摘要

Objective: Human salivary cortisol is a major possible physiological index for the evaluation of mental stresses and photoplethysmogram appearance is sensitive to stress-induced haemodynamic changes. The purpose of this experiment was to assess these features in laboratory settings under both stressful and non stressful situations. Methods: The effect of a mental stress test was assessed in 55 healthy young adults using salivary cortisol. Blood pressure and heart rate as well as photoplethysmogram appearance were measured as indices of mental stress-induced changes. Results: The results of medical examination showed that salivary cortisol levels were significantly elevated (P0.05) was observed after viewing neutral pictures of it respectively. Significant increase of two parameters derived from PPG signals was observed (P0.05) after viewing neutral pictures either. A significant mean heart rate drop (P
