Abstract

The present invention relates to a device () for detecting a circadian phase shift of a user (). The device comprises: an interface for obtaining a skin conductance signal of the user () and sleep cycle information of the user (); a processing unit () for determining an internal clock wake-up time based on the obtained skin conductance signal () and an external clock wake-up time based on the obtained sleep cycle information; and an evaluation unit () for evaluating a circadian phase shift of the user () based on the internal clock wake-up time and the external clock wake-up time. The present invention further relates to a corresponding method as well as to a wearable system () for monitoring a circadian phase shift of a user ().
