This can be due to a variety of reasons, from hardware issues to minor software glitches.Fortunately, there are a few fixes you can try to get your Apple Watch to track your heart rate normally again.
1. Check wrist position
The heart rate sensor on your Apple Watch works best when it's properly worn on your wrist.Be aware that optical heart rate sensors like the Apple Watch use light to detect your heart rate.During exercise or regular activity, the position of the watch may shift, allowing light to leak through, resulting in erratic readings.
Therefore, when exercising, especially when engaging in high-intensity activities, you should ensure that the watch is not worn too low on the wrist, but just above the wrist bone.This reduces the chance of the watch moving too much and ensures consistent contact between the watch and the skin.
2. Check the strap for proper fit
The fit of the strap plays a vital role in heart rate monitoring.If the strap is too loose, the sensor may not maintain consistent contact with the skin.On the other hand, if the strap is too tight, it can restrict blood flow and cause inaccurate readings.Wearing should be snug but comfortable, ensuring that the watch remains stationary during normal movement.
3. Clean the Apple Watch sensors
Daily use can cause sweat and debris to build up on the Apple Watch's heart rate sensor.When these sensors are obstructed, they may not function optimally.Cleaning your Apple Watch sensors regularly ensures that nothing gets between your skin and the watch, which can help you get more accurate heart rate readings.
To clean the sensors, take the watch off your wrist and place it on a soft surface to avoid scratches.Then, gently wipe the sensor with a non-abrasive, lint-free cloth dampened with clean water.When you're done, let the watch dry before putting it back on.
4. Update watchOS
Apple frequently rolls out software updates to fix known bugs and improve performance.If you haven't updated your watch in a while, a pending watchOS update might solve your problem.
You can update your Apple Watch through the Watch app on your iPhone, or by going directly to Settings > General > Software Update.Either way, make sure your wearable is fully charged or plugged in before attempting the update.
5. Restart Apple Watch
Like many electronic devices, the Apple Watch sometimes requires a quick reboot to function properly.If your heart rate sensor is still not working, this simple solution might fix the problem.
Press and hold the side button, then tap the "Power Off" icon in the upper-right corner of the Apple Watch display.Then, drag the "Power Off" slider to the right to turn it off.Now, wait a few seconds, then press and hold the side button again until the Apple logo appears.
6. Reset Apple Watch
If all of the above solutions fail, it might be time to reset your Apple Watch.Doing so will clear all data and restore the Apple Watch to its default settings, fixing any software-related issues affecting heart rate tracking.
To reset your Apple Watch, open the Settings app in watchOS and tap "General."Scroll down and tap Reset.Then, tap Erase All Content and Settings, and select Erase to confirm the action.
Track Heart Rate Easily
Remember, the Apple Watch isn't just a piece of technology, it's an extension of your health toolkit.So the next time you experience a glitch with the built-in heart rate app, take it easy; follow the troubleshooting steps below and you'll be back on track in no time.
