Analysis of sleep environment in Japanese young people

It is one of the most important to create an optimal sleep environment. People who lived irregular hours, i.e. shift workers, global communication tasks, typically obtain 1–2 hour less sleep than the generally accepted target of 8 hours per day.

Many work settings such as factory work, service industries, power plants, internet communication management, health care and emergency services require shift work that includes work at night. Furthermore, not only shift workers but also young smart phone device users often experience an extended period of acute sleep deprivation at the start of a new day. Most sleep deprivation studies using complex cognitive tasks require the participants to complete the tasks alone. It was effected human health care and learning performance in young people. The purpose of the current study was to investigate how sleep environment changes between high school student and university student. Jissen Womenn’s Uiversity Ethics Committee approved this survey.
