Conditions
Summary
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.

Interventions
Children in microbial intervention arm receive an indoor sandbox containing play sand enriched with organic leaf compost, moss and humus substances. Families also receive an indoor cultivation set including growing box, seeds, spray bottle, plant lamp and microbe rich growing medium containing organic leaf compost, moss, biochar and humus substances.
Children in placebo arm receive an indoor sandbox containing visually similar play sand modified with peat with low microbial diversity. Families also receive an indoor cultivation set including growing box, seeds, spray bottle, plant lamp and growing medium containing peat, inorganic fertilizers, and potting gravel with low microbial diversity.
