Forest & Health
The thematic research program Forest and Health examines whether and how human health is affected by visits to forest environments and how this knowledge can be extended to forest management operations.
The research area is new and has not previously existed in the Faculty of Forest Sciences at SLU. The program is led by the researchers Ann Dolling and Ylva Lundell. One doctoral thesis has been produced within the program by PhD Elisabet Sonntag-Öström. The graduate student Patrik Umaerus coordinates one of the projects.
Forest and Health is an interdisciplinary program which is working closely together with medical doctors, psychologists, physiotherapists and others at the Stress Clinic, University Hospital of Umeå, researchers at the Department of Public Health and Clinical Medicine and Department of Psychology at Umeå University as well as researchers at SLU in Umeå and Alnarp.
Forest and Health has been funded by the Faculty of Forest Sciences (SLU), Sveaskog forest company, Umeå municipality, the Swedish Forest Agency, the Swedish Forest Society, Petersson-Grebbe foundation, Västerbotten County Council and the Centre for Environmental Research (CMF), Umeå. The graduate student is funded by the Swedish Research Council Formas.
Forest and Health includes the following projects:
1) EnRest (Environments for Rest)
"A comparative study of two stress-recovery environments"
The project has studied if a stay in the forest, or in a handicraft environment, can reduce stress levels and if any of the environments is better than the other in curing stress. The intention was also to find out what aspects in the environment that were affecting a possible mental recovery. In this project, persons with high stress levels visited one of the environments two times a week for 3 months.
A paper about this study is under review in a scientific journal, and part of the study is evaluated in a master thesis (Jönsson, 2013).
2) ForRest (Forests for Rest)
"Nature's role in stress and exhaustion disorder"
The randomised controlled study ForRest investigated whether staying in forest environments can provide restoration effects and accelerate recovery in patients with exhaustion disorder. We also studied more closely the forest environments that were perceived as restorative, what components in them that were of importance and what silviculture actions that were needed in forest management in order to be able to use them as rehabilitation forests.
Persons diagnosed with exhaustion disorder participated in the project. Half of them were randomly assigned to spend two hours a week for 3 months in one of eight different forest environments. The other participants were randomly assigned to the control group. All participants (forest and control groups) got, after the three initial months, cognitive behavioral group rehabilitation at 24 occasions, once a week.
Evaluation of the initial pilot study is presented in Sonntag-Öström et al. 2011. Evaluation of the main part of the study is included in the PhD thesis of Elisabet Sonntag-Öström, presented at Umeå University in September 2014. Two papers with quantitative (Sonntag-Öström et al., 2015 [Can rehabilitation……]) and qualitative (Sonntag-Öström et al., 2015 [”Natures effect ……]) results, respectively, are published.
3) Green rehabilitation in family forest farms from a rural perspective.
Swedish forestry has traditionally been based on timber production. In this project we investigate biological and institutional barriers and opportunities in alternative types of economic activities in small family forest farms, and their importance for the local economy. Work on a paper about this study is under progress.
"The immediate effects of outdoor environment on stress and burnout"
In this project, we compared how a short stay (less than an hour) in different forest environments affected the health of people with exhaustion disorder. The environments used in the study were three different forest environments (from the ForRest study) and one urban environment.
Results from the study are included in the PhD thesis of Elisabet Sonntag-Öström. They are also presented in the paper Sonntag-Öström et al. 2014.
5) A GPS-study of choice of environment for people with stress-related fatigue
The study investigated, by use of GPS recorders, in detail where in different forest environments that people diagnosed with chronic fatigue syndrome preferred to reside. The study was a substudy of ForRest, where the participants had to select one of eight forest environments for their two hour forest visits. The field part of the project has ended and the study is now being evaluated.
6) The optimal character and management of rehabilitation forests in combination with timber production
The aim of the project was to a) on the basis of the large data sets collected for the project ForRest as well as results from Alnarp rehabilitation garden, "transfer" the mental and rehabilitative experience of persons with exhaustion disorder to forest characters and forest data, 2) identify rehabilitation forests and their distribution in the landscape, and 3) by using the Heureka-system as planning tool do scenario analysis of how the proportion of rehabilitation forests in combination with forestry for timber production could be optimized with minimal economic loss. The project has been conducted in collaboration with researchers at SLU in Umeå and Alnarp.
