Understanding Light, Technology, and Environments of Children (2025-2028)
Abstract
Light (both natural and artificial) is vital. The timing, colour (spectra), and intensity of light exposure has a profound impact on our sleep and wake cycles, alertness, and mood. However, our light environments have changed rapidly with advances in technology and urbanisation. The effect of these changes on children's sleep, cognitive function, and wellbeing is unclear. This study aims to objectively map the artificial and environmental light experienced by children, 5 - 8 years, against their sleep, cognitive function, and wellbeing. This innovative quantification, via novel wearable technology, will advance knowledge to support optimal child development and guide practice and policy around children¿TM)s light exposure and environments.
