From a memory storing information including an upper limit of a normal range of the concentration of 2-phenoxyethanol 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 2-phenoxyethanol 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. ## Claims ### Claim 1 A method for providing information in an information processing system, the method comprising: acquiring, via a network, biological gas information representing a concentration of 2-phenoxyethanol of a user detected with a sensor for detecting 2-phenoxyethanol released from a skin surface of the user; obtaining reference information representing an upper limit of a normal range of the concentration of 2-phenoxyethanol per unit period of time, using a memory storing the reference information representing the upper limit of the normal range; and outputting information related to stress of the user to an information terminal after it is determined that a frequency with which the concentration of the 2-phenoxyethanol of the user per unit period of time is more than the upper limit of the normal range tends to increase, based on the biological gas information acquired in a pregnancy period of the user. ### Claim 2 (depends on 1) The method according to claim 1, wherein the information including the upper limit of the normal range of the concentration of 2-phenoxyethanol per the unit period is set for the user as individual information of the user, based on the biological gas information acquired in a predetermined period in an early stage of the pregnancy period of the user. ### Claim 3 (depends on 1) The method according to claim 1, wherein the information including the upper limit of the normal range of the concentration of 2-phenoxyethanol per unit period is used commonly to a plurality of users including the user. ### Claim 4 (depends on 1) The method in an information processing system according to claim 1, wherein when it is not determined that the frequency with which the concentration of the 2-phenoxyethanol of the user per unit period of time is more than the upper limit of the normal range tends to increase, the information related to stress of the user is not output to the information terminal. ### Claim 5 (depends on 1) The method according to claim 1, wherein the information terminal is a first information terminal of the user. ### Claim 6 (depends on 5) The method according to claim 5, wherein the information terminal is a second information terminal, of a consulting business operator other than the first information terminal of the user. ### Claim 7 (depends on 1) The method according to claim 1, wherein the information terminal is a first information terminal of the user, and the method further includes: acquiring first address information on the first information terminal and second address information on a consulting business operator from a memory storing the first address information and the second address information, when it is determined that the frequency that the concentration of 2-phenoxyethanol of the user per the unit period of time is more than the upper limit of the normal range of tends to increase; and outputting the information related to stress of the user to both of the first information terminal and a second information terminal of the consulting business operator, based on the first address information and the second address information, wherein the second information terminal of the consulting business operator is distinct form the first information terminal. ### Claim 8 (depends on 7) The method according to claim 7, wherein the information to be output to the first information terminal includes display information for allowing the user to select whether to accept contact of the consulting business operator with the user. ### Claim 9 (depends on 1) The method according to claim 1, wherein the information related to the stress of the user is used to call the user's attention to a need for reducing stress build up in the user. ### Claim 10 (depends on 1) The method according to claim 1, wherein the information related to the stress of the user indicates that the stress of the user is more than the predetermined normal range. ### Claim 11 (depends on 1) The method according to claim 1, wherein the sensor for detecting 2-phenoxyethanol is built in a device to be worn on the user. ### Claim 12 (depends on 1) The method according to claim 1, wherein the information processing system is configured to acquire the biological gas information along with a user ID of the user, and to output the information related to stress on the user to the information terminal associated with the user ID of the user. ### Claim 13 An information processing system comprising: a server device;
