Fitbit Charge 3: Sleep Tracking Special Edition

The Fitbit Charge 3 is a sleek, lightweight, and affordable fitness tracker that has improved on its predecessor, the Charge 2, in nearly every way. It has a heart rate sensor, an SpO2 sensor, and tracks sleep patterns and quality. The Fitbit Charge 3 Special Edition, released in November 2018, features Fitbit Pay as a special feature. This article will explore the question: does the Fitbit Charge 3 Special Edition track sleep?

Sleep tracking

Fitbit Charge 3 offers sleep tracking, giving you a glimpse into your night with details on REM, light and deep sleep. It also measures sleep quality by tracking periods of restlessness, how long it takes the wearer to fall asleep and how long they are actually asleep. Fitbit has also launched a beta version of its "Sleep Score" feature, which will track sleep quality and use the SpO2 sensor to track SpO2 (blood oxygen levels) to help track new health indicators like sleep apnea.

Fitbit was the first wearable brand to offer sleep tracking and has built one of the largest databases of sleep over the past nine years with more than 7.5 billion nights tracked. The Fitbit Charge 3 improves on the sleep tracking offered by the Fitbit Charge 2.

The Fitbit Charge 3 allows users to track their menstrual cycles by using the Fitbit app to log their period and ovulation, record symptoms and compare cycle trends over time.

The Fitbit Charge 3 has improved its heart rate algorithms by 10 to 20 per cent in running and cycling conditions. This, along with the SpO2 sensor, will help track new health indicators like sleep apnea.

Sleep disturbance tracking

The Fitbit Charge 3 Special Edition comes with an array of features, including sleep tracking. Fitbit has been offering sleep tracking for many years and has built one of the largest databases of sleep, with over 7.5 billion nights tracked. The Charge 3 model has improved sleep tracking from the Charge 2, with the addition of a relative SpO2 sensor, which allows for the potential to estimate changes in blood oxygen levels and help track new health indicators, like sleep apnea.

The Fitbit Charge 3 Special Edition will track your sleep quality and disturbances by utilizing the SpO2 sensor. This will help to track sleep disturbances and periods of restlessness, as well as how long it takes you to fall asleep and how long you are actually asleep for. The Fitbit Charge 3 will give you a glimpse into your night with details on REM, light, and deep sleep.

The Special Edition also comes with Fitbit Pay, an extra black classic band, and, in the Asia-Pacific region, built-in contactless payments.

Sleep insights

The Fitbit Charge 3 Special Edition tracks your sleep patterns using a SpO2 sensor. This sensor has the potential to estimate changes in your blood oxygen levels and help track new health indicators, like sleep apnea. Fitbit has also introduced a beta version of its "Sleep Score" feature, which will track your sleep quality.

The Fitbit Charge 3 Special Edition provides insights into your sleep by tracking your sleep patterns and measuring your sleep quality. It tracks your sleep patterns by monitoring your movements throughout the night. This allows the device to track periods of restlessness, how long it takes you to fall asleep, and how long you are actually asleep.

The Fitbit Charge 3 Special Edition also measures your sleep quality by tracking your heart rate while you sleep. This data can be used to determine if you were particularly stressed during a certain period, for example. The device's heart rate algorithms have been improved for greater accuracy during exercise, providing a better measure of calorie burn and resting heart rate than previous Fitbit devices.

In addition to tracking your sleep, the Fitbit Charge 3 Special Edition also offers female health tracking, allowing you to gain a deeper understanding of your menstrual cycle by logging your period and ovulation, recording symptoms, and comparing cycle trends over time.

Sleep apnea tracking

The Fitbit Charge 3 Special Edition is a lightweight and affordable fitness tracker that can track your sleep. It comes with an array of bands and colours to choose from. It has a swim-proof design and a touchscreen display. The Fitbit Charge 3 Special Edition also has a longer battery life of up to 7 days, a 40% larger usable display area, and is 40% brighter than its predecessor, the Fitbit Charge 2.

The Special Edition of the Fitbit Charge 3 also comes with Fitbit Pay in the US, UK, and Europe, as well as NFC/contactless payments. In the Asia-Pacific region, all units include contactless payments built-in.

The Fitbit Charge 3 Special Edition also has a Sleep Score beta (SpO2) feature that can detect sleep disturbances, which may indicate health issues such as allergies, asthma, or sleep apnea. This feature is part of Fitbit's goal of developing FDA-regulated software for sleep and heart conditions. The SpO2 sensor in the Fitbit Charge 3 can track breathing disruptions and changes in blood oxygen levels, which can be indicators of sleep apnea. Fitbit will also be able to track sleep quality through its Sleep Score beta dashboard, which will provide insights on sleep quality that users can discuss with medical professionals.

Sleep score

The Fitbit Charge 3 Special Edition comes with sleep tracking capabilities. It provides details on REM, light, and deep sleep. Fitbit is also launching a beta version of a "Sleep Score" feature, which will be available through a dashboard. This Sleep Score will track sleep quality and will utilise the SpO2 sensor found in the Charge 3 to track SpO2.

The Sleep Score in the Fitbit app provides insight into your sleep quality. It is calculated based on your heart rate, the time spent awake or restless, and your sleep stages. Your overall score is the sum of your individual scores for time asleep, deep and REM sleep, and restoration, for a total score of up to 100. The restoration component of the score is based on your sleeping and resting heart rates and how much time you spent tossing and turning. A higher restoration score is achieved when your sleeping heart rate is lower than your daytime resting heart rate.

To check your sleep score, go to the Today tab in the Fitbit app and tap the Sleep duration tile. You can also review stats for previous days by tapping the arrow icons to move forward or backward. On certain devices, you can also check your sleep score directly from your wrist. It is important to note that your device needs to track sleep stages to determine your sleep score, and it may take a few minutes for the score to appear.

Some users have reported issues with their Fitbit devices not displaying their sleep scores. This could be due to various factors, such as the device not tracking sleep stages, the Fitbit app not being updated to the latest version, or irregularities in the user's resting and sleeping heart rate.
