Standard deviation of pulse pressure measured using wearable devices improves the estimation of acute psychological stress.

ABSTRACT: Recent technical innovations have increased the use of physiological information as objective indices for stress measurement. Early detection of acute stress can minimize long-term stress burdens by aiding in the prevention and treatment of stress-related physical and mental health problems. The standard deviation of pulse pressure (SDPP) has recently emerged as an objective index for measuring stress. However, the causal relationship between acute stress and SDPP has not been verified, and it is unclear whether SDPP can detect stress responses that conventional indices cannot. This study investigated whether SDPP, measured using a wearable device, can be used as a stress assessment index to detect acute psychological stress and improve the accuracy of stress estimation in healthy particip
