Abstract: To objectively grasp a stress state of a user and to prevent a mental disorder of the user, the following steps are performed: acquiring, via a network, biogas information at multiple timings and time information corresponding to each of the multiple timings, wherein the biogas information represents a concentration of tetradecane of a user acquired by a sensor that detects tetradecane discharged from a skin surface of the user; obtaining reference information representing an upper limit of a normal range of the concentration of tetradecane per unit period of time, using a memory storing the reference information representing the upper limit of the normal range; determining a stress time period during which a concentration of the tetradecane of the user is more than the upper limit of the normal range, based on the acquired biological gas information; and outputting time period information indicating the determined stress time period to an information terminal of the user, to display the stress time period indicated by the time period information on a display of the information terminal.

Abstract: A method includes: acquiring, via a network, biogas information at multiple timings and time information corresponding to time at each of the multiple timings, wherein the biogas represents a concentration of 2-ethylhexanoic acid of a user acquired by a sensor that detects the 2-ethylhexanoic acid discharged from a skin surface of the user; obtaining reference information representing a lower limit of a normal range of 2-ethylhexanoic acid per unit period of time, using a memory storing the reference information representing the lower limit of the normal range; determining a stress time period during which a concentration of the 2-ethylhexanoic acid of the user is less than the lower limit of the normal range, based on the acquired biogas information; and outputting time period information indicating the determined stress time period 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 acetophenone of the user and is obtained by a sensor that detects acetophenone 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 acetophenone 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 acetophenone 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 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.
