Yoga has been found to be effective in promoting health and is useful in improving the conditions of patients with cardiovascular diseases, stroke, diabetes and mental disorders. It is recognized as an tool to promote physical activity and recognized as such by WHO. With support from the Ministry of Ayurveda, Yoga & Naturopathy, Unani, Siddha and Homoeopathy (Ministry of AYUSH), Govt of India, WHO is developing a Benchmark Document for Training in Yoga as part of its global strategy to strengthen the quality, safety and effectiveness of Traditional and Complementary Medicine. This partnership has gone from strength to strength, most recently with the development of the mYoga app. This is an app for the general public and for yoga teachers to use in their daily life and teaching. It includes WHO approved yoga teaching and practice sessions of different durations developed through extensive international expert consultation processes. The app is safe and secure, collecting no data from users at all, and can be used as a daily yoga companion for persons aged 12-65 years. It will be available in all six UN languages and in Hindi.
