The measurement of heart rate variability (HRV) is the precise, scientific analysis of your individual stress factors and your regenerative capacity.
Our vegetative nervous system consists of two parts: the stress and performance aka “fight-or-flight” nervous system (the sympathetic nervous system) and the resting and regenerative nervous system (the parasympathetic nervous system).
As always in nature, these two parts must maintain a balance. However, in our modern way of life, the stress nervous system predominates – often considerably – and permanently overloads the body with stress hormones (adrenaline, cortisol, noradrenaline), leaving the regenerative nervous system (with the regeneration hormones melatonin and progesterone) unable to provide sufficient balance.
With the help of HRV, we measure how well your body is able to preserve the necessary balance between the sympathetic and parasympathetic nervous systems, which is essential for your long-term health.
