Summary
HRV correlates with cognitive performance, particularly executive function, decision-making, and emotional regulation. Higher vagal tone supports better brain function across age groups.
Methods
Literature review of HRV and cognitive function studies
Key Findings
- Higher HRV associated with better executive function
- Vagal tone supports prefrontal cortex activity
- Low HRV linked to cognitive impairment and dementia risk
- Relationship holds across age groups
- Interventions improving HRV may support cognition
Limitations
Bidirectional relationship, causation unclear
What This Means for You
Maintaining healthy HRV may support brain health as you age. Activities that improve HRV (exercise, sleep, stress management) may also protect cognitive function.
