Light affects human health and behaviour. Research has demonstrated that children are more susceptible to the effects of light than adults, however this population remains underrepresented in the literature. This systematic review reports evidence of objectively measured light exposure on health and development outcomes in children (0–12 years old). Study (n = 59) outcomes were categorised into five thematic domains. Heterogeneity of light measurement and summarisation techniques were identified. Light's effects on melatonin and activity patterns were relatively robust, while research on sleep was sparse. Mixed findings suggest a protective effect of light on myopia, and vision improvements under cooler, brighter lighting. Increased light during the daytime was broadly associated with beneficial effects on social-emotional, cognitive, and physical health outcomes. Timing, colour, and intensity of light exposures were important in understanding health and developmental effects of light. Heterogeneity in light measurement methods limits comparability across studies and should be carefully considered. Greater understanding about the effects of light on children could inform novel approaches to support children's health, sleep, and development. • Reviews a rapidly emerging field of research into the effects of light for children's health and developmental outcomes. • Lighting exposure was linked to melatonin suppression and daily activity patterns, but sleep research remains sparse. • Increased daytime light was broadly associated with ophthalmological, psychological, and physical health outcomes. • Light measurement and summarisation methods are currently heterogenous across existing literature and research fields.

THE NATIONAL QUALITY FRAMEWORK for Early Childhood Education and Care (NQF) in Australia identifies the need for services to make provision for each child's sleep, rest and relaxation within a national early years' policy framework. The framework also requires that opportunities for learning and physical health are optimised, and that the agency of each child and their family is respected. Against this background, the scheduling of a standard sleep time in early childhood education and care (ECEC) centres remains a common practice, even in rooms catering for older children for whom daytime sleep may no longer be necessary. This article draws upon existing scholarship to explore the issues and tensions associated with sleep/rest, in the context of Australian curriculum and quality standards documents. We review accounts from educators, parents and children and contemporary views regarding high-quality practice in ECEC, with an aim of supporting critical reflection on practice and continuous quality improvement in ECEC.

Background Duration and quality of sleep affect child development and health. Encouragement of napping in preschool children has been suggested as a health-promoting strategy. Objectives The aim of this study is to assess evidence regarding the effects of napping on measures of child development and health. Design This study is a systematic review of published, original research articles of any design. Subjects Children aged 0-5 years. Method Electronic database search was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and assessment of research quality was carried out following a Grading of Recommendations, Assessment, Development and Evaluations (GRADE) protocol. Results Twenty-six articles met inclusion criteria. These were of heterogeneous quality; all had observational designs (GRADE-low). Development and health outcomes included salivary cortisol, night sleep, cognition, behaviour, obesity and accidents. The findings regarding cognition, behaviour and health impacts were inconsistent, probably because of variation in age and habitual napping status of the samples. The most consistent finding was an association between napping and later onset, shorter duration and poorer quality of night sleep, with evidence strongest beyond the age of 2 years. Limitations Studies were not randomised. Most did not obtain data on the children's habitual napping status or the context of napping. Many were reliant on parent report rather than direct observation or physiological measurement of sleep behaviour. Conclusions The evidence indicates that beyond the age of 2 years napping is associated with later night sleep onset and both reduced sleep quality and duration. The evidence regarding behaviour, health and cognition is less certain. There is a need for more systematic studies that use stronger designs. In preschool children presenting with sleep problems clinicians should investigate napping patterns. [ABSTRACT FROM AUTHOR]

Night-waking is typical across infancy and early childhood, inevitably disrupting family sleep. For some children, sleep problems develop and endure throughout childhood. This systematic review focused on fathers, and synthesised the evidence pertaining to the effects of children's sleep (from birth to 12 years) on fathers' health and wellbeing. A total of 29 studies were included. Key outcomes reported for fathers were: sleep and fatigue; mental and general health; and family functioning. An association between child sleep and father's sleep was observed when child's sleep was measured via actigraphy or paternal report, but not when measured via maternal report, suggesting that mothers may not always be aware of disruptions that awaken fathers. Findings showed poorer child sleep was associated with poorer general health and wellbeing among fathers, however, associations of poor child sleep with depression were fewer, and less frequent than those reported for mothers in the same households. Poor child sleep was negatively associated with the quality of family relationships, both within the couple and between parent and child. Future studies seeking to understand the interplay of child sleep and family wellbeing should apply objective measurement of sleep and integrate formal measures of family dynamics into the study design.
