Why May You Want to Turn off the Apple Watch Heart Rate and Green Light?
There are a few reasons why you should turn off the green lights or optical heart rate sensor on your Apple Watch:
Firstly, if you notice itching or any redness on your wrist, it’s a good idea to turn off the green lights on your Apple Watch.
Secondly, if you are concerned about the privacy implications of having the optical heart rate sensor constantly monitoring your pulse, you should turn off the green lights on the Apple watch.
Should Green Light Always Be On Apple Watch?

No. Keeping your Apple Watch’s green light always on is unnecessary.
Keeping the green light always on can drain your watch’s battery faster than usual, and it may not provide added benefit unless you perform heart rate monitoring continuously.
Therefore, I don’t recommend you always keep the green lights on your Apple Watch unless you have a specific medical requirement.
Why Does My Apple Watch Light up Green When I’m Not Wearing It?
If your Apple watch series flashes green light when you’re not wearing it, it could be because of an unintentional activation of the HR sensor.
The HR monitor on the Apple watch is the green light to detect the amount of blood that flow in your wrist, which results in measuring your heart rate.
While in some instances, the HR monitor may be accidentally activated when the watch is not worn and placed on a table.
So, to prevent this, turn off your heart rate tracking.
