Abstract: Systems and methods for assessing and managing stress of a user is provided. The system includes a wearable device that can be worn by the user; the wearable device include a sensing device for generating at least one time-series signal by continuous sensing of light intensity of light signals. The time-series signal includes at least one continuous photoplethysmographic (PPG) signal having an LF and an HF component. The system also includes a stress assessment device to determine a stress level of the agent based on a processing of the PPG signal. The stress assessment device further includes a feedback device configured by the processor to provide a feedback including at least one remedial message to the agent based on the determined stress level of the agent.
