Heart Rate Variability (HRV) Biofeedback

HRV (Heart Rate Variability) is the subtle variation of the time interval between heart beats.

So, if your heart rate is 60 beats per minute, it’s not actually beating once every second.  For example, within that minute there may be 0.9 seconds between two beats and 1.15 seconds between two others and other differences between each of the 60 beats. In the example, the difference of 0.25 seconds between the 0.9 seconds and the 1.15 seconds is the HRV.

HRV measures the autonomic nervous system or the balance between the sympathetic and the parasympathetic systems. 

So why HRV Biofeedback?

I teach self-awareness and self-regulation of the nervous system. Stress is not just biological. You must make changes behaviorally, relationally/socially and spiritually.

You can learn to use Heart Rate Variability to optimize your sleep, stress, recovery, performance and nervous system.

Since the autonomic nervous system organizes arousal in both body and brain, poor HRV - that is, a lack of fluctuation in heart rate in response to breathing - not only has a negative effect on thinking and feeling but also on how the body responds to stress. 

Optimal HRV

An optimal level of HRV (Heart Rate Variability) is associated with health and self-regulatory capacity, and adaptability or resilience.

How to increase HRV and improve wellbeing

During HRV biofeedback training, clients are taught how to improve their breathing using paced abdominal breathing between 4,5 – 7,5 bpm guided by a real-time display of heart rate and respiration. This is called breathing at your resonance frequency and consciously breathing just a few minutes sends signals of balance to our brain, telling us that we are ok, and brings us out from the part of the brain that makes us feel overwhelmed, into a state of calm.
