04 Aug 2010Diana E Bowler, Lisette M Buyung-Ali, Teri M Knight and Andrew S Pullin

Findings provided some evidence of a positive benefit of a walk or run in a natural environment in comparison to a synthetic environment. There was also some support for greater attention after exposure to a natural environment but not after adjusting effect sizes for pretest differences.
