The study explored subjective mental health change in adults aged 60 to 100 by experiencing immersive virtual reality (IVR)-based on the natural environment. It investigated changes in thinking, behaviour, and emotions from a socioecological perspective. The study conducted quantitative surveys of 540 older adults via IVR who lived in 20 longevity villages in South Korea from Dec. 2022 to Nov. 2023. It also paralleled a qualitative study with 38 of the 540. Study results predicting subjective mental health changes after experiencing IVR in those over 70 showed the highest gladness and happiness. In over 70 compared with 60 to 69 ages, the study found that relieving stress and depression, gladness and happiness, and relaxing the mind have about two-fold subjective mental health changes after experiencing IVR. The study suggests that it can be utilized to promote subjective mental health through the experience of an IVR-based natural environment for older adults.
