Yoga Therapy and Research

Research allows Yoga Therapists to provide accurate and ethical protocols that are underpinned by a firm evidence base. This allows us to support our clients safely and effectively.

Here are some links to research and articles on a variety of health and well-being conditions and yoga.

General Research


Chronic Pain

This IAYT white paper explains that yoga therapy can make a meaningful contribution to solving the overlapping public health crises of chronic pain, opioid misuse and overdose, and mental health disorders. The authors describe yoga therapy as a key component in comprehensive integrative pain management, noting that this centred intervention positively addresses body and mind and focuses on overall well-being, quality of life, and flourishing within one’s life circumstances.

Recent findings have demonstrated that mindfulness meditation significantly reduces pain. The practice of meditation activates specific brain areas known to be involved in pain modulation. In this study, mindfulness meditation provided a stronger analgesic effect than a placebo or sham meditation.
Zeidan F, et al. Mindfulness meditation-based pain relief employs different neural mechanisms than placebo and sham mindfulness meditation-induced analgesia. The Journal of Neuroscience 2015;35:15307–25.


After 4 days of mindfulness meditation training, meditating in the presence of noxious stimulation significantly reduced pain unpleasantness by 57% and pain intensity ratings by 40% when compared to rest. This study also explored the impact of the practice of mindfulness meditation on brain areas associated with pain modulation.
