Yale University

A randomized controlled study run by Yale University scientists evaluated the effect of SKY and two other programs, Mindfulness-Based Stress Reduction and Emotional Intelligence, on undergraduate well-being as compared to a control group. Mindfulness-Based Stress Reduction showed no improvement compared to the control group, Emotional Intelligence showed  improvement in mindfulness, and SKY had the highest results of all the programs, benefiting stress, depression, mental health, mindfulness, positive emotion and social connectedness.

University of Arizona 

A randomized controlled study run by University of Arizona researchers, evaluated the effect of SKY versus a cognitive focused intervention. SKY demonstrated improvements in perceived stress, sleep, social connectedness, distress, anxiety, depression, conscientiousness, self-esteem, and life satisfaction, while the control group did not. SKY also led to improved sleep and stress reactivity. Results were observed immediately after and 3 months after the workshop.

In other studies, SKY practitioners show:

Stress and anxiety 

In a randomised controlled trial of 135 university students,  Sudarshan Kriya™ reduced stress and anxiety more than mindfulness or emotional intelligence programmes.

Insomnia

The 2024 physician RCT found a statistically significant 3-point reduction in insomnia scores in the Sudarshan Kriya™ group vs the control group, using a validated clinical insomnia scale.

Burnout and exhaustion

Physicians assigned to Sudarshan Kriya™ showed significantly less work exhaustion and burnout than those who received stress management education alone, suggesting it's a practical, safe way to improve wellbeing across high-stress professions.

Depression

A randomised pilot study at the University of Pennsylvania found Sudarshan Kriya™ significantly lowered depression scores in antidepressant-resistant patients with major depressive disorder.

Emotional regulation 

A study in patients with anxiety and depression found that Sudarshan Kriya™ improved heart rate variability, a physiological marker of how well the nervous system regulates stress and emotion.

Wellbeing and optimism 

In a controlled study of 103 Swedish adults, Sudarshan Kriya™ significantly reduced anxiety, depression, and stress, and increased optimism (p<0.001) over six weeks, versus no change in controls.
