Among the proven effects of this ancient practice, we find heightened concentration, calmness and mindfulness. This happens as Pranayama activates the parasympathetic system which works wonders in counterbalancing the body’s neurological response to stress, commonly known as the "Fight or Flight" response.
Furthermore, the way we breathe is inherently linked to our mental state. While emotions can impact our breathing, the opposite is also true: bringing mindfulness to our breathing patterns can help you gain control over your mood. This is what your yoga instructor means when they say something like “breathe into the pose."
