Cheng and colleagues replace static green-versus-grey comparisons with sequential exposure, treating restoration as a process that unfolds while bodies move through changing environments. Twenty participants walked grey–green–grey routes while restoration was tracked through pre/post psychometrics, heart-rate variability and minute-level micro-surveys. The study’s key empirical proposition is temporal carry-over: green exposure produced a short-term “inoculation effect” whose restorative benefit persisted after participants re-entered grey settings. Visual features were the strongest predictors, followed by noise and microclimate. Methodologically, the work is important because it decomposes a walk into temporally ordered environmental transitions rather than treating a route as one exposure unit. It bridges environmental psychology, spatial sensing, physiological measurement and computational interpretation. More broadly, it demonstrates that environment–experience relations possess memory: what a person encounters now partly conditions how the next setting is experienced, making sequence itself an analytical variable.
