Findings from several studies of non-patient groups suggest that even brief visual encounters with real or simulated natural settings can elicit significant psycho-physiologic restoration within as little as 3 - 5 min [6,16-18]. This restoration is manifested as reduced negative effects, and heightened positive effects and changes in physiologic systems that are indicative of reduced arousal or stress mobilization (electrocortical, cardiovascular, neuroendocrine and musculoskeletal) [17].
