Got a tattoo (permanent or temporary) near your wrists? Then you might not want to buy the Apple Watch. Apple today acknowledged through its official support page that tattoos might interfere with the Apple Watch. The performance of the device is also impacted by skin perfusion.
Citing the reason for inaccurate heart rate readings, Apple said in its support page, “The heart rate sensor in Apple Watch uses what is known as photoplethysmography. This technology, while difficult to pronounce, is based on a very simple fact: Blood is red because it reflects red light and absorbs green light. Apple Watch uses green LED lights paired with light sensitive photodiodes to detect the amount of blood flowing through your wrist at any given moment.”
Tattoo ink might interfere with this technology which basically deals in light. Apple said, “Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings. If you’re not able to get a consistent reading because of any of these factors, you can connect your Apple Watch wirelessly to external heart rate monitors such as Bluetooth chest straps.”
The support page also explains the most appropriate way to wear the device to get best results. It was also noted by several users that dark ink tattoos are likely to interfere more.
