A health improvement system includes at least one sensor module, a computing module, an interaction module and a database module. The sensor module is configured for detecting at least one data selected from the group consisting of user behaviors, user activities, user physical data, user psychological data, and a combination thereof, so as to generate sensor data. The computing module is configured for computing the sensor data, for generating an evaluation result to evaluate an effect for at least one user's health, for converting the sensor data and the evaluation result to at least one internal parameter, and for changing a health condition representation according to the internal parameter. The interaction module is configured for outputting the health condition representation. The database module is configured for storing the user input parameters, the sensor data, the evaluation result, the internal parameters and the health condition representation.
