Fitbit CEO James Park doesn't buy into long-term health care concerns over smartwatches and other wearables, despite a recent New York Times story.
The story noted that similar to smartphones, wearables could be linked to cancer, due to radiation being emitted - but Park and others believe this type of research needs to be more carefully examined.
"In general, cell phones are definitely a very different beast than the low powered wearables," Park said in a statement to TIME. "The transmit energies are orders of magnitude higher. So if people are comfortable wearing Bluetooth headsets, I think wearables are even less of a concern because Bluetooth headsets are also close to your head. Wearables are not, unless you happen to sleep right on top of your wrists."
Park also noted that overall health benefits of wearing a fitness tracker outweigh any radio frequency issues.
