To what green light are you referring?

Hi


The green LEDs are used by the heart rate sensor. It is normal for the sensor to take background measurements of your heart rate regularly throughout the day, but the LEDs do not remain permanently lit for this purpose.


It should not typically be possible to see the LEDs. For the best performance from your Apple Watch, check that you are wearing your watch sufficiently snugly on the top of your wrist:

If the LEDs are permanently lit, you may have a workout or other fitness-based session in progress (there may also be a runner icon on your watch face).


In the Workout app - and also any third-party fitness tracking app that you may have installed - be sure to end any workout that is currently paused or in progress:



If the icon remains / the LEDs remain lit up after ending any active workout, restart your watch:
