Method and device for synchronizing a physiological state of an individual to a state desired.

The invention relates to a method and an associated device for feeding an individual from an initial physiological state (EP0) to a final physiological state (EPF). The physiological state of the individual is defined by a set of physiological parameters (RP1A, RP1B, RP1C, RP1D, RP2A, RP2B, RP3A, RP3B, RP3C, ...) characteristics of one or more physiological rhythms of individual. The set of physiological parameters includes at least two physiological parameters from a value (RP1A), a variability (RP1B), amplitude variations (RP1C) and a periodicity of variations (RP1D) of a physiological rhythm (RP1) of 'individual.
