A non-invasive health monitoring system comprises a wearable central sensor and at least one wearable remote sensor in wireless communication, a portable device readily accessible to the user, and a cloud platform. Each sensor collects batches of data indicative of one or more physiological parameters of the user at a physiological parameter-specific frequency, for a pre-defined time window. The central sensor receives and processes the measured data from each sensor, and stores processed data in a memory within the central sensor. The portable device comprises a receiver wirelessly receiving the processed data and instructions from the central sensor; a processor running a mobile application handling the processed data and instructions; and a transmitter. The cloud platform receives the processed data from the transmitter; analyzes the received processed data; and transmits the results to at least one of the portable device and an authorized healthcare entity.
