Breathe to Flow
the science
All of our work is evidence-based and has solid studies behind it and we do our best to keep up with new studies on the science of breathing.
​
This section presents a carefully curated selection books, articles and studies that we find inspiration in and which we base our own methodology on.
Books
Breath - The New Science of a Lost Art
James Nestor (2020, Penguin Books)
A must-read if you want to dive deeper into breathing. Very well-researched book that gives an overview of the history of breathing.
Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head.
The Oxygen Advantage
by Patrick McKeown (2015, Piatkus)
A highly recommended book for those interested in how breathing applies to sports and movement in general. Very solid scientific background from one of the world's leading experts in breathing.
McKeown introduces readers to the "Oxygen Advantage," an innovative but complex breathing technique that purportedly improves overall health... McKeown's confident attitude should help his book appeal to a wide audience.

studies
The list below includes research that support our method with scientific background and studies. It's important to keep in mind that science is always in development and that no study holds the final truth. With that in mind, we try to only include well-documented science and to always be critical with the studies we base our work on.
​
This document includes references to many of the relevant studies I’ve found for breathing. With research, it's important to know that *lots* of published studies are overturned and found to be lacking or even wrong. Science is a work-in-progress forever - as is this document.
