Bright Start: Daylight Exposure Advantages in the Early Years

Every child deserves a Bright Start. As bright as daylight. Yet the amount of daylight children receive in their early years varies widely and is shaped almost entirely by the attitudes, routines and decisions of those who care for them.

This project aims to understand, evidence and ultimately improve daylight exposure in early childhood. From infancy to early schooling, children have little agency over where they spend time. In the first year, the primary caregiver’s attitude to going outdoors is decisive. Later, choices around childcare and schooling determine whether learning and play happen outdoors, indoors by a window, or under electric light. These early patterns matter: they shape habits, health and wellbeing for life.

Children naturally want to be outside. Outdoor play supports confidence, creativity, social development and independence. However, provision depends on adult awareness and priorities. A key barrier may simply be lack of knowledge about the importance of daylight, for children and carers alike. As with public health messaging around breastfeeding, cultural change requires clear, trusted evidence.

The project has four core goals. Firstly, to review and define evidence on the benefits of daylight in the early years, identifying measurable health, behavioural and educational outcomes and testing ideas through carer’s surveys. Secondly, to explore how carers’ attitudes, cultures and childcare types influence children’s time outdoors. Thirdly, to examine how building typologies and design choices in homes and nurseries affect daylight access, identifying risks and opportunities for healthier environments. Our final goal is to co-design educational material and resources through participatory workshops with different stakeholders and children.

By combining science, social insight and spatial analysis, the project seeks to lay the groundwork for guidance that makes daylight a recognised foundation of a healthy childhood.
