Hospitals have started studying the influence of arts on patient care and found that participants in art programs have better vitals and fewer complications sleeping. Artistic influence does not need to be participation in a program, but studies have found that a landscape picture in a hospital room had reduced need for narcotic pain killers and less time in recovery at the hospital. In addition, either looking at or creating art in hospitals helped stabilize vital signs, speed up the healing process, and in general, bring a sense of hope and soul to the patient. Family, care workers, doctors and nurses are also positively affected.
