This research aims to estimate the states of sleep / wake time from measurement records of physical activity using an actigraph and to clarify the effect that sleep / wake time has on students living in a dormitory, both with and without roommates. Discoveries made as a result of the study are as follows:1) In subjects with roommates, regression in sleep-onset time and a reduction in night sleeping time were observed (p<0.01,p<0.05).2) In subjects with roommates, daytime sleep increased (p<0.1), while the average amount of activity during the day decreased (p<0.1). Furthermore, several cases were observed in which students with roommates slept approximately 1 hour during classes, something that was not observed among subjects without roommates. It was also confirmed that this had a major influence on attitude in class, etc.
