Dangerous fitness bracelets: study discovers harmful chemicals!

A current study from the USA warns of the health risks of bracelets for smartwatches and fitness trackers. Researchers from the University of Notre Dame have found that 9 out of 22 devices tested have increased values ​​of so-called PFAs (per- and polyfluorinated alkyl substances). These long -lasting chemicals are difficult to break down and have been used in numerous products for decades. The study reveals that the concentrations of these chemicals are over 1000 parts per billion-an alarming number that is far above the usual values ​​in consumer materials, such as reported.

PFAS were associated with a variety of health problems, including hormonal disorders, developmental delays in children and an increased risk of cancer. The fact that more expensive ligaments, such as the Apple or Fitbit, tend to have higher PFAS values ​​are particularly worrying. While the study examined only about 20 of over 14,000 known PFAS types, the researchers emphasize the need for further studies in order to gain extensive knowledge. A parallel examination for portable technologies shows that a variety of sensors, including photoplethysmography for heart rate measurement, is installed in the latest fitness trackers. This development represents new challenges for data collection in the health sector and raises questions about the security and effectiveness of these devices, such as PMC explained in detail.

Overall, both studies illustrate the need to critically question which technologies we use in our daily life, especially when it comes to our health. The connection between modern wearables and health risks is a topic that cannot be ignored.
