Heart Rate variability (HRV)
The relationship between HRV and disease is extensively scientifically documented.
Google Scholar lists 16 400 articles about stress and “non-communicable diseases”, 17 500 articles about stress and respiratory diseases, 21 000 articles about stress and health effects, 56 000 articles about stress and heart disease, 290 000 articles about stress and diabetes, 483 000 articles about stress and cancer since 2013.
Research has shown a relationship between low HRV and worsening depression or anxiety. A low HRV is associated with increased risk of death and cardiovascular disease.
The use of resting heart rate and HRV is well established in sports and other high performance fields (9 000 articles since 2013). Still the scientific documentation related to health dwarfs HRV and sports.
Overskudd’s use of HRV
HRV is a noninvasive way to identify imbalances in the Autonomic Nervous System (ANS). Overskudd’s use of HRV aim’s to restore balances and personal dynamics to restore and build health, while building performance potential.
People who have a high HRV typically have greater cardiovascular fitness and are more resilient to stress. HRV provides personal feedback about your lifestyle and help motivate those who are considering taking steps toward a healthier life. It is fascinating to see how HRV changes as you incorporate more mindfulness, meditation, sleep, and especially physical activity into your life. You can track how your nervous system is reacting not only to the environment, but also to your emotions and thoughts.
Your personal dynamic is important
If a person’s system is in more of a fight-or-flight mode, the variation between subsequent heartbeats is low. If one is in a more relaxed state, the variation between beats is high. In other words, the healthier the ANS the faster you are able to switch gears, showing more resilience and flexibility.
