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.
There's no real reason to turn off the green lights as they are used to measure heart rate. However, there can be times when the watch is inadvertently taking measurements. For example, if the watch is not being worn but the green lights are on, then it could be a result of a workout still in progress.
