上降气通大学 SHANGHAI JIAO TONG UNIVERSIT ACIE Group 7 Firstly,living habits,including sleep habits and biorhythm,especially activities before sleep,have a deep effect on the quality of sleep.One perfect example to approve the relationship between sleep pattern and behavioral habits is Theory of Planned Behavior (TBP)(Courneya, Bobick.Schinke,1999).The theory has been utilized to account for undergraduate students'behaviors before sleep within a week in Australia(Kor Mullan,2011).The study found that both habits that students develop under normal circumstances and some perceived norms(including injunctive norms and descriptive norms)will significantly influence the quality of sleep in terms of sleep length and depth. Another important factor is mental state.Usually,people will make their mental state worse when suffering from various pressure,anxiety, depression.When it comes to university students or college students, pressure that makes changes to metal state mainly comes from academic workload and community activities.Research about relationship between psychosocial work characteristics and sleep quality(Van Dongen,Maislin, Mullington,&Dinges,2003)consists of 16 longitudinal studies and found that higher job demands are associated with lower future sleep quality. They also found moderate evidence of a positive link between job controls and quality of sleep.In addition,measures of job strain or job demands are typically found to be strongly related with adverse sleep outcomes(Karasek,1992).However,they noted that the proportion of variance attributable to these job characteristics was relatively small and the results based on ordinary people were unnecessarily reasonable when range of investigation is among college students. Finally,natural environment is also a significant factor.Natural environment comprises all the external condition that will affect the process of sleep,such as lighting,sound,temperature and even the texture and disposition of bedding.For example,to draw the relationship between insufficient sleep and the natural environment,researchers investigated whether exposure to attributes of the natural environment (e.g.,green space)attenuates the likelihood of reporting insufficient sleep among US adults(Grigsby-Toussaint et al.,2015).The results indicated that access to the natural environment attenuated the likelihood of reporting insufficient sleep,particularly among men.Another instance is the research of thermal environment and thermal comfort for sleeping people(Lan Lian,2016).The researchers concluded that the current thermal comfort theories and standards are mainly concerned with people in waking state but are not appropriate for sleeping people as the sleeping people have many different requirements on thermal environment than -5-ACIE Group 7 - 5 - Firstly, living habits, including sleep habits and biorhythm, especially activities before sleep, have a deep effect on the quality of sleep.
