Abstract Undisturbed sleep is essential for physiological and psychological health. Children have a special need for uninterrupted sleep for growth and cognitive development. Noise is an environmental factor that affects most children, but the knowledge of how children's health, wellbeing and cognitive development are affected by noise disturbed sleep due to road traffic is very incomplete. It has been shown that although children are less likely to wake up or react with sleep cycle shifts due to nighttime exposure, they might be more likely to react with physiological effects such as blood pressure reactions and related motility during sleep. The aim of this paper is to formulate a set of hypotheses as a base for future studies into the short and long term effects of noise induced sleep deprivation on health and child development and how this effects health and wellbeing later on in life. Because the literature is still trying to understand the nature of sleep disturbance among children in general a scoping review was used to achieve this, combining conceptual issues with a description of the scarce literature on noise and sleep disturbance in children as example. Based on this a set of hypotheses was formulated. It is concluded that future studies into the health effect of environmental noise exposure in early life should address these potential hypotheses and mechanisms and pay specific attention to the mediating role of sleep related aspects, including noise in conjunction with other environmental exposures such as indoor climate and exposure to sounds and light from electronic devices.
