How to turn off green light on Apple Watch

Although Apple Watch is the finest wearable for iPhone users, it might take some time to get used to everything it has to offer. Users are often unaware of the bright green lights that often illuminate the Apple Watch’s back. In this post, I’ll explain what that green light indicates and how you can turn it off on your Apple Watch.

What is green light on Apple Watch?

Your Apple Watch’s green light is an optical heart sensor that indicates your heart rate. Apple did this with the help of the green light because blood is an excellent absorber of this particular color. 

They combined the green LED lights with light-sensitive photodiodes, which can measure how much blood is flowing through the wrist. When wearing your Apple Watch properly, it releases green light that passes through the wrist hundreds of times per second, measuring blood flow and counting the number of heartbeats each minute.

Additionally, how many times your heart beats each minute (Beats Per Minute) is depicted under the BPMs section. Adults typically have resting heart rates of 60 to 100 BPM.

Temporarily turn off Apple Watch green light

The steps listed below will temporarily turn off the green light on your Apple Watch if you don’t want to disable it permanently.

  1. Finish Heart Rate monitoring: Hold off until your heart rate has been recorded. While it is measuring your heart rate, the green light flashes continually. It will switch off automatically after completion. So, simply ignore it for a bit.
  2. End a breath or reflection session: Swipe right and choose End when in a breath or reflection session. This ends the session and disables the green light while turning off the heart rate.
  3. Stop a workout session: Swipe right on the Apple Watch display and choose End. This will end your workout and break heart rate monitoring, turning off the green light.

One of the prominent reasons that the green light isn’t working on your Apple Watch could be that you may have unintentionally disabled your Apple Watch’s Heart Rate functionality.

Q. Why is the green light on my Apple Watch on when I’m not wearing it?

Q. What happens after you disable Heart Rate on your Apple Watch?

While you’re wearing it, the heart rate tracking ends when you turn off the heart rate function, which also permanently turns off the green light emission.

Wrapping up…
