“…Epidemiological studies usually defined self-reported short and long sleep duration as less than 6 or 7 hours per day and more than 8 or 9 hours per day, respectively. 26,[29][30][31] Some researchers suggested 7 to 8 hours per day as appropriate for the university students, whereas fewer than 7 hours is defined as short sleep and more than 8 hours is regarded as long sleep. 32,33 The National Sleep Foundation has recommended 7 to 9 hours per day as the appropriate sleep duration for young adults.…”

“…Several systematic reviews on sleep duration and mortality have found that the optimal sleep duration is 7 hours, with a significant increase of overall mortality for individuals with short (≤6 hours) or long (≥8 hours) sleep. [1][2][3] In a critical review, Kurina et al 4 argue that results from the literature are not totally consistent. The analysis of Kurina et al included 42 studies and only 14 of these showed a U-shaped relationship, while 23 studies (43%) showed no association at all, and the remainder showed associations for either short or long sleep.…”

“…It has been stated in recent years that besides the traditional elements of lifestyle such as diet and physical activity, an additional factor, namely sleep, is involved in metabolic processes, hormonal functions, and energy homeostasis [1]. Tests have shown that sleep duration is associated with adverse health outcomes, such as obesity [2,3], type 2 diabetes [3][4][5], cardiovascular disease [3,6], and allcause mortality [7,8]. Inadequate sleep duration may also be a risk factor of metabolic syndrome (MetS) [9][10][11].…”
