Systems and methods for receiving galvanic skin response data from a galvanic skin response sensor that includes multiple electrodes fastened to a hand of a human; monitoring the galvanic skin response data to determine a time for initiating a Blood Pressure (BP) measurement using a blood pressure measurement cuff worn by the human (e.g., in a continuous or on-demand BP measurement mode); at the determined time, initiating the blood pressure measurement using the blood pressure measurement cuff; receiving blood pressure data for the human that results from the blood pressure measurement; and storing a blood pressure value that is based on the blood pressure data.
