Abstract
Methods, systems, and devices for determining a sleep age metric of a user are described. The system may receive photoplethysmogram (PPG) data throughout a time interval including a plurality of sleep intervals during which the user is asleep, input the PPG data into a first machine learning model, and classify the PPG data into a plurality of sleep stages. The system may input one or more sleep features into a second machine learning model, and the second machine learning model may output a sleep age metric associated with a sleep health of the user relative to a chronological age of the user. In some cases, the system may transmit, to a user device, an instruction to cause a graphical user interface (GUI) to display an indication of the sleep age metric and an insight for a value of the sleep age metric.
