Moreover, there are many more features to discover within the Samsung Health app, such as counting your steps or recording your exercises.

Can this measurement tell me something important?

Our heart can be considered one of the most important organs in our body and knowing or monitoring our heart rate can be useful to help us detect any sudden changes or anomalies but we shouldn’t just consider this measurement but also visit a physician.

As recommended on samsung.com, “If you have an implantable medical device, such as a pacemaker, please consult your doctor or health care provider before using any handheld or wearable wireless mobile device and carefully review the health and safety manual for your device model for tips on preventing interference. For additional information www.fcc.gov/oet/rfsafety/rf-faqs.html”.

How accurate is it?

Just like with any other device, the accuracy will depend on several factors such as issues with the software, environmental conditions, skin condition, specific activity performed while using the device, settings of the device and/or user configuration. Moreover, it is recommended to read the manual for more information on how to use the device properly.

However, before you start monitoring your heart rate with any device or wearable and before you start any physical activity, especially if you have a medical or heart condition, consider discussing it with a professional so they can assess your health and can help you create an exercise program fit for you.

As advised by Samsung, “While the heart rate sensor on your device can be a useful tool for motivating you and tracking your exercise intensity, the heart rate sensor and compatible Samsung Health application are not medical devices and are not intended to diagnose, treat or prevent a disease or medical condition”.

What do the different statuses mean?

If you are going to measure your heart rate using the sensor, select the status depending on your level of activity when measuring. Additionally, the general status is best measured when you are not resting, meaning not laying in bed or your couch but also avoid measuring when working out. 

The before exercise status is best measured after warming up or stretching before a workout. Also, you can see the resting status which is best measured when you wake up or after you have been sitting still for at least 5 minutes. Finally, the after exercise status is best measured directly after working out.

How to measure my heart rate with my device or wearable?

When you are measuring your heart rate, ensure the device fits in your arm and wrist but without making you feel uncomfortable. Try not to fasten it too tightly and if it feels uncomfortable, becomes hot to the touch, remove until it cools down.

In contrast, when measuring your heart rate with your Samsung device, place your finger on the sensor and press it lightly. 

Additionally, if you have Galaxy Buds and you would like to measure your heart rate, make sure to check the direction of each earbud and insert them into your ears facing upwards until they sit comfortably in your ears. Adjust the earbuds by rotating them to the left or right, so it can fit your ears. The heart rate sensor will automatically detect them once inserted and they will automatically turn on and emit a beep sound.

  • Try to take the measurements when you are seated and relaxed. Avoid moving while it takes the measurements since it can record your heart rate inaccurately.
  • If the measurement you see is very different from the expected heart rate measurement, rest up to 30 minutes and measure again. 
  • Users with thin wrists may get inaccurate readings.
  • The measurements are calculated using average values and you may need to take them a couple of times before you get an accurate reading.
  • Avoid taking measurements when drinking or smoking since it can cause your heart rate to be different from your normal heart rate.
  • Avoid looking directly into the heart sensor’s light since doing so may impair your vision.
  • If the sensor is nor working properly, try adjusting the position on your wrist for better reading.
  • If the sensor becomes dirty, try wiping it and try again.
  • If you have an implantable medical device (i.e. peacemaker) keep your mobile device more than 6 inches from your implantable device when the phone is on. Also, avoid carrying the device in your breast or the front pocket of your shirt.
