Techniques for measuring cumulative stress using wearable-based data

A system for measuring cumulative stress of a user over time, comprising:

• at least one processor;
• at least one memory coupled with the at least one processor;
• and
• instructions stored in the at least one memory and executable by the at least one processor to:
• acquire baseline physiological data from the user via a wearable device, the baseline physiological data comprising at least a pulse waveform associated with a heart rate of the user;
• determine a baseline stress level associated with the user based at least in part on the baseline physiological data, one or more user inputs received via a user device, or both;
• determine, based at least in part on variation in an interbeat interval (IBI) of the pulse waveform of the baseline physiological data, a first baseline heart rate variability (HRV) value of the user during periods that the user is awake, and a second baseline HRV value of the user during periods that the user is asleep;
• acquire additional physiological data from the user via the wearable device throughout a time interval that spans a plurality of days and a plurality of nights;
• determine, based at least in part on the additional physiological data, a first set of HRV values of the user during periods of the time interval that the user is awake, and a second set of HRV values of the user during periods of the time interval that the user is asleep;
• determine one or more stress scores associated with the user throughout periods of the time interval that the user is awake based at least in part on a first comparison of the first set of HRV values with the first baseline HRV value;
• determine one or more recovery scores associated with the user throughout periods of the time interval that the user is asleep based at least in part on a second comparison of the second set of HRV values with the second baseline HRV value;
• determine a cumulative stress level of the user throughout the time interval based at least in part on the one or more stress scores associated with periods of the time interval that the user is awake, and the one or more recovery scores associated with periods of the time interval that the user is asleep, wherein the cumulative stress level is based at least in part on the baseline stress level, and wherein the cumulative stress level is associated with a total amount of stress the user experienced throughout the time interval, a trend in a stress level of the user throughout the time interval, or both;
• and
• display, to the user via a graphical user interface (GUI) of the user device, a visual representation of the cumulative stress level.

A non-transitory computer-readable medium storing code for measuring cumulative stress of a user over time, the code comprising instructions executable by at least one processor to:
