The purpose of training your breath is to create a stronger and more stable nervous system. Since your breath influences your system to the smallest nerve fibres to all organs, your hormone production will produce “happy hormones”, like dopamine or serotonin, providing feelings of well-being and satisfaction. Controlled breathing is an effective tool to control and decrease stress levels. Mind and body work together connected by the breath. When the rhythm of the breath is reduced, so is the blood pressure and the nervous system. As a consequence, the rhythm of your brain and of your mind automatically slows down too.Brain, Heart and Lungs. Once all three are synchronised, the machinery of your body starts getting in balance.
