Art therapy is a form of psychotherapy that uses the creative process of making art to improve a person's physical, mental, and emotional well-being. The idea behind art therapy is that the act of creating art can serve as a therapeutic tool for exploring and expressing feelings, thoughts, and experiences. The process of art-making can also help to reduce stress, increase self-esteem, and provide a sense of accomplishment. Art therapy is often used as a complementary treatment for various mental health conditions, such as depression, anxiety, and post-traumatic stress disorder (PTSD).
