The heart is influenced by the opposing parts of our autonomic nervous system, resulting in an increase and decrease in heart rate. This phenomenon is known as heart rate variability.
When this happens smoothly, the state is known as cardiac coherence; when haphazardly, cardiac chaos.
Cardiac chaos will result in a dampening of our immune system and negative physiological changes such as an increase in blood pressure.
Coherence states help to reduce stress related symptoms and improve our ability to:
- Think logically.
- Work efficiently.
- Perform physically.
- Enhance immunity.
- Decrease stress levels and the stress hormone cortisol
- Increase levels of the hormone dihydroepiandosterone(DHEA). (Higher ratios of DHEA to cortisol have positive implications for health and age related decline)
Techniques to maintain cardiac coherence are taught using a simple breath focused approach with visualisation and biofeedback. These can then be implemented to enhance physical and mental functioning.
The technique can be practised and used at any time, in any place, whether to relax or to prepare oneself for a stressful event.
Biofeedback devices can be utilised to monitor the effects of these techniques in real time.
