Art has been used as a means of communication, self-expression, group interaction, diagnosis, and conflict resolution throughout history. For thousands of years, cultures and religions around the world have incorporated the use of carved idols and charms, as well as sacred paintings and symbols, in the healing process. The establishment of art therapy as a unique and publicly accepted therapeutic approach only took place recently, in the mid-20th century. The emergence of art therapy as a profession arose independently and simultaneously in the United States and Europe. The term "art therapy" was coined in 1942 by British artist Adrian Hill, who discovered the healthful benefits of painting and drawing while recovering from tuberculosis. In the 1940, several writers in the mental health field began to describe their work with people in treatment as "art therapy". As there were no formal art therapy courses or training programs available at that time. These care providers were often educated in other disciplines and supervised by psychiatrists, psychologists, or other mental health care professionals. Art therapy came into existence in the middle of the 20th century. It is based on the concept of visual representations, in order to express one's feelings. Paints, chalks, and clay are the essential tools of art therapy. The therapy actually aims to relax an exerted brain and psychology, in order to refresh it, stabilize it, and make it more receptive. Art therapy is therefore especially useful for the people who stress a lot at the work place, and for those who have mental tensions. In addition, the therapy also helps people who are slow learners or are mentally ill. Art therapy is beneficial to sustain mental health and emotional well-being. The treatment involves drawing, sculpture, photography, and visual art as a vent to expressions.
