This study aimed to compare th effect of viewing forest and urban landscapes on the physiological responses and the psychological status of radiologists. An experiment was conducted among 10 healthy raiologists (n=10, 24±2.9 years old). They were instructed to view forest and urban landscapes, and their HRV (Heart Rate Variability) was measured to assess their physiological responses, and POMS (Profile of Mood States), and SD (Semantic Differential) questionnaires were also conducted to assess their psychological status. The collected data were analyzed with Wilcoxon signed-rank test using the SPSS 21.0. The results showed that viewing the forest landscape stimulated the activity of the parasympathetic nervous system more than viewing the urban landscape, which reduced stress and stabilized the psychological status of participants, and that viewing the forest landscape also increased the levels of positive feelings among POMS and SD subscales. Therefore, it was concluded in this study that viewing forest landscapes can contribute to the reduction of stress, emotional stability, and positive psychological status of those who work in a closed space like radiologists.
