Perceived mental stress during occupational work correlated inversely with differences in HRV parameters TINN (r=-0.73) and RMSSD (r=-0.60) obtained in the morning and during the workday.

Can heart rate variability parameters detect perceived mental stress during occupational work?
Differences in HRV parameters (TINN and RMSSD) from night to morning correlate inversely with perceived mental stress, suggesting their utility for stress detection.
Effect estimate: r=-0.73 (TINN), r=-0.60 (RMSSD)
In this study perceived mental stress during occupational work was compared to heart rate variability (HRV) using a traditional questionnaire and a novel wristop heart rate monitor with related software. The aim was to find HRV parameters useful for mental stress detection. We found the highest correlation between perceived mental stress with the differences between the values of triangular interpolation of rhythm-to-rhythm (RR) interval histogram (TINN) and the root mean square of differences of successive RR intervals (RMSSD) obtained in the morning and during the workday (r=-.73 and r=-.60, respectively). The analysis shows that as the RMSSD and TINN value differences increase from night to morning, the stress decreases.
Orsila et al. (Tue,) conducted a cross-sectional in Perceived mental stress. Wristop heart rate monitor vs. Traditional questionnaire was evaluated on Correlation between perceived mental stress and HRV parameters (r=-0.73 (TINN), r=-0.60 (RMSSD)). Perceived mental stress during occupational work correlated inversely with differences in HRV parameters TINN (r=-0.73) and RMSSD (r=-0.60) obtained in the morning and during the workday.
