Disclosed is a portable heart rate variability (HRV) based health monitoring system having an electromagnetic field (EMF) sensor built in. The health monitoring system comprises an input means having a plurality of sensors for measuring the electromagnetic field (EMF), the geomagnetic field, the heart rate, body temperature, etc., respectively, a microprocessor for receiving signals outputted from the input means to produce specific indexes using a previously stored calculation equation, and controlling the system, a spectrum analyzer for analyzing the level of exposure to the EMF and the geomagnetic field from the data values calculated by the microprocessor, and a display means for displaying the data values inputted through the microprocessor and the spectrum analyzer. |
