The Huawei Band 4 can identify different sleep stages, such as deep sleep, light sleep, REM sleep, and awakening. It does this by using a multi-modal fusion algorithm model that maps sleep and body movements, heart rate, and heart rate variability (HRV). The device also takes into account signals from moving transports, such as airplanes, high-speed railways, and cars, which may interfere with sleep status identification.

In addition to sleep stage identification, the Huawei Band 4 also focuses on respiratory quality. It does this by using the Cardiopulmonary Coupling (CPC) algorithm, which was proposed by a research team at Harvard University in 2005. CPC calculates sleep stages and respiratory quality based on continuous single-lead ECG signals, which are enhanced during deep sleep.

By combining CPC with ACC and PPG data, the Huawei Band 4 can provide insights into the user's respiratory quality during sleep. This includes information on breathing patterns and any potential sleep-related health ailments. Overall, the Huawei Band 4 provides comprehensive sleep tracking and analysis, offering users valuable insights into their sleep habits and quality.

It monitors sleep duration and body movement

The Huawei Band 4 uses TruSleep™ 3.0 technology to monitor sleep duration and body movement. This technology uses PPG signals from Huawei's heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm to track sleep. The CPC algorithm calculates sleep stages and respiratory quality based on continuous ECG signals, which have a close correlation with breathing patterns during sleep. By combining ACC and PPG data, TruSleep™ 3.0 can identify motion features, classify the user's motion levels, and incorporate heart rate fluctuations to accurately track sleep duration and body movement.

The device should be worn snugly on the wrist, with the screen facing upward, to ensure accurate sleep tracking. Signals from moving transports, such as airplanes, high-speed railways, and cars, may interfere with the device's sleep status identification, resulting in inaccurate sleep data. Therefore, it is important to ensure that the device is worn correctly and securely.

Huawei's TruSleep™ technology provides insights into five major sleep issues: difficulty falling asleep, frequent interruptions during sleep, insufficient sleep, irregular sleep schedule, and poor sleep quality. It offers comprehensive sleep solutions, including basic perception, evaluation, screening, and high-level tips to address these sleep issues. The sleep tracking period is set from 8:00 PM of the current day to 8:00 PM of the next day, with any sleep before midnight recorded as sleep for the next day.

The Huawei Band 4, through its TruSleep™ technology, aims to provide users with detailed sleep tracking and analysis, helping them understand and improve their sleep patterns. By monitoring sleep duration and body movement, the device can provide insights into sleep habits and quality, contributing to overall health and well-being.

It uses heart rate detection technology

The Huawei Band 4 uses heart rate detection technology to track your sleep. This technology is called Huawei TruSleep™ and it works by using PPG signals from the heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm. CPC calculates sleep stages and respiratory quality based on continuous single-lead ECG signals. There is a close correlation between ECG and breathing, which is enhanced when you are in deep sleep and can vary depending on whether you are awake, sleeping lightly, or suffering from a health issue.

The Huawei Band 4 also identifies motion features, classifies the user's motion levels, and incorporates heart rate fluctuations to track the user's sleep data, such as sleep time, wake-up time, and sleep structure. It is important to wear the device correctly for accurate readings. The device should be worn with the screen facing upward and should fit snugly on your wrist, with the monitoring area attached securely to your wrist and the fit comfortable.

The Huawei Band 4 can also be set up to automatically track your sleep. When Sleep mode is enabled, the device won't ring or vibrate for incoming calls and notifications (except for alarms), and the Raise to wake feature will be disabled. You can also set a sleep schedule by selecting the days and setting a bedtime and wake-up time.

The sleep tracking period is from 20:00 of the current day to 20:00 of the next day. Any sleep from 20:00 to 00:00 of the current day is recorded as the next day's sleep. You can view your sleep score, staging chart, and sleep details on the device or in the Huawei Health app, where you can view your sleep data by the day, week, month, or year.
