Operating a hearing device to assist the user in engaging in a healthy living style

A method of operating a hearing device configured to be worn at an ear of a user to assist the user in engaging in a healthy living style, the method comprising:

• receiving, from an input transducer included in the hearing device, an input audio signal indicative of a sound detected in an environment of the user;
• processing the input audio signal;
• outputting, by an output transducer included in the hearing device, an output audio signal based on the processed input audio signal so as to stimulate the user's hearing;
• receiving sensor data including physiological data indicative of a physiological property of the user;
• determining, based on the physiological data, whether the input audio signal comprises an audio feature matching a sound pattern characteristic of sound emitted by a subject suitable to impact at least one of a physical health or a mental health of the user;
• and, when the input audio signal comprises the audio feature,
• modifying, during the processing of the input audio signal, the audio feature in the input audio signal so as to increase or decrease, during the outputting of the output audio signal, an awareness of the user of a presence of the subject in the environment,
• wherein the physiological data is received from at least one of:
• an optical sensor configured to emit light at a wavelength absorbable by an analyte contained in blood of the user;
• a bioelectric sensor comprising at least one electrode configured to detect a bioelectric signal from the user's body;
• or
• a body temperature sensor configured to detect a temperature of the user's body.
