Japanese students often struggle to get enough sleep due to the strong emphasis on hard work and dedication to one’s studies, after-school activities, part-time jobs, and digital devices. Sleep deprivation can lead to negative health effects such as fatigue, irritability, difficulty concentrating, weight gain, depression and anxiety. To help ensure better quality sleep among Japanese students, parents and teachers should encourage healthy habits such as limiting screen use before bedtime, setting regular bedtimes/wake times, providing healthy snacks before bedtime (such as fruit), exercising regularly throughout the week (but avoiding exercise too close to bedtime), ensuring adequate exposure to natural light throughout the day (especially in the morning) and avoiding caffeine late in the afternoon/evening hours when possible.
