According to the International Journal of Yoga, Sudarshan Kriya is a type of yoga focused on breathing exercises aimed at improving mental well being and organ function. For some, it can alleviate depression, anxiety and stress by providing a feeling of calm, and it may have long term effects.
Sudarshan Kriya yoga is an ancient and traditional healing technique. Conventional medicine has begun testing the benefits of these breathing exercises. Evidence has shown that it can be effective in treating some mental conditions. Risks and costs associated with practicing most breathing exercises are extremely low, but it's not a comprehensive treatment for serious mental health issues.
