The Fitbit Versa is a popular smartwatch that has been praised for its ability to track sleep. The device can be worn on the wrist or leg and uses an accelerometer to infer when the wearer is sleeping and what stage of sleep they are in. This is done by measuring bodily accelerations of the wrist and using a technique called optical photoplethysmography (PPG) to measure blood flow. The Fitbit Versa also features an SpO2 sensor for measuring blood oxygenation, however, this feature is not currently used by the Fitbit app. The sleep-tracking feature on the Fitbit Versa has been praised for its ability to provide in-depth insights into the user's sleep patterns, including the number of hours slept, sleep score, sleep schedule, and sleep stages.

What You'll Learn
The Fitbit Versa 2 has a sleep-tracking feature
The Fitbit Versa 2 uses accelerometer data, heart rate variability, and algorithms to estimate how long you spend in each stage of sleep. This allows the device to infer whether you are awake, in a deep sleep, a light slumber, or dreaming. Additionally, the Fitbit Versa 2 has an SpO2 sensor that measures blood oxygenation levels, which has the potential to provide valuable feedback for people with sleep apnea. However, this feature is not currently utilised by the Fitbit app and will be released once government approval is granted.
The Fitbit app also offers a sleep profile feature, which is available with a Fitbit Premium subscription. This subscription service includes several guided health programs and provides more detailed insights into your sleep patterns and quality. The app allows you to review your sleep data, including your sleep score, hours slept, sleep schedule, and sleep stages. It also enables you to compare your sleep stats with others.
The Fitbit Versa 2 has a long battery life, a reasonable price, and a more premium look and feel compared to previous versions. It also includes subscriber programs like Premium and Coach, as well as always-on features like Alexa. The device can be controlled by swiping the silky glass face or pushing a button on the left side.

The device monitors your heart rate while you sleep
The Fitbit Versa 2 is a smartwatch that can be used to track sleep. It has a sleep-tracking feature that monitors your heart rate while you sleep. The device uses accelerometer data, heart rate variability, and algorithms to estimate how long you spend in each stage of sleep. This includes the awake, REM, light, and deep sleep stages. The Fitbit app provides insights into your sleep patterns, such as the number of hours slept, sleep score, sleep schedule, and the time spent in each sleep stage.
To use the sleep-tracking feature, you need to open the Fitbit app and tap "Begin Sleep Now" in the Today tab. The device will then monitor your heart rate throughout the night. When you wake up, you can sync your device to view your sleep data in the app. This includes your sleeping heart rate, time spent in each sleep stage, and your overall Sleep Score. Fitbit assigns a Sleep Score based on your sleep data, which takes into account factors such as sleep duration and quality.
The Fitbit Versa 2 also offers a Smart Wake feature, which is an alarm that picks the best time to wake you up within a 30-minute window based on your sleep cycle. This can help you feel more rested and less grumpy in the morning. Additionally, the device can detect snoring and noise levels during sleep, providing a summary report when you wake up.
It is recommended to wear the Fitbit Versa 2 on your wrist during sleep, as this is the most comfortable and effective placement for sleep tracking. The device has a long battery life and is reasonably priced, making it a popular choice for those seeking to improve their sleep habits and overall well-being.
Overall, the Fitbit Versa 2 is a useful tool for monitoring your heart rate and sleep patterns, providing insights, and helping you make informed decisions to optimize your sleep quality.

Fitbit assigns you a Sleep Score
Fitbit's sleep-tracking feature can help you understand your sleep patterns and quality. The Fitbit app provides a Sleep Score, which is a detailed look into your sleeping patterns, helping you develop healthier habits. The score is based on your heart rate, the time spent awake or restless, and your sleep stages.
Sleep Stages refer to the different phases of sleep that your body cycles through during the night. These include REM, light, and deep sleep. Fitbit estimates these sleep stages by using your movement and heart rate patterns. When you don't move for about an hour, your Fitbit assumes you're asleep. It also tracks changes in your heart rate, known as heart rate variability (HRV), which fluctuate as you transition between sleep stages.
Your overall Sleep Score is the sum of your individual scores for time asleep, deep and REM sleep, and restoration, with a total score of up to 100. The average score ranges from 72 to 83. Restoration is based on your sleeping and resting heart rates and how much time you spent tossing and turning. You receive a higher restoration score when your sleeping heart rate is lower than your daytime resting heart rate.
To access your Sleep Score, go to the Today tab in the Fitbit app and tap the Sleep duration tile. You can then tap the Sleep score tile to see your individual scores for each metric. On certain devices, you can also check your Sleep Score from your wrist. Additionally, you can review your sleep data, including your sleep stages and sleeping heart rate, with a Fitbit Premium subscription.
The Fitbit sleep-tracking feature can provide valuable insights into your sleep habits and help you make adjustments for better sleep quality. By understanding your sleep patterns, you can strive for the recommended seven to eight hours of sleep for optimal health.

The Fitbit Versa has an SpO2 sensor for measuring blood oxygenation
The Fitbit Versa is a popular device for tracking sleep. It can monitor your heart rate while you sleep, and with a premium subscription, it can also show your sleeping heart rate and how much time you spent tossing and turning. The Fitbit Versa 2 even has a Smart Wake feature, which picks the best time to wake you up within a 30-minute window based on your sleep cycle.
It is important to note that the SpO2 data is intended to be a close estimation of blood oxygen saturation levels, but it may not be precisely accurate. It should not be used or relied on for medical purposes. The SpO2 data can be accessed by installing an SpO2 clock face or the SpO2 app. For the Versa, Versa Lite Edition, and Versa 2, SpO2 data is only collected when using an SpO2 clock face.
By tracking blood oxygen saturation with the SpO2 sensor, Fitbit users can uncover important changes in their fitness and wellness. This data can help users understand their body's ability to maintain blood oxygen levels and identify potential issues. For example, low SpO2 values at high altitudes may indicate the need to descend to a lower altitude.

Frequently asked questions
No, the Fitbit Versa is not designed to be worn on the leg during sleep. It is intended to be worn on the wrist, where it can detect your sleep patterns by monitoring your heart rate and movement.
The Fitbit Versa infers when you’re sleeping and what stage of sleep you’re in using an accelerometer (an instrument for measuring bodily accelerations of the wrist) coupled with a technique called optical photoplethysmography, or PPG. PPG measures blood flow based on how green light from an LED on the back of the watch is reflected by the body. It also uses heart rate variability and algorithms to estimate how long you spend in each stage of sleep.
Sleep can be broadly divided into rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep. During REM sleep, you are most likely to be dreaming, while during NREM sleep, you are more likely to be in a dreamless sleep. Deep sleep and light sleep are types of NREM sleep.
Tracking your sleep with the Fitbit Versa can help you understand your sleep patterns and improve your sleep quality. The device provides insights into how much time you spent in each stage of sleep (awake, REM, light, and deep) and assigns you a Sleep Score. It also has a Smart Wake feature, which is an alarm that picks the best time to wake you up in a 30-minute window based on your sleep cycle.
