“…Empirical studies have found that insufficient sleep, which is typically measured as less than eight hours per day of sleep among teenagers, is associated with adolescent increased mental health, physical health problems and poorer school performance (Chaput et al, 2016;Henderson et al, 2019;Master et al, 2023;Quach et al, 2016).
