Energy signature: a predictable pattern of mental and physical energy levels throughout the day that follows circadian and ultradian biological rhythms, characterized by distinct peak, trough, and recovery phases
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'energy signature' by identifying its genus (pattern of energy levels) and differentia (following circadian/ultradian rhythms, characterized by peak/trough/recovery phases). It distinguishes this from general energy levels by specifying the biological and temporal structure.
