Abstract: In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of benzothiazole of the user and is obtained by a sensor that detects benzothiazole released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of benzothiazole per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of benzothiazole of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

Abstract: In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of tetradecane of the user and is obtained by a sensor that detects tetradecane released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of tetradecane per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of tetradecane of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.
