“…For example, some people may benefit from calling their friends for several hours per day, while others who use social networking apps for only a few minutes while trying to study or sleep may experience negative effects (Sohn et al, 2021). Problematic smartphone use has been associated with cognitive impairments (Wilmer et al, 2017), lower sleep quality (Demirci et al, 2015), and depression (Elhai et al, 2017;Geng et al, 2021); limiting smartphone use can reduce depression and improve sleep quality (Hughes & Burke, 2018;Hunt et al, 2018;Olson et al, 2021). However, researchers continue to debate about the precise relationship between smartphone use and various aspects of well-being (Davidson et al, 2020;Przybylski, 2019;Twenge et al, 2020) as well as whether problematic smartphone use constitutes a behavioural addiction (Kardefelt-Winther et al, 2017;Panova & Carbonell, 2018;Satchell et al, 2020).…”
