PATIENT CARE AND HEALING
“Mounting research is providing convincing evidence that
visual exposure to nature improves outcomes such
as stress and pain.”
“Ulrich (1984) found that patients recovering from
abdominal surgery recovered faster, had better
emotional well-being, and required fewer strong pain
medications if they had bedside windows with a nature
view (looking out onto trees) than if their windows looked
out onto a brick wall.”

the 21st Century: A Once-in-a-Lifetime Opportunity
(Ulrich, Zimring, 2004) Chicago City Hall | Roofscapes Inc.
“Today, we know that being
surrounded by nature plays a
significant role in patient outcome.”

STAFF AND FAMILY BENEFITS
“Hospital gardens not only provide restorative or calming nature
views, but can also reduce stress and improve outcomes through
other mechanisms, for instance, fostering access to social
support and providing opportunities for positive escape and
sense of control with respect to stressful clinical settings.”
- (Cooper Marcus & Barnes, 1995; Ulrich, 1999).
“. . . Many nurses and other healthcare workers used the
gardens for achieving pleasant escape and recuperation from
stress.”
“Patients and family who use hospital gardens report positive
mood change and reduced stress. These reports also suggest
that gardens and nature in hospitals can heighten patient and
family satisfaction with overall quality of care.”
