Measuring psychosocial stress with heart rate variability-based methods in different health and age groups
2022
Abstract Objective. Autonomic nervous system function and thereby bodily stress and recovery reactions may be assessed by wearable devices measuring heart rate (HR) and its variability (HRV).
