Today, cardiac coherence practice encounters a great success amidst the public as well as health professionals.
First applied in the prevention of cardiovascular diseases, it is increasingly used in programs of stress and anxiety management as well as regulation of the emotional response.
The principle of cardiac coherence biofeedback is based on the hypothesis that the stimulation of the vagal system, translated by an increase of the heart rate variability, can help you, via regular practice, to improve your health status or your performances.
By reinforcing the self-regulating adaptability of our physiological system, especially facing the stressing solicitations of our daily lives, the cardiac coherence will ensure a greater flexibility to fight against somatic and psychological pathologies and will help our body maintain a better cardio-respiratory and mental balance.
Several teams worldwide have recently conducted clinical studies on the relevance of reinforcing the vagal tone by cardiac coherence practice. Scientific references have largely demonstrated benefits for:
- Decreasing anxiety and depression levels

The variability phenomenon is affected by several fluctuations caused by the subject or environmental stress factors. The values obtained must be interpreted as an indirect measure of the functioning of the autonomic nervous system, its main relevance resides in learning how to better modulate emotional reactions.
