Objectives To evaluate the effect of a forest experience on the levels of depression of alcoholics. Methods Prior to the study, 92 alcoholics were divided into treatment and control groups. During the summer of 2009, the treatment group participated in a series of forest therapy programs, while the control group followed their normal daily routines. Both groups were re-tested upon completion of the program by the treatment group and the depression levels compared. Results There was a significant improvement in the depression level of alcoholics who had participated in the forest camp program (treatment group). Those participants in their 40s who had severe levels of depression at the beginning of the program showed the most significant improvement during the program experience. Conclusion The forest therapy camp experience can considerably reduce and ameliorate the depression levels of alcoholics.
The aims of this study were twofold: to examine the empirical evidence supporting the positive contribution that a forest environment can make on human psychological health and well-being and to describe the theoretical framework within which the forest environment has this effect. Our review of the literature provides empirical evidence that a forest experience can contribute to improved emotional and cognitive health.This experience can be through a forest activity program and by experiencing the social and physical conditions of the forest environment and the therapeutic elements of the forest. Visiting or viewing a forest scene has been documented to have a positive effect on psychological healing and well-being in terms of recovering from stress, improving concentration and productivity, improving the psychological state, particularly for people from urban environments. Wilderness and related studies clearly demonstrate that being in a forest environment has a positive effect on people, while results from other studies indicate that contacts with forest environments provide multiple positive physiological and psychological effects on human health that included decreasing the blood pressure and heart rate and reducing anxiety and stress. There are several theories explaining the healing effects of the forest on human beings. Most hypothesize that restorative environments are settings in which recovery is associated with the reduction of stress and that the benefits of contact with natures include a wide range of positive physiological and psychological responses. These theories are based on an evolutionary perspective and share a number of similarities and differences. This article summarizes a number of these theories of restorative environments as well as addresses the current status of forest therapy and the challenges and opportunities for therapeutic effects of the forest in Korea.
Windows have been found to be a particularly salient feature of the workplace, not only as a matter of preference but also for health and well-being. Depending on what is in the view, looking out of the window may provide numerous opportunities for restoration. This study investigated the effect of window views on job satisfaction and stress. The impact of two specific influencing mechanisms was examined: existence of forest views through windows in workplaces, and absence of forest views through windows in workplaces. The sample consisted of 931 office workers in Seoul, South Korea, 481 who could see forest views from their workplaces and 450 who could not see forest views. A set of self-administered questionnaires including job satisfaction and job stress measures was distributed to the sample from April to September 2004. The results showed a significant direct effect of forest views from windows on job satisfaction and stress. Respondents' personal information such as gender, age and job category did not influence on the window view effects. As expected, employees' job satisfaction and job stress were highly and negatively correlated.
Several studies have confirmed that the natural environment has psychophysiological healing effects. However, few studies have investigated the healing process involved in the effect of the natural environment. To date, no theoretical model on the nature-based therapy process has been clearly established. Thus, the aim of this study was to develop a theoretical model of the nature-based therapy process by analyzing individual empirical data. Research materials were 180 self-reported essays on “Forest Therapy Experiences” submitted to the Korea Forest Service. This study was conducted based on grounded theory. Data were analyzed through open coding. A total of 82 concepts, 21 subcategories, and six categories were derived. Results revealed that the nature-based therapy process contained six categories: Stimulation, acceptance, purification, insight, recharging, and change. When in the natural environment, participants first experienced positive emotional change, followed by cognitive and behavioral changes. Based on these results, a nature-based therapy process model was derived. This study revealed that the nature-based therapy process did not consist of just a single element or step, but involved an integrated way of healing with emotional and cognitive changes. This study is significant in that it derives a theoretical model of the nature-based therapy process with comprehensive mechanisms. Further research is needed to establish more systematic theoretical model.
