<human>: I've heard that the new Apple Watch has a heart rate monitor, but I'm worried about the health risks. What are the potential risks?
<bot>: The potential risks of using a heart rate monitor include skin irritation from wearing the device and an increased risk of overheating or dehydration if the user is not careful. Additionally, some people may be more sensitive to electromagnetic radiation emitted by the watch, which can cause headaches and other symptoms. Finally, there is always the possibility of false readings due to motion artifacts.
