Pranayama: — Connection of breath and body, some scientific research.

Pranayama in an integral part of Yogic sciences. Usually the word Pranayama is used the context of manipulation of breath. But in the tradition of Yoga, Pranayama has a great amount of depth and breadth, it’s various techniques include several subtle elements apart from the simple breathing activity. The word Pranayama is a Sanskrit word, combination of two terms ‘Prana’ (breathing activity) and ‘Ayama’ (conscious manipulation). In Patanjali’s Yoga Sutra, Pranayama is referred to as the manipulation of breathing patterns, ranging from deep and prolonged to gentle and subtle.

The practical aspect of Pranayama from a physiological point of view is intended to influence the functions of the body and mind. While modern science adopts a objective and reductionist approach to understanding concepts, ancient sciences seem to use a subjective approach. From a Yogic point of view, the body and mind are not separate entities, they are considered to be interdependent, and two different aspects of one entity. So the essence of Pranayama then is clearing the physical and emotional obstacles in our body and lubricating the flow of “prana” — life energy. The way that one moves, thinks, acts and especially breathes contributes to the flow and vitality of our lives. For example if one is angry, they might breathe fire quite literally. While at rest, the breath slows down and gets deeper.

Let’s try and understand what modern day science and objective methods of enquiry find from the study of Pranamaya techniques.

There are arrays of articles and scientific research papers quoting the benefits of yoga and pranayama, for this article the primary source is from :-
