Huawei Sleep is a feature on Huawei wearable devices that can monitor and track your sleep. The device can automatically record your sleep duration and identify what type of sleep you are getting, whether that be deep sleep, light sleep, REM sleep, or if you are awake. The feature can be manually or automatically enabled when the watch detects that you are asleep. Huawei TruSleep™ technology uses the PPG signals from Huawei's heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm to track sleep.

Sleep tracking capabilities
Huawei's sleep tracking capabilities are enabled through its TruSleep technology. This technology is based on PPG signals from Huawei's heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm. The CPC algorithm calculates sleep stages and respiratory quality based on continuous single-lead ECG signals. The close correlation between ECG and breathing is enhanced when the user is in deep sleep and can vary depending on whether the user is awake, sleeping lightly, or suffering from a health ailment.
Huawei's wearables, such as watches and bands, are equipped with TruSleep technology to identify motion features, classify motion levels, and incorporate heart rate fluctuations to track the user's sleep data. This includes sleep time, wake-up time, and sleep structure, which are used to generate sleep scores and tips for the user. The sleep tracking period is from 20:00 of the current day to 20:00 of the next day. Any sleep between 20:00 and 00:00 of the current day is recorded as sleep for the next day. Sleep for less than 3 hours is considered a nap, which does not support sleep structure analysis.
The device can also automatically detect whether the user is in deep sleep, light sleep, REM sleep, or awake. Users can enable either Auto or Scheduled sleep tracking. When Auto is enabled, the device will automatically enter and exit Sleep mode based on the user's sleep status. In Sleep mode, the device will not ring or vibrate for incoming calls and notifications, except when an alarm is set. The 'Raise to wake' feature will also be disabled. When Scheduled is enabled, the device will enter and exit Sleep mode according to the user's schedule.
Huawei's sleep tracking technology is based on detecting physiological indicators such as electroencephalograms, electrocardiograms, electromyography, breathing, and SpO2 to evaluate sleep quality and status. This data can be used by doctors to interpret results and determine relevant sleep issues and their severity. Huawei's wearables provide an affordable and less invasive alternative to traditional polysomnography (PSG) sleep tracking methods used in hospitals, which can be expensive and may not accurately represent real-world sleep patterns.

Sleep mode
To access Sleep mode settings, enter the device app list, select Sleep, swipe up to access the More screen, and touch Sleep mode or Settings. Here, you can choose between Auto and Scheduled options. Auto is enabled by default, and the device will automatically enter/exit Sleep mode based on your sleep status. With Scheduled enabled, you can set specific times for the device to enter and exit Sleep mode.
Huawei's sleep tracking technology, known as Huawei TruSleep™, uses PPG signals from heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm to track sleep. This data, along with motion detection, allows the device to identify sleep patterns, track sleep duration, and provide sleep analysis and tips. Huawei TruSleep™ is enabled by default, and disabling it will result in the unavailability of sleep data and analysis.

The sleep tracking period is from 20:00 of the current day to 20:00 of the next day. Any sleep generated from 20:00 to 00:00 of the current day is recorded as the next day's sleep. Sleep duration of less than 3 hours is counted as a nap, which does not support sleep structure analysis.
Sleep mode is disabled by default on Huawei wearables. When enabled, the device will not ring or vibrate for incoming calls and notifications (except alarms). The 'Raise to wake' feature will also be disabled. Sleep mode can be manually enabled or automatically enabled when the device detects that the user is asleep.

Sleep issues
Huawei's sleep tracking technology offers a more affordable and less invasive alternative. It uses PPG signals from heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm to track sleep. CPC calculates sleep stages and respiratory quality based on continuous single-lead ECG signals, which are closely correlated with breathing patterns, especially during deep sleep.
Huawei's wearables can identify different sleep stages, including deep sleep, light sleep, REM sleep, and awake.

Frequently asked questions
Huawei TruSleep™ sleep tracking technology uses the PPG signals from Huawei's heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm to track sleep. The technology can identify what type of sleep you are experiencing, whether that be deep sleep, light sleep, REM sleep, or awake, and it can also track your sleep duration.
To enable Sleep mode, swipe down on the watch face screen and touch Sleep mode. Sleep mode can be manually enabled or automatically enabled when the watch detects that you are asleep.
PSG is a method used in hospitals to track sleep. It involves patients sleeping in a specific sleep-tracking room with multiple conductor trace lines connected to their body. Huawei Sleep is far less invasive and expensive, as it uses smart wearables to detect physiological indicators such as electroencephalograms, electrocardiograms, electromyography, breathing, and SpO2 to evaluate sleep quality.
