The long-term temporary school closures due to the corona crisis had a significant impact on the sleeping habits of elementary and junior high school students, and it was revealed by specially appointed assistant professor Minami Sugimoto of the University of Tokyo Institute for Future Initiatives, assistant professor Kentaro Murakami of the Graduate School of Medicine, and professor Satoshi Sasaki. I found out in my research.

 According to the University of Tokyo, the research group targeted elementary and junior high school students belonging to 14 schools and organizations in 47 prefectures nationwide. We distributed questionnaires asking about lifestyle habits after reopening, and analyzed the answers of 2020 of them.

 As a result, during long-term school holidays, some elementary and junior high school students wake up before noon and change to a lifestyle that is closer to the night type, such as having breakfast, resulting in a difference of more than 1 or 2 hours compared to elementary and junior high school students who wake up early and eat breakfast. was

 After the school reopened, it was found that the time to wake up was about 1 hour earlier and the sleep time was about 1 hour shorter.In particular, elementary and junior high school students who woke up and had breakfast late during the school holidays had a large change in wake-up and breakfast times, and a large decrease in the consumption of soft drinks.No significant changes in nutritional intake were observed.

 The research group found that elementary and junior high school students who had a lifestyle close to night owls were greatly affected by their sleep habits when school resumed, so even if similar long-term school closures occur in the future due to infectious diseases or disasters, some Elementary and junior high school students are expected to have the same impact.
