The progress of the times leads people to explore the needs of the spiritual world in addition to meeting the needs of daily life, and art has become a fashionable word. Art spaces are no longer just museums and art galleries. Artists have begun to pursue an independent space to express the stories they want to express to the public. After entering the space, people can often follow the artist's settings for an immersive experience, find resonance in the artist's world, and have answers to their own stories, which is also the healing nature of the art space. This paper demonstrates the theoretical basis of the healing property of art space by discussing the concept of art therapy, and discusses the healing property of art space from the two aspects of sensory experience and lighting atmosphere of art space.
