This article explores the issue of sleeping in Japanese schools, which is prohibited due to its potential risks and disruption to other students. It examines why some students still choose to sleep in school, such as lack of sleep, stress relief, boredom, avoiding socialization and trying to catch up on lost sleep. Alternatives are provided for those who cannot or choose not to sleep in school, such as power naps during lunch breaks and setting a bedtime and sticking to it consistently every night regardless of how busy the schedule is. The impact of sleep deprivation on student performance is discussed, along with recommendations for getting enough restful hours.
