Despite advances in traditional therapy and drug-based treatments, a recent study shows that only 50% of patients who complete such treatments recover (Ballenger et al., 2000)! There is a critical need for alternate approaches to the anxiety, trauma, rage, sleeplessness, and other side-effects of war. More and more VA hospitals and community veteran centers are turning to mind-body practices such as breathing, yoga and meditation. Preliminary research results are promising and many veterans claim that these practices have been extremely helpful.

About SKY (Sudharshan Kriya Yoga)

The Power Breath Meditation Workshop is a mind-body resilience building program for returning veterans. A cornerstone of the Power Breath Meditation Workshop is the SKY (Sudarshan Kriya Yoga) Practice, a set of breathing techniques. SKY has been shown to reduce anxiety, depression and stress, and to increase self-reported optimism and well-being (Brown and Gerbarg, 2005; Kjellgren, Bood, Axelsson, Norlander, & Saatcioglu, 2007; Janakiramaiah, 2000). One study suggested that SKY may be effective for PTSD in particular. Patients with PTSD stemming from the 2004 Tsunami benefited equally from SKY alone as from a combination of SKY and exposure therapy when compared with a wait-list control (Descilo et al., 2009). SKY has even been shown to positively impact rapid gene expression alterations (Qu et al., 2013).

Current research at the University of Wisconsin-Madison suggests that the workshop provided by Project Welcome Home Troops may reduce post-traumatic stress. The research will be published later this year. The University of Wisconsin has now receive further funding for a much larger study using the Project Welcome Home Troops workshop and using brain-imaging methods. For more information about the ongoing study and to hear more from the researchers and the veterans who have participated, you can watch several televised news reports including NBC, Channel 3, and news articles describe promising initial findings and veteran testimonials.

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.

Research by Stanford scholar Emma Seppala at the Center for Compassion and Altruism Research and Education found that post-traumatic stress disorder decreased in veterans who participated in a weeklong breathing, yoga and meditation workshop, and remained lower a year later.

Summary of Research Findings on Breathing Techniques

Controlled respiration exercises are aimed at reducing anxiety and arousal by bringing the body to a physiologically relaxed state (Feuerstein & Miller, 1998). Emotion regulation research shows that respiration and emotion are tightly linked psychological processes (Boiten et al. 1994) and that emotions produce particular rhythms of breath which, when replicated, can induce that emotion (Phillippot, 2002). Research suggests that controlled respiration exercises bring immediate, experienced effects among psychiatric patients (Brown & Gerbarg, 2009). Controlled breathing interventions have resulted in decreased depression (Murthy et al., 1998; Pilkington et al., 2005) and anxiety (Clark and Hirschman 1990). Controlled respiration exercises also appear to reduce pain thresholds (Zautra et al., 2010) and to alleviate withdrawal symptoms in smokers (McClernon et al., 2004). Studies suggest that the effects of controlled respiration techniques on stress and anxiety may be due to respiration’s effects on physiological indicators of autonomic balance including increased tone in the vagus nerve (Raghuraj et al., 1998; Raghuraj & Telles, 2008). Controlled breathing exercises have also been shown to reduce pain thresholds (Zautra et al., 2010) and withdrawal symptoms in nicotine dependence (McClernon et al., 2004).

Summary of Research Findings on Sudharshan Kriya

Sudarshan Kriya is a controlled respiration technique taught in the workshops offered by the Art of Living Foundation and the International Association for Human Values. Its effects have been studied in open and randomized trials, both in healthy populations and in populations with psychopathology. Research suggests that Sudarshan Kriya may reduce depression, anxiety, and stress, and that it increases well-being, optimism, and mental focus (Bhatia et al., 2003; Janakiramaiah et al., 2000; Kjellgrenet al., 2007; Kochupillai et al., 2005; Murthy et al., 1998; Vedamurthachar et al., 2006) and that it can help improve emotion regulation (Gootjes et al., 2011). These effects may be mediated by benefits to the immune system (Kochupillai et al., 2005) and improvements in the antioxidant defense mechanisms (Sharma et al., 2003; Sharma et al., 2008).

With regards to post traumatic stress, a recent study suggests that Sudarshan Kriya helps reduce the symptoms of post-traumatic stress disorder (Descilo et al., 2009) and helps curb addictive behavior such as substance abuse (Brown & Gerbarg, 2005; Kochupillai et al., 2005).

Breathing exercises may be counter-indicated for certain health conditions. In these cases, our instructors are trained in teaching alternate and adapted versions of the exercises. It is always advised to check with your health provider when engaging in any new change to your health regiment.
