Silva Cells Bring Trees to Life at Hospitals Around the World

Trees provide enormous benefits on both macro and micro scales for human health and as a key component in combating climate change. Beyond their obvious beauty, they heal people and places and provide substantial ecosystem benefits, including reducing urban heat island effect, managing, and cleaning stormwater, capturing carbon, filtering air pollution, and providing habitat for birds.

Substantial research has been undertaken to measure the impact of trees on recovery for patients in hospitals, and the results are clear. Trees and greenery can heal and speed a sick person’s recovery simply by being in sight.

Since the 1980s, environmental psychologists have studied the effects trees have on patients at hospitals seeing trees and greeneries versus a brick wall. They found patients who have view of trees heal faster, use fewer pain medications, and leave the hospital sooner than patients who didn’t have a view of greenery, and patients with a view of trees spent 8 percent fewer days in the hospital.

DeepRoot is proud to be able to provide a cost-effective solution to the challenge of growing mature trees in confined spaces and we’ve provided the Silva Cell solution and increased tree canopy growth at over 20 hospitals, rehabilitation, trauma, and healing centers around the world. Here is a selection of just a few of the great projects we’ve worked on to bring trees to patients in health care settings.
