上游充通大￥ SHANGHAI JIAO TONG UNIVERSIT ACIE Group 7 How do College Students'Biorhythm and Sleep Habits Affect the Quality of Sleep Miguang Sun',Zihao Ding2,Yihui Hu3 ISchool of Materials Science and Engineering,Shanghai Jiao Tong University School of Materials Science and Engineering,Shanghai Jiao Tong University 3School of Materials Science and Engineering,Shanghai Jiao Tong University Abstract A lot of researches have been done to conclude effects of different patterns and habits on people's quality of sleep and it is clear that people in similar environment share similar biorhythm and sleep habits. However,little attention has been focused on college students,who are so special and different from other groups of people.Aiming at understanding the effect of college students'biorhythm and sleep habits on the quality of sleep,questionnaire and hands-on experiments are conducted in this research project.Results suggest that most college students have unique sleep pattern compared to other groups of people.In addition,we can see that several biorhythm and sleep habits can cause some positive or negative effects on our quality of sleep,which gives us guidance on how to improve college students'quality of sleep.
