The LF/HF ratio in Heart Rate Variability (HRV) reflects the balance between your sympathetic and parasympathetic nervous systems. This ratio is a powerful indicator of your stress levels, recovery ability, and risk of cardiovascular conditions.
By measuring LF/HF daily with JBA.Ai—a software approved by the FDA as SaMD (Software as a Medical Device)—you can monitor your nervous system health quickly and conveniently through your phone. This enables proactive health management and helps prevent costly health complications.
What is LF/HF and Why is it Important?
The LF/HF ratio represents the relationship between two key branches of the autonomic nervous system:
- LF (Low Frequency): Reflects sympathetic nervous system activity—associated with stress, alertness, and the “fight or flight” response
- HF (High Frequency): Reflects parasympathetic nervous system activity—associated with relaxation, rest, and recovery
What the ratio tells you:
- A high LF/HF ratio may indicate chronic stress, elevated risk of cardiovascular diseases, hypertension, and reduced immunity
- A low LF/HF ratio may suggest physical exhaustion, burnout, or autonomic nervous system imbalance
Benefits of Measuring LF/HF Daily with JBA.Ai
Tracking your LF/HF ratio daily using JBA.Ai offers a wide range of benefits:
- Detect early signs of chronic stress to prevent heart disease and hypertension
- Evaluate your body’s ability to recover, helping to optimize sleep and overall energy
- Monitor how lifestyle changes (e.g., diet, workouts, relaxation techniques) impact your nervous system
- Support management of autonomic nervous system dysfunction for better cardiovascular and circulatory health
Save on Future Healthcare Costs
Neglecting LF/HF imbalances can lead to long-term stress-related illnesses and high medical expenses:
- Cardiovascular treatments: Chronic stress increases the risk of heart attacks, strokes, and hypertension—potentially costing thousands annually
- Mental health support: Stress-related anxiety and depression may require therapy and medication
- Post-illness rehabilitation: Autonomic dysfunction can lead to reduced quality of life and costly recovery programs
