Since the evolution of the internet in 1969 and the inception of the personal computer in the early 1970s, a significant body of research has emerged that highlights the impacts of digital technology on education, health and human development. There is extensive research examining the physical, mental, and social health effects on young people and adolescents as well as the impacts of digital technology on their educational achievements. The aim of the review reported on here was to examine the impact of digital technology, and more specifically the use of Bring Your Own Device (BYOD) policies in schools. BYOD allows students to bring phones, tablets and personal computers to school. Numerous components with a negative impact on physical health have been identified. Outcomes of this study will be of interest to school leaders as policy makers. There is a need for trustworthy information on which to base reviews and revisions of school policy to ameliorate the risks of digital technology. This research report is also of relevance for tertiary providers and the government with the implementation of more online learning in class and online distance learning during COVID-19 restrictions.
