Stress and Amounts of Urban Green (01-16-19)

Rawal studied how much greenery is necessary to support recovery from stressful situations.  He reports that “Psychological stress was first induced in the participants using Trier Social Stress Test (TSST) and then they were randomly assigned to experience one of four, 360-degrees panoramic images of an urban park using Immersive Virtual Environment (IVE). Three groups viewed images of urban parks with density of vegetation varying from 3% to 70%, while the control group viewed an image with no nature elements. .  . .

Advantages of Green Exercise (01-03-19)

There are clear advantages to exercising in green environments.  Wooller and colleagues determined that when “Fifty participants were randomly assigned to one of five groups: REST [sitting quietly on a cycle ergometer in front of a gray screen], exercise, exercise with nature sounds, exercise withnature visual and exercise with nature sound and visual. . . . Results showed that green exercise improved mood and stress scores more than exercise alone or REST.

Overlays, Views, and Stress (12-26-18)

Research conducted with children may indicate a way to at least partially compensate for lack of nature views in areas where people are likely to feel stressed.  Pearson and team collected data from pediatric hospital patients (2-18 years old) who were assigned to hospital rooms that either had no applique like overlays that partially covered the windows of their rooms or realistic overlays on their windows that were reminiscent of an undersea environment (“aquatic animals and sea plants”) or a wooded meadow (“greenery, trees, and grass”).

Feeling Crowding (11-26-18)

Wang and Ackerman studied factors that influence how crowded people feel in a space.  They determined that  “People sometimes perceive social environments as unpleasantly crowded. Previous work has linked these experiences to incidental factors such as being hungry or hot and to the relevance of the social environment for an individual’s current goals. Here. . . . Eight studies test whether infectious disease threats, which are associated with crowded conditions, increase such reactions.

More on What’s Mentally Refreshing (11-21-18)

Kuper investigated the cognitive refreshment/restoration related implications of viewing different sorts of nature scenes.  He found that “Respondents rated flowering and autumn-colored views significantly higher in RP [restorative potential] and preference than foliated [green leaves only on trees]. . . . Flowering plants and red or yellow autumn-colored foliage may increase users’ preference and RP.”
