Research problem and context Traditionally, healthcare facilities were built with the emphasis on the functional delivery of health care. However, since research has shown that the built healthcare environment can impact the health and well-being of patients, more attention is being paid to the psychological consequences of architectural choices. Such psychologically supportive environments are also referred to as healing environments. Understanding physical environmental stimuli in healthcare facilities will allow us to create environments that positively affect the health and well-being of patients. In addition, understanding the underlying processes causing these effects may help us to design healing environments more efficiently
