When COVID-19 was identified as a pandemic in March 2020, lockdowns were requested by many nations around the world. The goal of this study was to review the literature on the impact of lockdown procedures implemented in response to the COVID-19 pandemic on children's and adolescents' sleep patterns and quality. We searched the pre-print, Embase, Ovid, Global Health, Google Scholar, and Web of Science databases. Additionally, we incorporated ad hoc studies conducted on children and adolescents (aged 19 years) exposed to COVID-19 lockdown and reported on various sleep quality outcomes, including risk, protective factors, and impact on psychological and mental health. According to the review, the Covid 19 pandemic significantly impacted children and adolescents' sleep quality, causing everything from insomnia to hypersomnia and negatively affecting their physical and mental health.
