The Effect of Nature and Game Based Activities on Older People
The purpose of this study is determine the effect of nature and game based activities on happiness, spiritual well-being, frailty and cognitive status of older people in nursing home. Hypotheses of the Research H0: Nature and game-based activities don't affect the happiness, spiritual well-being, cognitive function and frailty of older people in nursing home. H1a: Happiness levels of older people in nursing home will be an increase after nature and game-based activities. H1b: Spiritual well-being levels of older people in nursing home will be an increase after nature and game-based activities. H1c: Cognitive function levels of older people in nursing home will be an increase after nature and game-based activities. H1d: Frailty status of older people in nursing home will be a decrease after nature and game-based activities.

Nationwide Research on the Rewilding of Kindergarten Yards
Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities that is associated with altered commensal microbiota and a rising burden of immunological disorders among urban children. The investigators will estimate how rewilding of kindergarten yards affects commensal microbiome, prevalence of allergies, asthma, atopic dermatitis and infections, cortisol levels, cognitive skills and plasma cytokine levels of children. Our specific aims are: To assess if rewilding diversifies health-associated skin, saliva and gut microbiota and reduces infectious diseases and atopic or allergic symptoms. Assess whether the rewilding has positive effects on cognitive skills. Assess whether the rewilding changes cortisol and plasma cytokine levels. The investigators will recruit altogether 320 (160 per treatment) study subjects aged between 1-5 to questionnaire study (Task 2), from which 120 study subjects will be analyzed more detailed using microbiological and blood samples (Task 1).

Sand Play - the Effect of Biodiversity Exposure on Atopic Dermatitis
The prevalence of atopic dermatitis has increased along with urbanization and biodiversity loss. According to biodiversity hypothesis, the main reason is urban lifestyle and reduced contact to microbial diversity. Previous studies indicate association between atopic dermatitis and exposure to natural microbes in childhood. Sand Play - the Effect of Biodiversity Exposure on Atopic Dermatitis will investigate whether the exposure to microbial diversity in sandbox reduces the symptoms of atopic dermatitis, alters commensal microbiota and modifies immune regulation in children.

Biodiversity Interventions for Assisted Living Centers
Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities, which weakens the functionality of the urban ecosystems and the well-being of citizens. This may also increase the risk of immune-mediated disorders among urban dwellers. In Biodiversity interventions for assisted living centers (BIWE 2), microbial biodiversity interventions are performed to increase biodiversity in urban housing units for people with autism spectrum disorder, disabled people and elderly. Results from the intervention trials are combined with publicly available land cover and ecological data. These are analyzed from the viewpoint of shifts in ecosystems and human well-being and immune regulation, ecological quality, and urban planning. The investigators set up an intervention study in which yards of the housing units are rewilded with diverse vegetation and decaying deadwood and plant residuals. The investigators aim to evaluate the effect of rewilding, and yard management practices on commensal microbiome, cortisol levels and well-being and salivary cytokine levels, and gene pathways.

Biodiversity Interventions for Well-Being
Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities, which weakens the functionality of the urban ecosystems and the well-being of citizens. This may also increase the risk of immune-mediated disorders among urban dwellers. In Biodiversity interventions for well-being (BIWE), microbial biodiversity interventions are performed to increase biodiversity in urban built areas. Results from the intervention trials are combined with publicly available land cover and ecological data. These are analyzed from the viewpoint of shifts in ecosystems and human well-being and immune regulation, ecological quality, and urban planning. The investigators set up an intervention study in which urban private yards are rewilded with diverse vegetation and decaying deadwood and plant residuals. The investigators aim to evaluate the effect of rewilding, and yard management practices on commensal microbiome, cortisol levels and well-being and salivary cytokine levels, and gene pathways.
