Measurement of Stress Using Heart Rate Variabilitty by Smart Phone Technology – A Study

Stress leads to various physical and mental diseases in people and there exists only a few methods to monitor the stress level in long term period. In this study heart rate variability (HRV) based stress measurement is conducted among different people. HRV value depends on how well SNS and PNS are balanced .Results indicate that higher the value of HRV means lower is the stress and vice versa. Stress Index is compared with the help of measuring the variations in NN intervals.HRV based stress measurement using Smartphone is simple and easy to monitor stress level in long term compared to the clinical measurements available in the laboratories.
