From Restless to Restful: How to track sleep with a smartwatch and Achieve Better Rest

If you’re having trouble getting a good night’s sleep, a smartwatch can be a great tool to help you track your sleep and make informed decisions to improve the quality of your rest. 

We’ll cover how to activate sleep mode on your smartwatch, the best smartwatches for sleep tracking, and how sleep trackers measure deep sleep and overall sleep quality.

How to Activate Sleep Mode in Smartwatch

Activating sleep mode in your smartwatch is a simple process that varies slightly depending on the model and brand of your device. Generally, you’ll need to follow these steps:

  • Navigate to the sleep tracking feature in your smartwatch app or settings.
  • Select “Start-Sleep” or a similar option.
  • Wear your smartwatch to bed, and it will automatically track your sleep.
  • It’s important to note that not all smartwatches have a built-in sleep tracking feature, and some may require the installation of a third-party app to activate sleep tracking. Be sure to check your device’s manual or support resources to learn more about activating sleep mode.

Best Smartwatch for Sleep Tracking

When it comes to tracking your sleep, some smartwatches are more accurate and reliable than others. Here are some of the best smartwatches for sleep tracking:

Apple Watch Series 6: The latest Apple Watch model features advanced sleep tracking capabilities, including automatic sleep detection and a dedicated Sleep app.

Samsung Galaxy Watch 3: With its high-quality sleep tracking sensors and long battery life, the Galaxy Watch 3 is a great option for tracking your sleep.

Fitbit Sense: Fitbit has long been a leader in sleep tracking technology, and the Sense model offers advanced features like a skin temperature sensor and personalized sleep score.

Garmin Venu 2: The Venu 2 boasts a range of health and fitness tracking features, including detailed sleep tracking and analysis.

How Do Fitness Trackers Track Deep Sleep?

Deep sleep is a crucial stage of the sleep cycle that helps your body recover and rejuvenate. Most fitness trackers and smartwatches use a combination of heart rate and motion sensors to track deep sleep. During this stage, your heart rate slows down, and your body becomes less responsive to movement. By analyzing changes in your heart rate and motion data, your smartwatch can determine when you’re in a deep sleep and how long you stay in that stage.

Sleep Tracker: How is Deep Sleep Measured?

Deep sleep is measured in two ways: duration and intensity. Duration refers to the amount of time you spend in a deep sleep each night, typically measured in hours and minutes. Intensity refers to how deep your sleep is during that time, which is measured in a variety of ways, such as brain waves, muscle activity, and heart rate.

How to Measure Sleep Quality

Sleep quality is a measure of how restful and restorative your sleep is. While there are many factors that can affect sleep quality, there are a few key metrics that sleep trackers use to measure it. These include:

  • Sleep duration: The total amount of time you spend asleep each night.
  • Sleep efficiency: The percentage of time you spend in bed actually asleep.
  • Wake-up times: The number of times you wake up during the night.
  • Resting heart rate: Your average heart rate during sleep.
  • Deep sleep percentage: The percentage of time you spend in deep sleep.

By tracking these metrics over time, you can better understand your sleep patterns and make informed decisions to improve the quality of your rest.


In conclusion, a smartwatch can be a valuable tool for tracking your sleep and improving your overall health and well-being. By activating sleep mode in your smartwatch, choosing a high-quality device with advanced sleep tracking features
