Environmental changes during critical periods of immune development are implicated in the rise of allergic disease. Increasing indoor lifestyle with reduced sunlight exposure and vitamin D production has been one proposed factor. This thesis investigated effects of postnatal vitamin D supplementation and sunlight exposure on allergic disease outcomes in early childhood. There was no difference between vitamin D supplemented and placebo groups in a randomized controlled trial design. However, children with eczema had less UV-light exposure. More studies are needed to understand the role of safe levels of UV-light exposure for allergy prevention in early life.
