Is oxygen the new ayahuasca?  Kate Spicer reports on the breathwork revolution being used like psychedelic drugs

Fearne Cotton has used breathwork to manage anxiety, and describes it as “magic that can be created with breathing in a certain way”.  In her book Calm she dedicates an entire chapter to her experience with the Transformational Breath teacher Rebecca Dennis.

Dennis is the author of And Breathe, a book about conscious breathing that charts some of the many breathing styles out there.  Her three-hour workshops aim to get people breathing like a toddler, “opening up the respiratory tract”.  What inevitably follows is, she says, “digging in the subconscious, releasing suppressed feelings that are held on to in the body and the head.  Grief, pain, trauma, it helps release it.”
