Jakarta, Indonesia Sentinel — A recent study in the United States has found that smartwatch bands contain high levels of toxic chemicals polyfluoroalkyl substances (PFAS), which can be absorbed through the skin and pose significant health risks, including cancer.
As smartwatch and fitness trackers grow in popularity among health-conscious consumers, researchers warn that the bands may be a major source toxic chemicals exposure. The study, conducted by Notre Dame University, analyzed bands from 22 common smartwatch brands and found that 15 of them contained dangerously high levels of PFAS.
“These findings are highly concerning because smartwatch bands are worn directly on the skin for long periods,” said Graham Peaslee, one of the study’s authors, as reported by The Guardian. “The levels detected in the bands were much higher than most PFAS we have seen in consumer products.”
While the exact mechanism of PFAS absorption through the skin remains unclear, previous studies have shown that these chemicals can be absorbed dermally.
Waterproof Agents
PFAS are commonly used in consumer products, such as rain gear and hiking equipment, as waterproofing agents. “These chemicals are likely added to synthetic rubber bands to prevent sweat stains and dirt buildup over time,” Peaslee explained.
The study did not disclose specific brands tested but noted that some manufacturers provided information on the presence of PFAS in their products, while others did not. Researchers suggested that silicone smartwatch bands may be a safer alternative.
PFAS Dangers
According to the U.S. Centers for Disease Control and Prevention (CDC), PFAS are a group of thousands of synthetic chemicals used to make products resistant to water, stains, and heat. Often referred to as “forever chemicals,” PFAS do not break down naturally and accumulate in the environment over time.
Medical research has linked PFAS exposure to serious health issues, including cancer, kidney and liver problems, immune system disorders, birth defects, and other severe conditions.

Given the potential health risks associated with PFAS exposure, experts recommend consumers be more mindful of the materials used in wearable devices. Choosing alternative wristband materials, such as silicone, and staying informed about product safety can help minimize exposure to these harmful chemicals.
