Your adaptability to stress is determined by your heart rate variability (HRV). The HRV is measured by the variation in the beat-to-beat time interval of your heart.
A good balance of sympathetic and parasympathetic activity in your nervous system makes for a high HRV. The latter is key for your stress resilience and also a marker for your overall fitness.
Emotional or physical challenges impact your HRV directly – and vice-versa. A lower resting HRV has been linked to multiple diseases, stress, anxiety, depression, reduced immune response and all-cause mortality. A high HRV improves your quality of life in nearly every aspect.
Your HRV Can Be Improved in Various Ways
- Physical training
- Mindful practices
However, one of the easiest practices to get better at stress is biofeedback coupled with slow breathing. Clinical studies have shown, that 6–10 weekly sessions of HRV biofeedback training and daily practice reduce numerous mental and physical ailments.
