“…In this paper, lifestyle is conceptualized as comprising four behaviors: sleep, nutrition, physical activity, and relaxation (as a psychosocial behavior to cope with stress). Studies on lifestyle have extensively focused on (a combination of) sleep (e.g., Agarwal et al, 2020;Ingram et al, 2020), physical activity (Griep et al, 2015;Larsson et al, 2019), nutrition (Wu et al, 2016;Nishi et al, 2017), and psychosocial behaviors such as relaxation (e.g., Strijk et al, 2009;Van Scheppingen et al, 2015). These four factors are also included in assessment toolkits (Reis et al, 2019) and guidelines for lifestyle (Kanji et al, 2018).…”
