The present invention relates to a device, system and method for determining a stress level, in particular for determining a psychogenic stress level of a user. The device comprises an interface (11) configured to obtain a skin conductance signal trace (22) of the user; a processing unit (12) configured to process the obtained skin conductance signal trace by: identifying a plurality of skin conductance peaks (50) in the skin conductance signal trace; determining, for each of said skin conductance peaks, a normalized parameter (58) of said skin conductance peak, normalized based on a skin conductance value (52, 53) of the respective skin conductance peak (50); and determining a psychogenic stress level (68) of the user based on said normalized parameters of said skin conductance peaks. The invention further relates to a corresponding wearable device (30) comprising such a device (10).
