Sleep deprivation studies indicate that sleep is vital to emotional, physical and behavioural wellbeing. This study presents the results of a survey in which 945 students in Seventh-day Adventist secondary schools responded to questions about the length and quality of their sleep. The study found that: almost one half of the students were at risk of falling short of the recommended number of hours of sleep per night; toward one in every five students were averaging six or fewer hours sleep per night; the quality of sleep (in terms of better sleep habits) and the resulting levels of daytime alertness were clearly linked to having a permanent, personal space for sleep; and finally that academic performance was strongly related to measures of daytime alertness and measures of the quality of sleep habits.
