Heart rate variability (HRV)
Nervous system: Examination stress load and adaptability
The body regulates the frequency of the heart rhythm: physical or mental stress increase the heart rate, which usually goes back with relief and relaxation. Even at rest spontaneous changes in the time interval between two heartbeats occur.
This shows a higher adaptability to stress in a greater variability of the heart rate. Under chronic stress, however, both are increasingly limited because of the ever-high tension and therefore reduced.
With a sensor, the pulse is measured on the earlobe or on a fingertip and thus your heart rate. From this, the meter determines the Heart Rate Variability (HRV), which results in the change in your heart rhythm over time. The pattern of HRV produced in this way is influenced by our emotions: Frustration, fear or anger make the rhythm of the heart become irregular or chaotic. As a result, it is very easy to see how high your current level of stress and fatigue is.
Stabilization of the nervous system
Special breathing and focusing exercises help you to influence emotion-processing areas of the brain that establish a regular rhythm of heart rate variability. Thus, the stress burden is reduced and the adaptability of the autonomic nervous system improved.
