Abstract

Described herein are apparatuses and methods for measuring stress with a wearable device. In one apparatus, a wearable device includes a housing formed and shaped to affix to a user, a sensor integrated into the housing operable to engage a body of the user to take physiological measurements of the user over a threshold period of time to obtain physiological data, and a processing device coupled to the sensor. The processing device may be operable to receive, from the sensor, a first physiological data; receive, from the sensor, a second physiological data; determine a correlation between the first physiological data and the second physiological data; and determine a stress level of a bodily system of the user based on the correlation.
