In this book, medicine and the art of nasal breathing will be brought together. You will learn about the main concepts of nasal breathing. From a scientific perspective, the so called medical side, I present an informative, practical and thought provoking read for the general public, the curious and those interested in nasal breathing and other specifics about the functioning of the nose. These elements will also be fundamental for practitioners of yoga and meditation or mindfulness, ex-panding their general knowledge at different levels of practice.

The book's focus on the nose is an essential step in improving our understanding of other organs involved in meditation and yoga.

The chapters are presented as pairs, or dyads-the meeting of two complementary principles, such as yin and yang. First I introduce the scientific side and then I start to consider the art of yoga and mindfulness meditation.

In a playful way, I chose to name the parts of the chapters as INSPIRING and EXPIRING.

INHALE: You will explore all the main medical concepts of nose breathing scientifically.

EXHALE: The theme will have its corollary presented in meditation or yoga.

In some chapters, I pose broader questions about the elements covered, which offer something EXTRA for you to reflect on.

We know that breathing is simple and irreplaceable. For a long time, I believed, like many people, that the exceptional consisted of marveling at the rare. In reality, the exceptional is the ability to be interested in, appreciate and marvel at the simple. Breathing is so common that it goes unnoticed in everyday life.

A book about this universe, seen from a scientific perspective, can help you to make important reflections.

This book is not intended to make you an expert doctor or a yoga or meditation teacher. It describes the main medical concepts about the nasal cavities, in a scientific way, to facilitate their use in nasal breathing.

Enjoy !
