Yoga is an umbrella term for all the present physical, mental, and spiritual practices that originated in ancient India. Then, it was practised with a view to attain a state of permanent peace; yoga has been defined as "the stilling of the changing states of the mind."
Yoga has been widely used as a complementary intervention for cancer patients, to increase anxiety control and to decrease depression, insomnia, pain, and fatigue.
Many studies have tried to determine its effectiveness as a complementary intervention for cancer, schizophrenia, asthma, and heart disease. The results of these studies have been mixed and inconclusive, with cancer studies suggesting none to unclear effectiveness, and others suggesting yoga may reduce risk factors and aid in a patient's psychological healing process.
On December 1, 2016, yoga was listed by UNESCO as an Intangible cultural heritage.
