Green light on Apple Watch: What it is and how to turn it off

Quick Answer

Although the Apple Watch is an excellent wearable addition 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 illuminate the Apple Watch’s back.

In this post, I’ll explain what green light is and how to turn it off on your Apple Watch.

What is the green light on my Apple Watch?

Your Apple Watch’s green light is an optical heart sensor that indicates your heart rate. Apple used 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 your 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, the number of 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, according to the American Heart Association.
