Stress recovery in forest or handicraft environments - an intervention study

In modern society stress is a major problem, causing lack of mental and social well-being as well as potential vulnerability to problems at work. Previous studies have found natural environments to be relaxing. In this intervention study, performed in Northern Sweden, the hypothesis was that an outdoor forest environment would be more relaxing than an indoor handicraft environment. Forty-six participants with high stress levels (PSQ >= 0.4) (33 women, 13 men, average age 48 years) were randomly assigned to visit either the forest environment (n = 27) or the handicraft environment (n = 19). The participants visited their assigned environment twice a week during three months, either in autumn or spring. During each visit they spent two hours performing, simple and undemanding activities. Psychological health outcomes were measured by the questionnaires CIS, PSQ, SCQ, SMBQ, SF-36 before and after the three months interventions. Sleeping patterns were monitored by an Actiwatch and sleep diary. The participants' mood before and after each visit were estimated by a questionnaire. The results show that the participants' health had improved after the interventions in both the forest and handicraft environments. The sleep latency increased slightly among participants in the handicraft environment. For participants in both environments the levels of fatigue, stress and burnout were all lower. They felt less limitation due to physical problems and did not feel so tired. Also their mental health had improved. From start to end of a visit to either environments the participants' mood was improved, and they felt more relaxed, alert, happy, harmonious, peaceful and clearheaded. Over time during the intervention, they also felt significantly more clearheaded. We conclude that the health of all participants improved, irrespective of the environment visited

Early Colonization with a Group of Lactobacilli Decreases the Risk for Allergy at Five Years of Age Despite Allergic Heredity

Background: Microbial deprivation early in life can potentially influence immune mediated disease development such as allergy. The aims of this study were to investigate the influence of parental allergy on the infant gut colonization and associations between infant gut microbiota and allergic disease at five years of age. Methods and Findings: Fecal samples were collected from 58 infants, with allergic or non-allergic parents respectively, at one and two weeks as well as at one, two and twelve months of life. DNA was extracted from the fecal samples and Real time PCR, using species-specific primers, was used for detection of Bifidobacterium (B.) adolescentis, B. breve, B. bifidum, Clostridium (C.) difficile, a group of Lactobacilli (Lactobacillus (L.) casei, L. paracasei and L. rhamnosus) as well as Staphylococcus (S.) aureus. Infants with non-allergic parents were more frequently colonized by Lactobacilli compared to infants with allergic parents (p = 0.014). However, non-allergic five-year olds acquired Lactobacilli more frequently during their first weeks of life, than their allergic counterparts, irrespectively of parental allergy (p = 0.009, p = 0.028). Further the non-allergic children were colonized with Lactobacilli on more occasions during the first two months of life (p = 0.038). Also, significantly more non-allergic children were colonized with B. bifidum at one week of age than the children allergic at five years (p = 0.048). Conclusion: In this study we show that heredity for allergy has an impact on the gut microbiota in infants but also that earl

“Nature's effect on my mind” : patients’ qualitative experiences of a forest-based rehabilitation programme

Aim: The aim of this study was to investigate the personal experiences and perceived effects on mind from visits to forest environments in a subset of patients with severe exhaustion disorder (ED), who participated in a randomized controlled trial for evaluation of forest-based rehabilitation. Participants: A subsample of 19 patients with diagnosed ED, who completed the three-month forest-based rehabilitation programme in the ForRest project, was interviewed. Method: The forest-based rehabilitation consisted of repeated forest visits with the main objective of spending time in rest and solitude in a chosen forest setting. Semi-structured interviews were carried out and analysed using Grounded Theory. Result: A core category and five subcategories were set up to describe the patients’ experiences and development during the forest-based rehabilitation. As patients mostly reported that they strove to achieve peace of mind during the forest visits, Striving for serenity was chosen to be the core category. At first the patients were frustrated when left alone with their own thoughts in an unfamiliar forest environment. They gradually became familiar with the forest environments and also found their favourite places where they experienced peace of mind. They were then able to rest and begin reflective thinking about their life situation, which led to ambitions to change it.The preferred forest environments were characterised by openness, light and a good view, and were felt to be undemanding, peaceful and stimulating. Conclusion: Visits to the forest provided favourite places for rest, were experienced as restorative, seemed to improved reflection and may have contributed to starting the coping process for these patients. However, forest visits, as the only treatment option, are not sufficient as rehabilitation from severe and long-term ED. We suggest that forest visits should be integrated with cognitive behavioural therapy to further improve the recovery and enhance coping in daily life for these patients
