How Active 2 Tracks And Improves Sleep Quality

The Samsung Galaxy Watch Active 2 is a sleek smartwatch that offers built-in sleep-tracking. It uses movement and heart rate to determine whether the wearer is awake or in light, deep, or REM sleep phases. This data is tracked in the Samsung Health app, which can be viewed on the watch or a smartphone. The watch offers lengthier battery life, functional FDA-cleared health features, and big-name apps. Reviews suggest that the watch's sleep-tracking could be more useful with some fine-tuning, as it occasionally gets mistaken and starts tracking sleep when the wearer is awake.

The Samsung Galaxy Active 2 tracks sleep via movement and heart rate

The Samsung Galaxy Active 2 is a sleek smartwatch that comes with a host of features, including sleep tracking. The device uses movement and heart rate to track sleep and differentiate between the various phases of sleep. This data is then recorded in the Samsung Health app, which can be viewed on the watch or a smartphone.

Sleep tracking is an important feature for many consumers, and Samsung has integrated this functionality into its Galaxy smart watches and the Samsung Health app. The Samsung Galaxy Active 2, in particular, offers insights into sleep patterns and makes sleep tracking convenient and accessible. By using movement and heart rate, the watch can determine whether an individual is awake or in light, deep, or REM sleep phases.

Heart rate is a key indicator of sleep phases. When awake, an individual typically has a higher heart rate compared to when they are asleep, except during REM sleep, where heart rate can be more variable and similar to wakefulness. During light sleep (stages 1 and 2), the heart rate begins to slow down as the body becomes less active and requires less oxygen. In deep sleep (stage 3), the heart rate reaches its lowest level as the body is completely relaxed.

Movement also plays a role in sleep tracking. In the initial stages of light sleep, an individual is more likely to move around, although these motions are less controlled than when they are awake. During deep sleep, there is minimal to no movement. REM sleep is similar to deep sleep in terms of movement, but it differs in that the brain turns off the nerves controlling large muscle groups, resulting in temporary paralysis.

The Samsung Galaxy Active 2 combines heart rate and movement data to provide insights into sleep patterns. While sleep tracking technology has a history of being inaccurate, the combination of these two data points allows the device to more accurately differentiate between sleep phases and provide valuable information to users about their sleep quality and duration.

It differentiates between awake, light, deep and REM sleep

The Samsung Galaxy Active 2 uses movement and heart rate to differentiate between awake, light, deep, and REM sleep phases. This data is tracked in the Samsung Health app, which can be viewed on the watch but is recommended to be viewed on a smartphone.

During the REM sleep phase, your eyes move around rapidly in different directions, and your brain is active. Your brain activity is similar to its activity when you're awake. Dreams typically happen during REM sleep. During non-REM sleep, your brain is not as active. In the deeper stages of non-REM sleep, your breathing slows down, and your blood pressure drops.

REM sleep is important for brain functions such as learning and memory. During this stage, your brain repairs itself and processes emotional experiences. Non-REM sleep, on the other hand, is when the body relaxes fully and repairs itself.

The Samsung Galaxy Active 2's sleep-tracking feature has been praised for its accuracy and ability to provide a breakdown of light, REM, and deep sleep. However, some users have reported occasional inaccuracies in determining the exact time they fell asleep.

The Samsung Health app presents sleep data

The Samsung Health app is a comprehensive tool for tracking and managing your health and fitness. It is available on both the Galaxy Watch Active 2 and smartphones. The app provides valuable insights into your sleep patterns, helping you to optimise your sleep schedule and achieve your fitness goals.

To use the sleep monitoring feature on the Samsung Health app, you must first ensure that your Galaxy Watch Active 2 is connected to your phone via the Galaxy Wearable app. When you're ready for bed, secure your watch to your wrist and place your phone near your head. The app will then monitor and record your sleep patterns, including your sleep stages such as REM, light sleep, deep sleep, and awake time.

The following morning, you can review your sleep data by opening the Samsung Health app and tapping the Sleep tab. Here, you will find detailed information, including your sleep score, sleep time, and a breakdown of the different sleep stages. The app also offers sleep coaching options to help you improve your sleep quality.

In addition to sleep tracking, the Samsung Health app also allows you to monitor your snoring. To enable this feature, you can turn on Snore Detection in the app settings. The app will then detect and record your snoring, providing you with data that you can review the next day.

The Samsung Health app is a powerful tool for understanding and improving your sleep. By tracking your sleep patterns and providing coaching options, it helps you optimise your sleep schedule and enhance your overall health and well-being.

The LTE version of the watch is said to last about 24 to 36 hours on a single charge.

The Samsung Galaxy Watch Active 2 has a longer battery life than its predecessor, the original Galaxy Watch Active. The Active 2 has a battery life of about two days with heavy usage, while the original Active had to be charged every day, according to a user. The Samsung Galaxy Watch Active 2 is also said to have a longer battery life than Wear OS watches.

The Samsung Galaxy Watch Active 2 has a longer battery life than the Apple Watch. The Apple Watch Series 5 only lasts about 18 hours with its always-on display, while the Active 2 lasts about 24 hours with the always-on display turned on. The Apple Watch Series 6 is said to be the best smartwatch on iOS, but the Active 2 has a longer battery life, making it a good option for Android users.

The Samsung Galaxy Watch Active 2 has a longer battery life than the Fitbit. While the Fitbit can last almost a week on a single charge, the Active 2 has a battery life of about two days with heavy usage, which is still much longer than the Fitbit. The Samsung Galaxy Watch 3, which is the next version of the Active 2, has all the features of the Active 2 but with a longer battery life.
