Abstract: A psychological stress estimation method includes obtaining a physiological signal of a user corresponding to a current moment, determining a first stress indicator of the user based on the current moment and a cyclic stress model of the user, determining a second stress indicator of the user based on the physiological signal of the user corresponding to the current moment and an instantaneous stress model of the user, where the physiological signal is an input of the instantaneous stress model, and determining the current stress indicator of the user based on the first stress indicator and the second stress indicator.

Abstract: A psychological pressure evaluation method includes obtaining a physiological parameter measurement value of a user, determining a psychological pressure evaluation model of the user based on a physiological parameter reference value of the user and a common psychological pressure evaluation model, where the common psychological pressure evaluation model reflects a change relationship between a psychological pressure value change amount and a physiological parameter value change amount, and determining a psychological pressure evaluation result of the user based on the physiological parameter measurement value of the user and the psychological pressure evaluation model of the user.
