The Claim
Neuroimaging studies suggest that heart rate variability is associated with activity in the ventromedial prefrontal cortex, implying that heart rate variability may reflect the brain's ability to modulate autonomic responses to stress.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with higher heart rate variability tend to have more activity in a part of the brain that helps calm stress and fear, which might mean their body is better at handling stressful situations.
See the scientific wording
Neuroimaging studies suggest that heart rate variability is linked to activity in the ventromedial prefrontal cortex, a brain region involved in regulating threat perception and emotional responses, implying that HRV may reflect the brain’s ability to modulate autonomic responses to stress.
What the research says
1 studyStudy: Stress and Heart Rate Variability: A Meta-Analysis and Review of the Literature
This study says that scientists have found a connection between how your heart rate changes when you're stressed and a part of your brain that helps you handle fear and emotions — meaning your heart’s rhythm might show how well your brain is managing stress.
