New research offers hope for those suffering from post-traumatic stress disorder. Researchers there have shown that a breathing-based meditation practice called Sudarshan Kriya Yoga can be an effective treatment for PTSD.
One of the greatest casualties of war is its lasting effect on the minds of soldiers. This presents a daunting public health problem: More than 20 percent of veterans returning from the wars in Iraq and Afghanistan have post-traumatic stress disorder, according to a 2012 report by RAND Corp.
Individuals with PTSD suffer from intrusive memories, heightened anxiety, and personality changes. The hallmark of the disorder is hyperarousal, which can be defined as overreacting to innocuous stimuli, and is often described as feeling “jumpy,” or easily startled and constantly on guard.
Hyperarousal is one aspect of the autonomic nervous system, the system that controls the beating of the heart and other body functions, and governs one’s ability to respond to his or her environment. Scientists believe hyperarousal is at the core of PTSD and the driving force behind some of its symptoms.
Standard treatment interventions for PTSD offer mixed results. Some individuals are prescribed antidepressants and do well while others do not; others are treated with psychotherapy and still experience residual affects of the disorder.
Sudarshan Kriya Yoga is a practice of controlled breathing that directly affects the autonomic nervous system. While the practice has proven effective in balancing the autonomic nervous system and reducing symptoms of PTSD in tsunami survivors, it has not been well studied until now.
“A clinician could use a ‘tool box’ of psychological assessments to determine the cognitive and emotional style of the patient, and thereby determine a treatment that would be most effective for that individual,” he says. “Right now, a large fraction of individuals who are given any one type of therapy are not improving on that therapy. The only way we can improve that is if we determine which kinds of people will benefit most from different types of treatments.”
That assessment is critical. At least 22 veterans take their own lives every day, according to the U.S. Department of Veterans Affairs. Because Sudarshan Kriya Yoga has already been shown to increase optimism in college students, and reduce stress and anxiety in people suffering from depression, it may be an effective way to decrease suffering and, quite possibly, the incidence of suicide among veterans.
