Wood Odor Mapping on Arousal Axes
This study mapped a wide range of naturally derived odors, including those derived from wood, on the two-dimensional axes of tense arousal (TA) and energetic arousal (EA), and examined whether quadrant differences influenced recovery following stress. In the context of Attention Restoration Theory and biophilic design, the study provided preliminary evidence that olfactory stimuli can be treated as a designable element in a functional and reprodu…
Subjective Interactions of Wood-Derived Olfactory and Visual Stimuli During Work and Rest
This study investigated the effects of wood-derived visual and olfactory stimuli on subjective evaluations during work and rest. Twelve participants experienced seven conditions involving walnut panel interiors, Hinoki cypress scents, or their combination, introduced during either work or rest phases. A within-subjects design was used to assess spatial impressions, mood states, and fatigue. Visual stimuli significantly improved visual impressions…
Heart rate and heart rate variability in infants during olfactory stimulation
Background: Various plant odours have been shown to decrease heart rate and increase parasympathetic nervous activity. However, 'innate' autonomic responses without the influences of experience, assumptions and prejudices of odours remains unclear. Aim: To clarify changes in heart rate and heart rate variability in infants while presenting different components of plant odours. Subjects and methods: The study participants included 17 infants aged …
Essential Oil of Japanese Cedar (Cryptomeria japonica) Wood Increases Salivary Dehydroepiandrosterone Sulfate Levels after Monotonous Work
Employee problems arising from mental illnesses have steadily increased and become a serious social problem in recent years. Wood is a widely available plant material, and knowledge of the psychophysiological effects of inhalation of woody volatile compounds has grown considerably. In this study, we established an experimental method to evaluate the effects of Japanese cedar wood essential oil on subjects performing monotonous work. Two experimen…
Influence of Forest Therapy on Cardiovascular Relaxation in Young Adults
Background . Despite increasing attention toward forest therapy as an alternative medicine, very little evidence continues to be available on its therapeutic effects. Therefore, this study was focused on elucidating the health benefits of forest walking on cardiovascular reactivity. Methods . Within‐group comparisons were used to examine the cardiovascular responses to walking in forest and urban environments. Forty‐eight young adult males partic…
The influence of urban green environments on stress relief measures
Emotional, Restorative and Vitalizing Effects of Forest and Urban Environments at Four Sites in Japan
The present study investigated the well-being effects of short-term forest walking and viewing ("forest bathing"). The hypothesis in our study was that both environment (forest vs. urban) and activity (walking and viewing) would influence psychological outcomes. An additional aim was to enhance basic research using several psychological methods. We conducted the experiments using 45 respondents in four areas of Japan from August to September, 201…
Physiological and psychological effects of viewing urban forest landscapes assessed by multiple measurements
Carbon balance assessments of harvested wood products in Japan taking account of inter-regional flows
Effect of forest bathing on physiological and psychological responses in young Japanese male subjects
Trends in research related to “Shinrin-yoku” (taking in the forest atmosphere or forest bathing) in Japan
"Shinrin-yoku", which can be defined as "taking in the forest atmosphere or forest bathing", has been receiving increasing attention in Japan in recent years for its capacity to provide relaxation and reduce stress. Since 2004, the authors of this paper have been involved in an investigation designed to ascertain the physiological effects of "Shinrin-yoku" within the framework of the "Therapeutic Effects of Forests" project. We have conducted phy…
The physiological effects of Shinrin-yoku (taking in the forest atmosphere or forest bathing)
This paper reviews previous research on the physiological effects of Shinrin-yoku (taking in the forest atmosphere or forest bathing), and presents new results from field experiments conducted in 24 forests across Japan. The term Shinrin-yoku was coined by the Japanese Ministry of Agriculture, Forestry, and Fisheries in 1982, and can be defined as making contact with and taking in the atmosphere of the forest. In order to clarify the physiologica…
Restorative effects of viewing real forest landscapes, based on a comparison with urban landscapes
Growing attention has been paid to the health-enhancing or therapeutic effects of natural environments, such as forests, and the requirement for an evidence-based approach has been pressing. However, there is a lack of evidence-based research in this field. In this study, the restorative effects of viewing real forest landscapes were examined through field experiments by comparing the effects of urban landscapes. Twelve Japanese male subjects in …
Physiological Effects of Shinrin-yoku (Taking in the Atmosphere of the Forest) in an Old-Growth Broadleaf Forest in Yamagata Prefecture, Japan
The physiological effects of "Shinrin-yoku" (taking in the atmosphere of the forest) were examined by investigating blood pressure, pulse rate, heart rate variability (HRV), salivary cortisol concentration, and immunoglobulin A concentration in saliva. Subjective feelings of being "comfortable", "calm", and "refreshed" were also assessed by questionnaire. The subjects were 12 male university students aged from 21 to 23 (mean+/-SD: 22.0+/-1.0). Th…
Physiological Effects of Shinrin-yoku (Taking in the Atmosphere of the Forest)—Using Salivary Cortisol and Cerebral Activity as Indicators
The purpose of this study is to examine the physiological effects of Shinrin-yoku (taking in the atmosphere of the forest). The subjects were 12 male students (22.8+/-1.4 yr). On the first day of the experiments, one group of 6 subjects was sent to a forest area, and the other group of 6 subjects was sent to a city area. On the second day, each group was sent to the opposite area for a cross check. In the forenoon, the subjects were asked to walk…
