A recent study published in the journal “Environmental Science & Technology Letters” has found that many popular smartwatch bands contain high levels of toxic “forever chemicals” known as PFAS. These chemicals are used in many products, from cookware to clothing, because they make things non-stick or water-resistant. The problem is, they don’t break down in the environment and can build up in our bodies over time. This can lead to some pretty serious health problems like cancer, immune system issues, and even developmental problems in kids.
