Definition

Yoga (Sanskrit: योग) is a physical, mental, and spiritual practice or discipline that denotes a variety of schools, practices and goals in Hinduism, Buddhism (including Vajrayana and Tibetan Buddhism) and Jainism, the best-known being Hatha yoga and Raja yoga.

The origins of Yoga have been speculated to date back to pre-Vedic Indian traditions, but most likely developed around the sixth and fifth centuries BCE, in ancient India's ascetic circles, which are also credited with the early sramana movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Hindu Upanishads and Buddhist Pāli Canon, probably of third century BCE or later. The Yoga Sutras of Patanjali from first half of 1st millennium CE is one of a key surviving major texts on Yoga. Hatha yoga texts emerged around 11th century CE, and in its origins was related to Tantrism.

Yoga gurus from India later introduced yoga to the west, following the success of Swami Vivekananda in the late 19th and early 20th century. In the 1980s, yoga became popular as a system of physical exercise across the Western world. Yoga in Indian traditions, however, is far more than physical exercise, it has a meditative and spiritual core.

Yoga as exercise or alternative medicine is a modern phenomenon which has been influenced by the ancient Indian practice of hatha yoga. It involves holding stretches as a kind of low-impact physical exercise, and is often used for therapeutic purposes. Yoga in this sense often occurs in a class and may involve meditation, imagery, breath work and music.

 

Research

Both the meditative and the exercise components of hatha yoga have been researched for both specific and non-specific health benefits. Hatha yoga has been studied as an intervention for many conditions, including back pain, stress, and depression.  Studies support yoga improving quality of life, but it has not been proven to effectively treat disease.

A survey released in December 2008 by the US National Center for Complementary and Alternative Medicine found that hatha yoga was the sixth most commonly used alternative therapy in the United States during 2007, with 6.1 percent of the population participating.

Much of the research on Hatha Yoga has been in the form of preliminary studies or clinical trials of mixed methodological quality; issues include small sample sizes, inadequate blinding, lack of randomization, and high risk of bias.[16][17] As of 2011, evidence suggests that Hatha Yoga may be effective at improving health outcomes as a form of mild physical exercise when added to standard care. Hatha Yoga does not have specific and standardization regarding its practice. A study suggested for creation of supported practices that could be distributed and applied for use in clinical practice for patients.[18]

 

Mental health conditions

Yoga is a core component of the Mindfulness-based stress reduction (MBSR) program. Drawing from recent research on the mental and physical benefits of practicing yoga, positive psychologists have begun to look deeper into the possibilities of utilizing yoga to improve life for people even in the absence of disease.[18]

The therapeutic benefits of yoga have been discussed by van der Kolk, who explains that because regulation of physical movement is a fundamental priority of the nervous system, focusing on and developing an awareness of physical movement can lead to improved synchrony between mind and body. This is beneficial, he says, especially for those suffering from psychological conditions such as depression and PTSD (the focus of van der Kolk’s work), because an improved sense of connectedness between mind and body give rise to enhanced control and understanding of their "inner sensations" and state of being.[18]

A 2010 literature review of the research on the use of Hatha Yoga for treating depression said that preliminary research suggests that Hatha Yoga may be effective in the management of depression. Both the exercise and the mindfulness meditation components may be helpful. However the review cautioned that "Although results from these trials are encouraging, they should be viewed as very preliminary because the trials, as a group, suffered from substantial methodological limitations."[19]

A 2015 systematic review on the effect of yoga on mood and the brain concluded that "yoga is associated with biological changes in blood pressure, heart rate, cortisol or cytokine levels. It is therefore plausible that yoga may affect mood via SNS and HPA axis regulation."[20] The same review also points to a lack of research in this field and recommends more methodological rigor be applied to future RCTs to solidify these conclusions.

There is some evidence that exercise programs such as yoga may help people with dementia perform their daily activities.[21] No benefit to treating attention deficit hyperactivity disorder has been confirmed, despite some tests.[16] There is some evidence supporting yoga as an alternative treatment for insomnia, however it is not clear whether yoga works better than general relaxation techniques.[22]

 

Physical health conditions

There is evidence that Hatha Yoga may be effective in the management of chronic, but not necessarily acute, low back pain.[23] There is some evidence to support the use of Hatha Yoga as a complementary therapy for helping people with rheumatic diseases, but the evidence is not concrete and the safety of such a course is uncertain.[24]

Although some evidence exists to suggest Hatha Yoga might help people with high blood pressure, overall this evidence is too weak for treatment to be reliably or safely recommended.[25] There is no evidence of benefit in treatment of epilepsy or menopause-related symptoms.[26][27] Practice of Hatha Yoga may improve quality-of-life measures in cancer patients,[28] though it should be noted yoga has no effect on the underlying disease.[4]
