Yoga is an umbrella term for all the present physical, mental and spiritual practices that have come down to us from ancient India. Then, it was practised with a view to attain a state of permanent peace, and 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 decrease depression, insomnia, pain, and fatigue and increase anxiety control.
Many studies have tried to determine it's 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 as UNESCO's Intangible cultural heritage.
