> The new study from the University of Birmingham reveals a statistically significant reduction in HRV in response to grammatical violations. This reduction reflects the extent of the grammatical violations, suggesting that the more errors a person hears, the more regular their heartbeat becomes – a sign of stress.
Interesting that a more regular heartbeat is a sign of stress. Wonder why that is...
- Terr_ 3y agoAFAICT it's because your heart-rate comes from overlapping systems, and for whatever reason raising the influence of stress-triggered systems makes it more regular. (In the absence of other disorders.) Perhaps the ready-for-action regularity comes at a cost, and when everything is calm and safe there's no need for your body to incur that cost, it can afford a less-strict clock.
