Although breathwork is having a resurgence in the Western world, it has long been at the core of many spiritual and physical Eastern practices for hundreds of years.
Breathwork practices are most commonly recognised in the early Yogi/Buddhist philosophies and cultures. Pranayama, which in Sanskrit means the suspension of breath, originated in the 9th century through the Tibetan Buddhist monks and remains a major part of Tibetan Buddhist practice and awareness today.
Other breathing modalities that are well recognised include Systema (Russian), Taoist practice, Soma breath, Holotropic (Stan Groff), Wim Hoff, Transformational breathwork, Buteyko breathing, The Oxygen Advantage, and Breathwave. The last 3 of which I am certified in.
