Hospital patients with views of nature recover faster and need less pain medication.

In 1984, environmental psychologist Roger Ulrich published a groundbreaking study in the journal Science titled 'View Through a Window May Influence Recovery from Surgery.' He analyzed records from a suburban Pennsylvania hospital between 1972 and 1981, focusing on patients recovering from gallbladder surgery. The study compared 23 patients in rooms with windows overlooking trees to 23 patients whose windows faced a brown brick wall.The results were statistically significant. Patients with the nature view spent an average of 7.96 days in the hospital, while those facing the wall stayed for 8.70 days. Furthermore, the nature-view group received far fewer doses of strong narcotic analgesics. Nurses also reported that patients with nature views had better moods and fewer negative evaluation comments in their charts.This phenomenon is explained by 'Biophilia,' a term popularized by Edward O. Wilson, which suggests humans have an innate connection to the natural world. Viewing nature triggers the parasympathetic nervous system, which lowers cortisol levels and heart rate. When the body is in a relaxed state rather than a stressed one, the immune system can allocate more energy to tissue repair and inflammatory regulation. Modern hospitals now use these findings to implement 'Evidence-Based Design,' prioritizing green spaces to improve clinical outcomes.
