To casual observers of either military service or the practice of yoga, the path from Oorah to Om may not seem obvious. But the intersection of yogi and veteran is natural if unexpected. Many members of the military now often include yoga ... as an element of their workout routine, and veterans turn to the practice for therapeutic applications. The Department of Veterans Affairs has successfully used yoga to help treat opioid addiction and post-traumatic stress. A lot of vets have post-traumatic stress, said Thierry Chiapello, who served in the Marines and now teaches yoga at the National Defense University in Washington. By lengthening the exhalation of breath, this gets people out of those fight-or-flight instincts that drain you, he continued, putting them in a mode of rest and recovery that definitely is associated with less aggressive behaviors. Christian Allaire experiences the service-driven life of yoga through his work for the Veterans Yoga Project, which provides yoga to roughly 1,000 veterans and their families per week as well as trains prospective teachers. We will have four or five people in a conference room at a V.A., he said. There might be an Iraq war vet in his 20s, a Korean War vet in his 80s, some can barely move, some may be missing limbs and the teachers job is to create space. Maybe all they can do is raise their hands above their heads, but we are creating a ritual.
