Because the green lights are utilized to measure heart rate, there’s no reason to turn them off. However, there are situations when the watch takes measurements mistakenly.

For example, if the watch is not being worn but the green lights are on, it could result from a workout still in progress.

So, During these times, the Apple Watch will monitor the heart rate more frequently and causing the lights to activate more often. The green lights will automatically turn off if you stop working out.

In case you wish to turn off the green lights, that means that you are automatically going to turn off the heart rate sensor. 

Follow the steps below to turn off the green light on an Apple Watch:

  • On your iPhone, open the Watch app and select “My Watch” at the bottom of the screen.
  • Scroll down and select “Privacy” from the drop-down menu.
  • Tap “Motion and Fitness” when you find it.
  • Toggle the button to turn off “Heart rate” in the new window.
  • Done

You can also turn off the green light in Apple Watch by disabling the heart rate in the Starve in the Apple Health App.

Why Is The Green Light On My Apple Watch Always On?

Please refer to the instructions above or restart your watch to turn it off completely.

To switch off your watch, press and hold the side button until the “Power Off” slider appears, then move it to turn it off.

Why is the green light always on even when the watch is not on my wrist? 

It isn’t very pleasant if your smartwatch’s green light doesn’t turn off even after taking it off your wrist. And staying ON also depletes your battery more quickly.

Here are various methods or fixes you can try without compromising your Apple watch’s warranty.

Ensure you have the most recent versions of the Apple Watch OS and the Apple Health App on your smartphone before proceeding.

  • Please restart your Apple Watch after turning it off. If that doesn’t work, move on to step 2

Are the green lights bad for you?

The simple answer is no; the green LEDs under your Apple Watch are extremely low-power and will not burn or hurt your skin in any way. 

They’re also set to switch off automatically when you’re not actively measuring your heart rate using the watch.

In theory, led lights are also safer because they have low ionizing power and do not release ultraviolet rays emitted by common light bulbs and fluorescent lamps.

It’s also uncommon to encounter people having skin irritation from the led lights emitted by smartwatches when they’re recording your heart rate.

If the green light from your Apple Watch is irritating your skin, you should slow down how often you put it on and consult a doctor since you could be suffering from porphyria.

Newer Apple Watch models contain an internal ECG sensor/electrode on the digital crown, which can detect your heart rate more accurately than the older optical sensors.

Finally, if you don’t wish to use these led lights for heart rate monitoring, they may be turned off totally. 

How does the Apple Watch measure your heart rate?

The heart rate or pulse rate of the Apple Watch is measured using optical heart rate sensors. The main components of the Apple Watch heart rate sensor are green LED light and light-sensitive photodiodes.

Photoplethysmography is the technology utilized in the Apple Watch to measure heart rate. The technology is very simple. 

Because the color of blood is red, it absorbs green light. When the heartbeats, more blood is pumped into the blood arteries, allowing the blood to absorb more green light with each beat.

With photosensitive electrodes, Apple watches sensors properly measure how much green light is absorbed during each beating, allowing it to determine heart rate.


What do the two green lights on Apple Watch indicate?

The heart rate sensor uses green LEDs. The sensor is designed to collect regular background measurements of your heart rate throughout the day; however, the LEDs are not always lighted for this purpose.

What does the Apple Watch Series 3’s green light mean?

The green lights indicate the continuous pulse monitor. It includes two low-power infrared lights that take your pulse every few minutes and send the information to your phone when it’s in range. 

The green ones are usually used for activity monitoring and provide significantly more accurate data.

What causes the Apple Watch to stop working?

One of the most common reasons for an Apple Watch not turning on is a dead battery. If that doesn’t work, try an alternative charging cable and charger to determine if your charger is defective.

Why does the green light on my Apple Watch stay on?

The green LEDs have a heart rate sensor attached to them. For this purpose, the LEDs are continually lighted, allowing the sensor to capture daily background measures of your heart rate.

Final Words
