## What is Coherence?

Cardiac coherence is based on breathing exercises to slow down our heart rate, which tends to get carried away at the slightest emotional upheaval.

By acting in this way on his heart, it is possible to manage his emotional state and improve his physical and mental well-being (less stress, better sleep, better concentration, etc.).

The benefits of heart coherence

Practicing cardiac coherence has many benefits, both short-term and long-term.

Immediate effects :
- Increased amplitude of heart variability
- Appeasement

Effects on an average of four hours:
- Decrease in cortisol, the main defense hormone secreted during stress.
- Increase in DHEA, the youth hormone that slows aging.
- Increase in salivary IgA which participate in immune defense.
- Increase in oxytocin, a neurotransmitter that promotes attachment (also called the "love hormone").
- Increase in the atrial natriuretic factor, a hormone secreted by the heart and which acts on high blood pressure.
- Increase in alpha waves which promote memory, learning 

Long-term effects (after ten days):
- Decrease in high blood pressure
- Reduced cardiovascular risk
- Sugar level regulation
- Reduced abdominal perimeter
- Better recovery
- Improved concentration and memorization
- Reduction in attention and hyperactivity disorders
- Improved pain tolerance
- Improvement of asthmatic disease
- Improvement of inflammatory diseases
