Method and system for providing health management service

A method and a system for providing a healthcare service are provided to enable a user to receive the healthcare service by enabling the user to attach various kinds of sensors, which are miniaturized in an accessory type, for detecting/providing a biological signal of the user. Each biological signal measurement system(100-1 - 100-n) is attached the user, and wirelessly transmits the biological signal by including a plurality of sensors for detecting various kinds of biological signals. A healthcare server(400) provides a manual for the healthcare service registered by the user. A portable healthcare system(200) operates a service program for providing the registered healthcare service to the user, and provides the healthcare service based on the biological signal received from each biological signal measurement system and the manual received from the healthcare server. The sensors include at least one of a PPG(PhotoPlethysmorGram) sensor, a GSR(Galvanic Skin Reflex) sensor, an ECG(ElectorCardioGram) sensor, a skin temperature sensor, an EDA(ElectroDermal Activity) sensor, and an accelerometer.
