Health Risks Linked To Popular Smartwatches

Fitness trackers and smartwatches, worn by millions, may come with hidden dangers. A recent study by the University of Notre Dame found that many bands contain high levels of harmful PFAS chemicals.

PFAS, also called “forever chemicals,” are nearly impossible to break down. These substances have been associated with health issues like hormonal imbalance, cancer, and developmental problems in children. Continuous skin contact with these bands allows PFAS to transfer into the body, particularly during exercise when sweat and warmth facilitate absorption.

Expensive brands tend to have the highest PFAS levels, with some bands exceeding 1,000 parts per billion. For context, PFAS levels in drinking water are flagged as unsafe at just four parts per trillion.

The issue is even more concerning for children, who are increasingly using these devices. Prolonged exposure may interfere with growth and puberty, as developing bodies are more sensitive to chemical risks.

Data collection by these devices adds another layer of concern. Many trackers share user information with third parties, and researchers have identified vulnerabilities in GPS-enabled wearables that expose children to exploitation.

Studies suggest that lower-cost options are less toxic, though no device is entirely free of PFAS.
