You probably wear your smartwatch every day.
Most people do.
But there are a couple of things worth knowing.
That watch sits directly on your skin for hours.
While it is on, it sends out radiofrequency signals.
These signals are classified as possibly carcinogenic by the World Health Organization.
The closer the device is to your body, the higher the exposure.
Then there is the strap.
Recent testing found that many popular smartwatch bands contain PFAS, often called forever chemicals.
These chemicals are linked to hormone disruption, liver stress, and long term health problems.
The skin on your wrist is thin.
PFAS can pass through the skin.
They build up in the body and do not break down easily.
This is not about panic.
It is about awareness.
Simple things that can help:
• Take the watch off when you do not need it
• Avoid wearing it all day or while sleeping
• Switch to a PFAS free strap made from natural materials
Small changes like this can reduce daily exposure.
Over time, that matters.
