How Galaxy Watch Tracks Your Sleep

The Samsung Galaxy Watch is a great device for tracking sleep. It can monitor the quality and length of sleep, as well as the factors contributing to a good or bad night's rest. The watch uses an accelerometer to detect movement and combines this with user data from its sensor array. It can also sample body temperature throughout the night, which is used in several other metrics. In addition, the watch can track blood oxygen saturation, an important metric for gauging the body's efficiency, and it can detect snoring. The data is collated and displayed in the Samsung Health app, where users can access a sleep score and view their sleep data in chart and graph form.

The Samsung Health app and Sleep tile

The Samsung Health app, in conjunction with the Sleep tile, offers a comprehensive sleep monitoring system for the Galaxy Watch. The app provides a detailed analysis of your sleep patterns and habits, helping you understand and improve your sleep quality.

To access sleep data on the Samsung Health app, you must first ensure that your Galaxy Watch is connected to your phone via the Galaxy Wearable app. Once connected, you can launch the Samsung Health app on your phone and tap the Sleep tile. Here's a step-by-step guide to accessing the Sleep tile:

• Open the Samsung Health app on your Galaxy Watch.
• Swipe left on the watch's Home screen until you see the Sleep tile.
• Tap the Sleep tile.

The Sleep tile offers a wealth of information about your sleep. It includes the following data:

• Sleep Score: This rates your sleep quality on a scale, typically from Excellent to Needs Attention, with a numeric score between 1 and 100. A higher score indicates better sleep.
• Sleep Time: Displays your sleep duration in hours and minutes, as well as the calories burned during sleep.
• Sleep Stage: Breaks down your sleep into different stages, including Awake, REM, Light, and Deep sleep cycles.
• Blood Oxygen During Sleep: Shows your blood oxygen saturation percentage, an important metric for assessing your body's efficiency and health.
• Snore Detection: Records and measures the amount of time you spent snoring.
• Sleep Skin Temperature: Monitors your body's skin temperature during sleep.
• Sleep Consistency: Tracks the number of days in the current week that you've achieved your sleep goals.

Additionally, the Samsung Health app offers sleep coaching options to help you optimize your sleep. It provides a tailored sleep coaching program based on your survey results and sleep pattern data. This feature requires you to wear your watch for at least 7 days and nights before it can be utilized, and the settings can only be adjusted from your connected phone.

The Sleep tile on the Samsung Health app offers a detailed and informative overview of your sleep patterns, providing valuable insights to help you understand and improve your sleep quality.

Snoring detection

The Samsung Health app on the Galaxy Watch has a snoring detection feature that allows you to monitor your snoring while you sleep. The watch can detect and record your snoring, and the data is compiled in the Samsung Health app, which you can check the next morning.

To use the snoring detection feature, you need to ensure that your Galaxy Watch is connected to your phone via the Galaxy Wearable app. You can then open the Samsung Health app on your phone and tap the Sleep tile or card. From there, you can enable snoring detection by tapping on Advanced Measurement and then Snoring. You will need to allow the necessary permissions and may also need to turn on blood oxygen tracking. You can also choose to record your snoring by tapping the switch next to Record Audio.

The following morning, you can check your snoring data by opening the Samsung Health app and tapping on the Sleep tracker. You can then swipe to and tap the data under Snoring. The app will show you the amount of time you spent snoring, and you can even listen to recordings of your snoring.

It is important to note that the snoring measurement and recording are done on your phone, so you will need to place your phone near your head when you sleep. Additionally, the watch must be securely attached to your wrist and the phone should be on a stable surface, such as a nightstand.

The snoring detection feature on the Galaxy Watch provides a convenient way to monitor your snoring and can help you better understand your sleep patterns and overall sleeping health.

Sleep coaching options

The Galaxy Watch series offers a range of sleep coaching options to help you improve your sleep quality. Here are some of the key features:

Sleep Monitoring and Tracking

The Galaxy Watch uses the Samsung Health app and the Sleep tile to monitor and track your sleep patterns. It can record your sleeping time, detect and record snoring, and measure blood oxygen levels during sleep. This data is then used to provide insights and coaching tips to improve your sleep.

Sleep Coaching Program

Based on your sleep data and answers to initial questions, the Samsung Health app assigns you a "sleep animal" symbol, representing your sleeping style. The app then creates a personalized four-to-five-week coaching program tailored to your sleep needs. This program includes missions, checklists, sleep-related articles, meditation guidance, and sleep reports.

Smart Device Control

The Galaxy Watch can help you maintain a consistent sleep schedule by integrating with your smart devices. You can connect your smart devices, such as your TV, to the SmartThings app on your phone. This allows you to set them to shut off at a particular time, ensuring you don't stay up too late and helping you stick to your sleep schedule.

Bedtime Mode

To create a peaceful sleep environment, you can enable Bedtime Mode, which cancels all audio and vibration alerts except for your alarm. Features like Always-on display, touch screen to wake, and raise wrist to wake are also disabled during Bedtime Mode.

Advanced Sleep Insights

The Galaxy Watch also provides advanced sleep insights, including sleep stages (Awake, REM, Light, and Deep sleep cycles), sleep skin temperature, and sleep consistency. These insights give you a comprehensive understanding of your sleep patterns and areas that may need improvement.

Snore Detection

In addition to recording your snoring, the Galaxy Watch offers Snore Detection, which requires connecting your watch to your phone via the Galaxy Wearable app. This feature allows you to measure and record snoring while you sleep, providing insights into your sleep quality.

Sleep score

The Samsung Health app on the Galaxy Watch provides a sleep score, which rates sleep quality on a scale of "Excellent", "Good", "Fair", and "Needs Attention". This score is based on a variety of factors, including sleep time, sleep stages, blood oxygen levels, and sleep consistency.

Sleep time is the amount of time spent sleeping, which is measured in hours and minutes. It also includes calories burned during sleep. Sleep stages refer to the different stages of sleep, including Awake, REM, Light, and Deep sleep cycles. The Galaxy Watch records the amount of time spent in each of these stages. Blood oxygen levels are measured during sleep, and this data is available to view the next morning. Sleep consistency shows the number of days in the current week that sleep goals have been met.

The sleep score also takes into account movements and awakenings during sleep. This is the percentage of sleep that is interrupted, with a range of 10% to 40% being ideal. Physical recovery is related to deep sleep, which is considered the physically restorative phase. Mental recovery is associated with REM sleep, which is important for mental recovery. A figure of 60% or above in REM sleep will contribute to a high sleep score.

While the sleep score provides an overall rating of sleep quality, it is important to consider the various factors that contribute to this score. By understanding these factors, users can gain insights into their sleep patterns and make informed decisions to improve their sleep.

Blood oxygen saturation

Oxygen saturation measures how much haemoglobin is bound to oxygen compared to how much remains unbound. Haemoglobin consists of four globular protein subunits, each associated with a heme group. Each haemoglobin molecule has four heme-binding sites available to bind oxygen, meaning it can carry up to four oxygen molecules during oxygen transport in the blood.

There are two main ways to measure or test blood oxygen levels: through a blood draw test and through pulse oximetry (using an oximeter). A blood draw test provides much more information about your oxygen levels than an oximeter does. A pulse oximeter is a non-invasive device placed over a person's finger or toe and can be used at home or in a medical setting. It is a quick and harmless way to check if someone's blood oxygen level is too low.

The Samsung Galaxy Watch can help you monitor your blood oxygen saturation during sleep. With the Samsung Health app and Sleep tile, you can view your blood oxygen percentage. To use this feature, you need to enable it in the Samsung Health app and ensure your watch is connected to your phone via the Galaxy Wearable app.
