What would it look like if we could measure stress and emotions?
If increased heart rate isn’t necessarily a sign of increased stress, what is?
These are questions I wondered about during my PhD research, and the answer does lie in the heart, specifically in heart rate variability (HRV).
Your heart doesn’t beat like a metronome. Between each beat, the interval shifts—sometimes shorter, sometimes longer—and that variation, measured in milliseconds, is a powerful and not-yet-well-understood signal your body sends about your psychological well-being.
Millions of people already see their HRV score on wearable devices. Yet many may not know what it means for their mental health. Let’s investigate the relationship between HRV and well-being in the context of positive psychology.
