Key result
HRV tone-entropy distance inversely correlates with life satisfaction and flourishing, suggesting utility as a well-being index.
Why the study?
Well-being is recognized as vital for mental health, but its relationship to heart rate variability, particularly tone and entropy, remains unclear.
Does HRV tone-entropy distance correlate with self-reported well-being in office workers?
Observational (n=149)
Does HRV tone-entropy distance correlate with self-reported well-being in office workers?
HRV tone-entropy distance measured via PC cameras shows a small but significant correlation with self-reported well-being in office workers.
Should not yet change practice for well-being assessment; leaves open hypothesis-generating role for tone-entropy as life satisfaction marker.
OBJECTIVE: Well-being is increasingly recognized as vital for mental health, yet its relationship to heart rate variability (HRV)-particularly tone and entropy-remains unclear. We proposed using HRV tone-entropy distance to quantify worker well-being in real-world settings. METHODS: Pulse waves were measured using PC cameras in the workplace. Well-being was assessed using the Satisfaction with Life Scale (SWLS), the Positive and Negative Affect Schedule (PANAS), and the Flourishing Scale (FS). Correlations between these scores and tone-entropy distance were examined. RESULTS: Among 149 participants, significant, though small, correlations were observed between tone-entropy distance and SWLS and FS scores (r = -0.25, -0.30, respectively). A trend-level correlation was observed for PANAS positive and negative emotion. Some conventional HRV distances also showed significant correlations, but these were numerically smaller. CONCLUSIONS: Tone-entropy distance may serve as a quantitative index of well-being.

Koshi et al. (2026) conducted an observational in Well-being in office workers (n=149). HRV tone-entropy distance was evaluated on Correlations between well-being scores (SWLS, PANAS, FS) and tone-entropy distance (r = -0.25 (SWLS), r = -0.30 (FS)). HRV tone-entropy distance showed significant correlations with Satisfaction with Life Scale (r = -0.25) and Flourishing Scale (r = -0.30) scores, suggesting its utility as an index of well-being.
