Resonance Breathing (also called Heart Resonance Breathing) is breathing at a slow rate, usually four to seven breaths per minute. It’s basically another name for the Coherent Breathing method.
In the medical world, Resonance Breathing is often used for Heart Rate Variability (HRV) training, which means that your heart rate on inhale and exhale, when measured over a period of time, starts to become a smooth, harmonious set of “waves.” The “wave” is due to the fact that one’s heart rate naturally increases on inhaling, and decreases on exhaling.
One of the core ideas is that by controlling your breathing pattern and intentionally shifting to a positive emotion, such as appreciation, care, or compassion, your heart rate rhythms and breathing pattern become synchronized and create a healthier emotional and physical state.
Additionally, it’s thought that Resonance Breathing lowers stress, anxiety, and blood pressure, stimulates better sleep quality, and improves cognitive functions such as focus, attention, and concentration.
