Summary
A systematic review confirms HRV is a valid tool for monitoring stress and allostatic load in first responders and tactical operators, helping manage acute fatigue that can impair performance and cause chronic health issues.
Methods
Systematic review of HRV studies in first responders
Key Findings
- HRV reflects cumulative stress in tactical personnel
- Work stress affects HRV and may predict heart disease
- Over 50% of firefighter deaths linked to stress/exhaustion
- Chronic fatigue reduces HRV in first responders
- HRV monitoring can guide recovery interventions
Limitations
Heterogeneous study designs and populations
What This Means for You
If you're a first responder, regular HRV monitoring can help track cumulative stress before it leads to burnout or health problems. Declining trends warrant attention to recovery and stress management.
