Harmful Chemicals Found In Popular Fitness Bands

A recent study has uncovered alarming risks associated with fitness trackers. According to the University of Notre Dame, many wearable devices are made with per- and polyfluoroalkyl substances (PFAS), toxic chemicals linked to serious health concerns.

Known as “forever chemicals,” PFAS accumulate in the body over time. Their effects include hormonal imbalances, reduced testosterone in men, and developmental issues in children. Experts warn that prolonged skin contact with these chemicals, common with wearable use, allows them to seep into the body.

Pricey fitness trackers may pose the greatest danger. Devices costing more than $15 had the highest PFAS concentrations, with some bands exceeding 1,000 parts per billion.

Parents buying these gadgets for their kids should also beware. Children’s bodies are especially vulnerable, and the extended wear of fitness trackers increases exposure.

Beyond health concerns, wearables collect detailed user data, often shared with third parties. This lack of transparency leaves users vulnerable to data misuse and cyber threats.

While marketed as essential health tools, fitness trackers may carry more risks than benefits.
