Are Your Fitness Trackers Secretly harming Your health?
Fitness trackers and smartwatches have become ubiquitous, offering a wealth of data about our activity levels, sleep patterns, and even heart rate variability.But a recent study has raised serious concerns about the potential health risks associated with these popular devices.
Researchers at the University of Notre Dame discovered that many fitness tracker and smartwatch bands contain high levels of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals.” These chemicals, used to make products water-resistant and stain-resistant, have been linked to a range of health problems, including cancer, liver disease, immune disorders, and developmental issues in children.
The study,published in Environmental Science Letters,found PFAS in 15 out of 22 common fitness tracker and smartwatch bands tested. The levels detected were significantly higher than those typically found in other consumer products.
“The levels detected in the bands were much higher than most PFAS we have seen in consumer products,” said Graham Peaslee,a Notre Dame researcher and co-author of the study.
Why are runners at particular risk?
runners are especially vulnerable to PFAS exposure because sweat can increase the rate at which these chemicals are absorbed through the skin. Since fitness trackers are worn tightly against the skin for prolonged periods, this could mean continuous exposure to harmful PFAS.
“Previous research has shown that up to 60% of certain PFAS in skin-applied products can be absorbed,” Peaslee explained. “The fact that these bands are worn so close to the skin for extended periods raises concerns about the potential for important PFAS absorption.”
The long-term health implications are concerning.
The persistent nature of PFAS means they accumulate in the body over time. This raises serious long-term health concerns, especially for athletes who wear their trackers regularly.
“the exact rate at which these chemicals are absorbed remains unclear,” Peaslee said. “But their persistent nature means they accumulate in the body over time, raising long-term health concerns.”
What can runners do to protect themselves?
The good news is that there are steps runners can take to minimize their exposure to PFAS.
Choose silicone bands: silicone bands are a safer alternative to fluoroelastomer bands, which often contain PFAS.
Research your brands: Some brands openly advertise their use of fluoroelastomer bands, while others are less transparent.Do your research before you buy. Consider the price: Interestingly, Peaslee noted that bands containing PFAS were frequently enough priced higher than those without. This could be a clue to look out for.
Don’t panic, but be informed: “I don’t need someone to rush to throw away their Christmas gifts,” Peaslee advised. “But next time you buy one, move away from those with PFAS.”
The bottom line:
Fitness trackers and smartwatches can be valuable tools for runners, but it’s critically important to be aware of the potential risks associated with PFAS. By making informed choices about the bands you use, you can enjoy the benefits of wearable technology while minimizing your exposure to these harmful chemicals.
Are Your fitness Trackers Secretly Harming Your Health? A Q&A With Environmental Scientist graham Peaslee
Time.news: Recent research has uncovered a potential health risk linked to fitness trackers – the presence of “forever chemicals” known as PFAS in many bands.Can you shed some light on this alarming discovery and its implications for runners?
Graham Peaslee: It’s true. My team at the University of Notre Dame found concerning levels of PFAS in a significant number of common fitness tracker and smartwatch bands we tested. These “forever chemicals” are known to persist in the environment and the human body, and have been associated with various health problems, including cancer, liver disease, and immune system issues.
Time.news: That’s concerning. What makes runners particularly vulnerable to these chemicals?
Graham Peaslee: Runners are exposed to these chemicals through their sweat. Research suggests that up to 60% of certain PFAS in skin-applied products can be absorbed through the skin. Given that fitness trackers are worn tightly against the skin during prolonged exercise, this continuous exposure raises significant concerns about PFAS absorption levels for runners.
Time.news: What are the long-term health implications of this kind of exposure?
Graham Peaslee: The long-term effects remain unclear, but the persistence of PFAS is what’s most alarming. They accumulate in the body over time. This means that even low-level exposures, such as those potentially occurring through fitness tracker bands, could substantially impact health in the long run.
Time.news: So, what should runners do? Is it time to ditch their trackers entirely?
Graham Peaslee: Absolutely not! Fitness trackers can be valuable tools. My advice is to be informed and make smart choices.
Time.news: What steps can runners take to minimize their risk?
Graham Peaslee: Firstly, look for silicone bands. They tend to be a safer alternative to fluoroelastomer bands, which are more likely to contain PFAS. Second, research your brands. Some are transparent about their use of PFAS, while others are not. Don’t hesitate to reach out to manufacturers directly to inquire about the materials used in their products.
Interestingly, we observed that bands containing PFAS were often priced higher. This could be a clue to look out for. don’t panic, but do be aware. When making your next purchase, opt for bands that are PFAS-free.
Time.news: Thank you, Dr. Peaslee. This is a crucial topic for runners and anyone who uses wearable technology. Your advice is timely and informative.
Graham Peaslee: It’s my pleasure. I encourage everyone to be proactive about their health and make informed choices about the products they use.
