautions may help reduce your exposure until more is known.
The Link Between Forever Chemicals and Mental Health
PFAS are mostly known for their effects on physical health, but new research is starting to show they may also affect the brain. Some studies suggest that PFAS exposure could play a role in anxiety, depression, and problems with thinking by disrupting hormones and brain chemicals.
What does ‘suggest’ really mean in scientific terms? When researchers say that PFAS exposure is ‘linked’ to mental health symptoms, it means they have noticed a relationship between the two, but this does not prove that PFAS actually cause these changes. In science, correlation does not always mean causation. More studies are needed to find out if PFAS directly cause mental health issues, or if other factors are also involved.
- Endocrine Disruption: PFAS can change hormone levels, especially cortisol and thyroid hormones, which are important for mood and handling stress.
- Neuroinflammation: Some studies suggest that PFAS exposure triggers inflammation in the brain, which has been linked to mood disorders and creates a persistent mental cloud—like a low-grade brain haze—that can make it harder to think clearly, focus, and remember things.
- Sleep Disruptions: PFAS chemicals have been linked to poor sleep, which can make anxiety and depression worse.
For people who already have mental health issues, long-term exposure to these chemicals may make symptoms worse. This makes it even more important to avoid products that contain PFAS.
How Much PFAS Exposure Happens Through the Skin?
While the presence of PFAS in watch bands is concerning, there is still limited research on how much, if any, of these chemicals are absorbed through the skin from wearable devices. The December 2024 study underscores this uncertainty, noting that although high levels of PFAS were detected in watch bands, further research is needed to determine whether prolonged skin contact results in significant absorption.
Because of the possible health risks, some people may want to reduce their exposure by choosing bands made from other materials.
What the Lawsuit Claims vs What We Know Scientifically
Lawsuits alleging harm from chemicals in Apple Watch bands focus on claims that some materials contain PFAS or similar substances. It is important to separate these legal claims from what science currently shows. While lawsuits mention possible exposures, research is still underway to find out what levels, if any, are actually risky in daily use.r Consumers
The lawsuit asks for refunds for people who may have paid too much for bands because of misleading ads. It also wants Apple to stop selling these products unless they clearly state what chemicals are in them.
The study also examined bands from other smartwatch brands, including Fitbit and Samsung, though the specific findings remain unclear.
However, the lawsuit highlights Google’s Pixel Watch Woven Band (made from recycled yarn) and Fitbit’s Sport Band (made from silicone) as potentially PFAS-free alternatives. If you want to choose a safer watch band, look for ones made from materials less likely to contain PFAS, such as silicone, leather, or fabric.
To verify that a band is truly PFAS-free, check product packaging and descriptions for statements like “PFAS-free” or “fluoroelastomer-free,” and look for certifications such as OEKO-TEX or Bluesign, which indicate restrictions on harmful chemicals. You can also contact manufacturers directly to ask if their products contain any fluorinated compounds. Taking these steps can help you make more informed and safer choices when it comes to wearable tech.
What This Means for Consumers
Protecting Your Mental and Physical Health
If you are worried about the possible effects of PFAS, here are some steps you can take:
Next time you are shopping for a watch band, try asking questions like: “Does this band contain any fluorinated compounds?” or “Can you confirm if this watch band is PFAS-free?”
You might also say, “I’d like to know if your bands contain any chemicals like PFAS or fluoroelastomers.”
Bringing these questions up not only helps you make a more informed choice, but also encourages companies and retailers to be more transparent about what goes into their products.
For example, if you are talking to a sales associate or reaching out by email, you could use a script like: “Hello, I’m interested in purchasing a watch band and I’m concerned about the potential presence of PFAS or other fluorinated chemicals. Could you please tell me if this product is free of those substances?”
✅ Switch to safer alternatives: Bands made from silicone, leather, or natural fabrics may help lower your exposure.
✅ Advocate for transparency: Ask for clearer labels and stronger rules to help keep consumers safe.
For now, if you are concerned about how PFAS exposure could affect your health, especially your mental well-being, choosing a third-party silicone or fabric band may be a safer option. Your wrist, your choice, your voice in shaping safer tech.
Frequently Asked Questions: Apple Watch Lawsuit & Forever Chemicals
