A method for measuring stress based on the heart rate (HR), the heart rate variability (HRV), and the activity level of a user includes recording the HR, the HRV, and the activity level of a user at various times during the day. Thereafter, the three values are correlated to arrive at a stress level of the user. The stress level is estimated based on a predetermined set of algorithms and analysis methods. The physical disposition and the activity levels of the user are automatically detected and the vital parameters, i.e., the HR and the HRV recorded at times that are deemed fit for conducting orthostatic tests.
