The Garmin Instinct smartwatch is a device that can monitor your sleep. It does this by tracking your heart rate data, stress levels, sleep quality, and overall activity to calculate a score that represents your energy or body battery level. This level ranges from 0 to 100. The watch establishes your baseline heart rate while you are awake, and you only need to wear the watch for at least two hours before going to bed for it to do this. This baseline allows the Garmin to automatically start tracking your sleep when your heart rate slows far enough below this level. While you sleep, the watch will track information about the quality of your sleep, including the total amount of time you slept, and the amount of time spent in different stages of sleep, such as deep sleep, light sleep, REM sleep, and being fully awake.
| Characteristics | Values |
|---|---|
| How it works | The watch establishes your baseline heart rate while awake when worn throughout the day. It automatically starts tracking your sleep when your heart rate slows far enough below this level. |

What You'll Learn
How to set up your Garmin Instinct sleep tracking
To set up your Garmin Instinct sleep tracking, you will need to first create a Garmin Connect account. You can do this by installing the Garmin Connect app on your Android or iOS device. Once you have created your account, you can start wearing your watch.
The watch will establish your baseline heart rate while you are awake, so it is recommended to wear the watch for at least two hours before going to bed. This baseline allows the watch to automatically start tracking your sleep when your heart rate slows far enough below this level.
You can also manually set your normal sleep hours in the user settings on your Garmin Connect account. However, this is not necessary as the watch will automatically detect your sleep.
While you are sleeping, the watch will track the quality of your sleep, including your heart rate data, stress levels, sleep quality, and overall activity. All of this data is then logged and charted on your Garmin Connect account.
To view your sleep statistics, open the Garmin Connect app and tap the menu icon at the upper left. From the menu, tap Health Stats and select Sleep. Here, you will be able to view the total amount of time you slept the previous night, as well as details for previous nights. You will also be able to see the total time you were in different stages of sleep, including deep, light, REM, and fully awake.

How the watch detects when you're asleep
The Garmin Instinct smartwatch uses a combination of photoplethysmography (PPG) and actigraphy (ACT) data to determine whether you are awake, asleep, or up for a toilet break, and which sleep stage you are in. The watch establishes your baseline heart rate while you are awake when you wear the watch throughout the day. You need to wear the watch for at least two hours before going to bed to establish this baseline. This baseline allows the watch to automatically start tracking your sleep when your heart rate slows far enough below this level.
The watch also uses heart rate variability, or the time between each heartbeat, to measure your time awake and time spent in each sleep stage. The sleep stages that the watch tracks are awake spells, REM, light sleep, and deep sleep. The watch also tracks your respiration rate, or how many breaths you take per minute while sleeping. This is an important metric as it can be used to understand potential sleep issues.
The watch also uses your heart rate data, stress levels, sleep quality, and overall activity to calculate a score that represents your energy or "body battery" level. This level ranges from 0 to 100, with 100 being maximum energy. This feature relies on sleep metrics to inform its figures, so it is another way to understand how your sleep will affect your day.

How the watch tracks your sleep quality
The Garmin Instinct smartwatch uses a combination of heart rate data, stress levels, sleep quality, and overall activity to calculate a score that represents your energy or "body battery" level. This level ranges from 0 to 100, with 100 indicating maximum energy. The watch establishes your baseline heart rate while you are awake by tracking your heart rate throughout the day. You only need to wear the watch for at least two hours before going to bed to establish this baseline. This baseline allows the Garmin to automatically start tracking your sleep when your heart rate slows far enough below this level.
While you sleep, the watch will track information about the quality of your sleep, including the total amount of time you slept, the number of breaths you take per minute, and the amount of time spent in different stages of sleep, such as deep sleep, light sleep, REM sleep, and being fully awake. This data is then logged and charted on your Garmin Connect account, which can be accessed through the Garmin Connect app.
It is important to note that the accuracy of the sleep tracking data may depend on the fit of the device. If the watch is not tight enough against your skin or is too compressed, the heart rate monitor may lose track of your heart rate, resulting in skewed data. Additionally, the most common reason for missing advanced sleep monitoring data is related to the heart rate monitor being turned off, which can be due to battery-saving modes.
Garmin's Sleep Coach feature recommends the optimal amount of sleep for your body based on your current activity load, sleep history, and recovery status. The company's Advanced Sleep Monitoring product, available on most of its smartwatches and fitness trackers, provides more detailed insights into your sleep patterns by tracking several metrics, including heart rate variability and the device's accelerometer to understand when you are sleeping and the stage of sleep you are in.

How to access your sleep data
To access your sleep data, you must first install the Garmin Connect app on your Android or iOS device. You should also ensure that you have created and set up your Garmin Connect account before your first night of wearing the watch.
Once you have the app, open it and tap the menu icon at the upper left to view your sleep statistics. Tap Health Stats from the menu, and select Sleep. Here, you will find many statistics, including the total amount of time you slept the previous night. You can swipe to the side to access details for previous nights. You will also be able to see the total time you were in different stages of sleep, including deep, light, REM, and fully awake.
Scrolling down will reveal a graph showing the exact times these sleep stages occurred throughout the night. The Sleep statistics area is where your main sleep data is displayed, but your sleep stats are also used for other health statistics in the app. For example, sleep stats are incorporated into two other widgets in the Garmin Connect app, which show the last 24 hours of activity in a pie chart.
If your Garmin sleep data shows certain periods as 'Unmeasurable', this likely means that your watch was not tight enough against your skin, or it was too compressed, resulting in skewed data.

How the watch can help you improve your sleep
The Garmin Instinct smartwatch is a great tool to help you improve your sleep. The watch has a feature called Sleep Coach, which recommends the optimal amount of sleep for your body based on your current activity levels, sleep history, and recovery status. This feature can help you set a sleep schedule that ensures you get the right amount of rest each night.
The watch also has advanced sleep monitoring capabilities that can track your sleep time and quality. It does this by using your heart rate data, heart rate variability, stress levels, sleep quality, and overall activity to calculate a "body battery" score, which represents your energy reserves for the day. This score ranges from 0 to 100, with higher scores indicating higher energy levels. By tracking this data, the watch can provide insights into your sleep patterns and help you identify areas for improvement. For example, if you consistently have a low body battery score, you may need to prioritize getting more sleep or improving your sleep quality.
Additionally, the watch can track your blood oxygen saturation levels and respiration rate while you sleep. These metrics are important as they can indicate potential sleep issues like sleep apnea. While the watch cannot diagnose sleep apnea, it can provide valuable data that can help you decide when to see a doctor.
To ensure accurate sleep tracking, it's important to wear your watch correctly during sleep. Make sure the heart rate monitor is turned on and that the watch is fitted snugly against your skin. By utilizing the insights and data provided by the Garmin Instinct smartwatch, you can make informed decisions to improve your sleep quality and overall health.
