It is reported that twenty percent of Japanese people suffer from sleeping problems such as difficulty getting to sleep, arousal during sleep, and early-morning awakening. This is also thought to be true with university students who tend to have life styles that last through the night. The number of university students who come for mental health consultations about their sleeping problems are increasing. A questionnaire about sleep was conducted to university students in a class. Many students felt that they did not have enough sleep, felt sleepy during the day, and was unsatisfied with the quality of their sleep. Insomnia disorder is said to be related to depression and school refusal, and its physical and mental effects are significant resulting in, for example, difficulty adapting to campus life. On campus, it would be important to provide the students with appropriate information about insomnia disorders, and to offer early support.
