Abstract
Methods, systems, and devices for measuring cumulative stress of a user are described. A system may determine a first and second baseline heart rate variability (HRV) values of the user during periods that the user is awake and asleep, respectively. The system may then acquire physiological data from the user throughout a time interval, and determine a first set of HRV values during periods that the user is awake, and a second set of HRV values during periods that the user is asleep. The system may then determine a cumulative stress level of the user based on comparisons between the first set of HRV values and the first baseline HRV value, and between the second set of HRV values and the second baseline HRV value, where the cumulative stress level is associated with a total amount and/or trend of the user's stress level experienced throughout the time interval.
