1. A method for monitoring a user's stress and for interrupting a stress episode, the method comprising:
determining a stress level threshold for the user, the stress level threshold indicating a stress level at which the user is experiencing a stress episode;
receiving a plurality of sensor readings from a wearable device worn by the user and determining a stress level of the user based on the plurality of sensor readings;
comparing the stress level to the stress level threshold; and
if the stress level exceeds the stress level threshold, initiating an intervention protocol at the wearable device to alert the user and interrupt the stress episode, the intervention protocol comprising haptic feedback at the wearable device;
wherein the stress level threshold is learned upon receiving at least a certain amount of sensor readings from the wearable device and is based on a specified percentile of historical stress levels for the user.
