The invention discloses a TV (television) system based physiological index monitoring system and method. The system comprises a smart TV, a remote control unit, a cloud server, a proximity sensor, a fingerprint identification sensor, a heart rate sensor, a force sensor, a non-invasive blood glucose detection device, a temperature sensor, a GPRS (general packet radio service) short message communication device, a voice of internet phone, a heart rate abnormity warning device, a blood glucose abnormity warning device, a body temperature abnormity warning device and a grip strength abnormity warning device, wherein APP software is embedded in a smart TV chip. The system has the beneficial effects that the remote control unit and the APP software are connected with the cloud server to send the data acquired in real time to the cloud server to be stored, thus solving the problem that various physiological indexes can not be tracked for a long time; and the remote control unit serves as a carrier of a measuring instrument, so that the measuring instrument has various detection items and even detects the harmful substances such as formaldehyde in home environments, thus solving the technical problem of singleness of the detection items.
