Is Samsung Health Any Good?

Undoubtedly, the Samsung Health app has a lot of benefits because it does not only help you record and monitor your sleep, but also aids in helping you change your other habits. That includes exercising and diet changes. With that in mind, let’s focus on how useful it is when it comes to monitoring your sleep.

Sleeping Habit Monitoring

Most of the time, we have our standard sleeping and waking up times. With the help of our natural body clock or circadian rhythm, we automatically feel sleepy when it’s our regular sleeping time and wake up when it’s our regular waking time. This, though, is not always the case.

There are days, especially weekends, when we have too much caffeine or are busy with some other things that we or our body can’t sense that it’s time to rest your head on your comfortable, shoulder-zoned memory foam pillow (view on Amazon). If you want to stick to a regular sleep schedule to have better sleep quality, the Samsung Health app will provide you specific data, whether or not you followed your sleep schedule.

It will also help you determine the total number of hours you were asleep and will create a graph that you can analyze to see if you are experiencing sleep deficit.

Interrupted Sleep Determination

Your Samsung Gear S3 watch sleep tracker, together with the Samsung Health app will help you identify if you have been experiencing interrupted sleep, which might or might not require professional help. When your tracker is on silent or sleep mode, without any body movement, it will detect it as you sleeping. On the contrary, if it detects any body movement, it will be recorded as restless sleep.

These movements might be caused by your typical tossing and turning around your innerspring mattress (view on Amazon) or maybe due to sleeping problems such as apnea and restless leg syndrome. This may also be because of some noise or light around your room that causes disruptive sleep. Thus, inspect accordingly or consult a doctor.

Specific Sleeping Stage Problem

Even if you have completed the number of hours you sleep regularly, there are days when you wake up exhausted. The reason for this is that you might have awakened during the deep stage of sleep. Your sleep tracker will help you see the time when you usually achieve the deep sleep stage, so you can adjust your alarm or waking time.

Although not as accurate as traditional methods, achieving quality sleep and determining possible sleeping problems are possible with the help of Samsung wearable sleep trackers and apps. Just make sure you follow the tips above on how to use sleep tracking on Samsung Gear S3, as well as understand the different data provided by the device and the app.
