What Does it Do?
If you’re an Apple Watch fan, you must realise that all of the versions contain optical sensors that track your heart rate. So the green illumination under your wristwatch is the led lighting generated by these detectors, which lights your wrist and allows you to collect specific and exact pulse rate measurements. Only when an app operating in the backdrop utilises it to continually monitor your heartbeat will the LED turn on.
Other detectors in the Apple Watch, such as the ECG detectors in the newest Apple Watch Series 4 and 5, do not require the green colour to function. Optical monitors, which detect your heartbeat, are not the same as these detectors.
Why is it Always On?
You might be questioning why the green indicator on your Apple Watch is constantly on knowing what it’s for. It’s little to be concerned over. The led colour simply indicates that an application is monitoring your heartbeat using the heart rate sensor. It will continue to illuminate until you totally switch off the pulse rate sensor.
Four Steps to Turn It Off
- Step 1: Open the Watch application on your iPhone device
- Step 2: Select ‘my watch’ present on the bottom left of the app
- Step 3: Click on the privacy settings
- Step 4: Click on ‘heart rate’ and flip the switch off
You can switch off the green signal on an Apple Watch in 4 easy steps. However, even after following through with these steps, there’s a chance the indicator is always on. When an application uses the pulse rate sensor and runs in the surroundings without your knowledge, this occurs. In this case, the only thing you could do is “reset” your wristwatch.
To turn your watch back on, hold down the power button until the “Turn off” indicator appears. Your device will switch off instantly if you drag the slider. To turn it on, tap and hold the power button until the Apple brand appears. When you turn on the wristwatch following the resetting operation, you’ll notice that the light source is now entirely turned off.

Is This Light Safe?
Do you ever become concerned about the green signal on your Apple Watch, fearful that it will damage you in a certain manner? It is natural for us to believe that the lighting that constantly shines over our heads is harmful to us in some manner.
Is there, however, any reason to be concerned? “No,” is the straightforward response. The green led beneath your wristwatch is completely safe for your flesh and has very minimal energy output. You shouldn’t have to be concerned about it burning your skin. The wristwatch is also built in such a manner that when no app is utilising it to detect your pulse rate, it will immediately switch off the green light.
You might be alarmed by the fact that lights can release UV radiation. However, unlike other commonly used bulbs and fluorescent lamps, LED lights do not generate UV radiation. They also have low ionising strength, making them gentle on the skin and hence safer to use.
It’s quite unlikely that you’ll develop irritated skin as a result of the smartwatch’s green light. These LED bulbs just monitor your pulse rate without troubling you. However, if the odds are stacked against you and you are experiencing discomfort or other problems that you believe are being produced by the green signal, you can attempt to slow down the pace at which you put your wristwatch on. When this issue continues for an extended period of time, you should see a professional who can figure out if you have porphyria, a diagnosable skin disorder.
There’s no need to be concerned because the light source can be turned off altogether if you wouldn’t want it to measure your pulse rate. In addition, recent Apple Watch models include an integrated ECG detector electrode, which is better at tracking heartbeat than its ancestors.
